Are you preoccupied with your calorie intake because you think you tend to gain too much weight? You might be suffering from anorexia nervosa, which is a type of eating disorder. It’s extremely dangerous because it can lead to malnutrition or extreme levels of weight loss.  

So, it is important to note the signs of this disease and manage them to avoid these complications.  

Anorexia nervosa is a type of eating disorder where people get obsessed with gaining weight and try to do everything to lose weight. They are preoccupied with their calorie intake and weight, which can result in severe weight loss or in some cases malnutrition too. To lower their weight, they even start to exercise intensively and start avoiding meals or eating very little. Although, it can happen to anyone mostly found in adolescent or young women. Treatment often uses several strategies like nutritional counseling, medications, psychological therapy, or hospitalization.  


What exactly causes anorexia nervosa is unknown. But doctors say people develop a negative image in their minds about their body weight; that if they gain weight, they will look bad. And they want to stay perfect every time. Researchers think it is a combination of biological, psychological, and environmental factors.  

  1. Biological factors: Genetic mutation or hormone changes can lead to anorexia nervosa. Researchers suggest that 50 to 80% of cases of anorexia nervosa are genetic. If your parents or relatives have any kind of eating disorder, the chances of developing the eating disorder are increased by 10 times. Hormones like dopamine or serotonin also play a big role in affecting appetite and are related to eating disorders.  
  2. Psychological factors: Some people have mental conditions like obsessive-compulsive disorder which makes them obsessed about diet and workout to make sure they look perfect every time they see themselves in a mirror. They don’t even eat even if they are hungry. They might suffer from elevated levels of anxiety. In children, peer pressure to look slim might be the reason to develop anorexia.  
  3. Environmental factors: Environmental and cultural influence through social media, ads, films, magazines, etc. become the reason to develop anorexia.  

While these factors apply to most people, not all develop anorexia.
