1)Anorexia: If you got a really really bad sunburn when you were young, it can have triggered a condition known as "HYPERCALCEMIA"...Too much calcium in your body caused by the excess of Vitamin D...Doctors have to identify hypercalcemia immediately, then in hospital, drain the body of calcium...With liquids , chelation-it is complicated...Undiagnosed, Hypercalcemia becomes CHRONIC ANOREXIA, which can be fatal...If you know an anorexic, know this, it is NOT in their head...Ask them if they ever had a really bad sunburn just before they became anorexic...You will surprised...Cure???: Once you have identified that your friend with anorexia is suffering from chronic hypercalcemia, at least you now have a start...What you then have to figure out is how to help your friend remove years of calcium from her body...Yes, it may be counter-intuitive to say that your so skinny friend is hypercalcemic- but push forward...My suggestion? The only over the counter thing that I know on the market that easily removes calcium from the body is nicotine...So, I suggest, your anorexic friend start chewing a little bit of nicorette gum daily...For a long time, while the nicotine removes the excess calcium from your friend's body...Remember, it is counter-intuitive- meaning, that encouraging nicotine use in an already skinny person seems ridiculous- since we all know smoking makes you thinner...But it is not fat we are attacking, it is calcium...We are trying to correct chronic hypercalcemia...We are trying to Induce osteoperosis actually...Sounds crazy? Well, alot of new ideas are...Just tell your anorexic friend, she is NOT crazy! Hypercalcemia is a real disease...
