Constipation
Overview
Constipation is associated with difficult or painful passage of stools and delayed frequency of stools that lasts at least 2 weeks. [Levy: 2016] [Varier: 2013] Normal stooling patterns change as children age. Newborns typically pass their initial stool (meconium) in the first 2 days. The pattern in infants can range from multiple stools daily to 1 stool every 10-14 days; the latter is more common in breastfed infants. During toilet training, children may have more episodes of constipation as they learn to attend to their body’s signals. For children ages 4 and older, 1 daily stool is typical. Stool consistency is considered normal when the stools are soft and mushy or formed. About 85% of people have a hard stool (fecal ball) present in the rectum after waking up, which is not the same as being constipated. [Varier: 2013] Although constipation may have several etiologies, functional constipation, which involves no underlying medical condition, is the most common type experienced by children.Other Names & Coding

Prevalence
The prevalence of constipation in children is about 12%. [Mugie: 2011] Constipation is responsible for 3% of all primary care visits for children and 10-25% of pediatric gastroenterology visits. [Tabbers: 2014]Genetics
Numerous genetic syndromes are associated with childhood constipation. Genetic factors are also thought to play a role in functional constipation, but linkage studies, association studies, and direct gene sequencing have yet to find associated gene mutations. [Peeters: 2011]Prognosis
Most children with functional constipation require prolonged treatment. In one study, after intensive initial medical and behavioral treatment, 60% of children were treated successfully at 1 year of follow-up and 80% at 8 years. One-third of the children needing follow-up beyond puberty continued to have severe complaints of constipation. [van: 2003]Practice Guidelines

Roles of the Medical Home
The goals of constipation management by the medical home clinician include early recognition and effective management to prevent unnecessary emergency room visits and hospitalizations, as well as morbidity and mortality related to severe constipation. Successful therapy requires prevention and treatment of fecal impaction with oral laxatives or rectal therapies, increased dietary fiber, family education about withholding behaviors, and behavioral interventions. [Nurko: 2014]Clinical Assessment
Overview
Constipation can occur for several reasons:- Poor involuntary or voluntary neurologic control and muscle coordination in the GI tract, which can be due to chronic overstretching from retained or backed-up stool, surgical disruption, abnormal anatomy, and decreased neuroregulation
- Dietary factors including inadequate fluid (especially water); inadequate fiber (found in whole grains, fruits, and vegetables); constipating foods (such as infant rice cereal, bananas, and cheese); lack of stimulating foods (such as prunes, or apple and pear juice); and unstructured grazing (instead of eating regular meals, thus losing the peristaltic stimulus of a food bolus)
- Emotional factors including anxiety over painful stools, withholding behaviors that develop after having painful/hard stools, toileting accidents or stressful training, anxiety about asking to use the bathroom, and difficulty relaxing while in the bathroom
- Lifestyle factors including inadequate exercise and lack of access to unhurried toilet time after meals or when the rectum feels full
- Intake of certain medications (antacids with calcium or aluminum, antidepressants, antihistamines, narcotics, some antihypertensives, anticonvulsants, and antipsychotics) or iron supplements (however, the iron fortification in infant formula is not considered a contributing factor). See Medications That Can Affect Colonic Function (IFFGD) for a more complete list.
Pearls & Alerts for Assessment
Red flags for organic diseaseConsider further causes of constipation if there is delayed passage of meconium; onset <1 month of age; vomiting with abdominal pain or distension, or bilious vomiting; blood mixed into the stool; pain causing night awakenings; or weight loss.
When to referReferral to a subspecialist is recommended only when there is concern for organic disease or when the constipation persists despite appropriate therapy.
Causes of fecal incontinenceWhile fecal incontinence (including soiling and encopresis) usually is due to constipation, 20% of incontinent children actually have non-retentive fecal incontinence (defined as socially inappropriate loss of control of the bowels not caused by constipation or another medical condition). [Koppen: 2016]
Screening
Presentations
Presentations may involve:- Straining in toddlers and older children, although in infants, straining and crying to pass normal, soft stool (known as dyschezia) is common and should improve once the infant has more muscle coordination
- In toddlers and children, behaviors that reflect attempts to not pass stool, such as standing and/or crossing their legs while straining, or hiding when they need to pass stool
- Infrequent stools for the child’s age and/or very irregular patters of stooling
- Tearing/bleeding from the rectum (anal fissures, hematochezia)
- Fecal soiling due to leakage around large, obstructing stool and decreased sensitivity and awareness of the presence of stool at the anus. Soiling (stool staining in the underwear) and encopresis (loss of full-size stool) are often used interchangeably and are both included in the term “fecal incontinence” used in current literature and guidelines.
- Pebbly or bulky hard stools (can clog the toilet)
- Withholding and/or accidents due to anxiety about painful stools
- Onset of abdominal pain with meals, due to stimulation of the gastro-colic reflex resulting in cramping as peristalsis meets firm stool that is hard to move
- Less commonly, vomiting or reflux
Diagnostic Criteria
According to Rome IV diagnostic criteria for the Neonate/Toddler, diagnosis must include 1 month of at least 2 of the following in infants up to 4 years of age: [Benninga: 2016]- Two or fewer defecations per week
- History of excessive stool retention
- History of painful or hard bowel movements
- History of large-diameter stools
- Presence of a large fecal mass in the rectum
- At least 1 episode/week of incontinence after the acquisition of toileting skills
- History of large-diameter stools that may obstruct the toilet
- Two or fewer defecations in the toilet per week in a child whose developmental age is at least 4 years
- At least 1 episode of fecal incontinence* per week
- History of retentive posturing (standing or sitting with legs crossed or straight and stiff in order to avoid passing stool, or hiding and becoming red in the face while straining to hold in stool) or excessive volitional stool retention
- History of painful or hard bowel movements
- Presence of a large fecal mass in the rectum
- History of large diameter stools that can obstruct the toilet
*Of note, while constipation causes the majority of childhood fecal incontinence (including soiling and encopresis), 20% of incontinent children actually have non-retentive fecal incontinence (defined as socially inappropriate loss of control of the bowels not caused by constipation or another medical condition). [Koppen: 2016]
Differential Diagnosis
Differential diagnoses can include:- Normal stooling
- Normal early childhood developmental phase (typical for kids ages 16-24 months)
- Non-retentive fecal incontinence
Medical Conditions Causing Condition
Medical conditions that may cause constipation include:- Hirschsprung disease
- Diabetes
- Spina bifida
- Cerebral palsy
- Autism
- Hypothyroidism or electrolyte disturbances
- Developmental delays
- Tube feeding
- Anxiety (fear of using public restrooms, asking permission to go to bathroom at school, etc.)
- Inadequate intake of fluid and nutrition or excessive vomiting (not enough in, not enough out)
- Drug, supplement, or toxin effect
- Obstruction or pseudoobstruction
- Botulism
- Celiac disease
- Irritable bowel syndrome
- Specific dietary protein allergy
- Anatomical malformations or masses of the intestinal tract
- Spinal cord dysfunction, tethered cord
- Multiple endocrine neoplasia type 2B [Tabbers: 2014]
- Sexual abuse [Philips: 2015] [: ]
History & Examination
Current & Past Medical History
General questions:- Was there passage of meconium after 48 hours of birth?
- Is there a difficulty or delay in stooling that has been present at least 2 weeks?
- What is the consistency and appearance of the stool? Communication about different stool consistencies can be made simpler
using stool scales or by looking at samples or pictures that families bring to discuss. Check if there are hard, pebble-like,
or fragmented stools.
- Stool scales used for children include the Bristol Stool Form Scale (
383 KB) (free), Lane Scale (free), and Amsterdam Infant Stool Scale (figure 2, available for a cost). [International: 2016] [Tabbers: 2014]
- Stool scales used for children include the Bristol Stool Form Scale (
- Are any of the following present?
- Infrequent stooling that is associated with pain
- Is the pain associated with sense of urgency to stool, and is the pain relieved with passage of stool?
- Sharp, cramping abdominal pain
- Typical location is near the belly button or lower left or right side.
- Typical timing is intermittent daytime pain, during or shortly after a meal (typically dinner), or with exercise.
- Stool withholding or fear of passing stool
- Stool leaking/fecal soiling (involuntary staining of the underpants, also known as encopresis) or stool accidents not appropriate for developmental age. [Hyams: 2016] Soiling is more commonly associated with constipation, whereas loss of full size stool may be associated with functional non-retentive fecal incontinence (FNRFI). [Koppen: 2016] Fecal incontinence that occurs without evidence of stool retention or slowed colonic transit time, or is in conjunction with urinary incontinence, or is associated with stress or trauma in the child’s life, should trigger the clinician to consider a diagnosis of functional nonretentive fecal incontinence.
- Toilet clogging (large, bulky stools)
- Dyschezia
- Sense of incomplete bowel movements/unable to fully empty
- Early satiety/fills up fast, sense of bloating or nausea, prefers to snack rather than have full meal
- Irritability when no stool has passed recently
- School absence related to constipation or abdominal pain
- Infrequent stooling that is associated with pain
- What is the toileting schedule or pattern? The Stool Diary Using Bristol Stool Form Scale (NIH) (
147 KB) can help families record this information.
- What is the timing and composition of meals, snacks, and fluid intake? A 3-day intake diary may be useful to review.
- Is there excessive milk or juice intake?
- Is there a pattern of eating small amounts throughout the day (grazing pattern of eating)?
- Ask about frequency of exercise. For children with limited mobility, ask about time in standers or walkers.
- Identify chronic illnesses and medical conditions, including prior procedures and surgeries. Obtain information about any prior GI studies or tests and any medical providers already consulted for this issue.
- Identify all over-the-counter and prescription medications, fiber, and natural remedies used.
Physical Exam
General
Perform visual exam for fissures, hemorrhoids, fistula, tags, prolapse, or abnormal positioning and whether they are on or off the midline position. Although a routine rectal exam is not recommended to diagnose functional constipation, the exam may be needed to exclude or evaluate other conditions (e.g., Hirschsprung disease in infancy).Evaluate hydration status, pain status, ability to take oral fluids and medications, and mental status.
Growth Parameters
Evaluate growth curve for weight loss, short stature, or low weight for height/length or declining BMI. Failure to thrive may be an indication of Hirschsprung disease, impaction, or neurenteric problems. [Tabbers: 2014]Abdomen
Check for bowel sounds, distension, focal or diffuse tenderness, palpable fecal mass, or surgical scars.Testing
Laboratory Testing
Basic metabolic panel, celiac panel, thyroid-stimulating hormone, urinalysis, complete blood count, albumin, sedimentation rate, C-reactive protein, iron stores, guaiac, calcium, and potassium testing may be considered to evaluate for specific causes.Imaging
Abdominal X-ray is not recommended as a routine test for constipation in children, nor to confirm a successful “clean-out.” Incidental finding of stool on radiography is not independently diagnostic of constipation.Abdominal X-rays should be obtained if there is concern for bowel obstruction or perforation (2-views) or a foreign body (foreign body series). In unusual cases, studies such as barium enemas, manography, endoscopy, GI biopsies, and emptying times may be useful diagnostic tools, but these are not routinely indicated and consultation with a pediatric gastroenterologist would be advised.
Colonic transit time (CTT) may assist in differentiating between fecal incontinence that is related to constipation (in which the transit time may be slower than normal) and functional non-retentive fecal incontinence which is associated with normal CTT. CTT can be assessed via abdominal x-ray after swallowing a radio-opaque marker, or by colonic transit scintigraphy. [Koppen: 2016]

Pediatric Gastroenterology (see MT providers [16])
Refer for constipation that does not respond to treatment or for concerns of other organic gastrointestinal disease.
General Pediatric Surgery (see MT providers [2])
Refer for suspected Hirschsprung disease or acute surgical abdominal concerns, such as obstruction. In very severe cases of constipation, bowel evacuation under anesthesia may be required.
Pediatric Neurosurgery (see MT providers [2])
Refer for suspected tethered cord or other spinal anomalies.
Treatment & Management
Pearls & Alerts for Treatment & Management
Most recommended medication for maintenance therapyThe most highly recommended medication for maintenance therapy for pediatric functional constipation is polyethylene glycol (PEG). Lactulose, milk of magnesia, mineral oil, and stimulant laxatives can be added or used as second-line therapies. [Tabbers: 2014] While current guidelines support use of lactulose over the other second-line therapies, a 2016 Cochrane review found it inferior to mineral oil (liquid paraffin) or milk of magnesia. [Gordon: 2016]
Maintenance therapyPolyethylene glycol (PEG) and lactulose are considered the safest medications for daily maintenance therapy in children. [Tabbers: 2014] Maintenance therapy should be continued for several months and then gradually discontinued with monitoring of stools to make sure the tapering is tolerated. [Tabbers: 2014]
Clean-outs before maintenance therapyChildren with moderate to severe constipation typically need a “clean-out” prior to initiating maintenance therapy.
Thickeners and PEGStarch- and xanthan gum-based thickeners are used to increase the density of fluids to reduce the risk of aspiration for children with swallowing dysfunction. Recent research suggests that interactions between starch-based thickeners and PEG may result in inconsistent thickening and thus reduce their effectiveness. To date, xanthan gum-based thickeners do not seem to be affected by PEG. [Carlisle: 2016]
Offsetting costs of diapers for older childrenDiapers are a large health care expense. Generally, Medicaid will cover the cost of diapers for the incontinent child after age 3 through a home care company with a clinician’s prescription and letter of medical necessity. Less frequently, private payers can be convinced to do this.
How should common problems be managed differently in children with Constipation?
Over the Counter Medications
The cost of laxatives adds up quickly. If possible, select medications that the family’s insurance will cover; otherwise, suggest generics (store brands), coupons, or online shopping to compare prices.Common Complaints
Children often indicate the area around their umbilicus when asked to locate their abdominal pain related to constipation. When appropriate, reassure parents that their child can continue to participate in activities and attend school despite having occasional abdominal pain.Systems

Infancy
A common time for infants to become constipated is during the introduction of solid foods and cereals to the diet. Infants may express more irritability or arch their back and cry when passing hard stool. Clinicians should provide education about normal stooling patterns in infants and manage constipation when it arises. There is insufficient evidence to routinely recommend use of a probiotic or hydrolyzed formula as first-line treatments of constipation in infants; however, in infants who do not respond to laxative therapy, a 2- to 4-week trial of a hypoallergenic formula (without cow’s milk protein) may be considered. For breastfed infants, a maternal avoidance diet of cow’s milk protein could alternatively be considered.
Toilet Training
Constipation occurs more frequently in children who are toilet training. Painful stooling can lead to irritability or anxiety in children and increased reluctance to use the toilet. Clinicians should explain to parents that the development of continence of urine and of stool often do not happen simultaneously, and fecal incontinence occurs from involuntary overflow of stool and not from voluntary defiance. Clinicians can instruct parents to:
- Ensure easy access to the potty or toilet and comfort in getting on and off and while sitting.
- Provide supportive seating. The child should be able to rest his or her feet on a stool or the floor. Handles can provide additional support.
- Provide adequate time to pass stool. Many children will have better success with passing stool if they regularly take advantage of the gastro-colic reflex after meals.
- Gently encourage efforts to use the potty, and avoiding reprimanding or shaming children when they have accidents. Use of small rewards like stickers can be helpful. Keeping a stool diary can be motivating as well as informative.
Older children and adolescents may develop constipation when they attend school or are away from home. Many children feel anxious or embarrassed about using unfamiliar bathrooms to pass stool. In school, limited time and access to the bathroom makes it harder to relax and pass stool. This can result in the painful and retentive cycle of constipation described above. Parents can help children in this situation by discussing and planning ahead for bowel movements outside the home, and normalizing bodily functions to reduce any shame the child feels about stooling.
Setting a schedule to sit on the toilet for 5-10 minutes after meals, and possibly after school, may help children form good bowel habits. This time should be relaxed and not rushed. The child should be able to sit comfortably on the toilet with feet on the ground or on a stool to facilitate good positioning. Keeping a bowel diary and using incentives to reward compliance with the stool schedule may be motivating to older children as well as for younger kids who are potty training. These techniques help children with constipation but also can be utilized for treatment of functional non-retentive fecal incontinence. [Koppen: 2016]
Prevention
Although there is little supporting evidence, commonly given advice for caregivers to prevent constipation is to ensure healthy eating habits and diet, regular exercise, adequate fluid intake, and relaxed toileting, particularly after larger meals.
Grazing, particularly on low-fiber foods, may increase the risk of constipation because it 1) decreases the size of regular meals and the resulting bolus of food that should propel stool through the gut and 2) reduces the gastro-colic reflex.
Healthy eating habits and diet. A healthy diet helps ensure adequate nutrition and fiber intake and may help prevent constipation. A healthy diet includes at least 5 servings of fruits and vegetables daily in addition to peas, nuts, beans, and fiber-rich cereals and breads (not the same as “whole grain.”) Examples of particularly high-fiber foods include prunes, apricots, plums, raisins, raw tomatoes, peas, beans, broccoli, and sweet potatoes. Low-fiber or constipating foods include rice, cooked carrots, dairy products, bananas, and cereals or breads that are not high in fiber. [Healthy: 2015] Minimal recommended daily grams of dietary fiber can be estimated using the child’s age plus 5; however, newer recommendations are about 14g of fiber for every 1,000 calories in the diet. More general daily fiber recommendations are:
- 1 to 3 year olds - 19 grams
- 4 to 8 year olds - 25 grams
- 9- to 18-year-old girls - 26 grams
- 9- to 13-year-old boys - 31 grams
- 14- to 18-year-old boys - 38 grams
Recommend that children exercise daily for at least an hour. While there is lack of high-quality evidence about using exercise as treatment for constipation, children who exercise regularly are at decreased risk for constipation. [Koppen: 2015] For children with restricted mobility, encourage time spent in upright positioning, such as in a stander or walker; there is very limited evidence that this positioning, which uses gravity, may help decrease pain associated with passing stools in children with cerebral palsy. [Rivi: 2014]
Fluid intake (especially water): In the US, there are no commonly accepted recommendations for daily water intake for children. [Healthy: 2016] An Australian resource recommends: 1.2-1.5 liters (around 5-6 cups) daily of water for children ages 4-13. [HealthyKids: 2015] Some clinicians use the Holliday-Segar method to estimate daily fluid requirements for a child: [Meyers: 2009]
Holliday-Segar method for calculating daily fluid requirements:
- 100 ml/kg for the 1st 10 kg of weight
- 50 ml/kg for the 2nd 10 kg of weight
- 20 ml/kg for the remaining weight
- 100 ml/kg/24-hours - 4 ml/kg/hr for the 1st 10 kg
- 50 ml/kg/24-hours - 2 ml/kg/hr for the 2nd 10 kg
- 20 ml/kg/24-hours - 1 ml/kg/hr for the remainder

General Counseling Services (see MT providers [146])
A referral may be helpful to assist with behavioral concerns, non-pharmaceutical management of chronic pain, and anxiety, which may be contributing to constipation.
Pharmacy & Medications
Based on current guidelines, the most highly recommended medications for maintenance therapy for functional constipation are polyethylene glycol and lactulose, in that order. Milk of magnesia, mineral oil, and stimulant laxatives can be added or used as second-line therapies. [Tabbers: 2014] However the data supporting use of laxatives other than PEG are not as clear; a 2016 Cochrane review cited limited evidence for use of mineral oil or lactulose as second line treatments to PEG. Maintenance therapy should be continued for several months and then gradually discontinued as tolerated. [Tabbers: 2014] There is not sufficient evidence to support the widespread myth that laxatives cause physical dependency; although, constipation may recur in some people once the laxative is discontinued.
Polyethylene Glycol (PEG) 3350 over-the-counter oral laxative (MiraLAX) has been added to the Potential Signals of Serious Risks List (FDA). The FDA decided that no action is necessary at this time based on available information.
Oral Osmotic Laxatives
Osmotic laxatives cause the intestinal tract to hold more fluid. Side effects may include gas, bloating, diarrhea, nausea, cramping, and thirst.
Polyethylene Glycol 3350 (e.g., PEG 3350, MiraLAX, GlycoLax)
- For clean-out of fecal impaction phase: 1-1.5 g/kg/day x 3-6 days, maximum 100 g/day
- For maintenance phase: 0.2-0.8 g/kg/day (can be divided in 1-3 doses), maximum 17 g/day, often continued for several months
- H2O ratio: 1 teaspoon to 2.5 oz. liquid; 17 g to 4-8 oz. liquid or 5 g = 1 teaspoon
- 17 g = 1 capful = 1 heaping tablespoon
- Do not count the PEG fluid volume in the child’s total daily maintenance fluid volume.
- Liquid (10 g/15 mL sol) or packets: 1-2 g/kg 1-2 times daily, max 40 g, in divided doses [Tabbers: 2014]
- Phillips Milk of Magnesia original strength 400 mg/5 mL suspension [Tabbers: 2014]
- 2-5 years: 0.4-0.12 g/day or 5-15 mL/day in 1-2 divided doses
- 6-11 years: 1.2-2.4 g/day or 15-30 mL/day in 1-2 divided doses
- ≥12 years: 2.4-4.8 g/day or 30-60 mL/day in 1-2 divided doses
- PediaLax chewables
- 2-5 years: 1-3 tablets
- 6-11 years: 3-6 tablets
- Citroma or GoodSense (1.75 g/30 mL) solution
- 2-6 years: 3.5-5.25 mg (60-90 mL) daily
- 6-12 years: 5.25-12.25 mg (90-210 mL) daily
- >12 years: 12.25- 17.5 mg (195-300 mL) in single or divided doses
- Citroma or GoodSense 100 mg tablets
- >12 years: 200-400 mg (2-4 tablets) in single or divided doses
This type of laxative surround the outside of the stool with a slippery coating to enable smoother passage of stool and to keep water in the stool.
Mineral oil (e.g., Kondremol) [Tabbers: 2014]
- 2-11 years: 30-60 mL daily
- ≥12 years: 60-150 mL of plain mineral oil daily given as a single dose
This type of laxative helps mix moisture into the stool to make it softer and reduce straining. Stool softeners do not trigger more frequent stool passage.
Sodium docusate (e.g., Colace, PediaLax Liquid Stool Softener)
- In liquid (50 mg/15 mL), syrup (60 mg/15 mL), or capsules (50, 100, 240, and 250 mg)
- 2-11 years: 50-150 mg/day (single or divided)
- ≥12 years: 50-360 mg/day (single or divided)
- PediaLax [Tabbers: 2014]
- 2-11 years: 1-3 tablespoons mixed with milk or juice
The harshest type of laxative, a stimulant laxative, causes increased contractions of the gut to help move stool out within several hours. Use should be limited to a few days at most.
Senna/sennosides (e.g., ExLax, Little Tummies, Senokot) - in tablets (8.6 mg, 15 mg, and 25 mg doses), chewables (15 mg tablets), liquid and syrup (8.8 mg/5 mL) [Tabbers: 2014]
- 2-5 years: 2.5-5 mg/1-2 times daily
- 6-12 years: 7.5-10 mg/day
- >12 years: 15-20 mg/day
- 2-5 years: 167-333 mg (5-10 mL) daily
- 6-15 years: 333-500 mg (10-15 mL) daily or divided
- 2-6 years: 166.5-666 mg/day
- 6-12 years: 333-999 mg/day
- 3-10 years: 5 mg/day
- >10 years: 5-10 mg/day
These help evacuate the rectum by coating the stool and making it slippery. Stool typically is evacuated within an hour. Suppositories are not routinely advised for daily use.
Glycerin (e.g., Pedia-Lax, Fleets) - solid suppository in 1, 1.2, 2, and 2.8 mg sizes or liquid suppository (i.e., liquid delivered via rectal applicator)
- Solid suppository
- <4 months: 0.5 mg (1/2 pediatric suppository)
- 4 months--5 years: 1 mg (1 pediatric suppository)
- 6 years-adolescence: 2 mg (1 adult suppository)
- Pedia-Lax liquid glycerin suppository (2.8 mg/2.25 mL bottle)
- 2-5 years: 1 suppository given rectally x 1 via rectal applicator
- 1-2 years: 1/2 suppository
- 2-11 years: 1/2-1 suppository
- ≥12 years: 1 suppository
Enemas flush out the rectum and act more quickly than oral laxatives. Side effects can include incomplete evacuation of the fluid, which can lead to discomfort, distension, or electrolyte imbalances. There are other do-it-yourself and commercial enemas, but due to the risks, only 2 selected osmotic enemas are presented here.
Saline enema (e.g., Pedia-Lax, Fleet Saline) - The FDA announced in 2014 that using these more than once daily can result in serious harm to the kidneys and should NEVER be given to children under 2 years of age. [Tabbers: 2014] [U.S.: 2016]
- Pedia-Lax (monobasic sodium phosphate 9.5 g and dibasic sodium phosphate 3.5 g/66 mL bottle)
- 2-4 years: 1/2 bottle
- 5-11 years: 1 bottle rectally x 1
- Adult saline enema (Fleets - 19 g monobasic sodium phosphate monohydrate and 7 g dibasic sodium phosphate heptahydrate/188
mL bottle)
- ≥12 years: 1 bottle
- 2-11 years: 30-60 mL daily
- ≥12 years: 60-150 mL daily
- 2-12 years: 100 mg (1 DocuSol Kids tube)
- ≥12 years: 283 mg (1 DocuSol or Enemeez Mini tube)
- Alternative dosing [Tabbers: 2014]
- <6 years: 60 mL daily
- >6 years: 120 mL daily
- 2-10 years: 5 mg (1/2 enema) daily
- >10 years: 5-10 mg (1/2-1 enema) daily
Other oral medications are occasionally used to treat adult chronic constipation, such as lubiprostone (Amitiza), linaclotide (Linzess, Constella), prucalopride (Reselor), tegaserod (Zelnorm), and almivopan (Entereg). These medications SHOULD NOT be used in the primary care management of pediatric constipation.
Fiber/Oral Bulk-Forming Laxatives
Fiber supplements have not been demonstrated to be effective in the treatment of pediatric constipation, limited evidence shows that additional fiber improves constipation and may help in prevention. [Tabbers: 2014] Fiber is the non-digestible carbohydrate portion of many foods. Both soluble and insoluble fibers are important to digestive tract health.
Insoluble fiber helps “bulk” the stools and promotes normal contractions and motility so stools pass more quickly through the GI tract. Insoluble fiber food sources include wheat bran, whole grains (cereal, pasta, and bread), seeds, nuts, leafy greens, broccoli, and the skins of many fruits and root vegetables. Other sources are as follows:
- Methylcellulose (Citrucel) contains insoluble semi-synthetic fiber. It is non-fermentable, so not as likely as fermentable fiber to produce gas.
- Polycarbophil (FiberCon) contains insoluble synthetic fiber and is also non-fermentable.
- Fiber gummies can contain either or both soluble and insoluble types of fiber.
- Wheat dextrin (Benefiber) contains soluble fiber, which is fermentable in the gut.
- Psyllium (Metamucil) contains mostly soluble fiber, which is partially fermentable and still may cause gas.
- Barley malt extract (Maltsupex) contains soluble fiber.

Complementary & Alternative Medicine
Acupuncture and biofeedback are gaining some supporting evidence for use in adults with constipation, and there is emerging evidence for biofeedback use in adults with dys-synergic defecation. [Broide: 2001] [Rao: 2015] However, neither of these approaches is currently recommended for routine treatment of childhood constipation due to lack of supporting evidence in this population. Similarly, there is lack of evidence for use of behavioral therapy to treat children with constipation.
Current clinical practice guidelines do NOT recommend use of natural remedies or alternative therapies for treatment of functional constipation in large part because they often lack safety studies and may be unhealthy or dangerous, especially in high doses. Despite this, these are some remedies that caregivers may be using:
- Lemon juice stimulates contractility.
- Molasses by mouth can have stimulating effects. Not recommended for routine treatment of constipation. (A hospital in Utah no longer performs or recommends milk and molasses enemas due to a sentinel event.)
- Aloe is thought to help with occasional constipation, yet it can be unsafe at high doses and therefore should not be used for routine treatment of constipation. [WebMD: 2015]
- Probiotics generally do not have sufficient evidence to be used in treatment or prevention of chronic constipation; however, they are beneficial to overall intestinal health. [Thomas: 2010]
- Prebiotics are non-digestible food ingredients that help propagate healthy gut bacteria. All prebiotics are fiber, but not all fibers are prebiotic. Examples of prebiotics include inulin, wheat dextrin, and polydextrose. [Slavin: 2013]
- A 2- to 4-week trial of avoidance of cow’s milk protein (CMP) may be indicated in the child with intractable constipation that does not respond to laxatives. [Tabbers: 2014] Since CMP intolerance or allergy is not typically IgE mediated, blood levels, patch or skin prick test are not routinely recommended for diagnosis. [Vandenplas: 2015] For breastfed babies, a maternal elimination diet may be trialed.
Ask the Specialist
When do children need admission to the hospital for constipation clean-outs?
With persistence of the parents and detailed education and encouragement from the primary care provider, almost all children with constipation, including children with developmental difficulties, can do colon or bowel clean-outs at home. Reasons to send a patient to the emergency room may include suspected bowel obstruction (bilious emesis, signs of obstruction on abdominal X-ray, severe abdominal distention) or inability to tolerate any kind of oral intake.
When do primary care physicians need to refer children with constipation to the pediatric gastroenterology clinic?
Most children with constipation can be successfully managed by primary care physicians. Reasons to refer to the pediatric gastroenterology clinic include presence of alarming signs or symptoms suggestive of organic disease, relapse of symptoms after initial successful treatment, and no improvement after appropriate treatment.
Is a “stool ball” an indication for manual digital evacuation?
The only true indication for manual digital evacuation is bowel obstruction or suspected bowel obstruction due to impacted stool. Most fecal impactions can be disimpacted with oral or rectal medication. A stool ball may be present in 85% of children in the morning and is not an indication for manual digital evacuation.
