Diarrhea can be a side effect of your immunosuppressant drugs.
Cellcept, or Myfortic can cause gastro issues. So can antivirals and antibiotics.
Can you ask your drs if you can incorporate Benefiber to your diet?
Benefiber can help regulate and improve gastro probs.
Take care!
Hello and hope you are doing well.
You have not specified the results of the colonoscopy and blood tests. For the chronic diarrhea, if the stool culture showed a growth it is an infective pathology otherwise non infectious pathologies like inflammatory bowel diseases or growths have to be considered. It could also be a side effect of medications.
Hope this helped and do keep us posted.
