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.
