Most people with this condition are unaware of the presence of diverticula in their large intestine. In cases where symptoms are present, the patient usually experiences discomfort in the lower abdomen, tenderness in the affected area, constipation, and bloating. The presence of these symptoms may indicate the occurrence of a different medical condition or disease though, such as a stomach ulcer and irritable bowel syndrome. Moreover, a person with this condition may have had it for a few years already by the time the symptoms develop. Individuals with chronic symptoms should seek medical help, especially those that are over 40 years old.
The most common symptom of diverticulitis is abdominal pain. The most common sign is tenderness around the left side of the lower abdomen. If infection is the cause, fever, nausea, vomiting, chills, cramping, and constipation may occur as well. The severity of symptoms depends on the extent of the infection and complications.
