My younger sister is almost 13 years old and weighs 180 lbs but is 5'6. I'm 5'2 and weigh 160 lbs, but her belly makes her look pregnant and I wear a size 12 and our weight difference is only 20 lbs but she is also 4 inches taller. Also, both her biological parents are tall and thin so genetically she should be too (tall she is but thin not). I was thinking about it this morning and started to wonder if maybe her stomach wasn't fat but some sort of disorder or disease and I've tried WebMD and I've looked on Wrong Diagnosis and I can't find any kind of diseases or disorders that might fit her... problem. If anyone has any information or similar problems I would be very greatful for your help.Reply Follow This Thread Stop Following This Thread Flag this Discussion
