I am 19 years old and I am 5' 2 and weigh 87 pounds. It is nasty to me! I have done everything I can and I do eat a lot! I also have a heart problem. If I am standing up too long or even vacuming the house. My hearts starts beating fast, I get dissy, and almost black out. Also, I have a heartmurmor. For everything I do, I just can't seem to gain weight. My mom seems to think that it has something to do with my heart. I need some sort of an answer to why I can't gain any weight or how I CAN gain weight. I have been fighting this problem for 3 years now and it is beginning to scare me! Someone please give me an answer or an idea. I would apreciate it! Thank you!

Have you discussed this with your dr yet?
