Gastrointestinal
complications are common after kidney transplantation and are an important
cause of morbidity in transplant recipients. These complications arise from
multiple mechanisms, including immunosuppressive drug toxicity, opportunistic
infections, metabolic disturbances, and pre-existing gastrointestinal diseases.
Post-transplant diarrhea is the most frequent clinical manifestation and may
interfere with the absorption of immunosuppressive medications. Upper
gastrointestinal disorders, such as gastritis and peptic ulcer disease, are
also frequently encountered, particularly in patients receiving corticosteroids
or antithrombotic therapy. Acute pancreatitis is less common but remains
clinically relevant because of its potential severity. This chapter reviews the
epidemiology, pathophysiology, clinical presentation, diagnostic evaluation,
and management of gastrointestinal complications after kidney transplantation,
with particular emphasis on post-transplant diarrhea and pancreatitis.
