Mild cases can be treated at home with a clear liquid diet and antibiotics for about a week. In more serious cases, the person must be treated in the hospital. In this setting, the bowel is allowed to rest. This means the person should not eat or drink anything. Fluids and antibiotics are given through an intravenous line called an IV. Surgery may be needed if the bowel has holes, blockages, or abscesses. Some people may need surgery to remove part of the bowel.
Antibiotics can cause many side effects, including rashes, stomach upset, and allergic reactions. Surgery carries a risk of bleeding and infection.
Most people will recover completely. More studies of the inside of the bowel, such as X-ray tests, may be done after recovery.
Some people have repeated attacks of diverticulitis. If a classic symptom such as left-sided abdominal pain reappears, the person should see a doctor right away. Blood tests and X-ray tests may be used to monitor the disease. Any new or worsening symptoms should always be reported to the doctor.
