A seventeen-year old girl who wanted desperately to get into shape before her upcoming farewell party in school. She practically starved herself, surviving only on fresh fruit and lime juice, and exercised vigorously for three long months. Eventually she managed to lose a visible 12 kg, and there was no end to the compliments she got at the party. Only when she passed out in the school corridor almost four months after the farewell, did her parents and friends realise she had secretly kept up her strict diet plan for way too long.She was diagnosed and later treated for anorexia – an eating disorder that is characterised by extreme loss of appetite for food and an obsessive fear of weight gain. This is a case study of a patient who came to me for help 10 years back. These cases were few and far between then.But today this is not an uncommon story any more. Cases of anorexia have increased exponentially lately.What is Anorexia Nervosa?With anorexia what starts as an ordinary intention of a slimmer body soon becomes an obsession to pursue the impossible because people with this disorder continue to think they’re fat even when they are bone-thin.In fact, denial and preoccupation with food and weight are the two most important signs of trouble.The problem here is that many life-threatening issues – both emotional and physical – can arise if anorexia becomes an entrenched life pattern. The sooner this eating disorder is recognized and treated, the easier it is for the person to recover, and the later it gets, the longer the person will have to struggle before he/she can turn matters around. And in some cases this could mean a whole lifetime.How Anorexia Affects One’s HealthIn the cycle of self-starvation, the body is denied the essential nutrients it needs to function normally. Thus, the body is forced to slow down all of its processes to conserve energy that results in serious medical consequences – in prolonged cases, even death. Common symptoms are:Abnormally slow heart rate and low blood pressure, which means that the heart muscle is changing. The risk for heart failure rises as the heart rate and blood pressure levels sink lower and lowerReduction of bone density (osteoporosis), which results in dry, brittle bonesMuscle loss and weaknessChanges in or loss of menstrual cycleSevere dehydration, which can result in kidney failureFainting, fatigue, and overall weaknessDry hair and skinGrowth of a downy layer of hair called lanugo all over the body, including the face, in an effort to keep the body warmMemory loss and lack of concentrationApp-Based Therapy May Treat Anorexia, Finds a New StudyThe Warning Signs of AnorexiaDetecting anorexia can be hard because what seems like a healthy desire to experiment may actually be something very seriously abnormal.
