Insulin and weight gain: Keep the pounds off

Insulin and weight gain often go hand in hand, but weight control is possible. If you need insulin therapy, here's how to minimize — or avoid — weight gain.

Weight gain is a common side effect for people who take insulin — a hormone that regulates the absorption of sugar (glucose) by cells. However, controlling your weight is not only possible, but also an important part of your overall diabetes management plan.

Glucose that your cells don't use accumulates as fat.
