Welcome aboard, probably the last place you figured you'd be or that you had never imagined you'd be here.
I'm like you, just recently, my tum started getting flabby and my weight shot up out of the blue. I blamed it on being married

Not that I'd give that up
I was first diagnosed with Hypothyroidism and not just Hypothyroidism, but with Hashimoto's Thyroiditis and my dermatologist said something about the possibility of PCOS. Sure enough, my endo did blood work and i'm on the high side of normal and have started taking 50 mcgs of Spironolactone twice daily. It's helped with the acne and my Synthroid for my Thyroid has helped with weight and feeling better overall.
Everyone here has been very helpful and will lend an ear or a shoulder. You're in good hands here.
