Which of the following is a common complication during dialysis treatment?

Hypotension, or low blood pressure, is a well-documented complication that can occur during dialysis treatment. This happens for several reasons, primarily related to the removal of fluid from the blood during the dialysis process. As excess fluid is extracted, patients can experience a rapid drop in blood volume, leading to lower blood pressure. Additionally, factors such as changes in body position, the patient's overall health status, medications, and the rate of fluid removal can further contribute to this complication.

In contrast, increased appetite is generally not associated with dialysis, as patients often experience a decrease in appetite due to dietary restrictions and the effects of their kidney condition. High blood sugar can occur in individuals with diabetes but is not a common complication directly linked to dialysis itself. Weight gain can happen between dialysis sessions due to fluid accumulation, but during the treatment, patients usually experience fluid loss, not weight gain. Therefore, hypotension stands out as a significant and common concern during dialysis treatments.
