......."What is the appropriate diet for a person recovering from a mild attack of diverticulitis?
Deb / Virginia
Treatment of diverticulitis depends on the severity of your symptoms and whether this is your first attack. Mild cases can be treated with changes in diet, rest and antibiotics.
During a mild attack of diverticulitis, your doctor may recommend a clear liquid diet or a low-fiber diet. This helps the area of infection to heal. Once your symptoms improve ?- often within a few days ?- you can gradually increase the amount of fiber in your diet. Start by adding about 5 to 15 grams of fiber a day to allow your digestive system to adjust to the higher fiber intake.
To prevent attacks of diverticulitis:
Eat more fiber. High-fiber foods, such as fresh fruits and vegetables and whole grains, soften waste and help it pass more quickly through your colon. This reduces pressure within your digestive tract. Aim for 25 to 35 grams of fiber a day. If you have a difficult time consuming this much fiber every day, consider using a fiber supplement.
Drink plenty of fluids. Fiber works by absorbing water and increasing the soft, bulky waste in your colon. But if you don't drink enough liquid to replace what is absorbed, fiber can be constipating."

Food intake isn't vital at this stage.....the bowel is normally "rested" after this type of problem. I went without any food at all for about 6 weeks.
The only intake I had was an alternating saline, or glucose drip. It restored my teenage figure and handsome good looks, but this soon disappeared when I started scoffing food again.
If he feels like eating, make sure it is clear soup to start, and keep away from anything with seeds in it.
GET HIM TO DRINK LOTS OF WATER, THOUGH....as dehydration will make things worse.
