Global cases of anorexia and bulimia rose by 71 percent between 1990 and 2023, with total diagnoses reaching 18.1 million. This persistent shift significantly affects young adults, with over 41 percent of all cases occurring in people between 10 and 24 years old.
Why it matters
The dramatic increase in these conditions highlights a growing public health challenge, particularly among young women who account for 70 percent of total diagnoses. Understanding these population-level trends is essential for improving early detection and support systems.
A retrospective report shows that global anorexia and bulimia cases reached 18.1 million by 2023, representing a 71 percent increase over the 1990-2023 period. While Australasia reports a high prevalence of 946.4 per 100,000, researchers are still determining the root causes for the variance across different regions.
The players
Brazilian scientists
A research group focused on neurobiology and the identification of brain circuits linked to behavioral compulsions.
The details
Neurological research from 2024 suggests that specific sets of neurons regulate the compulsion to seek food without physiological hunger. When this brain area is either inhibited or stimulated, it can trigger behaviors mimicking binge eating or restrictive anorexia. Scientists continue to study how this circuitry might eventually inform new therapeutic approaches for eating disorders.
Timeline
1990-2023: Global cases of anorexia and bulimia increased by 71 percent.
2023: Total diagnostic count reached 18.1 million people.
2024: Researchers identified neurons related to compulsive food seeking.
Health Landscape
The rising prevalence of eating disorders, which now affects 18.1 million people, marks a departure from historic diagnostic rates. Current research is increasingly focused on mapping the neurobiological pathways that drive these conditions, shifting the clinical focus toward brain-based interventions.
Individuals concerned about disordered eating patterns should consult a physician to discuss early intervention options, as 41.2 percent of cases occur in people aged 10 to 24. Recognizing early signs of compulsive food-seeking behavior is a vital step in seeking appropriate, evidence-based support.
The takeaway
Eating disorders are complex conditions that appear to have a strong neurological component, as evidenced by recent brain circuit research. If you or a loved one notice signs of restrictive eating or binge behaviors, prioritize a conversation with a primary care doctor or a licensed mental health professional.
