What Is Anorexia Nervosa?
Anorexia nervosa, also referred to as anorexia, is an eating disorder. It is characterized by abnormally low body weight and an intense fear of weight gain. These feelings may further be accompanied by a distorted perception revolving around weight.
Individuals affected by anorexia severely restrict the amount of food they eat. This could be either to continue with their weight loss or to prevent gaining any extra kilos. In some cases, the individuals may also control their calorie intake by vomiting post eating, exercising intensively, or misusing laxatives for this purpose (2).
While anorexia is not a mental health disorder, some individuals may develop this life-threatening behavior as a way to cope with emotional problems. It can also affect pregnancies. Those still battling anorexia may exhibit deterioration in their symptoms whereas those who had been treated may have a remission. Those who had mild symptoms tend to have uncomplicated pregnancies (3).
The signs and symptoms of anorexia can be associated with starvation and can also be a result of emotional and behavioral issues.

While the exact cause of this eating disorder is not known, the following are some of the most common factors that may be involved in triggering anorexia.
Causes And Risk Factors
Anorexia may be triggered by a combination of biological, psychological, and environmental factors (2).
- Biological – Some genes could be involved in causing anorexia.
- Psychological – Those with an obsessive-compulsive personality trait or anxiety might be more likely to develop this condition than the others
- Environmental – Peer pressure and one’s surrounding culture that associates beauty with thinness can also further fuel the condition.
Some factors may also increase your risk of developing anorexia. They include:
- A family history of the condition
- Dieting or starving yourself can make it difficult to develop normal eating habits.
- Age – It is more common in teenage girls and women, but boys and men can also be at risk.
- Emotional stress and/or anxiety
Some of you may confuse anorexia with dieting. However, that should not be the case as both are completely different. The following are some of the major differences between the two.
Dieting Vs. Anorexia
- Anorexic individuals will restrict their diet to just a few hundred calories daily.
- Sudden weight loss
- Binge eating and purging
- Self-worth highly based on body shape and weight
However, dieting is usually aimed at getting a healthier body by consuming moderate amounts of healthy food without starving yourself.
- Those dieting will get all the necessary calories – but from healthy foods.
- Healthy dieting does not involve crash dieting. Instead, a person will lose weight gradually and will not be underweight or starved.
- Dieting does not involve starving. It mainly aims at substituting unhealthy foods with healthy ones.
- The food eaten is not purged.
- Those dieting are most often than not hardly obsessed with their weight. They eat healthy to feel healthy.
If you suspect that you or someone you know is suffering from anorexia, don’t shy away from seeking help.
Your doctor may carry out various tests and exams to pinpoint the cause of your symptoms and rule out other medical causes for weight loss (4).
Such diagnostic tests usually include:
- Physical examination that may involve measuring your height, weight, heart rate, blood pressure, and other symptoms
- An analysis of your family history
- Laboratory tests like a complete blood count test or other specialized blood tests to check your electrolytes, protein, as well as the functioning of your vital organs such as your liver, kidneys, and thyroid
- Psychological evaluation to evaluate your thoughts, eating habits, and feelings
- Other tests like an X-ray or electrocardiogram to find your bone density or heart irregularities (if any)
In case your tests prove that you are suffering from anorexia, your doctor may prescribe the following medical treatments to help you recover from the eating disorder successfully.
Available Treatment Options
Some of the available treatment options for anorexia nervosa are (4):
- Hospitalization – If your condition is critical, you may have to be hospitalized immediately. This usually happens when there are issues with your heart rhythm, or you are dehydrated or suffer from severe malnutrition.
- Tube Feeding And Frequent Monitoring – Your symptoms and vital signs like your hydration levels and electrolytes may need to be monitored frequently. In serious cases, patients may also need feeding via a tube.
- A healthy diet that is provided by a dietitian to help you get back to normal eating habits.
- Psychotherapy – Family-based, group, and individual therapy that will help an individual to make healthy food choices.
- Medications – While there is no particular medication for anorexia, the affected individuals may be given antidepressants and psychiatric medications to treat other symptoms like depression and anxiety.
Following a healthy diet is very necessary to treat anorexia. However, since anorexia is a serious condition, do not self-medicate. Instead, consult a dietitian who may provide diet tips to help you get back to a normal eating pattern.
How To Deal With Anorexia
When it comes to restoring the lost weight, anorexic individuals should follow a specific meal plan provided by a professional dietitian.
However, some affected individuals could be at risk of the refeeding syndrome, where one’s body may react negatively to a sudden increase in their food intake. In such a scenario, a medical team that consists of a doctor and a Registered Dietitian Nutritionist (RDN) should calculate, monitor, and increase the affected individual’s food and fluid intake during the refeeding phase.
For those who are not at risk of the refeeding syndrome, it is not uncommon for their calorie needs to reach 3000-5000 calories daily. This is especially the case for affected adolescents who are still growing and young. Such individuals can safely start by eating 2000-2500 calories per day and increase their calorie intake to 3000-5000 daily calories.
Your aim is to reach a diet where 50-60% of the total calories come from healthy carbohydrates, 15-20% from protein, and 30-40% from healthy fats.
Healthy carbohydrates include vegetables, whole fruits, legumes, nuts, seeds, and whole grains.
Protein-rich foods include seafood, dairy, eggs, oats, and soy.
You can get healthy fats from avocados, dark chocolate, whole eggs, fatty fish, nuts, and olive oil.
Here are a few tips to manage anorexia.
Tips To Manage Anorexia
- Stick to your treatment plan by not missing any therapy sessions and not skipping meals.
