Nephropathy is a term used to describe any type of kidney disease or damage. This can include conditions such as diabetic nephropathy, which is kidney damage caused by diabetes, or lupus nephropathy, which is kidney damage caused by lupus. Nephropathy can also be caused by high blood pressure, infections, or autoimmune disorders. Symptoms of nephropathy can include fluid retention, fatigue, difficulty urinating, and swelling in the legs or around the eyes. Treatment for nephropathy typically involves managing the underlying cause of the kidney damage, as well as medications to help control symptoms and slow the progression of the disease. In severe cases, dialysis or kidney transplant may be necessary.
