Type 2 Diabetes and the Insulin Pump

If you have type 2 diabetes and take insulin, you may want to ask your doctor about the insulin pump.

Insulin pumps are small, computerized devices (about the size of a small cell phone) that you wear on your belt or put in your pocket that allow for a continuous flow of a rapid-acting insulin to be released into your body. The pumps have a small, flexible tube (called a catheter) with a fine needle on the end, which is inserted under the skin of your abdomen and taped in place.

Managing Diabetes with Exercise

Two years ago, when Jennifer Auyer's father died at age 64 from complications related to type 2 diabetes, she faced a turning point in her own struggle with the disease. Her father's diabetes had led to heart disease, a quadruple bypass, a foot amputation, and vision problems, among other serious health troubles. "It was a really painful experience, for him and for all of us," says Auyer, 40, of Nashua, N.H. Four years ago, she, too, was diagnosed with type 2 diabetes, shortly after giving birth...

The insulin pump is designed to deliver a continuous amount of insulin, 24 hours a day according to a programmed plan unique to each pump wearer. The user can change the amount of insulin delivered.

Between meals and overnights, a small amount of insulin is constantly delivered to keep the blood sugar in the target range. This is called the basal rate. When food is eaten, a bolus dose of insulin can be programmed into the pump. You can measure how much of a bolus you need using calculations based on the grams of carbohydrates consumed.

When using an insulin pump, you must monitor your blood glucose level at least four times a day. You set the doses of your insulin and make adjustments to the dose depending on your food intake and exercise program.

Why Use an Insulin Pump for Diabetes?

Some health care providers prefer the insulin pump for diabetes because its slow release of insulin mimics how a normally working pancreas would release insulin. One large study concluded the insulin pump is a safe and valuable treatment option for those with poorly controlled blood sugar despite multiple daily insulin injections. 

Another advantage of the insulin pump is that it frees you from having to measure insulin into a syringe.

If the level is below 70 or you are experiencing symptoms such as shaking, sweating or difficulty thinking, you will need to raise the number immediately. A quick solution is to eat a few pieces of hard candy or 1 tablespoon of sugar or honey. Recheck your numbers again in 15 minutes to see if the number has gone up. If not, repeat the steps above or call your doctor.

People who experience hypoglycemia several times in a week should call their health care provider. It's important to monitor your levels each day so you can make sure your numbers are within the range. If you are pregnant always consult with your health care provider.

Congratulations on taking steps to manage your health.

However, it's important to continue to track your numbers so that you can make lifestyle changes if needed. If you are pregnant always consult with your physician.

Your level is high if this reading was taken before eating. Aim for 70-130 before meals and less than 180 two hours after meals.

Even if your number is high, it's not too late for you to take control of your health and lower your blood sugar.

One of the first steps is to monitor your levels each day. If you are pregnant always consult with your physician.
