Defining constipation – what is it?

Constipation is defined as difficulty passing stools that may be infrequent (2 or less per week) and painful. In addition, stools can be hard and of a large diameter and the child may demonstrate withholding posture and behaviour.1a,2a,b

Functional constipation is a medical term for when otherwise healthy children experience constipation, with no medical conditions which may be the underlying cause.2c,3a

Constipation is unfortunately a common and distressing childhood problem.4a

How do probiotics work for childhood constipation?

Probiotics play an important role in restoring the balance of gut flora.5a,6a

In addition, probiotics might improve the time it takes for food to move through the colon. This is beneficial in constipation as hard bulky stools are difficult to pass.4d

Choosing a probiotic.

It is important to know that different types of probiotics have different health effects, the proven effect of one strain or species is not necessarily the same as another strain or species.7a,b
