Anorexia nervosa

The most well known eating disorder, thanks to movies and novels. Anorexia nervosa translates to loss of appetite, a misnomer in itself. It involves, self induced starvation, a desire for thinness and the presence of medical complications resulting from a grossly inadeqate diet. Thinness is sometimes considered the sole source of self esteem. With an age of onset in the late teens, it has the propensity to cause long standing damage to a child's development. A BMI of lesser than 17 in the presence of above features indicates anorexia.

Anorexia nervosa can cause long standing morbidity and a number of physical complications if not identified and treated appropriately. Effective treatment modalities are available, ranging from psychotherapy, behavioral interventions  and medications. 



Bulemia nervosa

Bulemia translates to ox-hunger and for some it may be considered a lesser form of anorexia. Despite the underlying misonceptions about thinness, patients with bulemia do not reach dangerously low body weights. They also indulge is impulsive binge eating and compensatory purging or excessive exercise. Impulsivity, substance abuse and behavioral disturbances are commoner than in comparison to the general population. People with bulemia are less likely to seek help when compared to those with anorexia. Binges and purges often occur in secret further delaying help seeking. It becomes essential for parents and teachers to be able to identify bulemia. Like in most mental illnesses, earlier the intervention better the prognosis.


Binge eating disorder

People suffering from binge eating disorder often eat an abnormally large amout of food over a relatively short period of time. Unlike in bulemia, there is an absence of compensatory behaviour ( purging and  exercise), leading to a gain in weight. 50-75 percent of those with a BMI of over 40 fulfil criteria for the diagnosis of binge eating disorder. There is usually a feeling of loss of control during these binge episodes. Binging is often associated with an extroverted and impulsive personality types. All of us know the dangers of obesity and its consequences. 

Certain behavioural methods, drugs that reduce cravings and thought restructuring have been found to be effective in managing binge eating and obesity.

Other than its primary fuction of providing nutrition, food has a much deeper, emotional connect. When a function as basic as eating becomes distrupted, the consequences (both physical and mental) that may ensue have no limits. Eating disorders are commonly associated with depression, anxiety, sleep disturbances, diabetes, heart disease, thyroid disease and menstrual abnormalities. Most people do not seek help due to a complete lack of awarenes about mental illnesses. One should always remember that, help and treatment are  available for those who seek it. Fear and guilt should never prevent treatment seeking, Break the stigma, help others seek help !
