[Eating disorders - diagnosis and characteristics].

Area of Science:

• Psychiatry
• Psychology
• Public Health

Background:

• Eating disorders are mental health conditions involving disturbed eating behaviors and appetite regulation.
• Anorexia nervosa, bulimia nervosa, and eating disorders not otherwise specified (EDNOS) are key types, with increasing prevalence in children and adolescents.
• These disorders have the highest mortality rate among mental illnesses, affecting predominantly young females but with rising cases in males and other age groups.

Purpose of the Study:

• To define and differentiate key eating disorders: anorexia nervosa, bulimia nervosa, and EDNOS.
• To highlight the rising incidence and demographic trends of eating disorders.
• To emphasize the critical need for increased awareness and specialized knowledge in diagnosing and treating these conditions.

Main Methods:

• Review of diagnostic criteria for anorexia nervosa (restrictive and bulimic types) and bulimia nervosa.
• Description of EDNOS as a category for eating disorders not meeting full criteria for anorexia or bulimia.
• Discussion of challenges in diagnosis, including lack of specialists and public awareness.

Main Results:

• Anorexia nervosa involves intentional weight reduction, distorted body image, and fear of weight gain.
• Bulimia nervosa is characterized by binge eating followed by compensatory behaviors (e.g., purging, excessive exercise).
• EDNOS encompasses pathological eating behaviors that do not fit standard diagnostic criteria.

Conclusions:

• Eating disorders represent a significant and growing public health concern, especially among adolescents.
• Effective diagnosis and treatment are hindered by a lack of specialists and insufficient public understanding.
• Public education and professional training are essential to combat the rising rates and severe outcomes of eating disorders.
