Eating Disorders: Causes, Symptoms, Diagnosis, Treatment, and Prevention
Eating disorders are serious mental health conditions that affect how people think and behave around food, weight, and body shape. Eating disorders are not a choice or a lifestyle, but rather a complex interaction of biological, psychological, and environmental factors, which can have severe physical and emotional consequences, and in some cases, can be life-threatening.
Some of the most common types of eating disorders are:
-
The condition anorexia nervosa is characterized by a fear of gaining weight, distorted body images, and very low body weight. Anorexics may severely restrict their food intake, exercise excessively, or use other methods to lose weight, such as vomiting or laxatives.
-
In bulimia nervosa, binge eating is followed by compensatory behaviors, such as fasting, vomiting, or overeating, in order to prevent weight gain. Despite having a normal or above-normal weight, people with bulimia often have a negative self-image and fear of becoming fat despite their normal or above-normal body weight.
-
It is characterized by frequent episodes of eating a large amount of food in a short time frame, often to the point of discomfort. During binge eating episodes, people may feel out of control, experience guilt, shame, or distress. They may also eat alone or in secret to avoid being judged.
Among other types of eating disorders, there is avoidant/restrictive food intake disorder (ARFID), pica, rumination disorder, and other specific feeding or eating disorder (OSFED).
Causes of Eating Disorders
In order to develop an eating disorder, a number of factors must be present. Some of these factors include:
-
There is evidence that eating disorders may run in families, which suggests that some people inherit genes that make them more likely to develop eating disorders.
-
A person with an eating disorder may have certain personality traits that make them more likely to develop unhealthy eating habits, such as perfectionism, low self-esteem, impulsivity, or obsessive-compulsive behavior.
-
Depression, anxiety, trauma, or stress may contribute to eating disorders in people with underlying mental health issues.
-
Those with eating disorders may be influenced by social pressures and expectations regarding their appearance, weight, and eating behaviors. These pressures and expectations may come from family, friends, peers, media, and culture.
-
A person with eating disorders may suffer from hormonal imbalances, nutritional deficiencies, or brain abnormalities that affect their appetite, metabolism, or mood.

Diagnosis of Eating Disorders
You should seek professional help as soon as possible if you suspect that you or someone you know has an eating disorder. A qualified health care provider can diagnose eating disorders based on your medical history, physical examination, and psychological assessment. Your blood, urine, or other body functions may also need to be checked.
Treatment of Eating Disorders
Depending on the type and severity of eating disorders, as well as the individual's preferences and needs, eating disorders can be treated differently. Treatment aims to restore normal eating patterns, improve physical health, and address psychological issues that contribute to eating disorders.
Treatment may involve a combination of:
-
In addition to monitoring your vital signs, providing nutritional supplements, correcting any medical complications, and prescribing medications to treat any coexisting mental health conditions, you may also receive medical care.
-
You may receive individual, group, or family therapy to improve your self-esteem and body image, learn about the causes and effects of your eating disorder, challenge your distorted thoughts and beliefs about food and weight, and develop coping skills and strategies to deal with stress and emotions.
-
The goal of nutrition counseling is to help you create a balanced and personalized meal plan that meets your nutritional needs and preferences, educate you about the role of food and nutrition in your health and well-being, and help you develop a healthy relationship with food and eating.
-
It may be helpful to join a group of people who have similar experiences and challenges with eating disorders, where you can express your feelings, thoughts, and struggles, and receive encouragement and feedback from others who understand your situation.
Prevention of Eating Disorders
You can reduce your risk of developing an eating disorder or help someone who may be at risk by taking the following steps.
-
Develop a positive and realistic body image based on your health, abilities, and personality, rather than external standards.
-
Dieting, fasting, and skipping meals can trigger unhealthy eating behaviors and increase the risk of bingeing and purging.
-
Provide your body with adequate calories, nutrients, and fluids by eating a balanced and varied diet that includes all the food groups.
-
You should listen to your body's hunger and fullness cues, and eat when you are hungry and stop when you are full.
-
You should enjoy food as a source of nourishment, pleasure, and social connection, rather than as a source of guilt, shame, or anxiety.
-
Instead of exercising for weight loss or control, exercise regularly for fun, fitness, and health.
-
When stress, trauma, or emotional problems affect your eating habits or self-image, seek help.
-
Support and respect yourself and others who have different body shapes, sizes, weights, or eating habits.
-
You can improve the chances of recovery and prevent serious complications by seeking professional help if you notice any signs or symptoms of an eating disorder in yourself or someone else.
