Short Term and Long Term Side Effects of Anorexia

Anorexia is typically thought of as a disease that affects younger women and teens, but individuals of any age or sex can suffer from this devastating eating disorder. Anorexia nervosa can turn deadly if not treated properly. Before continuing further, if you are suffering from anorexia nervosa, contact a licensed professional as soon as possible.
In this post we will review both the short-term side effects of anorexia and the long-term side effects of anorexia. If you’re looking for more information about anorexia nervosa treatment, read our post here or read our post about foods I recommend for anorexia refeeding.
What is Anorexia Nervosa?
Before we get into the side effects of anorexia, let’s define what anorexia nervosa is. Anorexia nervosa, often referred to as simply anorexia, is an eating disorder characterized by extremely low body weight, a strong fear of gaining weight, and a distorted view of weight. A person suffering from anorexia nervosa strives to control their weight and their body shape, often using extreme ways to accomplish their goals that often significantly interfere with their daily life.
A person suffering from anorexia will severely limit their caloric intake, induce vomiting to limit how much calories they’ve consumed, or misuse laxatives, diet pills/aids, and/or diuretics or enemas.
Criteria for Diagnosing Anorexia Nervosa
According to DSM-5, or the Diagnostic and Statistical Manual of Mental Health Disorders, 5th Edition, a person must meet all of the following criteria to be diagnosed with anorexia nervosa:
- Restriction of food intake leading to a loss in weight or a failure to gain weight, which results in a significantly low body weight expected for someone’s age, sex, and height
- Fear of becoming overweight or gaining weight
- Having a distorted view of themselves and their condition
Now that we’ve reviewed the criteria for diagnosing anorexia nervosa, let’s jump into some general side effects of anorexia.
