Bulimia Nervosa: Causes & Symptoms

By: Dr. Sonia Lal Gupta and Dr. Sameer Gupta

Not many people in today’s society are aware of the devastating reality of ‘eating disorders’. They are often perceived as being self-inflicted and attention seeking behavior. However, the reality of these disorders is much grimmer than one would anticipate. Eating Disorders are serious and complicated mental disorders that can be potentially life-threatening. In fact, it was found that more people die from eating disorders than from any other mental illness. One such dangerous eating disorder is ‘Bulimia nervosa’.

What is Bulimia nervosa?

Bulimia nervosa (generally referred as bulimia) is an eating disorder which is characterized by a vicious cycle of binging on food and purging. The person suffering from this illness often experience episodes of eating excess amounts of food followed by compensatory behavior like misusing laxatives, vomiting or exercising to excess, in order to prevent weight gain. This binge-and-purge cycle has a damaging effect on the digestive system and can result in life-threatening complications.

Causes:

There is a general misconception that bulimia and other eating disorders are limited to negative body image and desire to be thin. But this is not the case. There are several psychological and cultural factors or a combination of them that play important role in development of these disorders:

  • Anxiety & stress
  • Depression
  • Societal Pressure
  • History of abuse
  • Poor self-esteem
  • Genetic

Warning Signs and Symptoms:

A person suffering from Bulimia nervosa may or may not experience extreme change in body weight. Thus, Bulimia can often go undetected for a long period of time as you can’t tell whether a person has an eating disorder just by looking at their appearance.

An individual with Bulimia nervosa shows physical, psychological and behavioral symptoms:

  • Frequent weight fluctuations

  • Feeling that they can't control their eating behavior.

  • Misuse of laxatives, enemas, appetite suppressants or diuretics
  • Avoiding meals with other people and eating in secrecy
  • Self-harm
  • Alcohol and drug abuse
  • Excessive exercising
  • Alternating between overeating and fasting.
  • Anti-social behavior and mood changes.

Effects of Bulimia on body:

The constant pattern of eating and purging is destructive for the body. Bulimia nervosa not only has devastating effects on digestive system but also contributes to other health complications. Here are some severe health problems caused by this eating disorder:

  • Electrolyte imbalance leading to heartburns and heart failure
  • Tooth decay and inflammation of food pipe because of frequent vomiting
  • Gastric rupture

This is a serious condition and if someone you know suffers from Bulimia, they should get medical help right away.
