Diabetic kidney disease

Diabetes can damage vital organs in the body without causing any major symptoms. The kidneys are among the organs that can be affected. In the early stages of diabetic kidney disease, a patient may lead a normal life. However, kidney function gradually declines over time.
How diabetes damages the kidneys: The kidneys contain numerous tiny blood vessels that filter waste from the blood to produce urine. When blood sugar levels remain high, excessive pressure is placed on these tiny blood vessels. Gradually, the filtering capacity of the kidneys begins to deteriorate. Although there may be no noticeable symptoms, kidney function gradually becomes impaired.
Who is at greater risk: People with uncontrolled diabetes, high blood pressure, smoking habits, obesity, heart disease and a family history of kidney disease are at greater risk. However, even people with diabetes can protect their kidneys through regular medical care, controlling blood sugar and blood pressure and undergoing timely tests. Diabetic patients should regularly undergo UACR and eGFR tests to determine whether their kidneys are functioning properly.
What to do to protect the kidneys
- Control blood sugar and keep blood pressure at an appropriate level.
- Under a doctor’s advice, medications such as ACE inhibitors/ARBs and SGLT2 inhibitors may be used.
- Avoid excessive salt and processed foods.
- Ensure regular walking or physical activity, weight management and adequate sleep.
