Which factor is essential to protect the transplanted kidney?

• A. It has little impact on graft survival
• B. It is about weight loss
• C. Careful management of diabetes and hypertension
• D. It negates the need for immunosuppressants

Answer: (C)

Controlling diabetes and blood pressure is essential for protecting a transplanted kidney. Persistent high blood glucose damages small blood vessels and the filtering units of the kidney, leading to glycation, inflammation, and protein leakage that can harm the graft over time. Hypertension adds extra stress by increasing pressure inside the glomeruli, promoting nephrosclerosis and further injury to the transplanted organ. When diabetes is well managed and blood pressure is kept within target ranges (often with medications that protect the kidneys, such as ACE inhibitors or ARBs when appropriate), the stress on the graft is reduced, helping preserve function and longevity of the transplant. Weight loss helps overall health but isn’t by itself enough to protect the graft. Immunosuppressants are still necessary to prevent rejection, so the key factor here is the ongoing control of diabetes and hypertension to minimize graft-damaging stress.
