Why Do Patients with Kidney Failure Suffer from High Blood Pressure

why do some patients with kidney failure suffer from high blood pressure, this question concerns patients most and their family members.

At least six in 10 adults and up to one third of children with ADPKD have high blood pressure (also called hypertension). It may be the first sign of ADPKD, and may be diagnosed when kidney function is normal.

It is unclear why people with ADPKD have high blood pressure, but early and effective treatment is essential. Controlling blood pressure to the recommended target or level may slow the progression of kidney disease and lower the risk of aneurysms and stroke or heart attack. Some people can lower their blood pressure by changing their lifestyle, but you may also need medication to lower your blood pressure to the recommended level.

If blood pressure is very high or rises very quickly, it can cause headaches and problems with vision. However, most people with high blood pressure have no symptoms. So the only way to know if you have high blood pressure is to have it measured by your doctor or another health professional.

You can sometimes reach your target blood pressure and avoid the need for medication by lifestyle changes:

Lose any excess weight (the recommended body mass index is 20-25 kg/m2)
Take regular aerobic exercise, but avoid activities that could injure your kidneys and cause cysts to bleed.

Change to a low-fat diet that includes lots of fruit and vegetables.
Reduce your salt intake (but avoid ‘low salt’ or ‘low sodium’ products. These contain potassium that is harmful if your kidney function is reduced or you are taking certain medications to lower your blood pressure).

Reduce your intake of coffee, tea, cola and other caffeine-containing drinks.
Give up smoking.

Cut down on alcohol.
