Stage 4 chronic kidney disease is featured as sever decline of GFR(glomerular filtration rate) and kidney function. Usually, dialysis is used to patients with stage 4 chronic kidney disease to relieve symptoms. But some patients may suffer from dizziness after dialysis. Then what is the cause of dizziness after dialysis?

Side-effects of dialysis.

Dialysis is regarded as an artificial kidney, the main function of dialysis is to help kidneys finish some jobs that kidneys have lost. At stage 4 chronic kidney disease, the kidneys cannot well filter the waste products and toxins in blood as well as extra water. Dialysis is used to do these jobs. It can help kidney discharge some of the waste products and toxins and extra water. But dialysis can also bring a series of side-effects, such as nausea, vomiting, fatigue, muscle cramps and low blood pressure.

What is the cause of dizziness after dialysis?

As I mentioned above, dialysis will cause low blood pressure, while low blood pressure is the main cause of dizziness. Then how does low blood pressure occur? Too much water is removed from blood during dialysis. The sudden drop of water in blood will cause low blood pressure, which will trigger many symptoms, like dizziness, fatigue, poor appetite and so on.

Some patients with stage 4 chronic kidney disease may experience high blood pressure. The doctor will prescribe them some antihypertensive drugs. Taking antihypertensive drugs before dialysis is also a cause of low blood pressure.

So patients with stage 4 chronic kidney disease on dialysis should well control the water intake so as to keep a good dry body weight. Do not take antihypertensive drugs before dialysis. If you have dizziness after dialysis, you are suggested to tell your doctor immediately. For further information, you can ask the online doctor or leave a message below!
