Why is blood pressure still high after dialysis?
End stare renal disease patients who are on dialysis experience high blood pressure due to many factors. The followings are the possible factors that contributes to an elevated blood pressure after dialysis:
1. Fluid overload: Kidney produces urine by discharging excess fluid out of the body. Failed kidneys can not take the fluid (water) off, thus the blood pressure is high.
2. Excess wastes in blood: For kidney failure patients who are on dialysis, their kidneys fail to keep balance of electrolyte and remove wastes in the blood. These harmful substances may deposit in vascular wall and make blood vessels stiffer, which also can cause high blood pressure.
3. EPO shot: Some dialysis patients receive EPO shot which can stimulate the bone marrow to make more blood cells. This helps to remit renal anemia, but in other ways, it contributes to elevated blood pressure.
Treatment for high blood pressure after dialysis
High blood pressure is a common complain among kidney failure patients and also a risk factor for them to develop cardiovascular diseases. Dialysis is a life-saving method for people whose kidneys have failed completely. It shows effects in prolong their life-span,but it is the only option for kidney failure patients who still have urine output.
For kidney failure patients who still have a certain kidney function, they can try Micro-Chinese Medicine Osmotherapy which is based on Traditional Chinese Medicine (TCM). Chinese herbs used in this treatment have function to extend blood vessels, which can help to bring blood pressure down. What is more, effective ingredients in micro-Chinese medicine can activate injured kidney intrinsic cells to help them recover. They show effects in repairing injured kidney intrinsic cells, but can not revive dead kidney tissues. Therefore, kidney failure can not be cured with this treatment, but kidney function can be improved. With improvement of kidney function, dialysis patients have a certain chance to reduce dialysis frequency and even get off dialysis.
Decreased kidney function is the major reason for dialysis patients to suffer from high blood pressure. Hence, as long as kidney function gets improved, high blood pressure is alleviated to some extent.
