Foods to Avoid with PKD And High Blood PressurePolycystic kidney disease (PKD) is a genetic disorder with numerous cysts on kidneys.High blood pressure is the first sign of PKD and also can accelerate renal function deterioration significantly.Diet plays a vital role in managing PKD and high blood pressure.As a PKD patient with high blood pressure, what foods should avoid?

How does high blood pressure occur in PKD?

One of important kidney functions is to regulate blood pressure by producing a certain hormone called renin.However,when the cysts enlarge,they will compress the adjacent kidney tissues, resulting in renal ischemia and anoxia. When the kidneys can not get enough oxygen supply, more renin will be made, thus rising blood pressure.

In addition, healthy kidneys can filter out extra fluid from body. However,if enlarged cysts replace more and more healthy nephrons, it will result in progressive renal function decline. If extra fluid builds up in body, it will give rise to high blood pressure in PKD.

In return,high blood pressure can increase the pressure against the tiny blood vessels in kidneys,thus worsening renal function further.

Foods to avoid with PKD and high blood pressure

Salty foods

Salty foods can increase the retention of fluid.Even a small reduction in the amount of salt can reduce the blood pressure to a considerable extent.Ideally,the daily sodium intake should be not be more than 24oomg/day limiting the salt intake to 6g/day.

Canned foods

The canned foods like canned fruits and vegetables are loaded in salt so they should be restricted. Before eating canned foods, you should rinse or boil them to get rid of extra salt.

Processed foods

Processed foods should be avoided in PKD and high blood pressure as they are high in salt, preservatives, and fats. Also, ready-to-eat foods should also be limited and even avoided.


The patients with PKD and high blood pressure should avoid drinking alcohol.On one side,alcohol can damage the artery giving rise to hardening and marrowing of the arteries.On the other hand, it can stimulate the growth of the renal cysts.


Caffeine products should be avoided in PKD and high blood pressure. It can narrow arteries to rise blood pressure further and also it can worsen the renal function.

As high blood pressure results from PKD,you should have treatment to treat your kidneys as a whole.Micro-Chinese Medicines Osmotherapy is an effective treatment for PKD.
