What is an Eating Disorder ?
Eating Disorders describe illnesses that are characterized by irregular eating habits and severe distress or concern about body weight or shape. Eating disturbances may include inadequate or excessive food intake which can ultimately damage an individual’s well-being. The most common forms of eating disorders include Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorder and affect both females and males. Eating disorders can develop during any stage in life but typically appear during the teen years or young adulthood. Classified as a medical illness, appropriate treatment can be highly effectual for many of the specific types of eating disorders. Although these conditions are treatable, the symptoms and consequences can be detrimental and deadly if not addressed. Eating disorders commonly coexist with other conditions, such as anxiety disorders, substance abuse, or depression.
Types of Eating Disorders
The three most common types of Eating Disorders are as follows:
- Anorexia Nervosa -The male or female suffering from anorexia nervosa will typically have an obsessive fear of gaining weight, refusal to maintain a healthy body weight, and an unrealistic perception of body image. Many people with anorexia nervosa will fiercely limit the quantity of food they consume and view themselves as overweight, even when they are clearly underweight. Anorexia can have damaging health effects, such as brain damage, multi-organ failure, bone loss, heart difficulties, and infertility. The risk of death is highest in individuals with this disease.
- Bulimia Nervosa Nervosa -This eating disorder is characterized by repeated binge eating followed by behaviors that compensate for the overeating, such as forced vomiting, excessive exercise, or extreme use of laxatives or diuretics. Men and women who suffer with Bulimia may fear weight gain and feel severely unhappy with their body size and shape. The binge-eating and purging cycle is typically done in secret, creating feelings of shame, guilt, and lack of control. Bulimia can have injuring effects, such as gastrointestinal problems, severe hydration, and heart difficulties resulting from an electrolyte imbalance.
- Binge Eating Disorder- Individuals who suffer from Binge Eating Disorder will frequently lose control over his or her eating. Different from bulimia nervosa however, episodes of binge-eating are not followed by compensatory behaviors, such as purging, fasting, or excessive exercise. Because of this, many people suffering with binge-eating disorder may be obese and at an increased risk of developing other conditions, such as cardiovascular disease. Men and women who struggle with this disorder may also experience intense feelings of guilt, distress, and embarrassment related to their binge-eating, which could influence further progression of the eating disorder.
