Types of Eating Disorders

There are several types of eating disorders, and a lot of people are suffering from it. Some may cause weight gain while some may cause abrupt weight loss. This case is very rampant among teens as they get very much conscious about their looks, so they tend to eat lesser.

On the other hand, some get emotionally disturbed during the stage of adolescence which may eventually lead them to overeat. Eating disorders pertain to a state of abnormal eating habits which may refer to either insufficient or excessive food intake. Anorexia, bulimia, and binge are the three (3) common eating disorders in the United States. Based on records there are 5-10 million of women in the US suffering from this disorder while there are only 1million cases among men. Although cases were eating disorders continually increases all over the world, evidence has shown that it is women who have the higher risk of developing them.

Causes of eating disorders are not fully determined. But there have been many pieces of evidence that may lead to a conclusion on its causes. One study has shown that women who have an ADHD problem are more prone to developing eating disorders; while some studies have shown that emotionally challenged people are most like to suffer from eating disorders.

To make it quite defined, eating disorders may be caused by biological factors, psychological factors, environmental factors, some of the personality traits, social indicators, etc.

Some of the Biological abnormalities that may lead to eating disorders are:

  • Genetics. One of the possible causes may be due to genetic predisposition which may have resulted from Mendelian inheritance.
  • Through the mechanisms of Epigenetics.
  • Biochemical factors. Abnormalities in the interaction of the different glands.
  • Development of hormones such as leptin & ghrelin.
  • Overactive Immune system.

Psychological factors may include the following:

  1. Severe depression.
  2. Being alcoholic.
  3. Other Anxiety disorders.
  4. Obsessive-compulsive syndrome.
  5. ADHD or Attention-deficit Hyperactivity Disorder.

Anorexia Nervosa

Anorexia nervosa is a type of eating disorder which is perfectly defined by these three (3) main descriptions:

  1. People suffering from this eating disorder refuse to maintain a healthy BMI.
  2. Anorexia nervosa brings an intense fear of weight gain.
  3. The worst indication of having anorexia nervosa is the distorted body sculpture.

Anorexia is more than just about food and weight. It is more on the emotion that is affected. The food and weight factors are just unhealthy symptoms of being depressed, lonely, and insecure and having the pressure to be perfect at all times.

Bulimia Nervosa

Is a eating disorder described by refusing to eat foods for quite some time but is followed by a big splurge of food bringing a guilt feeling or low self-esteem. After the food pig-out, the most common defense from guilt is vomiting. This type of disorder is more common in women than men.

Binge Eating Disorder

Binge eating disorder or BED is an eating disorder that is very widespread among people craving for a huge weight loss. Binge is not yet defined as a separate eating disorder however it has already been characterized and treated as such as it was described to be a night eating disorder by Albert Stunkard, a psychiatrist, and researcher, in 1959.

Binge is somehow similar to compulsive eating disorder. They tend to eat just a little in the morning, but not to the point of fasting, and then give in to their cravings at night time. Unlike bulimics who feels guilty after splurging on foods, binge patients don’t do anything to burn what they have overeaten. Binge eating disorder occurs in people who are overweight and obese people.
