Insulin is a hormone that helps glucose get where it needs to go. When your body senses that you’ve eaten something, your pancreas produces insulin to help your cells absorb sugar. If you didn’t have insulin, your cells wouldn’t receive their glucose fuel, and your body would sense sugar in your bloodstream and eventually store it as fat because your cells didn’t use it.
Ideally, insulin should be administered in a manner that mimics the natural pattern of insulin secretion by a healthy pancreas. However, the complex pattern of natural insulin secretion is difficult to duplicate. Still, adequate blood glucose control can be achieved with careful attention to diet, regular exercise, home blood glucose monitoring, and multiple insulin injections throughout the day..
A healthy balance of carbohydrates, proteins, and fats in your diet will help keep your blood glucose on target. How much of each will depend on many factors, including your weight and your personal preferences. Watching your carbohydrates -- knowing how much you need and how many you are eating -- is key to blood sugar control. If you are overweight, either a low-carbohydrate, low-fat/low calorie, or Mediterranean diet may help you get your weight to goal. No more than 7% of your diet should come from saturated fat, and you should try to avoid trans fats altogether.
Note that these medications used to treat type 2 diabetes are typically not used in pregnant or breastfeeding women. At present the only recommended way of controlling diabetes in women who are pregnant or breastfeeding is by diet, exercise, and insulin therapy. You should speak with your health-care professional if you are taking these medications, are considering becoming pregnant, or if you have become pregnant while taking these medications.
