Your bowel, or small intestine, is designed to digest. But drinking alcohol can limit its efficiency.
Alcohol can trigger symptoms of irritable bowel syndrome (IBS).
Research has shown that even moderate drinking can potentially lead to bacterial overgrowth in your small intestine which may cause bloating, gas, abdominal pain, constipation and diarrhoea.
People who suffer from a wheat intolerance should avoid beer, since it often brewed with wheat.
Chronic alcohol use causes changes in the structure and function of the small intestine, disrupting its ability to digest.
