What's the commitment?

To achieve tight blood sugar control with intensive insulin therapy, you must follow a strict treatment regimen.

  • You'll need frequent doses of insulin. You may need an injection of short-acting insulin before each meal and an injection of intermediate or long-acting insulin before you go to bed.

    Or you may choose to use an insulin pump, which releases insulin into your body through a plastic tube placed under the skin on your abdomen. The pump delivers a continuous infusion of short-acting insulin and a bolus — extra insulin to cover an expected rise in blood sugar — before meals.

  • You must check your blood sugar often. You'll need to check your blood sugar at least four times a day, before meals and bedtime — probably more often than you're used to. It's also important to track the results of each blood sugar test.
  • You must closely follow your eating and exercise plans. What you eat has a direct effect on your blood sugar. Physical activity also influences blood sugar. Your doctor may ask you to track what you eat and how much you exercise in a detailed diary.

What are the risks of intensive insulin therapy?

Intensive insulin therapy may lead to:

  • Low blood sugar. When you have tight blood sugar levels, any change in your daily routine — such as exercising more than usual or not eating enough — may cause low blood sugar (hypoglycemia).

    Be aware of early signs and symptoms, such as anxiety, sweating and shaking, and respond quickly. Drink a glass of orange juice or suck on a few pieces of hard candy. Your doctor may recommend carrying glucose tablets.

  • Weight gain. When you use insulin to lower your blood sugar, the sugar in your bloodstream enters cells in your body instead of being excreted in your urine. Your body converts the sugar your cells don't use for energy into fat, which can lead to weight gain. To limit weight gain, closely follow your exercise and meal plans.

Is intensive insulin therapy right for you?

Intensive insulin therapy is recommended for most people who have type 1 diabetes and some people who have type 2 diabetes — but it isn't right for everyone.

Intensive insulin therapy may not be for you if:

  • You struggle with frequent or severe bouts of low blood sugar
  • You are a child
  • You are an older adult
  • You have heart disease, blood vessel disease or severe diabetes complications

Ultimately, it's up to you and your health care team to decide if intensive insulin therapy is for you. This decision should be based on the potential risks and benefits the therapy may offer for your specific situation.
