    Unexplained weight gain in teenage girl?
    AStump posted:
    Here's the deal; Ever since April pounds have been creeping up. I was around 115-120 and 5"9. I felt fine, was perfectly content. I struggled with eating disorders for around 3 years and had been back to eating regularly over a few months before April with no weight gain/loss whatsoever. Great. But since then, I have gained 20-25 lbs, my bra size is up 2 sizes, my pants size went from 0/1 to 6/7 and I'm miserable. I am now 140 lbs, 5"9, 16 years old.
    I am currently taking celexa (weening off of it, no weight loss) but I have been taking it for 4 years. I only started birth control a few months ago, so medicine does not seem to be the issue. I have had blood work done, my thyroid and everything is fine. I eat incredibly healthy, and I'm a runner. I mean c'mon. I have no clue what's going on. Sure, my weight is fine now, but if this continues it won't be. I'm out of guesses and my doctor has no clue.
    Any help, suggestions, or attempts to help will be wonderful. I'm just at a loss, thank you so much!

    Part of this may be explained by the use of hormone containing birth control, although often most of this is from fluid gains:
