Hi there ~
I understand your concerns. Although meth
use and abuse is related to a lot of medical conditions and symptoms, the affect on thyroid
gland is not documented. I believe if you have concerns regards your thyroid gland being affected, it might be a good idea to go to a local doctor and have your thyroid gland checked out. I also believe that you might need to consult an endocrinologist
to see if you need other testing to find out the cause of your obesity. A nutritionist who can help with the kinds of foods to eat and an exercise specialist to get you on an exercise regimen will help in the process of losing weight.
I hope this helps. Take care and have a lovely day!
