In 2011, Selena Gomez was taken to the hospital where she was found to be malnourished, exhausted and she had an iron deficiency anemia. Made popular for her boyfriend Justin Bieber and her hit show The Wizards of Waverly Place, her iron deficiency made her so tired she couldn't function. Her hospitalization incident was right after an appearance on The Tonight Show where afterward she was unable to function. After a couple of rough years, Gomez learned that she has Lupus. There is no cure for the auto-immune condition Lupus, but the iron deficiency is just one of the hallmarks that come along with the disease.
