So I used to be fairly active here, then I started having increased health problems and put the weight loss on the back burner. In 2010, I started having Tachycardia, heat sensitivities, increased BP changes that were radical and I gained weight - yes, I gained weight. For years I wanted to know what the problem was. Especially since having my resting heart rate in the 140's or above as my norm for the last 1+ years. So long story short, I went on Depo Provera for Endometrisos pain, then Propranolol (beta blocker) for my tachycardia and then I was diagnosed with Graves' Disease by an Endocrinologist and I was put on Methimazole. Depo slowed weight loss, Propranolol ER stopped it, and now Methimazole is causing me to gain it. Like 13 lbs in 6 weeks. And I am eating nothing but lean ground turkey, veggies, fruit and nuts. And I am gaining. I saw one girl in a FB group state that in 3 years, she gained like 150 on Methimazole. That scares me. I'd weight approximately 400 lbs if I did that. I was shocked by the diagnosis, since of course I am not overly skinny, and I didn't lose weight with onset, I gained about what most lose with it. My Endo and online sources show approximately 20% of people gain instead of lose (supposed to be more common in people who developed it in their teens or twenties). So now I am having trouble getting in to even see my doctor due to change in transportation AKA barely have any now, am gaining weight and my hair is falling out. Is there any way to lose while on antithyroid meds? Help??

I am sorry that I don't have any answers for you, but my thyroid has gone from normal, to overactive, back to normal, to underactive then back to normal and doctors don't know why, so I am familiar with some of the symptoms you have had. I googled Graves Disease to see what it's all about and I noticed that there are several discussion boards dedicated to Graves Disease and Thyroid disorders. If no one else here on 3 Fat Chicks has answers for you, you might google Graves Disease Discussion Boards and see what comes up.
I hope you can get some help.

Take care.

Thank you, Carol. I'm in a lot of Graves' groups on Facebook, but so far I've found no one who has had luck or have helpful experiences with helping my predicament. I thought if I found anything, it'd be on here.
