The Link between IBS and Diabetes

Diabetes is a condition that affects the way the body processes sugar and leads to higher amounts of sugar (glucose) in the blood. This typically occurs when the body cannot make insulin or when the cells cannot use insulin effectively. Diabetes can affect various parts of the body, including the GI tract, by damaging the nerves around the gut and causing IBS symptoms, such as bloating, gas, diarrhea and constipation.

When the nerves around the gut are damaged, the gut and the brain have difficulty communicating and the movement of the intestines may either speed up or slow down, causing issues of constipation or diarrhea. Additionally, when the movement slows down, the stomach empties slower, causing fullness and bloating. Further, heartburn may ensue when there is nerve damage in the esophagus. Lastly, those with diabetes have more difficulty breaking down sugars in the small intestine and are at higher risk for bacterial overgrowth.

The best way to treat diabetes and prevent IBS from diabetes is to eat ‘real’ foods high in fiber and avoid processed and refined foods. Additionally, avoid added sugar and sugar alcohols. Exercise regularly, reduce stress and decrease alcohol intake. If you are experiencing IBS symptoms, a low FODMAP diet may help with symptom relief.
