To diagnose bulimia, different criteria, factors and causes must be taken into account.
The main sings of bulimia are:
- The consumption of a large amount of food within a short time.
- The inability to stop or control own food intake.
It is quite difficult to assess objectively the amount of consumed food to diagnose bulimia. The thing is that many people need much more food and drinks to keep a good health than the others do. Therefore, overeating symptoms must be assessed for each clinical case individually.
It should be noted that soon after overeating, a person provokes vomiting, which is an undeniable symptom or sign of bulimia nervosa.
It is no doubt that overeating and further vomit stimulation are an eating disorder. However, this type of behavioral disorder is not quite typical for people with bulimia nervosa.
To diagnose bulimia nervosa, it is necessary to consider both the amount and speed of consumption of food, as well as the environment in which the food is consumed. When person eats a great amount of food at the party, after a nourishing meal, this food intake may indicate bulimia nervosa. Moreover, periodic snacking throughout a day cannot be considered overeating episodes.
Three main conditional in the diagnosis of bulimia nervosa are:
- Several episodes of overeating within “limited time interval”.
- Consumption of more than 1 000 kcal within one overeating episode.
