Caffeine and Polycystic Kidney Disease

Polycystic Kidney Disease is a genetic condition whereby the patient is affected with the growth of multiple cysts upon the kidneys, resulting in an abnormal increase in kidney size and decrease of kidney function. Patients should avoid foods that may potentially accelerate the progression of the disease. Caffeine-containing foods and beverages are poor choices for people with PKD. Can People with Polycystic Kidney Disease Drink Coffee?

Persons with PKD should avoid caffeine due to reasons as below:
▪ It interferes with a natural substances in the body known as phosphodiesterase that helps to prevent the formation of cysts.
▪ It can cause the cysts to grow, accelerating disease progression, worsening the condition and promoting further kidney damage.
▪ Chronic consumption of it may lead to increased blood pressure, which is one of the main risks of PKD. Hypertension increases patient's risk of having a heart attack, stroke and other health problems.
