Good Day Doctor!
My father had a crush injury on right foot about 4 months ago. He was operated and rods put into his leg and foot with external fixator. While the rod was still in doctors try to create his toe again and so grafting was done. He used to get dressing done daily for almost 2 months so that the hanging heel could fix nicely to the foot. But about 3 weeks ago the doctor advised to amputate his foot and a below knee amputation was performed. Since the time he has been amputated he is suffering from loose motions and has bowel movements 7-8 times a day. Doctor suggested an antibiotic along with a diarrhea capsule but later advised to stop taking it. But the bowel movement continues.

Could you please suggest the possible reasons and remedies.
