Having diabetes can mean having a greater risk for heart disease and high blood pressure, kidney disease, eye problems and nerve damage than people without diabetes. Keeping blood glucose under control from day to day and year to year can help prevent these complications, which usually appear after several years of having high blood sugars. Since people with type 2 diabetes may have elevated blood sugars for several years prior to diagnosis, there may be some evidence of complications at the time of diagnosis. You can keep tabs on your risk of diabetes complications by seeing your doctor regularly and having the tests needed to check how diabetes is affecting your body. Of course, eating healthy to prevent diabetes complications is a good strategy too. It’s never too late to take steps to prevent, manage or delay the onset of complications.
First things first, maintaining target blood sugar levels and a healthy body weight will have the greatest impact. It’s no surprise that eating healthy plays a major role in getting the blood sugars to where they should be and to achieve your goal weight. Your registered dietitian will help you to come up with a food plan to help keep your blood sugar in your target range and maintain a healthy weight. In addition, the particular foods you choose to eat can target the prevention of specific complications.

The prevention of diabetes complications involves controlling blood sugar levels, cholesterol levels and blood pressure. Regular exercise and taking medications are important parts of the plan, but making healthy food choices can go a long way to living a healthy life with diabetes.
