My sister is 5 foot 10 and is 24 years old and weighs 110 pounds, a month ago she weighed 125 pounds, she went to the doc and they said she had gastronitis and an ulcer, they havent done much about it, but i feel like it may be something else, she has a hurt stomach all the time, she can hardly eat, and she looks almost like a skeleton, just a little curious what another doctors prospective of this would be, i feel like she needs a second opinion on this she keeps dropping so much weight, she lost 5 pounds in less then a week. Please tell me what you think this could be and what she should do?
