Eating Disorders Practice Questions

Q: Binge eating disorder is characterized by?

Obesity. **Explanation:** **Binge Eating Disorder (BED)** is characterized by recurrent episodes of eating large quantities of food (often very quickly and to the point of discomfort) accompanied by a feeling of a loss of control. Unlike Bulimia Nervosa, BED is **not** associated with regular compensatory behaviors (purging). 1. **Why Obesity is Correct:** Because there are no compensatory mechanisms (like vomiting or excessive exercise) to offset the high caloric intake during binge episodes, most individuals with BED are **overweight or obese**. It is the most common eating disorder associated with metabolic syndrome and obesity-related comorbidities. 2. **Why Other Options are Incorrect:** * **Normal weight:** While possible in early stages, it is more characteristic of **Bulimia Nervosa** (where purging maintains weight) or Binge-Eating/Purging type of Anorexia. * **Weight loss:** This is the hallmark of **Anorexia Nervosa**. In BED, the positive energy balance leads to weight gain. * **Self-induced vomiting:** This is a compensatory "purging" behavior. Its presence would shift the diagnosis to **Bulimia Nervosa**. **High-Yield Clinical Pearls for NEET-PG:** * **DSM-5 Criteria:** Binge episodes must occur, on average, at least **once a week for 3 months**. * **Key Distinction:** BED = Binging + No Purging + Obesity; Bulimia = Binging + Purging + Normal Weight. * **Drug of Choice:** **Lisdexamfetamine** is the only FDA-approved medication for BED. SSRIs (like Fluoxetine) are also used to manage associated impulsivity and depression. * **Psychotherapy:** Cognitive Behavioral Therapy (CBT) is the first-line psychological treatment.

Q: Bulimia nervosa is associated with which of the following?

Impulsive behaviour. **Explanation:** **Bulimia Nervosa (BN)** is characterized by recurrent episodes of binge eating followed by inappropriate compensatory behaviors (purging, fasting, or excessive exercise). **Why Option A is Correct:** Patients with Bulimia Nervosa frequently exhibit **impulsive behavior** and poor impulse control. This is a high-yield association often tested in NEET-PG. BN is frequently comorbid with **Cluster B personality disorders** (especially Borderline Personality Disorder), substance abuse, self-harm, and shoplifting. Unlike Anorexia Nervosa (associated with high inhibitory control and perfectionism), Bulimia represents a "dyscontrol" pathology. **Why Other Options are Incorrect:** * **B. Obesity:** While patients with Binge Eating Disorder (BED) are often obese, patients with Bulimia Nervosa are typically of **normal weight or slightly overweight**. * **C. Metabolic Syndrome:** This is a complication of obesity and sedentary lifestyle, more commonly associated with BED or side effects of second-generation antipsychotics, rather than the purging cycles of BN. * **D. Amenorrhea:** This is a classic hallmark of **Anorexia Nervosa** (due to hypothalamic-pituitary-ovarian axis suppression from low body weight). In Bulimia, menstrual cycles are usually preserved, though they may be irregular. **High-Yield Clinical Pearls for NEET-PG:** * **Russell’s Sign:** Calluses on the knuckles from self-induced vomiting. * **Electrolyte Imbalance:** Hypokalemic hypochloremic metabolic alkalosis is the most common finding due to vomiting. * **Drug of Choice:** **Fluoxetine** (SSRI) is the only FDA-approved medication for BN (at a higher dose of 60mg). * **Contraindication:** **Bupropion** is strictly contraindicated in Bulimia due to an increased risk of seizures.

Q: Need for thinness despite being lean is a feature of which condition?

Anorexia nervosa. **Explanation:** The core psychopathology of **Anorexia Nervosa (AN)** is a morbid fear of obesity and a distorted body image. Patients maintain a relentless pursuit of thinness and a refusal to maintain a minimally normal body weight, even when they are significantly underweight or emaciated. This "need for thinness despite being lean" is the hallmark of the disorder, often accompanied by a "body image disturbance" where the patient perceives themselves as fat despite objective evidence to the contrary. **Analysis of Options:** * **Bulimia Nervosa:** While these patients are also over-concerned with weight and shape, they typically maintain a **normal or slightly above-normal weight**. The condition is characterized by binge eating followed by compensatory behaviors (purging). * **Metabolic Syndrome:** This is a cluster of physical conditions (hypertension, high blood sugar, excess body fat around the waist) that increase the risk of heart disease and stroke; it has no primary psychiatric component related to the "need for thinness." * **Binge Eating Disorder:** Patients experience episodes of losing control over eating but, unlike Bulimia, they do not engage in compensatory behaviors. These patients are often **overweight or obese** and do not typically exhibit the drive for thinness seen in AN. **High-Yield Clinical Pearls for NEET-PG:** * **DSM-5 Criteria for AN:** 1. Restriction of energy intake leading to significantly low body weight; 2. Intense fear of gaining weight; 3. Disturbance in the way one’s body weight/shape is experienced. * **Subtypes:** Restricting type and Binge-eating/purging type. * **Physical Signs:** Lanugo hair, bradycardia, hypotension, and amenorrhea (though amenorrhea is no longer a mandatory criterion in DSM-5). * **Russell’s Sign:** Calluses on the knuckles (seen in the purging subtype of AN and Bulimia).

Q: All of the following are features of Anorexia Nervosa except?

Amenorrhea is rare. **Explanation:** **Anorexia Nervosa (AN)** is a psychiatric disorder characterized by an intense fear of gaining weight, a distorted body image, and self-imposed starvation leading to significantly low body weight. **Why "Amenorrhea is rare" is the correct answer:** In the ICD-10 criteria for Anorexia Nervosa, **amenorrhea** (absence of at least three consecutive menstrual cycles) was a hallmark diagnostic feature in post-pubertal females. It occurs due to hypothalamic-pituitary-gonadal axis dysfunction triggered by low body fat and emotional stress. While DSM-5 removed amenorrhea as a mandatory diagnostic criterion to include males and those on contraceptives, it remains a **very common** clinical finding, not a rare one. **Analysis of other options:** * **A. Predominantly seen in females:** This is correct. The female-to-male ratio is approximately 10:1. * **B. Body Mass Index (BMI) is higher than normal:** This is **incorrect** (making the question technically have two false statements, but "Amenorrhea is rare" is the classic "except" choice in standard medical exams). In AN, BMI is characteristically **low** (typically <17.5 kg/m²). * **D. Malabsorption Syndrome:** While not the *cause* of AN, it is often a differential diagnosis. However, the question likely implies that the weight loss is due to voluntary restriction, not primary malabsorption. **NEET-PG High-Yield Pearls:** 1. **Two Types:** Restricting type and Binge-eating/purging type. 2. **Lanugo hair:** Fine, downy hair found on the body is a classic physical sign. 3. **Refeeding Syndrome:** The most dangerous complication during treatment, characterized by **Hypophosphatemia**. 4. **Russell’s Sign:** Calluses on knuckles from self-induced vomiting (more common in Bulimia). 5. **Treatment:** Family-based therapy (Maudsley approach) is the first-line for adolescents; SSRIs (Fluoxetine) are only effective *after* weight restoration.

Q: A mother presented her daughter with complaints that she has started behaving weirdly about her food habits for the last few months. She eats a lot of burgers in one go, and then she vomits it out. Her BMI is 27. What is the most probable diagnosis?

Bulimia nervosa. ***Bulimia nervosa***- Involves recurrent episodes of **binge eating** followed by inappropriate **compensatory behaviors** (like self-induced **vomiting**, excessive exercise, or laxative use).- Unlike **anorexia nervosa**, patients with bulimia nervosa typically maintain a body weight that is normal or overweight (BMI $\geq$ 18.5), which aligns with the given BMI of 27.*Anorexia nervosa*- The primary criterion requires the patient to have a weight that is significantly low for their age and height (e.g., BMI $\leq$ 17.5 in adults).- This diagnosis is excluded because the patient's BMI is 27, placing her in the **overweight** category.*Binge eating disorder*- Characterized by recurrent episodes of **binge eating** without inappropriate use of **compensatory behaviors** (purging).- This patient engages in **vomiting** after eating, which is a compensatory behavior that rules out a diagnosis of simple binge eating disorder.*OCD*- Involves the presence of **obsessions** (recurrent, intrusive thoughts) and/or **compulsions** (repetitive behaviors) that cause significant distress.- While eating disorders can feature obsessive elements, the core presentation of binging followed by compensatory purging is specific to **bulimia nervosa**, not Obsessive-Compulsive Disorder.

Q: Indoor management of anorexia nervosa is done on priority patients with:-

Weight for height less than 75% of normal. ***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.

Q: Which of the following disorders is more common in females?

Eating disorders. ***Eating disorders*** - **Eating disorders**, particularly **anorexia nervosa** and **bulimia nervosa**, are significantly more prevalent in females than in males, with female-to-male ratios ranging from **3:1 to 10:1**. - Sociocultural factors (body image expectations, media influence), biological factors (hormonal influences), and psychological vulnerabilities contribute to this **gender disparity**. - This is the **only option** in this list that is more common in females. *ADHD* - **Attention-deficit/hyperactivity disorder (ADHD)** is diagnosed more frequently in **males** than in females, with a male-to-female ratio of approximately **2:1 to 3:1** in childhood. - Although females with ADHD may present with more inattentive symptoms (which can be underdiagnosed), the overall prevalence remains higher in males. *Conduct disorder* - **Conduct disorder** is substantially more common in **males**, with a male-to-female ratio typically ranging from **2:1 to 4:1**. - Males tend to exhibit more overtly aggressive behaviors (physical aggression, property destruction), while females might present with more covert forms (relational aggression, rule-breaking). *Autism* - **Autism spectrum disorder (ASD)** is diagnosed more frequently in **males**, with a male-to-female ratio of approximately **4:1**. - This difference may be partly due to diagnostic biases and presentation differences, as females often present with less recognized or "camouflaged" symptoms and better social mimicry.

Q: Which of the following eating disorders is most common?

Binge eating disorder. ***Binge eating disorder*** **Binge eating disorder (BED)** is the **most common eating disorder**, with a lifetime prevalence of approximately 2-3% in the general population. It is characterized by: - Recurrent episodes of eating large quantities of food - A sense of lack of control during binge episodes - Significant distress following binge episodes - **Absence of regular compensatory behaviors** (unlike bulimia nervosa) *Bulimia Nervosa* **Bulimia nervosa** is less common than binge eating disorder, with a lifetime prevalence of approximately 1-1.5%. It is characterized by recurrent binge eating episodes followed by inappropriate compensatory behaviors (self-induced vomiting, laxative misuse, excessive exercise, or fasting). While bulimia is a significant public health concern, its prevalence is definitively lower than that of BED. *Anorexia nervosa* **Anorexia nervosa** is the least common of the major eating disorders, with a lifetime prevalence of approximately 0.3-1%. It is characterized by intense fear of weight gain, distorted body image, and severe food restriction leading to significantly low body weight. Despite its lower prevalence, anorexia nervosa has the **highest mortality rate** among all psychiatric disorders. *All have same prevalence* The prevalence rates of eating disorders vary significantly. Epidemiological studies consistently show that **binge eating disorder** has substantially higher prevalence than both bulimia nervosa and anorexia nervosa.

Q: Avoidance of food is seen in

Anorexia nervosa. ***Anorexia nervosa*** - Individuals with anorexia nervosa restrict their food intake significantly, often to the point of **starvation**, driven by an intense fear of gaining weight. - This eating disorder is characterized by a **distorted body image** where the person sees themselves as overweight even when severely underweight. - **Food avoidance and restriction** are the core features of this disorder. *Binge eating disorder* - This disorder is characterized by recurrent episodes of **eating unusually large amounts of food** in a short period, accompanied by a feeling of loss of control. - Unlike anorexia, there are no regular compensatory behaviors, and the primary issue is **overconsumption**, not avoidance. *Bulimia nervosa* - Bulimia nervosa involves recurrent episodes of **binge eating followed by compensatory behaviors** like self-induced vomiting, excessive exercise, or laxative misuse. - While there is concern about weight, the pattern is one of binging and purging, rather than consistent food avoidance. *Pica* - Pica involves **persistent eating of non-nutritive substances** (e.g., soil, chalk, paper) for at least one month. - This is not characterized by food avoidance, but rather inappropriate consumption of non-food items.

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

Decreased appetite. ***Decreased appetite*** - Patients with **anorexia nervosa** often experience a **normal or even increased appetite** but intentionally restrict food intake due to an intense fear of gaining weight. - The hallmark of the disorder is self-imposed starvation, not a physiological lack of hunger. *Avoidance of food* - **Avoidance of food** is a central feature of anorexia nervosa, driven by a pervasive **fear of weight gain** and a distorted body image. - Patients actively employ various strategies to **restrict their caloric intake**, including rigid dieting, skipping meals, and meticulously counting calories. *Purging episodes* - **Purging behaviors**, such as self-induced vomiting, misuse of laxatives, diuretics, or enemas, can be observed in the **binge-eating/purging type** of anorexia nervosa. - These behaviors are compensatory actions aimed at preventing weight gain after perceived overeating or even after consuming small amounts of food. *Significantly reduced weight* - A core diagnostic criterion for anorexia nervosa is a significantly **low body weight** for age, sex, developmental trajectory, and physical health, often defined as a body mass index (BMI) below 17.5 kg/m². - This weight loss is a direct consequence of the severe **food restriction** and compensatory behaviors.
