Only very mild pain from diverticulitis can be treated at home.
General measures may include:
- Avoid aspirin, spicy foods, alcohol, caffeine, and smoking.
- Avoid enemas and laxatives.
- Try a heating pad or hot water bottle on the abdomen, or a warm bath.
- For nausea, take small but constant sips of water.
- Drink clear liquids only and avoid dairy products for 24 hours. Then slowly introduce other liquids and soups prior to returning to solid foods.
- Lie down and rest.
- Try an antacid medication such as Maalox or Mylanta.
- Take any prescribed medications as directed.
- Acetaminophen for pain
