What is anorexia? Symptoms, causes, treatments and help
Key points:
- Eating disorders vary and can consist of other underlying conditions recognised by the Diagnostic and Statistical Manual of Mental Disorders, fifth edition
- People may experience anorexia as a result of body dysmorphia, anxiety disorders such as post-traumatic stress disorder and depression or autism spectrum disorder
- Telling someone who has issues concerning diet or appetite that they need to eat more or less does not encourage them to do so, but it can, in fact, encourage them to continue their existing habits — you may need to seek professional advice
This edition of Disability Support Guide highlights the symptoms, causes and support options available for people living with anorexia. Anorexia nervosa is characterised by an aversion to eating, a perception of low body weight as an achievement and a fear of feeling ‘lesser’ through gaining weight. The etymology or ‘original source of terminology’ for the condition stems from the Greek phrase for ‘nervous absence of appetite.’
If you or a loved one is experiencing an eating disorder, it may present as being incredibly focused on food, despite their physical condition and restricted diet. Speaking disparagingly about a person with anorexia nervosa may enable their self-worth to be fully realised through the negative outcomes on their body.
Symptoms of anorexia nervosa
Symptoms of anorexia nervosa are separate from other disorders or conditions that may impact diet, such as:
Autism Spectrum Disorder
People with autism spectrum disorder, also known as ASD, may feel that certain foods are uncomfortable, with many people who have texture or taste preferences called ‘picky eaters,’ preferring foods which they are habitually familiar with.
Anxiety disorders
Anxiety disorders may play a role in diet and appetite disorders, as the possibility of eating in front of someone may bring to mind traumatic memories of bullying, body-shaming or social anxiety. For people who have overcome an eating disorder, the prospect of eating in front of another person may still be difficult.
Outside of other potential comorbid conditions, anorexia nervosa symptoms include:
- low body weight or being underweight;
- a consistently diminished appetite;
- irregular or abnormal menstruation with possible ‘spotting’ (in females);
- dizziness;
- delayed puberty or growth (in adolescents);
- low body temperature;
- anxiety or depression related to physical self-perception; and
- bulimia or other plans for eating without weight gain.
Probable causes of anorexia nervosa
Similar to obsessive-compulsive personality disorder, patterns of self-critique and perfectionism may be hereditary and life-long, although causes of anorexia nervosa are likely to be developed as a result of cultural or social pressure and unattainable physical ideals.
Research highlights the respective gender prevalence in anorexia nervosa, with women1.75 to three times as likely to develop the condition, which is thought to be a result of pressure placed on women, specifically.
However,recent findings suggest that men, particularly those involved in gym culture and immersed in social circles which emphasise weight-lifting, are increasingly likely to develop eating patterns associated with or that could contribute to a disorder.
Adverse outcomes
Ultimately, people who live with an eating disorder that restricts or encourages the mental suppression of physical requirements are at severe risk. Potential outcomes of anorexia nervosa may be fatal or may facilitate the onset of other conditions which pose a fatal risk to the human body, as a result of poor diet and nutrition and biological degeneration.
In addition, adverse side-effects of starving oneself may accelerate symptoms associated with anaemia, muscle loss, cardiovascular health, organ failure and hormone balance issues.
Support for people experiencing anorexia nervosa
Although it can be difficult to recognise a mental disability with severe psychosocial consequences that may inhibit day-to-day life or hasten life expectancy, physical perfectionism is immaterial as soon as it supercedes national health guidelines regarding body mass index, also known as BMI.
No one should have to live in fear of feeling unhappy with the healthiest version of themselves. If you or someone you know is experiencing anorexia nervosa, please refer to the following resources:
