PKD stands for Polycystic Kidney Disease, which is a genetic disorder that causes many fluid-filled cysts to grow in the kidneys. These cysts can change the shape of the kidneys, including making them much larger, and can cause the kidneys to lose their ability to function properly over time. PKD is an inherited disorder that is passed from parents to children through genes. There are two main types of PKD: autosomal dominant PKD (ADPKD), which is usually diagnosed in adulthood, and autosomal recessive PKD (ARPKD), which can be diagnosed in the womb or shortly after a baby is born. PKD can cause other complications, such as high blood pressure, cysts in the liver, and problems with blood vessels in the brain and heart. Symptoms of PKD can include chronic pain, high blood pressure, and blood in the urine. There is no cure for PKD, but treatment focuses on preventing complications and alleviating symptoms.
