Bulimia nervosa is a potentially life-threatening eating disorder. Read about the symptoms and treatment options.
Bulimia nervosa is a serious eating disorder characterised by frequent episodes of binge eating followed by extreme purgative efforts to avoid gaining weight, often by vomiting or exercising to excess.
Bulimia nervosa can be diagnosed when a person eats an excessive quantity of food in a single sitting, and invokes purgative behaviour, at least twice a week for three months.
A subtype of bulimia, called non-purgative bulimia nervosa, excludes the use of purgation, but most of the other signs, symptoms and consequences apply.
Bulimia nervosa and anorexia nervosa are the two main eating disorders. They are similar in the sense that both involve weight control and purgation tactics, as well as the paradox of binge eating. However, there are major differences between them:
Both disorders are more intense than normal dieting efforts and both lead to serious health problems. Although bulimics may not look emaciated, their behaviour depletes proteins, vitamins, enzymes, and other vital resources needed to maintain their health.
Some people with anorexia nervosa may develop obsessive binge eating, on top of their obsession with starvation. When that happens they will not be reclassified as bulimic, as the classification of anorexia supersedes that of bulimia.
Risk factors for acquiring bulimia nervosa include:
Persons with bulimia nervosa may not have an emaciated appearance, because they are not obsessed with becoming thin – they are only obsessed with keeping their weight normal. This makes it difficult for outsiders to identify the presence of bulimia. However, there are certain signs indicating the disorder, including these:
Comorbid disorders are often encountered in bulimic patients. These vary from undetected, pre-existing mental disorders, to substance use disorder (alcohol and drug abuse).Treatment Methods for Bulimia Nervosa
The following methods, or combinations of them, are available:
Medical Care: Ensures that physical illnesses are cured and may include prescriptions for medications required for physical and mental ailments. Prescribed medications are usually for short-term use only.
Psychotherapy: Psychological treatment, usually a combination of cognitive and behavioural therapies. Available on an inpatient or outpatient basis. Treatment in a residential rehabilitation centre is recommended, as it provides ideal ambience and facilities for recovery.
Dietary plans: Changes in types of food and upheavals in eating patterns can cause complications. A professionally designed recovery diet is important. Dynamic residential rehabilitation centres usually prepare prescribed dietary meals for patients.
Eating disorder treatment is determined by the type of disorder and the symptoms you are experiencing. It typically includes a combination of psychological counselling or psychotherapy, nutrition instruction, medical monitoring, and, in some cases, medication.
Other health issues caused by an eating disorder must also be addressed as part of eating disorder therapy, as they can be severe or even fatal if left untreated for too long. If your eating disorder does not improve with conventional treatment or poses a health risk, you may require hospitalization or another type of inpatient program.
A systematic approach to eating disorder treatment can assist you in managing symptoms, regaining a healthy weight, and maintaining your physical and emotional health.
