If the legs are still swollen after dialysis, the most common reason is that the ideal goal of dialysis dry weight has not been reached, indicating that there may still be excess water in the body. At this time: First, restrict water intake to avoid excessive weight gain between dialysis sessions. Second, strengthen ultrafiltration appropriately to help get the excess water out of the body. If the feet are still swollen on dialysis, it may be related to the antihypertensive drugs taken, especially calcium channel blockers, such as amlodipine and felodipine, which are commonly used in clinical practice and may have the side effect of swollen feet. Dialysis leg swelling may be due to the patient’s own heart problems, combined with heart failure, can be treated with additional cardiac drugs.
