Both diarrhoea and constipation can happen on the Wegovy pill (oral semaglutide weight loss tablet), especially early on or after dose increases. Constipation is often caused by reduced food and fluid intake, while diarrhoea can be triggered by high-fat meals, rapid diet changes, or sensitivity during digestion changes. Most cases improve with hydration, smaller meals, and adjusting fibre gradually.

Why Digestion Changes on Wegovy Oral Tablets

Oral semaglutide can slow digestion and change appetite. When you eat less, your gut habits change too.
