Overexercising and hypothyroidism

[rennnnn]

Hey guys! I was diagnosed with hypothyroidism a week ago and it's slowly making me want to jump in front of a speeding bus. I have always been overweight and just started to achieve my dream body a year ago and now I feel like I'm being denied of the chance to retain it. :( My doc hasn't put me on medication yet since he thinks it could be a reversible case because of an acne medicine I was taking (isotretinoin) which I stopped after noticing gradual acceleration of the symptoms. I have gained an absurd amount of weight in just 4 days (15 lbs.) even though I cut back on my calorie intake considerably and do intense exercise everyday.

I realize that this post is me just unpleasantly ranting but my question is is overexercising counterintuitive because it puts a lot of pressure on the thyroid? I'm getting horribly depressed over the thought of just gaining weight even if I'm doing my hardest to ward it off and I don't know what to do. I'm pushing myself to get at least 2 hours of intense cardio everyday because I'm terrified of ballooning the weight I so desperately worked myself off to just get rid of. This is the first time I've felt actually decent looking too. I guess I just wanted to have some opinions about people who are far more experienced with this disease. Thank you guys.

P.S I've been on Isotretinoin for a month and I stopped it because of extreme constipation (sorry for the details) and alarmingly rapid weight gain. I'm a 20 year old male college student btw!

"Isotretinion has been controversially shown to cause reversible hypo- and hyperthyroidism. 113-116. The effects of Vit A derivates on thyroid function still remain debating." From the book World Clinics: Dermatology - Acne by Neena Khanna, Raj Kubba

To gain so much weight in such a small period of time is likely to be just fluid (a symptom of hypothyroidism).  There are 3 youtube videos (still more episodes he has to upload on his journey) on Diet Induced Hypothyroidism. He didn't eat enough and exercised too much and caused hypothyroidism.

Why not start by posting your current thyroid hormone levels, with reference ranges, which vary from lab to lab, so have to come from your own report.  That will give us an idea of your actual thyroid status.

Also, please explain why your doctor feels that this is a "reversible" case of hypothyroidism... A brief research of Isotretinoin indicates that it "may" trigger an autoimmune response, however, once an autoimmune response has been triggered, it's NOT reversible... Once you have the antibodies, you can't make them go away and they will continue to destroy your thyroid...

The antibody tests you need are Thyroid Peroxidase Antibodies (TPOab) and Thyroglobulin Antibodies (TgAb)... You need them both because some of us have one or the other and some of us have both... If either are elevated it would the basis for a diagnosis of Hashimoto's.  

If this doctor will not agree to treat your hypothyroidism, find one who will.  Even if your hypothyroidism "does" reverse, you can stop treatment; in the meantime, you can't just continue being hypo as being hypo affect all of your body process, not just your weight.
