Eating Disorders

The eating disorders most commonly treated in adults are anorexia nervosa, bulimia nervosa and more recently, binge eating disorder. In addition to these disorders, there is a significant subgroup of patients falling into the “otherwise specified” category who also need detection and treatment.  Eating disorders are considered complicated to treat because of the need to attend to medical, nutritional and psychiatric factors simultaneously.  A multi-disciplinary approach to treatment is therefore felt to be essential and is typical of specialized treatment programs.  The role of the primary healthcare physician and team is extremely important in the detection of individuals with an eating disorder, as well as in the medical monitoring and management of these patients.  As the “quarterback” of their patients’ healthcare, physicians are in an important position to advocate for their patients’ care as they navigate the eating disorder treatment options.  In many cases, physicians and other primary healthcare providers have to manage the care of patients while they wait for specialized treatment, and are responsible for following patients once they leave treatment.  Because of the ambivalence many patients feel about recovery, the primary healthcare team can be responsible for following patients over long periods of time, some of whom are very medically compromised.

Managing Patients Medically

The primary care physician and team often must provide medical evaluation and monitoring of patients who are identified as having an eating disorder. The St. Joseph’s Eating Disorders Clinic has prepared a brief list of recommendations for medical monitoring of eating disorder patients, which is also available on their website.

Levels of Care

Eating disorders vary in severity and medical risk which require different levels, or intensity, of treatment. Primary physicians can help direct patients to appropriate care:

Outpatient Treatment:

Description: Typically individual or group therapy offered once per week. Additional support often provided by dietitian (for nutritional needs) and nurse practitioner (for medical needs) and psychiatrist (to help address comorbid psychiatric illnesses).

Appropriate for:  Individuals with a Body Mass Index (BMI) over 16; no serious medical complications or risk factors (e.g., type 1 diabetes); individuals who believe they can make changes to their eating, activity or symptoms in their home environment with support and guidance.

Day Treatment:

Description:  Typically treatment runs 5 days per week, and includes 2 supervised meals and snacks as well as different group treatment groups offered throughout the day.

Appropriate for:  Individuals with a BMI over 15; may have medical complications or significant risk factors (e.g., type 1 diabetes); individuals who feel that they will need supervision and support to change their eating, activity or symptoms.

Inpatient Treatment:

Description: Patient is hospitalized; all meals and snacks are supervised; different treatment groups and/or individual therapy offered throughout the day; will eventually transition to day treatment and/or individual outpatient treatment.

Appropriate for:  Individuals whose BMI is below 15; typical at high medical risk related to weight and/or other factors; individuals whose motivation may be low and require close supervision and support to make changes.

Types of Eating Disorders and Screening Tools

The types of eating disorders most often seen in adulthood are anorexia nervosa, bulimia nervosa, binge eating disorder, and the “other specified” category that includes milder versions of the disorders just mentioned as well as purging disorder and night eating syndrome. Another eating disorder most commonly found in children, but that also occurs in adults is avoidant/restrictive food intake disorder (ARFID).   In assessing for anorexia, bulimia or binge eating disorder (or other specified disorders), if the patient presents with concerns that they have an eating disorder, it is typically not necessary or advisable to investigate other possible medical conditions.  In the case of ARFID, the symptoms may be the direct result of another medical condition, but the severity of food avoidance or weight loss exceeds that expected.

A General Screening Tool: The SCOFF

1.      Do you make yourself Sick (vomit) because you feel uncomfortably full?

2.      Do you worry that you have lost Control over how much you eat?

3.      Have you recently lost mOre than 14 lbs. in a 3-month period?

4.      Do you believe yourself to be Fat when others say you are too thin?

5.      Would you say that Food dominates your life?

How to interpret the questionnaire: each “yes” equals 1 point; a score of 2 indicates a likely diagnosis of anorexia nervosa or bulimia.

For more information on the SCOFF please see – The SCOFF questionnaire: a new screening tool for eating disorders West J Med. 2000 March; 172 (3): 164–165. John F Morgan, Fiona Reid, and J Hubert Lacey 

Anorexia Nervosa (AN): A person with anorexia nervosa will have deliberately set out to either lose weight or control their eating (for example, to eat “clean” or more healthily) and will have experienced a significant weight loss, falling below what is considered minimally normal (a Body Mass Index below 18.5 at minimum).  Despite this low weight, the person with anorexia intensely fears the possibility of weight gain, or cannot seem to sustain behaviour that will lead to weight regain.  Their self-evaluation is unduly influenced by their feelings about their weight or shape and they may have difficulty recognizing the seriousness of their low body weight.  Some individuals are designated as “restricting type” if they only restrict their food intake and/or over-exercise.  Others would be described as “binge-eating/purging type” if either binge eating or any type of purging of food (through self-induced vomiting, laxatives, etc.) is part of the clinical picture.  The severity of anorexia is related to the extent of weight loss.  Individuals whose BMI is above 16 are eligible for treatment in an outpatient setting and are considered to fall in the “mild to moderate” range.  Individuals falling below this range (“moderate, severe and extreme”) would be considered appropriate for intensive treatment such as day hospital or inpatient care.

Screen for Anorexia Nervosa:

1.      What is the most you have ever weighed? When was that?

2.      What is the least you have every weighed? When?

3.      What do you think you should weigh?

4.      When you look in the mirror do you think you should gain weight, lose weight or stay the same?

5.      How often do you exercise each week? How long does each session last?

6.      Is your menstrual cycle regular?

7.      Have you ever felt like you lost control over your eating and eaten more than you should? Would others agree that it was a lot of food to have eaten in that situation?

8.      Have you ever felt so uncomfortable with what you have eaten that you tried to get rid of it some way? How did you try to get rid of the food?

Bulimia Nervosa (BN):

Persons with bulimia nervosa are typically trying to restrict their food, but are experiencing recurrent episodes of binge eating, where they experience a loss of control over their eating and eat what most people would consider to be a large amount of food compared to what people would typically eat in similar circumstances. The person with bulimia usually feels very distressed at this loss of control and tries to make up for it through various methods of compensating for the food they have eaten.  The compensatory strategy that most people associate with bulimia is self-induced vomiting, but there are other strategies such as misuse of laxatives, diuretics or other medications; fasting; or excessive exercise that individuals with bulimia use to try to rid themselves of the food they have eaten.  The binge eating and compensatory behaviours must both occur, on average, at least once a week over at least a three month period.  It is understood that what drives the food restriction, and the attempts to make up for the binge eating, is that their self-worth is based on weight and shape.  The severity of this disorder is related to the frequency of inappropriate compensatory behaviours, in part because this is also related to the medical risk associated with the disorder.  Individuals in the mild to moderate range are using compensatory behaviours up to once per day.  Individuals in the severe to extreme range are using compensatory behaviours more than once or twice per day.  These patients are at the greatest medical risk, especially when using strategies such as vomiting or laxative abuse. 

Screen for Bulimia Nervosa:

1.      Would you say that your weight and shape has a big impact on how you feel about yourself?

2.      Some people eat large quantities of food in an out of control way. Does this ever happen to you?

3.      Many people, after eating this way, feel very badly. Do you ever feel badly about yourself after eating in this way?

4.      Many people then try to compensate for this eating by getting rid of the food or compensating for it somehow. Has this ever happened to you?

a.      Have you ever tried to make yourself sick/vomit?

b.      Have you ever taken laxatives?

c.      Have you ever exercised to make up for a meal/snack/binge?

5.      How frequently do you exercise each week and how long does each session last?

6.      What is your motivation for exercising?

7.      Do you feel your exercise is out of control?

 Binge Eating Disorder (BED):

Persons with binge eating disorder are experiencing recurrent episodes of binge eating, where they experience a loss of control over their eating and eat what most people would consider to be a large amount of food compared to what people would typically eat in similar circumstances. They are not, however, engaging in any behaviours to compensate for the food that they have binge eaten.  Because of this, persons with binge eating disorder are typically overweight or obese, and may first come to your attention because they are seeking weight loss of some kind.  Binge eating is not simple overeating, as it is associated with at least three of the following: eating more rapidly; eating until uncomfortably full; eating large amounts even when not hungry; eating alone because of embarrassment about the eating; and feeling disgusted, depressed or guilty after eating.  The binge eating must be occurring on average once a week for at least a three month period.  Severity of the disorder is related to the frequency of binge eating.  Individuals in the mild to moderate range are binge eating up to once per day.  The severe to extreme range is when individuals are binge eating more than once or twice per day.

Screen for Binge Eating Disorder:

1.                Has your weight fluctuated much over the last few years?

2.                Some people eat large quantities of food in an out of control way. Does this ever happen to you?

3.                Many people, after eating this way, feel very badly. Do you ever feel badly about yourself after eating in this way?

4.                Many people then try to compensate for this eating by getting rid of the food or compensating for it somehow. Has this ever happened to you? (Rule out)

a.  Have you ever tried to make yourself sick/vomit?

b.  Have you ever taken laxatives?

c.   Have you ever exercised to make up for a meal/snack/binge?

 Avoidant/Restrictive Food Intake Disorder (ARFID):

Persons with ARFID experience significant weight loss or nutritional deficiencies, require enteral feeding or oral nutritional supplements, or experience significant impact on their psychosocial functioning because of an inability to eat.  The reason for these difficulties is because the person refuses to eat because they say they are not interested in eating or food; because they cannot tolerate the sensory qualities of food; or are worried about a negative consequence of eating (such as worrying they might choke, vomit or have symptoms of irritable bowel as examples).

Hospital (St. Joseph’s Healthcare Hamilton) Based Resources

St. Joseph’s Eating Disorders Clinic

The St. Joseph’s Eating Disorder Clinic provides psychiatric assessment and pharmacotherapy, as well as cognitive behaviour therapy for patients with the following conditions:

  • Anorexia Nervosa (for individuals with a Body Mass Index [BMI] over 16)
  • Bulimia Nervosa
  • Binge Eating Disorder
  • Avoidant/Restrictive Food Intake Disorder
  • Other Specified Feeding and Eating Disorder, including Purging Disorder and Night Eating

Please note the following restrictions and recommendations:

  • St. Joseph’s Eating Disorders Clinic is an outpatient program does not treat individuals whose eating disorders place them at high medical risk. Individuals whose BMI falls below 16 should be referred to more intensive eating disorder programs, such as Credit Valley Hospital, Toronto General Hospital, or London General Hospital. In these settings, individuals are more closely monitored medically and receive more support for making changes. Other individuals may be recommended to a higher level of care based on the assessment of medical risk due to other factors related to their eating disorder.
  • The clinic may recommend alternative treatment for individuals with significant self-harm, substance abuse or psychotic disorders.

Please contact Ms. Seana Jackson-Brown if you have any questions about referring a patient to the eating disorders clinic.
