Can Patients with PKD Drink Arabica Coffee

Arabica coffee has a long history in Arab States and it can go back to the ancient time. Arabica coffee is a high quality and healthy drink and it can lower the risk of developing colon cancer, gout, Parkinson's disease. However, for the local patients with Polycystic Kidney Disease (PKD), they should limit the coffee consumption strictly.

Firstly, caffeine in Arabica coffee has a bad influence on high blood pressure.

High blood pressure is a very common complication of PKD. Caffeine can affect the secretion of renin which can regulate blood thus resulting in a sharp rise in blood pressure. In addition, the caffeine can stimulate the adrenal gland to produce more epinephrine, which can arouse blood pressure to elevate.

Secondly, coffee can cause the cysts to enlarge.

In PKD, the tubule cell proliferation and the cystic fluid accumulation result in the increasing in number and size of cysts, which can cause the enlargement of kidneys. The adenosine 3': 5'-monophosphate (cAMP) in coffee can accelerate the above mechanisms of cysts expansion.

Thirdly, the minerals in coffee can cause renal injury.

Coffee is rich in potassium. However, in PKD, if the patients suffer from renal insufficiency, their kidneys can not achieve their fullest potential. As a result, the potassium will accumulate in body. If the potassium level is too high, it may cause heart enlargement, arrhythmia and even cause death.


Therefore, the patients in Arab States should limit the Arabica coffee consumption in their daily diet. However, it means that they should avoid drinking coffee completely.
