Crohn's disease is an inflammatory bowel disease with symptoms of abdominal pain, severe diarrhea, fatigue, weight loss, and malnutrition. The inflammation caused by Crohn's disease often spreads deep into the layers of intestinal tissue, which is both painful and debilitating, and can sometimes lead to life-threatening complications. While there is no cure for Crohn's disease, care and treatment can significantly reduce the signs and symptoms of the disease and even bring about long-term remission.

In patients with milder Crohn's disease, current guidelines recommend close monitoring while treating symptoms. This includes making dietary changes and using anti-diarrheal medications to help control diarrhea associated with Crohn's disease.

People with diabetes can experience diarrhea for many reasons, just like any other person. Diarrhea is a symptom of many diseases such as viral or bacterial infections, celiac disease, irritable bowel syndrome, and Crohn's disease. It's a side effect of some medications, such as metformin, and some sugar-free sweeteners that can cause diarrhea in some people.
