There are two types of diabetes: type 1 and type 2. Type 1 diabetes is a non-curable condition that requires the management of your blood sugar through insulin injections. Your physician will explain all the best ways to help you do this. Type 2 diabetes is a curable and preventable condition that will go away on its own through practical and healthy lifestyle choices. The most effective ways to prevent and manage type 2 diabetes include getting more physical activity and fiber in your diet, eating whole grains, losing extra weight, and consulting your doctor for a custom plan based on your medical history.
