Eating disorders are serious psychological conditions that can have life-threatening physical consequences in men and women of any age.

They are commonly accompanied by extreme emotions, attitudes, and behaviours with regards to body weight and food. All eating disorders require professional help. Treatment for eating disorders involves psychotherapy, nutrition education, counselling, medication, and hospitalisation in severe cases.

Three common types of eating disorders include:
• Anorexia Nervosa: characterised by self-starvation and excessive weight loss
• Bulimia Nervosa: characterised by a cycle of binge eating followed by purging. Sufferers consume excessive amounts of food and then get rid of the food and calories through vomiting, laxative abuse, or over-exercising
• Binge Eating Disorder (Compulsive Overeating): characterised primarily by periods of uncontrolled, impulsive, or continuous eating beyond the point of feeling comfortably full

Causes of Eating Disorders

Exact causes of eating disorders are unknown. Researchers believe that it could be due to a complex interaction of biological, psychological, family, genetic, environmental, and social factors.

Possible causes of eating disorders include:
• Family history of siblings or parents with eating disorders, which suggest a possible genetic link
• Psychological issues such as low self-esteem, perfectionism, impulsive behavior, family conflicts, and troubled relationships
• Socio-cultural issues, such as peer pressure and the intense focus on one’s appearance and body shape in the media


Risk Factors

Factors to look out for, which may increase the risk of developing eating disorders include:
• Peer pressure, conventionally stronger in teenage girls and young women
• Parents and family members overly critical of body weight and outward appearance
• Other mental health disorders such as depression, anxiety, and obsessive-compulsive disorder (OCD)
• Stressful life transitions such as moving, broken relationships, or pregnancy
• Professions that focus strongly on outward appearance or weight regulations, such as acting, modelling, dancing and wrestling
