What may result from excessive fluid removal during dialysis in patients taking antihypertensive medication?

Excessive fluid removal during dialysis can lead to hypotension, which is characterized by unusually low blood pressure. This occurrence is particularly relevant for patients who are on antihypertensive medications. When fluid is removed rapidly or excessively, it can cause a significant decrease in circulating blood volume, which may lower blood pressure to dangerous levels, especially in patients already receiving medication to manage high blood pressure.

In this situation, the body's compensatory mechanisms may not respond adequately due to the medications in use, which further exacerbates the drop in blood pressure. Symptoms of hypotension can include dizziness, fainting, and confusion, all of which are critical considerations during patient care. Adhering to appropriate fluid removal guidelines is crucial in managing the overall health and safety of patients undergoing dialysis.
