You should feel better within two or three days of starting the diet and antibiotics.
If you haven't started feeling better by then, call your doctor. You should also contact your doctor if:
- You develop a fever
- Your abdominal pain is worsening
- You're unable to keep clear liquids down
These may indicate a complication that requires hospitalization.
The diverticulitis diet has few risks. However, continuing a clear liquid diet for more than a few days can lead to weakness and other complications, since it doesn't provide enough of the nutrients your body needs. For this reason, your doctor will want you to transition back to a normal diet as soon as you can tolerate it.
