Both Metformin and Byetta are approved for use in the treatment of Type 2 diabetes. These medications are also prescribed off label to treat patients who are suffering from obesity. They are also used in treating PCOS or polycystic ovarian syndrome. Before you decide to use any of these medications to lose weight, it is best to discuss this with your doctor.
Weight gain is one of the biggest concerns of people who have diabetes. Unfortunately, some medications used for treating the condition can lead to weight gain, which makes the situation worse. Including Metformin or Byetta to your medication regimen not only helps in treating your diabetes, but also helps in promoting weight loss. However, both these medications need prescription. Thus, you need to first get approval from your doctor before you can take any of them.
