Diverticulitis is a condition that occurs when small pouches called diverticula in the wall of the colon become infected or inflamed. The symptoms of diverticulitis can vary in severity, but they commonly include: Abdominal pain: Usually located in the lower left side of the abdomen, although it can occur on the right side as well. The pain may be constant or intermittent and can range from mild to severe. Change in bowel habits: This may include diarrhea, constipation, or a combination of both. Some individuals may also experience a decrease in appetite. Nausea and vomiting: These symptoms can accompany diverticulitis, especially when the condition is more severe. Fever and chills: In some cases, diverticulitis can cause an elevated body temperature and feelings of coldness or shivering. Abdominal tenderness: The affected area may feel tender to the touch or when pressure is applied. It's important to note that these symptoms can resemble those of other gastrointestinal conditions, so a proper diagnosis by a healthcare professional is necessary to confirm diverticulitis. If you experience severe abdominal pain, persistent vomiting, high fever, or rectal bleeding, it is advisable to seek immediate medical attention, as these could be signs of complications or other serious conditions.
