Binge Eating Disorder Indian Medical PG Practice Questions and MCQs
Question 1: Body dysmorphic disorder can be associated with all except
- A. Bulimia nervosa
- B. OCD
- C. Anxiety
- D. Mania (Correct Answer)
Explanation: ***Mania*** - **Mania** is a state of elevated, expansive, or irritable mood that is distinct from the persistent preoccupation with perceived bodily defects seen in **body dysmorphic disorder (BDD)**. - While agitation can occur in BDD, the core symptom profile of **mania**, including decreased need for sleep, grandiosity, and racing thoughts, is not a typical associated feature. *Bulimia nervosa* - **Bulimia nervosa** can co-occur with BDD, particularly when the perceived defects relate to body weight, shape, or specific body parts. - Both disorders involve intense preoccupation with body image and often lead to harmful behaviors to attempt to "correct" perceived flaws. *OCD* - **Obsessive-compulsive disorder (OCD)** shares strong phenomenological similarities with BDD, including intrusive thoughts (obsessions) and repetitive behaviors (compulsions). - BDD is often conceptualized as part of the **OCD spectrum**, with both disorders involving obsessive thoughts and repetitive behaviors related to specific concerns. *Anxiety* - **Anxiety disorders** are highly comorbid with BDD, as individuals often experience significant distress, fear of judgment, and social avoidance due to their perceived flaws. - The constant preoccupation and efforts to conceal or fix perceived defects can lead to chronic anxiety and panic attacks.
Question 2: Diagnostic criteria for Bulimia nervosa are all EXCEPT
- A. Lack of control over eating behaviour
- B. Self induced vomiting
- C. Presence of other psychiatric disorders (Correct Answer)
- D. Binge eating
Explanation: ***Presence of other psychiatric disorders*** - While psychiatric comorbidities like depression, anxiety, and substance abuse are **extremely common** in individuals with bulimia nervosa, they are **not a diagnostic criterion** for the disorder. - The DSM-5 diagnosis of bulimia nervosa focuses specifically on **eating behaviors** (binge eating), **compensatory mechanisms** (purging/non-purging), and the impact on self-evaluation, not on the presence of co-occurring mental health conditions. - This is the correct answer as it is **NOT** a diagnostic criterion. *Lack of control over eating behaviour* - This is a **core diagnostic criterion** of bulimia nervosa. - Individuals must experience a sense of **lack of control** over eating during binge episodes (feeling unable to stop eating or control what or how much they are eating). - This feeling of loss of control during binges is essential for diagnosis. *Self induced vomiting* - This is a **diagnostic criterion** as one of the inappropriate compensatory behaviors used to prevent weight gain after binge eating. - Other compensatory behaviors include misuse of laxatives, diuretics, enemas, fasting, or excessive exercise. - At least one type of compensatory behavior must occur regularly (average of once weekly for 3 months). *Binge eating* - This is a **fundamental diagnostic criterion** involving eating an amount of food that is definitely larger than what most people would eat in a similar period under similar circumstances. - Must occur in a discrete time period (e.g., within any 2-hour period) with a sense of lack of control. - Binge episodes must occur, on average, at least once a week for 3 months for diagnosis.
Question 3: Which eating disorder is characterized by episodes of binge eating while maintaining a normal weight?
- A. Anorexia nervosa
- B. Bulimia nervosa (Correct Answer)
- C. Binge eating disorder
- D. Night eating syndrome
Explanation: ***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.
Question 4: 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?
- A. Anorexia nervosa
- B. Bulimia nervosa (Correct Answer)
- C. Major depressive disorder
- D. Binge eating disorder
Explanation: ***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.
Question 5: Indoor management of anorexia nervosa is done on priority patients with:-
- A. Depression
- B. Amenorrhea
- C. Binging episodes
- D. Weight for height less than 75% of normal (Correct Answer)
Explanation: ***Weight for height less than 75% of normal*** - A **weight for height less than 75% of normal** (or **BMI <15 kg/m²**) indicates severe **malnutrition** and a high risk of medical complications, necessitating urgent inpatient care. - This level of **underweight** is a critical indicator for hospital admission in **anorexia nervosa** to prevent severe organ dysfunction, refeeding syndrome, and even death. *Depression* - While **depression** is a common comorbidity with **anorexia nervosa** and often requires treatment, it does not, by itself, warrant immediate inpatient management unless there are acute **suicidal risks**. - **Depression** is usually managed in an outpatient setting initially, with hospitalization being reserved for severe cases where safety is compromised. *Amenorrhea* - **Amenorrhea** (absence of menstruation) is a common symptom of **anorexia nervosa** due to hormonal imbalances caused by low body weight. - Though an indicator of significant caloric restriction, **amenorrhea** alone is not typically an immediate criterion for inpatient admission unless accompanied by other severe physical complications. *Binging episodes* - While **binging episodes** can occur in **anorexia nervosa** (specifically the binge-purging subtype) and can lead to electrolyte imbalances or medical complications, they are not the primary, stand-alone trigger for immediate inpatient admission. - The severity of **binging** and associated **purging behaviors** must be evaluated in the context of overall medical stability and weight to determine the appropriate level of care.
Question 6: A young lady presents with a history of repeated episodes of overeating followed by purging using laxatives. She is probably suffering from -
- A. Binge eating disorder
- B. Schizophrenia
- C. Anorexia nervosa
- D. Bulimia nervosa (Correct Answer)
Explanation: ***Bulimia nervosa*** - This condition is characterized by recurrent episodes of **binge eating** followed by inappropriate compensatory behaviors like **purging (e.g., laxative use)**, self-induced vomiting, excessive exercise, or fasting. - The patient's presentation of repeated overeating followed by purging with laxatives directly aligns with the diagnostic criteria for **bulimia nervosa**. *Binge eating disorder* - While it involves recurrent episodes of **binge eating**, it **does not include** the regular use of inappropriate compensatory behaviors such as purging. - Individuals with binge eating disorder typically experience significant distress about their binging but do not attempt to undo the caloric intake. *Schizophrenia* - This is a severe mental disorder characterized by **distortions in thinking, perception, emotions, language, sense of self, and behavior**, such as hallucinations and delusions. - It is a **psychotic disorder** and does not involve specific eating patterns or purging behaviors. *Anorexia nervosa* - This eating disorder is characterized by a persistent restriction of energy intake leading to a **significantly low body weight**, an intense **fear of gaining weight**, and a distorted body image. - Although some individuals with anorexia nervosa may engage in binge-purging type behavior, the primary defining feature is **significantly low body weight**, which is not mentioned in the patient's presentation.
Question 7: A young girl hospitalised with anorexia nervosa is on treatment. Even after taking adequate food according to the recommended diet plan for last 1 week, there is no gain in weight. What is the next step in management:
- A. Increase the caloric intake from 1500 kcal to 2000 kcal per day
- B. Increase fluid intake
- C. Increase the dose of anxiolytics
- D. Observe patient for 2 hours after meal (Correct Answer)
Explanation: ***Observe patient for 2 hours after meal*** - Patients with **anorexia nervosa** often engage in compensatory behaviors like **purging** or extensive exercise, which would counteract the effects of increased caloric intake and lead to a lack of weight gain despite consuming an "adequate" diet. - Observing the patient post-meal helps identify these behaviors and ensures that the ingested calories are actually being retained and utilized for weight restoration. *Increase the caloric intake from 1500 kcal to 2000 kcal per day* - Increasing caloric intake is a valid long-term strategy but is not the immediate next step when there's **no weight gain despite adequate intake**; the primary concern is identifying *why* the initial intake isn't leading to weight gain. - Doing so without addressing potential compensatory behaviors might only increase patient distress or lead to more intense purging/exercise. *Increase fluid intake* - While adequate **hydration** is important, it does not directly address the issue of **lack of weight gain** in anorexia nervosa, which is fundamentally a caloric deficit problem. - Increased fluid intake would not provide the necessary calories for weight restoration. *Increase the dose of anxiolytics* - Anxiolytics may help manage **anxiety** related to eating, but they do not directly promote **weight gain** or prevent compensatory behaviors. - This step does not address the core issue of why the recommended diet is not leading to weight gain.
Question 8: Pagophagia involves eating
- A. Sand
- B. Ice (Correct Answer)
- C. Salt
- D. Clay
Explanation: ***Ice*** - **Pagophagia** is a specific form of **pica**, characterized by a compulsive desire to consume **ice**, ice chips, or iced drinks. - It is often associated with **iron-deficiency anemia**, though the exact mechanism for this craving is unclear. *Sand* - The compulsive consumption of **sand** is known as **geophagy**, which is another form of pica. - This behavior is distinct from pagophagia and is not specifically linked to ice consumption. *Salt* - An excessive craving for **salt**, while sometimes indicative of an underlying condition (e.g., adrenal insufficiency), is not referred to as pagophagia. - **Pagophagia** specifically refers to the consumption of ice. *Clay* - The ingestion of **clay** is a specific type of **geophagy**, similar to eating sand. - It is a different form of pica and does not describe the selective craving for and consumption of ice.
Question 9: Which of the following is FALSE regarding Anorexia Nervosa:
- A. Decreased appetite (Correct Answer)
- B. Body image distortion
- C. Vigor exceeding physical ill being
- D. Weight loss
Explanation: ***Decreased appetite*** - Patients with anorexia nervosa typically experience **increased hunger** and **preoccupation with food**, despite efforts to restrict intake, rather than a decreased appetite. - The sensation of hunger often intensifies due to severe caloric restriction, making the statement "decreased appetite" false. *Body image distortion* - This is a core diagnostic criterion of anorexia nervosa, where individuals perceive themselves as **overweight** even when they are severely underweight. - The distorted body image drives their relentless pursuit of thinness and fear of weight gain. *Vigor exceeding physical ill being* - Patients with anorexia nervosa often display surprising **energy and hyperactivity** despite severe physical debilitation and malnutrition. - This "vigor" can be a mechanism to burn calories, suppress hunger, or avoid rest, exceeding what would be expected given their poor health status. *Weight loss* - **Significant weight loss** or failure to gain weight during growth is a defining characteristic of anorexia nervosa. - This weight loss is intentionally achieved through severe dietary restriction, excessive exercise, or purging behaviors.
Question 10: Main difference between anorexia nervosa and bulimia nervosa lies in:
- A. Symptomatology
- B. Weight (Correct Answer)
- C. Gender
- D. Age
Explanation: ***Weight*** - The primary differentiator is that individuals with **anorexia nervosa** are **underweight** (BMI < 18.5 kg/m²), while those with bulimia nervosa maintain a **normal or overweight BMI**. - A persistent restriction of energy intake leading to a significantly low body weight is a diagnostic criterion for anorexia nervosa, which is not true for bulimia nervosa. *Symptomatology* - While there is overlap in symptoms like **fear of gaining weight** and body image disturbance, the **presence of significantly low body weight** in anorexia nervosa and its absence in bulimia nervosa is the key differentiating factor, making "weight" a more precise answer. - Both disorders involve **compensatory behaviors** like purging, excessive exercise, or fasting, but the underlying weight status distinguishes them. *Gender* - Both anorexia nervosa and bulimia nervosa primarily affect **females**, though rates in males are increasing for both disorders. - As such, gender is not a defining characteristic that differentiates these specific eating disorders from each other. *Age* - Both disorders typically emerge during **adolescence or young adulthood**, with slightly different peak ages of onset. - Age of onset is generally a **shared characteristic** rather than a distinguishing feature between anorexia nervosa and bulimia nervosa.
