Well finally got my 13 yr son on metformin his thryoid dr had finally put him on it. The new kids program (obesity clinic) refuse to put him on it and even talk with his thyroid nurse practioner and got her to agree also not to put him on metformin. We usually see the nurse practioner at the endo clinic for his thyroid but this time we got to see the dr. And she prescribed the metformin said lets give it a 6 month trial. She said with his genes from both sides of the family, the medications and his continue to gain weight. He had gain another 3 lbs since his appointment at new kids which was on jan 18 and went to see his endo on Feb. 5. She said that she has a few patients on it one who had seen no difference at all. She said if it does not show a difference in 6 months she will probably take him off it. So I am hoping we see progress with it. He also has a high insulin level at 35 suppose to be under 15. She said to see how Willy does before bringing his sister in for a new patient. So any experiences with metformin for the weight gain or weight loss for our kids?? Sorry haven't been around husband sister had died a week ago and had funeral on friday.
