How does diverticulitis affect body parts and the gastrointestinal tract?

Diverticulitis primarily affects the colon, specifically the diverticula—small pouches that can form in the intestinal walls. When these pouches become inflamed or infected, they can cause symptoms such as abdominal pain, fever, and changes in bowel habits. This condition can lead to complications, including perforation of the colon, abscess formation, or peritonitis, which can affect surrounding organs and the overall gastrointestinal tract function. Treatment often involves dietary changes, antibiotics, or in severe cases, surgery.
