What Is Metformin?
MORE Metformin is a prescription drug used primarily in the treatment of Type II diabetes. It can be used on its own or combined with other medications. In the United States, it is sold under the brand names Fortamet, Glucophage, Glumetza and Riomet. "Metformin is very often prescribed as the first step in a diabetic's regime," said Ken Sternfeld, a New York-based pharmacist. How it works "When you're diabetic you lose the ability to use the insulin you need to offset the food," Sternfeld explained. "If you eat a carb or sugar that can't be metabolized or offset by the insulin you produce, your sugar levels will be higher. Metformin and drugs in that category will help your body better metabolize that food so that insulin levels will be able to stay more in line." Metformin aims to decrease glucose production in the liver, consequently lowering the levels of glucose in the bloodstream. It also changes the way that your blood cells react to insulin. "It makes them more sensitive to insulin," said Dr. Stephen Neabore, a primary care doctor at the Barnard Medical Center in Washington, D.C. "It makes the same amount of insulin work better. It transports the insulin to the cells in a more effective way." Metformin may have a preventive health role, as well. New research presented at the American Diabetes Association 2017 Scientific Sessions showed that long-term use of metformin is particularly useful in preventing the onset of type II diabetes in women who have suffered from gestational diabetes. Because metformin changes the way the body uses insulin, it is not used to treat Type I diabetes, a condition in which the body does not produce insulin at all. Metformin & PCOS Metformin is sometimes prescribed to treat polycystic ovarian syndrome (PCOS), according to Neabore. "I Continue reading >>
