Hello, You can have some home remedies to relieve your husband of regular constipation. That is how you can prevent bleeding from diverticulosis. The permanent solution for diverticulosis is surgical removal. I will suggest some home remedies which can be followed. 1. Molasses: One tablespoon of blackstrap molasses before bed should help ease constipation by morning. Blackstrap molasses is boiled and concentrated 3 times, so it has significant vitamins and minerals; magnesium in particular will help relieve constipation. 2. Fiber rich food: Foods particularly high in fiber include bran cereals, beans, lentils, oatmeal, almonds, barley, many vegetables, and fresh and dried fruits. If you re constipated and taking in additional fiber, be sure to drink more water than usual to keep your stool soft and easy to pass. 3. Mint and ginger tea: Mint and ginger are both proven home remedies to help alleviate a slew of digestive problems. 4.
