It’s possible. In clinical studies of Tresiba, gastroenteritis was a relatively common side effect in people with type 1 diabetes. Gastroenteritis refers to inflammation in your intestines. This can cause stomach pain and symptoms similar to those of the stomach flu.
Also, diarrhea was a somewhat common side effect in people with type 2 diabetes who took Tresiba in clinical studies, and diarrhea and stomach pain sometimes happen together.
Mild stomach pain may go away on its own after a few days. But if you experience stomach pain that’s severe or bothers you, talk with your doctor. They may want to examine you to determine the possible causes of your pain, and they may prescribe medication or another treatment for it. The doctor may also decide to have you stop using Tresiba and try a different drug for your diabetes.
