Frequently asked questions
What is the difference between diverticulosis and diverticulitis?
Diverticulosis just means the pouches are present, often causing no symptoms. Diverticulitis is when a pouch becomes inflamed or infected, causing pain and fever.
Can I prevent diverticulitis?
A high-fibre diet, plenty of fluids, regular exercise, a healthy weight and not smoking all lower the risk of flares.
