As you may already know, controlling your blood sugar is important for avoiding hypoglycemia and hyperglycemia—blood sugar lows and highs.
By keeping your blood sugar in your target range, you may delay or prevent long-term complications. High blood sugar can damage many parts of your body, including your eyes, heart and toes. The good news is that you, along with your healthcare professional, may be able to lessen or even prevent the impact of diabetes complications on your life.
These pages list some of the more common diabetes-related complications, their symptoms and treatments, and some steps your healthcare professional may recommend to help reduce your risk.

Kidneys filter your blood through millions of blood vessels and then dispose of body waste in your urine. Diabetes can damage these small blood vessels, making it hard for the kidneys to filter your waste.
As a result, diabetes is the leading cause of kidney failure. About 30% of people with type 1 diabetes and 10%–40% of those with type 2 diabetes will eventually have kidney disease, or nephropathy.1
Smoking, uncontrolled blood sugar, or high blood pressure, you may be at increased risk of kidney disease. Having a family member with kidney disease, also increases the risk of developing kidney disease.
Detecting Diabetic Nephropathy
While there are no early symptoms of kidney damage, your healthcare professional can test for it.
Your healthcare professional will check your urine for a protein called albumin. This screening can detect nephropathy in its early stages, when treatment can slow or even prevent progression of the disease. If you have diabetes and are between the ages of 12 and 70, you should have a urine protein test at least once a year.2
