Polycystic kidney disease (PKD) is a genetic disorder characterized by the growth of numerous cysts in the kidneys. These cysts are fluid-filled sacs that can disrupt normal kidney function, leading to complications such as high blood pressure and kidney failure. PKD can be inherited in two main forms: autosomal dominant PKD, which is more common, and autosomal recessive PKD, which is rarer and usually more severe. Symptoms of PKD may include abdominal pain, headaches, and blood in the urine. Diagnosis is typically made through imaging tests like ultrasound or CT scans. While there is no cure for PKD, management strategies include controlling blood pressure and monitoring kidney function to help maintain quality of life.
