Beyond the Scale
Recognizing Eating Disorders and What Primary Care Can Do Today – Part I

The Diagnostic Challenge in Primary Care
Primary care physicians are frequently the first clinical contact for patients experiencing weight-related distress, yet these presentations rarely arrive with a straightforward diagnostic label. Instead, clinicians hear about frustration with weight, fatigue, changes in appetite or concerns about body shape. Within a brief visit, it can be difficult to determine whether these symptoms reflect disordered eating, mood disorder, hormonal dysregulation, substance use or the effects of pharmacologic weight loss therapy. Women with anorexia outnumber men by a 10:1 margin and are three to five times more likely to develop bulimia, as well.
Most clinical encounters approach weight concerns through a metabolic or behavioral lens alone, addressing caloric intake, physical activity and comorbid medical conditions. While necessary, this framework can unintentionally obscure the psychological complexity that frequently underlies weight-related distress in women. A patient who reports eating very little may be managing pharmacologic appetite suppression appropriately, or she may be in the grips of a restrictive eating disorder that has gone unrecognized for years.
This diagnostic fragmentation can delay recognition of serious psychiatric conditions and contribute to treatment strategies that are incomplete or even harmful. What is needed is a structured approach that prompts clinicians to look beyond the presenting complaint and assess the full spectrum of eating, behavioral and psychological risk.
A Structured Way to Think Through Eating-Related Presentations
To address this challenge, the EATH Diagnostic Framework was developed as a clinical heuristic for organizing the evaluation of weight and eating concerns in primary care. Rather than starting from a single suspected diagnosis, EATH encourages clinicians to move systematically through four major domains:
» E – Eating Behavior – Assessment of dietary patterns including restriction, fear of eating, rigid food rules, binge episodes, purging behaviors and the emotional meaning attached to food and eating.
» A – Addiction and Compulsive Patterns – Identification of maladaptive compensatory behaviors such as laxative misuse, stimulant use for appetite suppression, compulsive exercise and repetitive body checking.
» T – Trauma and Body Image History – Exploration of prior adverse experiences, body image disturbance, identity concerns related to weight or appearance and the degree to which perceived control over eating drives behavior.
» H – Hormonal and Metabolic Factors – Consideration of conditions such as polycystic ovary syndrome( PCOS), insulin resistance and the behavioral and psychological effects of pharmacologic weight loss therapies including GLP-1 receptor agonists.
