During my first (very serious) gastroparesis flare I lost 90-100lbs. I’ve only been able to gain back like 20 lbs max. Only 10 is ever permanent. (It yo-yos cause I don’t try to gain or lose one way or another). I’d keep some fav staple pieces as a “just in case” if it was recent but there’s no point in wearing clothes that don’t fit. You’ll feel better wearing clothes that fit you and make you look good!
I had a bad gastroparesis plus colitis flare last year, and I lost about 20 lbs (which is a lot for me bc I was already slowly losing weight). Then a few months ago I lost another 10 in a flare. The most I seem to be able to gain back is about 5-6lbs. I’m just tired of pants that don’t fit clogging up my drawers
