Insulin and Type 2 Diabetes

If you have type 2 diabetes and your healthcare provider just put you on insulin, you may feel upset. You may be upset that lifestyle changes and diabetes pills weren’t enough. Or you may think that you should have tried harder to manage your diabetes. But don't blame yourself. Many people with diabetes need to change their treatment plan at some point. There are benefits to this. For example, taking insulin can make it easier to manage your blood sugar. And it can prevent complications of diabetes.

Why do I need insulin now?

Diabetes changes over time. When people first have type 2 diabetes, their pancreas is often making plenty of insulin. But their bodies can't use the insulin that is made. This is called insulin resistance. It can lead to a buildup of sugar (glucose) in the blood. A healthy diet, regular exercise, and weight loss may help. When these steps aren’t enough, diabetes pills can often help. They can reduce insulin resistance. Or increase the insulin the body makes.

But after a few years, things can change. Over time the pancreas may make less and less insulin. Insulin resistance may also get worse. You may be eating right, exercising regularly, and taking your diabetes pills. But it can still be harder to reach your blood sugar goals. At this point, your healthcare provider may switch you to a different pill. Or you may need to take more than one type. You may need to take insulin shots. These shots replace the insulin that your pancreas is no longer making.

What should I know about insulin?

There are different types of insulin. These include long-acting, intermediate-acting, regular- or short-acting, and rapid-acting. Your healthcare provider will work with you to select the insulin that’s right for you. He or she will show you how to inject it and tell you how to store it. You may need to take more than 1 shot each day to reach your blood sugar goals. A new form of inhaled insulin is now available for quick doses before meals. But it must be used along with injectable long-acting insulin if you have type 2 diabetes and use long-acting insulin.

The insulin will lower your blood sugar. How quickly this happens depends on the type of insulin. And where on your body you inject it. Your provider will work with you so that you know how much insulin to take. And how close to a meal or snack you should take it.

Once you start taking insulin, you may still need to take diabetes pills. You should stick with your healthy diet and get exercise on most days. Your medicine, diet, and exercise all work together to keep your blood sugar controlled. And to keep you at your healthy best.
