Abstract
Hemodialysis can help your body control blood pressure and maintain the proper
balance of fluid and various minerals — such as potassium and sodium — in your body.
Normally, hemodialysis begins well before your kidneys have shut down to the point of
causing life-threatening complications
Description
Hemodialysis often involves fluid removal (through ultrafiltration), because
most patients with renal failure pass little or no urine. Side effects caused by removing too
much fluid and/or removing fluid too rapidly include low blood pressure, fatigue, chest pains,
leg-cramps, nausea and headaches. These symptoms can occur during the treatment and
can persist post treatment; they are sometimes collectively referred to as the dialysis
hangover or dialysis washout. The severity of these symptoms is usually proportionate to the
amount and speed of fluid removal. However, the impact of a given amount or rate of fluid
removal can vary greatly from person to person and day to day. These side effects can be
avoided and/or their severity lessened by limiting fluid intake between treatments or
increasing the dose of dialysis e.g. dialyzing more often or longer per treatment than the
standard three times a week, 3–4 hours per treatment schedule
