The risks of dialysis in the elderly mainly include hypotension and allergic reactions, but the probability of occurrence is relatively low. 1. Dialysis requires the removal of water from the body, whether it is hemodialysis or peritoneal dialysis, which may cause hypotension due to excessive water filtration; in addition, the elderly are hemodynamically unstable, and a drop in blood pressure may occur during dialysis. 2. Individual blood patients may have allergic reactions, which are rare nowadays due to the better biocompatibility of dialyzers. Despite the risks of dialysis, it is one of the treatments for uremia, and patients actively cooperate with their medical professionals.
