Kidney disease, also known as renal disease, refers to a condition in which the kidneys are damaged and cannot filter blood as well as they should. This can lead to a buildup of waste and excess fluids in the body, causing various health complications.

Kidney disease can affect individuals of all ages and backgrounds. However, certain factors such as diabetes, high blood pressure, heart disease, and a family history of kidney failure can increase the risk of developing kidney disease.

Common symptoms of kidney disease may include fatigue, swelling in the legs, ankles, or around the eyes, decreased urine output, difficulty concentrating, and loss of appetite. However, in the early stages, kidney disease may not cause noticeable symptoms.

Kidney disease is diagnosed through a combination of medical history review, physical examination, and various tests such as blood and urine tests, imaging tests, and kidney biopsy. Treatment for kidney disease aims to slow the progression of the condition and may involve medications, lifestyle changes, dialysis, or kidney transplant, depending on the severity of the disease.
