Teen obesity is a growing health problem. The percentage of US adolescents who are overweight has more than tripled over the last 20 years. One diabetes drug may help teens lose weight.

For many diabetes patients, diet and exercise alone isn't enough to control blood sugar levels. These patients need medications. And they may need more options. A new diabetes medication is at the start of the approval process.

With all the available treatment options for type 2 diabetes, it can be hard to tell which one is right for which patient. A recent study addressed this difficulty with a comparison of two medications.

In most cases, a drug is first created to treat one disease. Later down the road, however, researchers may find that the drug can be used for other purposes - which is the case now with a certain diabetes drug.

Some diabetes drugs have to be taken multiple times a day. For many patients, it can be hard to stay on such a strict schedule. Now, patients have the option of a once-weekly drug for type 2 diabetes.
