Eating
disorders closely related to obesity are binge-eating disorder and bulimia
nervosa.
Typical of
binge-eating disorder is uncontrolled, fast eating of large amounts of food
without feeling hungry. Diagnosis requires at least one eating attack per week
over 3 months. Eating attacks are also typical of bulimia nervosa, which,
unlike binge-eating disorders, includes subsequent vomiting, the consumption of
laxatives or arbitrary periods of hunger.
The binge
eating disorder occurs in the general population with a frequency of 1 - 3 %,
but in the obese collective with up to 50 %. In contrast to anorexia and
bulimia, binge eating disorder occurs in about 30% of men. Studies have shown
that 33% of all patients with bulimia and 42% of all patients with binge-eating
disorders are obese at the same time.
Other
eating disorders that are related to the development of obesity:
- night-eating syndrome, where large amounts of food are consumed in the evening or at night,
- sweet-eating syndrome, which is characterised by the consumption of predominantly sweet foods,
- grazing with frequent consumption of small amounts of food between main meals.
