Beyond the scales: reframing eating disorder recognition in primary care

Eating disorders remain widely under-recognised in primary care, with harmful stereotypes and an overreliance on BMI often obscuring early diagnosis and intervention.

As hidden cases rise across diverse and often overlooked populations, Deanne Jade, founder of the National Centre for Eating Disorders, outlines the clinical realities, red flags and systemic gaps that pharmacists and frontline professionals must address to identify disordered eating earlier and more effectively.

When it comes to eating disorders the stereotypical image of a young, emaciated girl is not only deeply unhelpful it is a clinical trap that often hinders early intervention. In the high-pressure environment of primary care, recognition is obscured by several variables.

First, BMI is a poor indicator of medical and emotional risk.

Second, patients are often unwilling to admit to a serious problem, either due to deep seated shame or a belief that the clinician will not know how to respond.

Third, experience shows that patients with eating disorders frequently present with secondary conditions, such as anxiety or depression, yet are rarely questioned about their eating habits.

Fourth, there are many cohorts and demographics where a serious problem may be overlooked.

To truly reframe recognition of an eating disorder, community and practice pharmacists, and all medical professionals must move beyond the weighing scale and develop a ‘clinical hunch’ for the physiological and behavioural signatures of disordered eating hidden in plain sight. 

Prevalence

Many studies have attempted to identify the prevalence of eating disorders and there is a frequently cited baseline of 1.25 million people in the UK. The challenge of identifying hidden cases in the community, however, makes drawing a singular, firm conclusion impossible.

This figure of 1.25 million is a severe underestimate. It reflects only those individuals who have made contact with formal healthcare services, and completely misses the vast community burden of compulsive eating, binge eating, and hidden cases of bulimia often masked as recurrent weight problems.

Tracking mortality data is also complex. Deaths directly attributable to an eating disorder are frequently masked on death certificates, where the immediate cause is recorded as suicide or long-term physical complications of prolonged dietary chaos – such as acute cardiac arrest, electrolyte collapse, or organ failure.

Why BMI is not useful in this context

Eating disorders manifest in diverse forms among both sexes and require nuanced understanding.¹ Anorexia, often the most visible eating disorder, is a compulsion to achieve low weight driven by an intense fear of eating. Bulimia is characterised by binge eating followed by purging to avoid weight gain and sufferers may appear to be healthy and functioning well, when in fact they are very unwell. Compulsive eating, the third notable category, can involve anything from negligible to huge amounts of food.

In reality, there is a wide spectrum of eating disorder presentations that includes orthorexia – a compulsion to eat ‘clean’ food – and avoidant/restrictive food intake disorder (ARFID), which is increasingly seen in children who present with a very limited diet and associated malnutrition.

Atypical variants of specific eating disorders also complicate recognition. Not everyone with anorexia is observably thin; a young person may be in the grip of the illness and losing weight rapidly, but not yet ‘thin enough’ to fit a formal diagnosis. Such individuals are extremely unwell and require emergency intervention.

Furthermore, a young person may not look thin but may be failing to reach their expected growth trajectory. Similarly, bulimia and low weight anorexia carry severe cardiovascular risks, even in patients who appear to be a ‘normal’ weight.²

Red flags for the front line

Eating disorders are so widespread in the community especially among people living with obesity that they may be easily overlooked.³ Cohorts with a high prevalence who are often overlooked, include men, older adults (>65 years), athletes, type 1 diabetics, people with gender dysphoria, neurodivergent individuals, people in certain professions such as models or dancers, and racial-ethnic minority groups – all of whom are subject to specific stressors.⁴

For those in primary care, if weight decline and food avoidance are suspected, medical staff must consider the ‘cold and tired’ quartet: bradycardia (pulse <60 bpm), hypotension, tiredness, and hypothermia. These symptoms are key signs of restrictive eating disorders of clinical significance.

Psychological features, such as low mood, overexercise, and social withdrawal, are equally telling. Denial is a common feature of anorexia; therefore, tests for medical risk must be performed irrespective of a patient’s protestation that they are simply ‘working hard’ or ‘stressed.’

If a patient sits silently, refusing to talk, while wearing multiple layers in a warm clinic, the clinician must look deeper.

There are far more reliable indicators of physiological starvation than a weight chart.

Over-eating disorders are harder to identify without prior admission and physical cues like parotid gland swelling or Russell’s sign – marks on the hand caused by self-induced vomiting – are easy to miss.

We at the National Centre For Eating Disorders (NCFED) have invited primary care physicians to routinely ask patients attending for any emotional problem – be it insomnia, anxiety, or depression – to describe their relationship with food on a scale from 1 (dire) to 10 (great).

This short experiment has shown that disordered eating is common among those attending medical practices and merits professional help. When patients attend specifically for weight control, the sick, control, one, fat, food (SCOFF) questionnaire is an essential tool; any single ‘yes’ is a mandate for further investigation, regardless of BMI.⁵

The pharmacist as intermediary

The community pharmacy is an underutilised diagnostic space. Patients who are ‘scale-shy’ often visit their pharmacist to buy laxatives or enquire about weight loss drugs. However, in many pharmacies, the clinician is typically not first point of contact for customers. Instead, pharmacies often rely on non-clinical staff to manage the counter, meaning vital clues are lost.

For the pharmacy to function as a diagnostic hub, the public must be made aware – via pamphlets or posters – that the pharmacist is available for confidential discussions regarding disordered eating.

Furthermore, the frequent, recurrent purchase of laxatives, diuretics, or non-prescription weight loss remedies should prompt a sensitive, professional enquiry to facilitate a safe pathway to proper care.

The weight loss medication paradox

People seeking weight loss support have an elevated risk of disordered eating. Therefore, the surge in demand for GLP-1 receptor agonists – through online pharmacies or GP referrals – represents a new high-risk screening frontier, as these medications may be misused by those with severe eating disorders to reinforce food restriction.⁶

Pharmacists must challenge the assumption that every request for these drugs is an objective pursuit of health. Dispensing these drugs without rigorous screening risks overlooking a mental health condition that requires psychological attention.

Extreme distress at minor weight fluctuations or an obsession with rapid results are clinical red flags. Are we treating a metabolic issue, or accidentally facilitating an eating disorder?

How to enquire sensitively

People with eating disorders are notable for ambivalence to change. The patient often perceives their behaviour as a solution to distress rather than a problem.

Direct questions like ‘Are you eating enough?’ or ‘Do you have an eating problem?’ are ineffective and invite denial. Similarly, telling a patient they ‘don’t seem too bad’ is often interpreted as a sign that they are still ‘too fat.’

It is more helpful to use open ended, behaviourally focused questions:

• ‘How much of your day is consumed by thoughts of food, calories, or exercise?’
• ‘Do you feel that your self-worth is entirely dependent on the number on the scale?’
• ‘Do you ever think that eating rules your life?’

This shift moves the conversation away from shame and towards the burden of the illness.

Advocacy and the MEED Framework

Primary care practitioners are the first line of defence for robust advocacy. The Medical Emergencies in Eating Disorders (MEED)⁷ framework provides objective markers for the transition from ‘disordered styles of eating’ to ‘dangerously ill,’ and this is not contingent on BMI. Furthermore, if a carer expresses worry, they are usually right; their concerns must be taken seriously.

Medical markers such as electrolyte disturbance, rapid weight loss, or an inability to stand without support must be understood as emergencies. In these instances, practitioners must act as the patient’s advocate, ensuring immediate secondary care assessment. We must stop waiting for patients to ‘motivate’ themselves when their brains are physically starved.

A call to clinical courage

Reframing recognition is an active process of challenging both the patient’s narrative and the system’s tendency toward inertia. Missing the signs and failing to recognise an eating disorder in time can have serious and potentially fatal consequences.

Pharmacists must be upskilled to recognise the problem and engage with reluctant or withholding patients. Recognition is the first act of recovery, and it begins with the clinician who has the courage to look ‘beyond the scale’.
