This may be the wrong section but I wasn't sure where to post it. My wife has struggled her whole life to put on weight no matter what she does. We've tried increasing her calorie intake by shakes, making her eat until she is about to throw up all etc with no help. She may put on a pound or two but the next week she is right back down where she was. She is 30 years old and only weighs 93-95 lbs sitting at 12% bodyfat (which isn't healthy obviously). We are wondering if this could possibly be a hormone issue. We have an appointment to meet with a doctor and see what they say but figured I'd hope on here and ask if anyone knows anything about this or has any ideas of something she could take to possibly help her out.

Some symptoms she has is extremely painful menstrual cramps (kind of irregular) thinning hair, low sex drive, obviously weight and body fat issues, always exhausted, but doesn't sleep well overnight often.

Any advice or ideas are welcomed and appreciated.
