These studies explore the links between breastfeeding and gastrointestinal illness, gut health, and diarrhoea.

Impact of breastmilk on neonatal enteral feeding outcomes

This study found that exclusive breastfeeding had a positive impact on premature babies with gastrointestinal disorders. Babies who were exclusively breastfed had shorter parenteral nutrition courses, achieved earlier full enteral feeds and were discharged from hospital significantly sooner than those who received formula.

Breastfeeding reduces the risk of infectious diseases in infancy

This study of 4,164 infants in Holland found that exclusive breastfeeding for four months and partially thereafter reduced the risk of infections in the upper respiratory, lower respiratory and gastrointestinal tracts.

Breastfeeding protection against diarrhoea and lower respiratory tract infection

This study of 18,819 infants found that exclusive breastfeeding protects against hospitalisation for diarrhoea and lower respiratory tract infection. The effect of partial breastfeeding is weaker. The findings suggest that an estimated 53% of diarrhoea hospitalisations could have been prevented each month by exclusive breastfeeding and 31% by partial breastfeeding. Similarly, 27% of hospitalisations for lower respiratory tract infection could have been prevented each month by exclusive breastfeeding and 25% by partial breastfeeding.

Breastfeeding and Crohn’s/Ulcerative Colitis

This meta-analysis supports the hypothesis that breastfeeding is associated with lower risks of Crohn’s disease and ulcerative colitis. However, the authors call for further research as only a few studies were graded to be of high quality.
