The word binge eating should not be unfamiliar to anyone, when you meet a good food to your taste or when you are in a bad mood, you will inevitably indulge yourself and gobble it up. As long as the usual diet and lifestyle habits are normal, occasional overeating will not have much impact on the body, but if you let yourself suffer from bulimia, it will be more trouble. Bulimia is an uncontrollable recurrent binge eating disorder and a psychiatric disorder that is very likely to lead to obesity and was added to the Diagnostic and Statistical Manual of Mental Disorders as early as 2013. People with this disorder often consume large amounts of food and continue to eat even when they feel full, basically losing control of their eating. And after eating, they do not get rid of the food through vomiting and laxatives, as bulimics do, so they are very likely to experience explosive weight gain. Under the influence of this diet and weight gain, bulimic patients suffer from heart disease, type 2 diabetes, acute gastroenteritis and many other diseases. In addition, according to statistics, many people with bulimia also suffer from psychological disorders such as depression and anxiety at the same time, and these disorders also interact with physical disorders such as obesity to aggravate the condition. Bulimia is a serious psychological disorder that not only affects their normal life, but also has an impact on the treatment of obesity and other complications caused by bulimia, and requires early psychological treatment. Patients with a history of obesity need to be followed up by a psychiatrist for a long time to provide the necessary psychological guidance after the weight reduction and metabolic surgery.
