Constipation<br />

Recommend<br />

Maintenance programs consisting of medication, toileting program, dietary advice<br />

and follow up to prevent recurrence<br />

Background<br />

Constipation is the difficult passage of infrequent dry, hard stools that often cause<br />

pain and discomfort. The most common cause is functional - no underlying cause [8]<br />

Constipation starts a vicious cycle - passing hard stool is painful, so the child avoids<br />

straining at stool, the constipation gets worse and so on. Part of the battle is forming<br />

a habit for the child to go to the toilet each day<br />

Straining is normal in babies<br />

1. May present with<br />

• Hard stool - often small pellets<br />

• Excessive straining at stool<br />

• Soiling (also known as encopresis)<br />

2. Immediate management Not applicable<br />

3. Clinical assessment<br />

• Obtain a complete patient history including:<br />

- - medical history<br />

- - past episodes<br />

- - current diet including food allergies [6]<br />

- - fluid intake - are they breastfeeding or on formula? how is the formula made<br />

up? (Over concentrated formula can lead to constipation.) Are they given<br />

water as well?<br />

- - what / how much is their physical activity?<br />

- - family routine (the constipated child usually has poor nutrition, poor fluid<br />

intake and is inactive)<br />

- - parental expectations of ‘normal’ stool pattern<br />

- - length of time since last passed a stool / defecated?<br />

- - describe stool, colour, consistency, frequency of defecation<br />

- - ask carer if any change in child’s behaviour?<br />

- - what is there urinary output history? are they bedwetting? daytime wetting?<br />

- - is the child on medication?<br />

• Perform standard clinical observations +<br />

- - weigh - use naked weight in young children and record against most recent<br />

- - plot growth and height / length<br />

• Perform physical examination:<br />

- - inspect mouth, look for mouth ulcer(s) and state of teeth / gums<br />

- - inspect and palpate abdomen - for masses<br />

- - ankle knee reflexes (to assess sacral nerve roots and gait)<br />

- - inspect the anus and perianal area - position of the anus, pressure of stool<br />

around anus, perineal sensation, skin tags, anal fissures<br />

• Consider possible organic problem (and refer for further work up) if:<br />

-- child has constipation from birth<br />

-- child has vomiting, and abdominal distension<br />

-- there is any bile vomiting<br />

-- the child is not growing well<br />

-- there is more than just a streak of blood on the stool<br />

-- constipation does not improve with simple measures<br />
