What you have described in face is bulimia. If you are forcing yourself to throw up, or using laxitives, in order to remove food from your body, that is concitered bulimia. About your tingling in your hands and feet, you are right I am a certified nurses aid, and that tingling sinsation is probably due to blood presure issues because of the purging. You said you stay well hyderated, but if your purging that many times a day what you put in is probably coming right back out, there four your blood pressure is droping. Even if it is over 120/80, that does not mean you have a health blood pressure, everyone is different. I think it would be a good idea to call your doctor, because this is more than likely related. Im also not sure if your aware of it or not, but the only reason people loose weight through bolemia, is because your body is loosing water, and the energy you spend purging. When you eat the food, as soon as your swallow it, you have put the calories in, throwing the food up really isnt doing much for you but burn at your asophigus and teeth. That is a myth when people say once you put all the calories in you can get them all right back out. You would defiantly do better by just eating the stuff and since your already absorbing the calories rather you purge or not, just let it stay in your stomach while the vitimins and minerals obsorbe too, and exercise rather than purge. Your complection will look better too!
