He should consult with the surgeon. Also, watch what he eats and drink plenty of water. His bowels are still in shock from the surgery.
My brother is three days out of the hospital where he underwent hip replacement surgery. Now into his fifth day without a bowel movement, he had a small bowel movement this morning. He is alarmed about mucus he observed with the bowel movement.
He's also feeling bloated and has stomach distress, probably from the bloating.
Any thoughts on what may be his problem?
I would go to your doctor and tell him/her. Sometimes these are symptoms of colitis. Good luck!!!
