An Iron Deficiency Made Selena Gomez Sick?

This is why pop star and actress Selena Gomez was rushed to the hospital:
Asked by reporters for the cause of her hospitalization, she said, "I was just very malnourished, so I was low on iron and exhausted."

Showing no signs of those health problems, an energetic Gomez performed "Who Says" and "A Year Without Rain" and bantered with the crowd, telling the fans, "I do feel better!"
Doesn't that sound awful? How does a healthy young woman end up malnourished unless she is paying far too much attention to her weight and physical appearance?  This is why it is so dangerous to expect people to be ridiculously thin and petite:
A Pre-Raphaelite's ideal woman was very different from Miss Joan Hunter Dunn, who died last week. She was John Betjeman's muse, a forceful young female with the figure of a school tennis champion. She was lithe and athletic - “the speed of a swallow: the grace of a boy” - whereas women who inspired Tennyson or the Pre-Raphaelite painters tended to be aesthetic, passive and wan.
At times over the past 200 years it has been fashionable to be pale, anaemic, wasted and apparently fragile. Doctors' practices, other than those of specialist haematologists where vigilance in searching for undiagnosed anaemia is likely to be rewarded, are usually those catering for children, young women, the elderly, food faddists, or they may have an interest in cardiology and chest medicine. A large number of patients with anaemia first notice a shortness of breath, palpitations and persistent tiredness and are referred to cardiologists or respiratory physicians.
Anaemia is much more common than suspected. Often anaemia leaves clues far more subtle than a pale face and/or breathlessness brought on by climbing the stairs. To make the diagnosis more difficult, excessive fatigue from iron deficiency can worry a patient before anaemia is detectable because of a low haemoglobin level, the standard blood test. To make certain that a patient is not iron-deficient, estimates of serum ferritin, or total iron-binding capacity and serum iron, are needed. The most common cause of anaemia is iron deficiency, whether caused by a vegetarian diet deficient in the mineral, or by an excessive, but sometimes hidden, loss of blood.
A speciality that is not often associated with anaemic patients is dermatology. A dermatologist recently lamented that he was seeing too many patients with iron-deficiency anaemia, which had caused poor-quality skin, thinning lacklustre hair, flaky nails and, in women, a prolonged interval between periods and a longer premenstrual syndrome
It's time to start a new fad, one that says that it's okay to have a little weight on you from time to time.
