My father in law has cll had 2nd chemo treatment last week he felt constipated yesterday drank mettamucell got diariah what shld he take no appetitite?

See MD: Your father-in-law should contact his doctor and let the doctor know what is going on. Most importantly is to keep fluids going in--any fluids--as diarrhea will deplete fluids and this must be replaced. He might benefit from simple foods for now--as applesauce and baked potato with spices to make him comfortable.. I would not use greasy or fried foods at his time. Hope this helps.
