For the past week or so, I've been feeling a little more lethargic than usual, really depressed due to unexplained weight gain (a ridiculous 18 lbs. in a week) even though I'm an obsessive fitness nut, and experiencing bad constipation issues. I've scoured the net for information regarding these symptoms and found out about hypothyroidism. I don't experience hair loss at all and I think my sensitivity to the cold is just something in my head because I'm paranoid I have the condition, however.
The kicker, and what I'm most concerned about, is the fact that I consumed tofu almost everyday for the past 2 months as my main protein source. I found out that the isoflavones is soy products can affect thyroid functioning and now I'm beating myself up for possibly afflicting myself with this condition singlehandedly. I've since stopped consuming soy products (almost a week now) so is there a chance my thyroid could heal itself in the absence of the isoflavones or do I have to get checked out? I want to go to my GP just to be sure but my mom just thinks that I'm getting worked up for nothing and refuses to have me get my bloodwork done. I'm a 19 year old guy and at a relatively healthy weight. Thanks in advance guys and I hope you're all doing well.
