Hypotension During Hemodialysis

Hypotension During HemodialysisA sudden drop in blood pressure is called hypotension and low blood pressure, which is one most common side effect of hemodialysis. Along with hypotension, patients may be also affected by shortness of breath, nausea, vomiting, muscle cramps, and so on.

Why does hemodialysis cause blood pressure to decline?

As one artificial kidney, one important kidney function is to remove extra fluid from the body, but the difference is that healthy kidneys can determine how many fluid to retain in the body spontaneously, but how much fluid is eliminated from the body via hemodialysis is decided by doctors in the dialysis center. From this point, hemodialysis is unable to be as effective as healthy kidneys.

Generally, to make kidney failure patients live easier and safer with hemodialysis, doctors will firstly determine patients' dry weight before doing dialysis. However, if patients drink too much fluid during dialysis sessions, a large amount of fluid will be excreted from the body in hemodialysis treatment. This trigger hypotension easily.

Additionally, if patients take anti-hypertensive medications without doctors' guidance, patients may also have low blood pressure easily.

How to prevent low blood pressure for hemodialysis patients?

After finding out the underlying cause, the treatment should depend on the causes, and the preventions should include several aspects:

- Control the weight gain tightly during dialysis sessions

- Limit the fluid intake to make yourself live with dialysis more easily

- Never eat any hypertensive medication before dialysis treatment without doctors' guidance

- Pay attention to the change of your blood pressure closely during hemodialysis treatment

- Tell the doctor or nurse immediately if you have any discomfort
