Dialysis can keep the patients alive, but they often experience an array of complaints. Headache and vomiting are commonly seen in dialysis.
Causes of headache and nausea in hemodialysis
Hemodialysis is a procedure, in which blood is removed from the body and filtered through an artificial kidney. Then, the filtered blood is returned to the body.
As hemodialysis can cause a big change in haemodynamics, it is very likely to cause changes of blood volume in body. For this reason, blood pressure can fluctuate easily. Fluctuation of blood pressure is a common cause of headache in hemodialysis.
If the patients start to have dialysis recently, dialysis disequilibrium syndrome may occur. In Kidney Failure, high levels of toxic products not only linger in blood, but also can filter into body cells. Hemodialysis can clear off the waste products from blood after several rounds of treatments. However, the harmful substances in body cells can not be cleared away. As a result, fluid in blood vessels will infilter into brain cells, thus leading to brain edema. This condition can contribute to headache and even cause death.
As mentioned above, fluctuation of blood volume is a contributor of nausea and vomiting in hemodialysis patients.
In addition, if dialysis is not performed adequately, high levels of waste products will linger in body. It is also an inducing factor of vomiting in hemodialysis.
If you have any question, you can consult with our online doctor for some medical suggestions now.
