Symptoms

People with diverticulosis often have no symptoms, but they may have bloating and cramping in the lower part of the belly. Rarely, they may notice blood in their stool or on toilet paper.

• Tenderness, usually in the left lower side of the abdomen

• Bloating or gas

• Fever and chills

• Nausea and vomiting

• Not feeling hungry and not eating
