The Psychological Effects of Anorexia Nervosa

Depression, Anxiety, and Other Mood Disorders

Anorexia nervosa can have a wide range of psychological effects on an individual. The most prevalent mental disorder types are mood disorders like depression and anxiety[2]. Among them, the most common type is Depression, with a prevalence rate of approximately 40–45%, followed by a range of anxiety disorders with a prevalence rate of 60%[2].

Personality Disorders

Research indicates that individuals who suffer from anorexia nervosa are also more likely to have personality disorders [2]. The most common type of personality disorder is obsessive-compulsive disorder, followed by borderline personality disorder[12].

Self-Injury, Suicidal Thoughts, or Suicidal Attempts

Studies show that suicidal attempts in AN patients are common, with estimated ranges of 3.0% to 29.7%[13]. Major depression is the most common psychiatric comorbidity associated with suicidal attempts, followed by borderline personality disorder and substance abuse [14] .

Alcohol and Substance Misuse

Studies show that patients with binge-eating/purging anorexia nervosa may misuse alcohol and substances although they are afraid of gaining weight, while patients with restricting anorexia nervosa may not use substances because of their strict dieting regimens and control over food intake[15]. The misuse of alcohol and substances also increases the risk of suicidal behavior in AN patients, as substance abuse can lead to impaired judgment and impulsivity[17].

The Physical Effects of Anorexia Nervosa

Bone Health

Long-term denial of food intake affects many physiological systems, including the bones. Anorexia nervosa increases the risk of low bone mineral density (BMD) [1], osteopenia (loss of bone calcium), and osteoporosis (a progressive loss of bone density), which are conditions that can lead to fractures and deformities of the spine [2].

Cardiovascular System

Research reveals that 80% of patients with eating disorders suffer from cardiovascular complications[2]. Severe anorexia nervosa can lead to an irregular heartbeat, arrhythmia, abnormally low blood pressure, and a decreased heart rate[2]. It is also associated with an increased risk of heart failure, which can be life-threatening [3].

Nutritional Deficiencies

A person suffering from eating disorders usually has a poor diet and can develop several nutritional deficiencies; the most common deficiencies are zinc and Vitamin D, followed by copper, selenium, and vitamin B1 [4]. These vitamin deficiencies can lead to anemia, a weakened immune system, poor bone health, and can even interfere with the metabolism of essential fatty acids and carbohydrates [5].

Gastrointestinal System

This eating disorder can also cause significant damage to the gastrointestinal system. Anorexia Nervosa patients can suffer from gastrointestinal complications such as hypokalemia, hypomagnesemia, and hypocalcemia [2]. Refeeding to gain weight can cause further gastrointestinal problems, such as bloating, distention, and abdominal cramps[2].

Reproductive Health


Anorexia Nervosa can have serious effects on reproductive health. In women, the menstrual cycle can be disrupted or cease completely due to significantly low body weight[6]. Long-term reproductive health risks include infertility and pregnancy complications [6]. Further, the offspring of women with anorexia may be at a higher risk for malformations or low birth weight, as maternal undernutrition during pregnancy can affect the development of the fetus[6].


In men, anorexia can lead to sexual dysfunction as low testosterone levels, and depleted energy reserves can cause a lack of interest in sex or erectile dysfunction [7]. It can also cause decreased muscle mass, infertility, and an inability to gain weight caused by decreased metabolism and energy intake[7].

Strategies for Prevention and Recovery

Early detection and intervention can help individuals with anorexia nervosa to prevent further psychological and physical damage. Treatment for anorexia nervosa typically includes a combination of psychotherapy and medical interventions, depending on the severity of symptoms. Psychotherapeutic intervention includes [10];

In addition to psychotherapeutic treatments, nutritional counseling can help individuals struggling with disordered eating habits to make healthier food choices and ultimately return to a healthy weight[11].

In extreme cases, hospitalization or residential care may be necessary for individuals who are severely underweight and at risk of medical complications[9].

It is important to seek professional help if you or someone you know has signs or symptoms of anorexia. Proper treatment is necessary for a successful recovery and achieving a healthy lifestyle.


Can anorexia permanently damage your body?

Yes. In some cases, when the patient's weight can not be restored, anorexia can cause permanent damage to the body, such as weakened bones, malnutrition, and organ failure. However, with proper treatment and support, most people with anorexia can make a full recovery.

Does anorexia destroy the brain?

In extreme cases, yes. Anorexia can cause serious damage to the brain due to long-term malnutrition and dehydration. If left untreated, anorexia can cause permanent brain damage and even death. In most cases, however, with proper treatment and support, people with anorexia can make a full recovery.
