Why Am I So Tired With Diverticulitis

Diverticulitis is a gastrointestinal condition that occurs when small pouches called diverticula, which form in the lining of the colon, become inflamed or infected. Common symptoms include abdominal pain, nausea, and changes in bowel habits. One less-discussed symptom that many people with diverticulitis experience is fatigue. In this article, we will explore the potential reasons for feeling tired with diverticulitis and provide resources for further reading on the topic.

Reasons for Fatigue with Diverticulitis:

1. Inflammation and infection: When the diverticula become inflamed or infected, the body's immune system responds by releasing various inflammatory chemicals to fight the infection.
