Eating Disorders Practice Questions

Q: A 16-year-old girl has intense cravings for food and consumes large amounts of it, followed by purging behaviors. What is the most likely diagnosis?

Bulimia nervosa. ***Bulimia nervosa*** - **Bulimia nervosa** is characterized by recurrent episodes of **binge eating** (consuming large amounts of food with a sense of lack of control), followed by inappropriate **compensatory behaviors** such as self-induced vomiting, laxative abuse, or excessive exercise. - The patient's presentation of "intense cravings for food," consuming "large amounts," and "purging behaviors" directly aligns with DSM-5 diagnostic criteria for bulimia nervosa. - Peak onset is typically in **adolescence and early adulthood**, and it is more common in females. *Anorexia nervosa* - **Anorexia nervosa** is primarily characterized by **restriction of energy intake** leading to significantly low body weight, intense fear of gaining weight, and disturbance in body image. - While the binge-eating/purging subtype of anorexia exists, the defining feature is **persistent restriction** and significantly **low body weight**, which is not mentioned in this clinical scenario. *Major depressive disorder* - **Depression** is a mood disorder with persistent sadness, anhedonia, and neurovegetative symptoms. - While depression commonly co-occurs with eating disorders and may cause appetite changes, the specific cyclical pattern of **binge eating followed by compensatory purging** is not a characteristic feature of depression itself. *Binge eating disorder* - **Binge eating disorder** involves recurrent episodes of consuming large amounts of food with a sense of lack of control, accompanied by marked distress. - The key distinguishing feature is the **absence of regular compensatory behaviors** (purging, excessive exercise, fasting) that are present in bulimia nervosa.

Q: Which of the following is not typically seen in anorexia nervosa?

Menorrhagia. ***Menorrhagia*** - **Anorexia nervosa** is typically associated with **amenorrhea** (absence of menstruation) or **oligomenorrhea** (infrequent menstruation) due to hormonal imbalances caused by malnutrition and low body fat. - **Menorrhagia** (heavy or prolonged menstrual bleeding) is not a common feature and would suggest a different underlying cause. *Osteoporosis* - **Osteoporosis** is a common and serious complication of **anorexia nervosa** due to prolonged low estrogen levels, poor nutrition, and hormonal dysregulation affecting bone density. - Reduced **bone mineral density** is prevalent, especially in chronic cases. *Food refusal* - **Food refusal** is a hallmark symptom of **anorexia nervosa**, driven by an intense fear of gaining weight and a distorted body image. - Patients restrict food intake, often leading to severe caloric deficit. *Weight loss* - Significant **weight loss** is a diagnostic criterion for **anorexia nervosa**, as individuals maintain a body weight that is minimally normal or even below normal for their height and age. - This weight loss is intentionally achieved through restrictive eating behaviors.

Q: Which eating disorder is characterized by episodes of binge eating while maintaining a normal weight?

Bulimia nervosa. ***Bulimia nervosa*** - This disorder is characterized by recurrent episodes of **binge eating** followed by compensatory behaviors such as self-induced vomiting, misuse of laxatives, or excessive exercise, while the individual generally maintains a **normal body weight**. - The key differentiator from anorexia nervosa is the **normal weight** and the cyclical pattern of binging and compensatory behaviors. - According to **DSM-5 criteria**, bulimia nervosa requires both binge eating episodes and inappropriate compensatory behaviors occurring at least once weekly for 3 months. *Anorexia nervosa* - This eating disorder is primarily characterized by an intense fear of gaining weight, leading to **severe restriction of food intake** and significantly **low body weight**. - Individuals with anorexia nervosa do not maintain a normal weight; rather, their weight is often **below minimally normal** (BMI < 18.5 kg/m² in adults). *Binge eating disorder* - This disorder involves recurrent episodes of **binge eating**, defined as consuming an unusually large amount of food in a short period with a sense of loss of control, but it does **not involve recurrent compensatory behaviors** like purging. - Individuals with binge eating disorder are often **overweight or obese**, contrasting with the normal weight seen in bulimia nervosa. *Night eating syndrome* - This disorder is characterized by recurrent episodes of **nighttime eating** (consuming food after evening meal or upon awakening from sleep) with full awareness. - Unlike bulimia nervosa, it does **not involve binge eating** in the classic sense, and there are **no compensatory behaviors** like purging or excessive exercise. - Individuals may maintain normal weight but the eating pattern is distinctly different from the binge-purge cycle.

Q: What does Pica refer to?

An appetite for non-nutritive substances. ***An appetite for non-nutritive substances*** - Pica is an eating disorder characterized by a persistent and compulsive craving for and consumption of **non-nutritive, non-food substances** for at least one month. - Common ingested substances include **dirt, clay, ice, hair, paint chips, and laundry starch**, often associated with **nutritional deficiencies** like iron deficiency anemia or **developmental disabilities**. *Ice sucking* - While **pagophagia (ice craving)** is a specific form of Pica, it represents only one manifestation and not the overarching definition of the disorder. - Isolated ice sucking can sometimes be a sign of **iron deficiency anemia**. *Thumb sucking* - **Thumb sucking** is a common habit, especially in infants and young children, typically associated with self-soothing and comfort. - It is not considered an eating disorder and does not involve the consumption of non-nutritive substances. *None of the options* - This option is incorrect because "An appetite for non-nutritive substances" accurately defines Pica.

Q: Disorder where amenorrhea was once needed for diagnosis is?

Anorexia nervosa. ***Anorexia nervosa*** - Historically, **amenorrhea** (absence of menstruation) was a diagnostic criterion for **anorexia nervosa**, reflecting the severe physiological impact of malnutrition and low body weight on the **endocrine system**. - While still common in patients with anorexia, it is **no longer a mandatory diagnostic criterion** in the DSM-5. *Metabolic syndrome* - Metabolic syndrome is a cluster of conditions that includes **increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels**. - It is **not directly associated with amenorrhea** and does not have amenorrhea as a diagnostic criterion. *Bulimia nervosa* - Bulimia nervosa is characterized by **recurrent episodes of binge eating** followed by compensatory behaviors such as self-induced vomiting, excessive exercise, or misuse of laxatives. - While it can be associated with menstrual irregularities due to nutritional imbalances, **amenorrhea is not a diagnostic criterion** for bulimia nervosa. *Binge eating disorder* - Binge eating disorder involves **recurrent episodes of eating large quantities of food**, often rapidly and to the point of discomfort, without the regular use of inappropriate compensatory behaviors. - This disorder is **not directly linked to amenorrhea as a diagnostic feature**, although nutritional status can affect menstrual cycles.

Q: Excessive eating of non-nutritive substances is called:

Pica. ***Pica*** - Pica is an eating disorder characterized by the persistent eating of **non-nutritive, non-food substances** over a period of at least one month. - Common substances ingested include **dirt, clay, ice, paint chips, paper, and laundry starch**, indicating an unusual craving for non-food items. - More common in **children, pregnant women, and individuals with developmental disabilities**. *Anorexia Nervosa* - Anorexia nervosa is an eating disorder characterized by **restriction of energy intake** relative to requirements, leading to a significantly low body weight. - It involves an intense **fear of gaining weight** or becoming fat, and a disturbance in the way one's body weight or shape is experienced. - Does not involve eating non-nutritive substances. *Bulimia Nervosa* - Bulimia nervosa is characterized by **recurrent episodes of binge eating** followed by compensatory behaviors such as self-induced vomiting, misuse of laxatives, fasting, or excessive exercise. - Unlike Pica, it involves eating **excessive amounts of regular food**, not non-nutritive substances. *Rumination Disorder* - Rumination disorder involves **repeated regurgitation of food** that may be re-chewed, re-swallowed, or spit out, occurring after feeding or eating. - It involves **normal food substances**, not the persistent eating of non-nutritive items as seen in Pica.

Q: Repeated involuntary regurgitation of food is associated with which of the following disorders?

Rumination disorder. ***Rumination disorder*** - This disorder is specifically characterized by the **repeated regurgitation of food** either back into the mouth for rechewing and reswallowing or spitting out. - The regurgitation is **involuntary** and not due to a medical condition or another eating disorder. *Binge eating disorder* - Characterized by recurrent episodes of **eating a large amount of food** in a short period, accompanied by a feeling of loss of control. - Does not typically involve the **regurgitation of food** after consumption. *Bulimia nervosa* - Involves recurrent episodes of **binge eating followed by compensatory behaviors** such as self-induced vomiting, excessive exercise, or laxative misuse. - While vomiting occurs, it is a **compensatory behavior** after a binge, not an involuntary regurgitation as seen in rumination disorder. *Anorexia nervosa* - Primarily defined by a **restricted energy intake** leading to significantly low body weight, intense fear of gaining weight, and a disturbed perception of body shape or weight. - Does not involve the **repeated involuntary regurgitation of food** as a primary feature.
