Infant Constipation

7 mins


Research shows that functional gastrointestinal disorders (FGIDs) occur in up to 55% of all infants in the first 6 months of life.1

FGIDs include a number of symptoms that affect the gastrointestinal tract in otherwise healthy infants.2 These symptoms are often frequent, age dependent, and related to the on-going physiological development of the gut that occurs naturally after birth. Although they usually resolve as the infant matures, they can cause considerable distress and anxiety for the parents as well as the infant.

Signs of constipation in babies

Constipation is defined as a decrease in the frequency of bowel movements characterised by the passing of hardened stools which may be large and associated with straining and pain.3
There is a wide variation in bowel movement frequency among infants – some pass stools several times a day, others only a few times a week. Parents will learn to recognise the patterns specific to their baby.

Common signs of constipation in babies can include following signs and symptoms:

  • Loss of appetite
  • Lack of energy
  • Being irritable, angry, or unhappy
  • Foul-smelling wind and stools
  • Abdominal pain and discomfort

Infant constipation – advice for parents and caregivers

NICE recommendations advise that dietary changes and ensuring adequate fluid should be in combination with medical and behavioural treatments. Dietary intervention should not be used as first line treatment4.
Parents should seek advice from their GP. A laxative (usually an osmotic) may be prescribed – followed, if necessary, by a stimulant.

For babies not yet weaned

  • Bottle-fed babies may be given cooled boiled water – the amount is calculated upon a baby’s weight and is usually given following feeds; it is important to not dilute the formula feeds5
  • Try gently moving the baby’s legs in a bicycling motion; gentle massage of the stomach may also help to stimulate the bowels5

For babies now eating solids

  • Babies should be given cooled boiled water or diluted fruit juice
  • A diet rich in fruit and vegetables can help (best fruits are apples, apricot, peaches, pears, plums, prunes, raspberries and strawberries). All foods should be prepared as appropriate for the developmental stage of the infant

The World Health Organisation (WHO) has recommended that pregnant women and new mothers be informed on the benefits and superiority of breastfeeding – in particular the fact that it provides the best nutrition and protection from illness for babies. Mothers should be given guidance on the preparation for, and maintenance of, lactation, with special emphasis on the importance of a well-balanced diet both during pregnancy and after delivery. Unnecessary introduction of partial bottle-feeding or other foods and drinks should be discouraged since it will have a negative effect on breastfeeding. Similarly, mothers should be warned of the difficulty of reversing a decision not to breastfeed. Before advising a mother to use an infant formula, she should be advised of the social and financial implications of her decision: for example, if a baby is exclusively bottle-fed, more than one can (400 g) per week will be needed, so the family circumstances and costs should be kept in mind. Mothers should be reminded that breast milk is not only the best, but also the most economical food for babies. If a decision to use an infant formula is taken, it is important to give instructions on correct preparation methods, emphasising that unboiled water, unsterilised bottles or incorrect dilution can all lead to illness.
