Information for Providers

PCPs should always screen for eating disorders (ED) as they are often the first clinician to recognize the signs of an ED. The importance of early assessment and treatment for EDs cannot be underestimated. treatment is most effective when delivered early and early intervention helps prevent serious physical and psychological consequences. Therefore, we’ve curated this page to provide resources and assist you in screening for eating disorders. 


important facts about eating disorders

  1. 30 million Americans (10% of the population) will be affected by an eating disorder in their lifetime

  2. Evidence suggests that the higher a person's BMI, the greater the likelihood that they meet the criteria for an eating disorder. For this reason, a screening process that relies heavily on BMI is likely to miss the bulk of individuals in a primary care setting who would benefit the most from early identification and intervention.

  3. Eating disorders are the second deadliest mental illness, following opioid addiction, with a mortality rate of 4-5 percent. The good news, however: eating disorders are very treatable with early detection and proper treatment. Unfortunately, most medical schools and residency programs don’t provide adequate education on eating disorders.

  4. 80% of Americans with an eating disorder will never receive treatment. Less than 20% of those who receive treatment will receive evidence-based treatment.

  5. Less than 6% of people with eating disorders are medically diagnosed as “underweight”


questions to assist in screening for an ED

Have there been weight changes since the last visit? (gain or loss) 

  1. A reminder that EDs do not discriminate based on weight, size, shape, gender, race, ethnicity, age, etc.

  2. Due to this, the patient may see nothing wrong with these behaviors and may be seeking validation, particularly if they are experiencing weight loss.

  3. Inquire whether or not the patient has noticed these changes. If so, ask if the weight change was intentional or unintentional.

For adolescent clients, regardless of BMI: have they fallen off the growth curve? Experiencing slowed height velocity? Stagnant growth curve?

  1. Shifts up could indicate binge-eating, while shifts down and a stagnant curve could indicate restriction.

  2. Shifts up or down could indicate purging.

  3. Weight loss in childhood throughout teenage years is not normal.

Changes in food intake and behavior: Has your patient mentioned dieting behaviors such as cutting out food groups, counting calories, fasting, suddenly following a vegetarian/vegan diet or self-proclaiming food allergies/intolerances?

  1. Navigating diet behaviors is extremely challenging given the pervasive normalization of ‘wellness’ and weight loss in our culture.

  2. Because of this, the patient may see nothing wrong with their behavior and is seeking positive affirmation from you, particularly if the client is in a larger body and losing weight.

  3. Even though patients may present positive health intentions, it is NOT normal for most people to cut out food groups, obsessively count calories, or abide by rigid food rules. These signs may be warnings that something else is going on or that the client has a skewed relationship with food.

Are there compensatory behaviors around food or “guilt” associated with eating?

  1. Patients often do not disclose compensatory behaviors. It is 100% within your scope of practice to ask direct questions regarding this.

  2. Compensatory behaviors include: purging by vomiting or laxative, Diuretic or diet pill use, insulin abuse, restriction, and exercising to ‘burn-off’ food.

  3. Folks with EDs tend to find that their thoughts throughout the day are often preoccupied by food. Research suggests this preoccupation with food results from restriction-type behaviors.

  4. Having the “good” vs “bad” attitude towards foods (Do you label food good vs bad?)

Do your clients report frequent GI discomfort or describe very restrictive diets to manage their GI symptoms?

  1. Folks with EDs frequently experience GI related medical complications; these complications can potentially increase severity of symptoms.

  2. Behaviors such as restricting, binging, purging, laxative abuse, or diuretic use, will generally disrupt normal digestion creating issues such as slowed gastric emptying, constipation, bloating, or general abdominal pain.

  3. GI distress could lead to disordered eating behaviors especially if they are following a very restrictive diet

Do your patient’s vital signs and physical findings suggest medical instability or abnormalities?

  1. Bradycardia, tachycardia, high/low blood pressure, alopecia, cold or bluish extremities, pallor, enamel erosion or enlarged parotid glands (signs of purging), lanugo, Russell sign (callous on knuckles from purging), decreased bowel sounds, palpable stool, yellow tint of the skin, swelling of lower extremities, decreased mobility, and muscle wasting in the temporal, clavicular, or scapular region, are all physical signs of EDs.

  2. Eating disorders can lead to a variety of abnormal lab values including, but not limited to, low: B12, electrolytes, iron, and white blood cell count; as well as elevated: liver enzymes (AST & ALT), amylase, BUN (indicative of dehydration), and cholesterol levels. 

  3. You can read more about physical signs of eating disorders and how physicians can screen for them in a blog by Dr. Jennifer Gaudiani.

A simplified series of screening questions is broken down using the “SCOFF”

The ‘‘SCOFF’’  

S   Do you make yourself SICK (vomit) because you feel uncomfortably full?

C   Do you worry that you have lost CONTROL over how much you eat?

O   Have you recently lost more than ONE stone (14 pounds) in a 3-month period?

F    Do you believe yourself to be FAT when others say you are thin?

F    Would you say that FOOD dominates your life?

Cut off: 2 or more abnormal responses has sensitivity of 100%, specificity of 87.5% for an eating disorder.

Performing a Medical Work-Up

  • Questions to consider:

    • Will knowing this information make it easier or more difficult to move toward valued goals?

    • What is there to learn from the discomfort of knowing vs. not knowing?

    • If a client feels strongly about knowing vs. not knowing, what is there to learn from this energy?

    • Dietitians: discuss with the patient what they think would be most helpful and why (what is our opinion for this particular client to do open or closed weights and why?)

    Once we’ve explored these questions, the decision to weigh or not may be different depending on the client.

    Blind Weight:

    Pro’s:

    • May be best to use until a level of recovery is met that refeeds the brain.

    • Reduce patient’s anxiety, fear, and stress around size, numbers, and recovery.

    Con’s:

    • Due to the CURES act, providers can no longer prevent patients from seeing their weights in medical charts.

    • If a client truly wants to know their weight, they will find a way to get that information.

    Seen Weight / Weight Trends:

    Pro’s:

    • Opportunity to work together through the anxiety that comes with size, numbers, and trends.

    • Helpful for some patients to see the progress they make week to week as they work towards their weight range goal.

    • Can help debunk a client’s belief that they are gaining more weight than they truly are.

    • Can be helpful to provide feedback to fixed mind by openly sharing the number on the scale.

    • Opportunity to help the client face change and have an open conversation about weight in session.

    • Weight can be viewed as feedback, and while this can be painful, it can help us learn and grow.

    • Feedback can be discussed and used for self-enquiry.

    • Opportunity to discuss the social signals that come with this feedback.

    Con’s:

    • For some patients, knowing their weight week to week can distract from behavioral change progress (how much time in session is it taking up?).

    • May send a patient into a spiral in response to such feedback.

    • May increase ED symptoms.

  • This can be done in a couple ways:

    Lie for 5 minutes: The patient should lie flat and still for 5 minutes – check and record heart rate and blood pressure

    Stand for 2 minutes: Patient should stand for 2 minutes – check heart rate and blood pressure

    Or

    Try out the “walk across the room test” with your patients.

    What this means is you take a patient’s resting heart rate and then have them do a lap or 2 across the room. Take the heart rate again. A true athlete’s heart with a healthy heart should stay around the same bpm. But in cases with eating disorders, the heart rate may double or triple. This is a malnourished heart.

    • Complete Blood Count (CBC) : It is common to see leukopenia, anemia, and thrombocytopenia in states of malnutrition due to bone marrow suppression or iron or vitamin deficiencies (B12, folate)

    • Comprehensive Metabolic Profile with Magnesium and Phosphorus

    • Normal levels of potassium are > 3.5, magnesium is > 1.8, and phosphorus is > 3.0

    • Elevated bicarbonate and amylase levels are both indicative of purging behaviors

    • AST and ALT can be elevated in states of malnutrition and are important markers to watch in cases of refeeding

    • TSH, Free T4, optional—Total T3: A low T3 with normal TSH and Free T4 is not a problem with the thyroid, but a marker of malnutrition

    • Electrocardiogram : Assess for arrhythmias, prolonged QTc, bradycardia

    • Urinalysis: This can determine the presence of ketones (a by-product of fat metabolism that occurs when the body doesn’t have enough fuel) and the urine specific gravity, which can assess dehydration and fluid intake

    • High cholesterol can also be an indicator of binge eating disorder or malnutrition

    • For hydration status check sodium, BUN, creatinine, eGFR

    • Leptin levels may be helpful in identifying the presence of hunger/fullness cues

Language is Powerful

if you’ve noticed a patient’s weight has changed

AVOID:

  1. Praising weight loss 

  2. Reinforcing the patient to “keep it up”

  3. Using exact numbers

CONSIDER:

  1. “I see your weight has changed since our last visit, what’s been going on?”

  2. “Have you been doing anything differently with your diet or exercise?”

  3. “I see a downward/upward trend, would you like to talk about some changes you’ve made?”

model positive body behavior

Rather than providing a comment directed at the patient’s body, consider commenting on their smile or energy. If the patient presents with a nervous demeanor, make sure you are giving good eye contact and a smile to alleviate the judgment they could potentially feel.

If a patient starts talking about a new diet/exercise routine which has aided in their weight loss:

AVOID:

  1. “Keep it up, you look great!”

  2. “I wish I had that kind of will-power!” 

  3. “I’m trying to avoid so many sweets myself, good for you!”

CONSIDER:

  1. “That’s quite a change, how are you feeling mentally as well?”

  2. “Rigid behaviors can be very hard to maintain–is this routine sustainable for you in the long run?”

  3. “I just had a really yummy cookie for lunch, which is your favorite kind?”
