What to Eat (and Avoid) for Polycystic Kidney Disease: A Complete Diet Plan

Polycystic Kidney Disease (PKD) is a genetic disorder characterized by the growth of fluid-filled cysts in the kidneys, potentially leading to kidney failure. While there is no specific cure for PKD, adopting the right diet can support kidney health and slow disease progression. What to eat for Polycystic Kidney Disease and what to avoid to manage the condition effectively.

What is Polycystic Kidney Disease?

Polycystic Kidney Disease (PKD) is a genetic disorder characterized by the development of fluid-filled cysts in the kidneys. These cysts can grow over time, potentially leading to enlarged kidneys and impaired kidney function. PKD is a progressive condition, meaning it worsens over time, and in severe cases, it can result in kidney failure.

Types of Polycystic Kidney Disease

There are two main types of PKD:

Autosomal Dominant Polycystic Kidney Disease (ADPKD):
- This is the most common form of PKD and usually manifests in adulthood, typically between the ages of 30 and 40.
- A person only needs to inherit the gene from one parent to develop the disease.
- It accounts for about 90% of all PKD cases.
Autosomal Recessive Polycystic Kidney Disease (ARPKD):
- This rarer form typically appears in infancy or early childhood.
- Both parents must carry the gene for the child to inherit the disease.

Causes and Risk Factors

PKD is primarily caused by genetic mutations passed down from parents. If one parent has ADPKD, their child has a 50% chance of inheriting the condition. For ARPKD, both parents must carry the gene for a child to be affected.

Symptoms of Polycystic Kidney Disease

Symptoms may vary depending on the severity of the disease and the type of PKD. Common signs include:

High blood pressure
Back or side pain
Blood in the urine
Frequent urinary tract infections (UTIs)
Kidney stones
Enlarged abdomen due to swelling of the kidneys
