Overview

Diabetic nephropathy is a long-term complication of diabetes that damages the kidneys. It happens when high blood sugar levels damage the kidneys' tiny filtering units, called glomeruli, over time. This damage makes it harder for the kidneys to filter out waste and extra fluids over time. Diabetic nephropathy is a major cause of chronic kidney disease and kidney failure around the world. The disease usually worsens slowly and may not show any signs at first. It is very important for people with diabetes to get regular screenings so that serious kidney damage doesn't happen or is delayed.

Symptoms
Diabetic nephropathy frequently presents no discernible symptoms in its initial stages. As kidney damage worsens, people may notice swelling in their legs, ankles, or eyes due to fluid retention. Foamy pee could mean that you're losing protein. You may feel tired, lose your appetite, and have trouble focusing. In later stages, signs of kidney failure may show up.

Causes
Diabetic nephropathy is caused by prolonged high blood sugar levels that damage the blood vessels in the kidneys. High blood pressure can accelerate kidney damage. The risk goes up when diabetes isn't well controlled, when you smoke, when you're overweight, or when you have a genetic predisposition. The length of time someone has had diabetes is also important. The risk is higher after many years of poor disease management.

Diagnosis
Diagnosis includes urine tests to detect protein leaks, especially microalbumin levels. Blood tests check how well the kidneys are working and how much creatinine is in the blood. It is very important to monitor your blood pressure. Imaging studies can assess kidney structure. People with type 1 and type 2 diabetes should get regular screenings.

Treatment
The goal of treatment is to slow the disease's progress by keeping blood sugar and blood pressure under strict control. Doctors often prescribe medicines to protect the kidneys. It's important to make lifestyle changes, such as eating well, working out regularly, and quitting smoking. Managing cholesterol and reducing salt intake can help keep your kidneys healthy. Dialysis or transplantation may be required in advanced stages.

The future depends on early detection and control of diabetes. If you manage it well, progression can be slowed significantly. If not treated, diabetic nephropathy can cause chronic kidney disease and eventually kidney failure.
