Medications are an important part of relieving symptoms. Your doctor may suggest fiber supplements or laxatives for constipation or medicines to decrease diarrhea, such as Lomotil or loperamide (Imodium). An antispasmodic is commonly prescribed, which helps to control colon muscle spasms and reduce abdominal pain. Antidepressants may relieve some symptoms. However, both antispasmodics and antidepressants can worsen constipation, so some doctors will also prescribe medications that relax muscles in the bladder and intestines, such as Donnapine and Librax. These medications contain a mild sedative, which can be habit forming, so they need to be used under the guidance of a physician.

Fiber
Dietary fiber is an important component of a balanced, healthy diet. Fiber is broken down in the
colon into short chain fatty acids. The colon uses these short chain fatty acids as an energy
source. In people with Ulcerative Colitis, there is no need to limit the intake of dietary fiber.
Likewise, it is not necessary to increase fiber intake above the recommended levels for the
general population. Recommended daily dietary fiber intake is 20-30 grams. Trial and error is
the best way to figure out what amount of fiber you are able to tolerate in your diet. The amount
of fiber tolerated varies between individuals and may also vary with an individual during a UC
flare.
not saying ur dad is a liar! but he may associate fiber because of the foods that bother him, but its may not the fiber in the food that is causing his problems
again observation vs experiment
you blame the fiber in the fruit, when in fact, it may be the acidity. (considering colitis is ulceratative)
