Anorexia nervosa, commonly referred to as anorexia, is a severe eating disorder that involves an obsessive fear of gaining weight, distorted body image, and severe calorie restriction. People with anorexia often have a distorted view of their bodies, believing they are overweight even when they are dangerously underweight. This condition can lead to serious health complications and even death. Those suffering from anorexia may engage in extreme behaviours such as excessive exercise, self-induced vomiting, and the misuse of laxatives or diuretics to control their weight. While the exact cause of anorexia is unknown, a combination of genetic, biological, psychological, and environmental factors is believed to contribute to its development.

What You'll Learn
Extreme calorie restriction
Anorexia nervosa is an eating disorder that involves severe calorie restriction and often a low body weight. People with anorexia nervosa have an intense fear of gaining weight and a distorted body image, seeing themselves as overweight even when they are dangerously underweight. They may also have an obsessive interest in food, calories, and dieting, and may feel a strong need to be in control of their eating habits.
In addition to severe food restriction, people with anorexia may also engage in excessive exercise to burn off any consumed calories and prevent weight gain. They may spend hours at the gym or doing other forms of cardio or intense physical activity, even when their bodies are weak from malnutrition. This extreme exercise can be a form of compulsion, providing a sense of control and an outlet for overwhelming emotions.
Another way that people with anorexia may restrict calories is by purging, or getting rid of food after it has been eaten. This can include self-induced vomiting, the misuse of laxatives or diuretics, or the use of enemas. Purging allows people with anorexia to consume food while still maintaining strict calorie restriction, as they can eliminate the calories before they are fully digested and absorbed by the body.
Finally, some people with anorexia may use appetite suppressants or diet pills to reduce their hunger and further restrict their calorie intake. These medications can help them stick to their extreme diets by making it easier to ignore their body's natural hunger signals. However, this practice can be dangerous and have serious health consequences.

Excessive exercising
Excessive exercise is a common feature of anorexia, with approximately 44.6% to 80% of anorexic individuals suffering from compulsive exercise behaviours. This compulsive exercise is driven by an intrinsic drive caused by the energy imbalance resulting from food restriction. It is important to note that excessive exercise in individuals with anorexia nervosa can be extremely dangerous and even life-threatening.
People with anorexia nervosa often have a very slow heartbeat. While this is also seen in athletes, a healthy heart can adjust and speed up when needed. However, the combination of a weakened heart and excessive exercise can strain the heart to its breaking point. The risk of overuse injuries is also heightened due to restricted meals, which may not provide the necessary nutrients for tissue repair. As a result, pulled muscles, sore tendons, and stretched ligaments may worsen with each workout.
Exercising excessively can deplete the body's stores of salts, which are needed for cell communication. This exacerbates the existing electrolyte imbalances that individuals with anorexia often have due to their restricted eating habits. Additionally, certain forms of exercise can put their frail bones at risk of fractures. Using weight machines, running on rough roads, and playing contact sports could result in broken bones.
Excessive exercise can also have a detrimental impact on an individual's mental health and social life. Research has shown that both social impairment and depression are common in people who exercise compulsively. This can lead to deepening isolation and a worsening of the eating disorder.
It is crucial for individuals struggling with excessive exercise and anorexia to seek professional support. Eating disorders are severe mental health disorders that can have life-threatening physical complications, especially when paired with compulsive exercise. Treatment plans involving doctors, nutritionists, and sports trainers are essential for addressing this complex condition.

Purging
The binge-eating/purging subtype of anorexia nervosa can lead to serious physical and mental health complications, including heart attack, osteoporosis, anxiety, and depression. It can also cause heart damage and increase the risk of death due to medical complications related to starvation, such as cardiac arrest or electrolyte imbalances.
Treatment for this subtype of anorexia nervosa may include nutritional rehabilitation, weight restoration, family therapy, CBT, medications, or a combination of these approaches. It is important to work with patients to heal their relationship with food and develop a peaceful relationship with it. This may involve providing nourishment and psychosocial support, as well as education on food portions, meal plating, and nutrition.
If you or someone you know is struggling with an eating disorder, help is available. Many organisations offer hotlines, texting services, and instant messaging with trained professionals. Additionally, interactive maps can help locate state-by-state treatment options for eating disorders.

Distorted body image
Anorexia nervosa is an eating disorder characterised by severe calorie restriction and a fear of gaining weight. It is associated with a distorted body image, which is a key symptom of the disorder. This distorted body image can lead to an intense fear of weight gain and a persistent belief that one is overweight, even when one is very thin. This cognitive-affective component of body image is typically measured using self-report questionnaires or interviews, where patients may express body dissatisfaction, an overvaluation of shape or weight, and a preoccupation with these factors.
People with anorexia often have a complex relationship with their body image, which involves negative feelings and appraisals. They may overestimate their body size, perceiving their own body as bigger than it is. This distorted body image can be a significant source of mental pain for individuals with anorexia, and it is an important factor to address in treatment. Research has shown that distorted body image, eating disorders, and depression symptoms can have a considerable impact on prolonging the illness and increasing the risk of relapse.
Body image distortion in anorexia can be understood as having two main components: the cognitive-affective component and the perceptive component. The cognitive-affective component involves the individual's thoughts, feelings, and beliefs about their body. This includes negative thoughts and feelings about one's body, such as body dissatisfaction and a fear of weight gain. The perceptive component relates to the individual's perception of their body size and shape. Individuals with anorexia often overestimate their body size, perceiving themselves as larger than they actually are.
The Body Dysmorphic Disorder (BDD) construct has been recognised in psychiatric literature, and it is characterised by an excessive concern with one's appearance. In anorexia, BDD can be particularly challenging to treat due to the patient's perception and cognitive focus on imagined defects, accompanied by high levels of anxiety and distress. It is important to note that individuals with anorexia may perceive the body shape or weight of those around them, including other patients, as normal, while having a distorted perception of their own bodies.
Treatment for anorexia often involves addressing body image distortion. However, only a few treatment approaches explicitly target body image, and even fewer focus on the perceptive component. There is a need for more research on how patients' perceptive body image changes after treatment and weight gain. By understanding the complex nature of body image distortion in anorexia, healthcare providers can develop more effective treatments and improve outcomes for individuals struggling with this disorder.

Laxatives and diuretics
Anorexia nervosa is a serious mental illness and eating disorder that involves severe calorie restriction and often a low body weight. People with anorexia nervosa often have an intense fear of weight gain and a distorted body image. They may think about food or calories almost all the time. To lose weight, some people with anorexia nervosa fast or exercise too much. Others may misuse laxatives and diuretics.
The misuse of laxatives and diuretics can result in several medical complications. Laxative abuse can lead to chronic diarrhoea, causing fluid loss and hypokalemia (low potassium) due to hormonal changes and the high potassium content of stool water. Diuretics can also contribute to overall increased water loss, leading to hyponatremia and potentially dangerous drops in sodium levels. The severe medical complications associated with eating disorders are often linked to electrolyte disturbances caused by laxative and diuretic misuse.
To address the misuse of laxatives and diuretics in individuals with anorexia nervosa, it is important to provide education and supportive interventions. Patients should be informed about the difference between water weight and weight from muscle or fat, as well as the importance of adequate hydration. By addressing the psychological dependency on these medications and improving understanding of bowel function, individuals can be helped to stop using laxatives and diuretics. Early diagnosis and treatment of anorexia nervosa are crucial for optimal recovery outcomes.
