Understanding Anorexia

Learn about anorexia treatment

Anorexia nervosa is a severe mental health disorder that is characterized by an obsession with weight and the extreme restriction of food intake, which can lead to dangerous weight loss. The desire to curb and/or stop eating comes from the fear and anxiety of gaining weight or getting fat. Individuals with this mental illness often take extreme measures to stop weight gain, leading to serious health problems. Using laxatives, diuretics, and/or enemas is common for those who struggle with anorexia, as is carrying out ritualistic behaviors when it comes to preparing and eating food. Exercising to excess is also another behavior that those will anorexia might display. The fear or anxiety one experiences can cause a variety of other severe mental and physical health risks that could be deadly if not treated.

There are two forms of anorexia nervosa that an individual can be diagnosed with. The most common form of anorexia, which is the restricting type, includes fasting, dieting, and excessive exercising. The other form of anorexia is known as binge-eating/purging, which includes overeating followed up by self-induced vomiting to remove food from an individual’s body. Both of these forms of anorexia include distorted and intrusive perceptions of one’s body image. Many times, those with this type of disorder view food as dangerous, and any kind of encouragement to eat from others is considered threatening to one’s goal of losing weight. Thankfully, treatment is available to those who battle with anorexia. By intertwining effective treatment and appropriate methods, those with anorexia nervosa can learn how to live happy, healthy lives that are no longer impacted by this disorder.


Anorexia statistics

Roughly 24 million people suffer from an eating disorder, including anorexia nervosa. Among adolescents and young adults, the third most common, chronic, diagnosed illness is anorexia nervosa, which is most common among individuals between the ages of 12 and 26. About 0.5% of the female population is affected by anorexia nervosa. This mental health condition is most common among females, with about 90% of anorexia cases involving girls and women, but individuals of all genders do suffer from this disease. This mental health condition has an incredibly high mortality rate and can add to an individual’s chances of developing self-harming behaviors, suicide attempts, and suicidal ideations.

Causes and Risk Factors

Causes and risk factors for anorexia

Experts in the field of eating disorders agree that a variety of contributing factors can add to one’s development of anorexia nervosa. Consider the following when trying to understand the origins of one’s eating disorder:

Genetic: Those who have a close relative, such as a sibling or a parent, with an eating disorder, bipolar disorder, or depressive disorder are at a greater risk for showing signs and symptoms connected to anorexia nervosa. Because of this tie, it can be concluded that one’s genetic background can serve as a factor in one’s development of anorexia. In addition, studies have shown that the rates of prevalence for this specific mental health condition are greater in identical twins than in fraternal twins.

Environmental: Experts believe that one’s culture and environment can play a major role in the importance of being thin, which can in turn contribute to the development of anorexia nervosa. Specific occupations, including those in sports and the fashion industry, can also lead to a greater risk in developing this condition based on the focus on one’s physical appearance. Additionally, those who struggle with chronic stress, abuse, trauma, and neglect are said to be at a greater risk for developing this disorder, as restricting food can provide them with the control that they desire but are lacking in other areas of their lives. Lastly, being teased about one’s weight during adolescence can also serve as a factor in the development of anorexia.

Risk Factors:

  • Family history of eating disorders or other mental illnesses
  • Preexisting mental illness or illnesses
  • Exposure to chronic stress / trauma / abuse/ neglect
  • Being the victim of bullying
  • Being in an environment or part of a culture that strongly values thinness
