A change of diet if that is okay with your doctor might help. Lots of fresh fruit and veggies gives more bulk. Broccoli is easy to cook. I get the crowns so I do not have to deal with the stems. Bring 1/2 inch of water to boil in the bottom of stainless steel pot and then put in broccoli crowns. Cook 5 minutes after come to boil again and turn down to medium or medium high heat. Serve with butter or salad dressing or hollandaise sauce. Should be just a little tender. If already soft fill pot with cold water and cooking will stop.

Yogurt helps the gut a lot and can turn things around.

Whole grains help as well.

Drink lots of water in the morning. That helps

Exercise or yoga or stretching.
