Which condition serves as a contraindication for hemodialysis?

Severe hypotension is indeed a contraindication for hemodialysis because this condition can compromise the patient’s ability to tolerate the treatment. Hemodialysis involves the removal of excess fluids and wastes from the blood through a machine. If a patient is already experiencing severe hypotension, undergoing the procedure can further decrease their blood pressure, potentially leading to inadequate organ perfusion, shock, and other serious complications.

In contrast, chronic kidney disease, urinary tract infections, and diabetes mellitus are not absolute contraindications for hemodialysis. Patients with chronic kidney disease often require hemodialysis as their renal function deteriorates. Urinary tract infections may be managed concurrently with dialysis, and diabetes mellitus, while it can complicate a patient’s overall health, does not prevent the initiation of hemodialysis. Therefore, severe hypotension is the most critical condition that makes hemodialysis unsafe.
