Hypotension is the most common complication associated with hemodialysis due to the rapid changes in fluid and electrolyte balance that occur during the procedure. During hemodialysis, blood is filtered through a dialyzer, and excess fluid is removed from the body. This can lead to a sudden drop in blood volume, especially if a patient has a high fluid overload prior to treatment or if excessive fluid is removed during a session.

The process can also result in shifts in blood pressure control, related to the use of medications for blood pressure management prior to or during treatment. When a patient experiences hypotension, they may exhibit symptoms such as dizziness, weakness, nausea, and even fainting, making it a significant concern for healthcare providers managing patients undergoing hemodialysis.

Understanding the dynamics of fluid removal and its effects on the cardiovascular system is crucial for dialysis nurses, as they must closely monitor patients for signs of hypotension throughout the treatment process.
