Eating disorder is a mental disorder, in which people have abnormal eating habits that can affect a person’s physical and mental health.
Eating disorder has many different symptoms.
One symptom is binge eating, in which people eat a large amount of food in a very short period of time. The food amount is much more than the body needs.
Another symptom is anorexia nervosa, in which people eat very little and therefore have a very low body weight.
A third symptom is bulimia nervosa. People with this disorder tend to eat a lot of food first and then compulsively get rid of the food they just eat.
Other eating disorder symptoms include eating non-food items, lacking interest in food and so on.
Researchers have found that eating disorder is linked to other mental problems, such as anxiety, depression and drug abuse.
Although obesity is not related to eating disorder, recent studies do find that body weight change can be associated with eating disorder risk in some people.
One study recently published in the International Journal of Eating Disorder shows that too much weight increase and weight decrease are linked to eating disorder in women who are 50 years old and older.
In the study, researchers from the USA, Australia and Sweden examined weight suppression and weight elevation in older women.
Weight suppression means the current body weight is lower than the highest past non-pregnant body weight.
Weight elevation means the current body weight is higher than the highest past non-pregnant body weight.
1776 women were examined from local communities. They completed online survey about their eating habits.
The researchers measured the women’s body weight, BMI, and health conditions.
The team found that women that were higher on weight suppression and weight elevation were more likely to try to lose weight and have a diet in the past five years.
Women whose current body weight was much lower than the past were more likely to experience binge eating, check their weight frequently, and become too sensitive about their body shape.
On the other hand, women whose current weight was higher than the past were more likely to report negative feelings about dieting and eating.
Interestingly, both groups tended to skip meals over the lifetime.
The researchers conclude the body weight change may play a big role in women’s development of eating disorders and that future studies should pay more attention to these risk factors.
