Weight Loss Weight Loss Medical 1 — Questions and Answers
Question 1: What BMI range is classified as 'obese' according to the CDC standards used in the United States?
- 25.0–29.9
- 30.0 and above (Correct answer)
- 18.5–24.9
- 20.0–25.0
Correct answer: 30.0 and above
The CDC classifies a BMI of 30.0 or higher as obese, with further classifications: Class I (30–34.9), Class II (35–39.9), and Class III (40+).
Question 2: Which FDA-approved medication class works by mimicking GLP-1 hormone to reduce appetite and is used for chronic weight management?
- Statins
- GLP-1 receptor agonists (e.g., semaglutide) (Correct answer)
- Beta-blockers
- Diuretics
Correct answer: GLP-1 receptor agonists (e.g., semaglutide)
GLP-1 receptor agonists like semaglutide (Wegovy) reduce appetite, slow gastric emptying, and promote significant weight loss and are FDA-approved for chronic weight management.
Question 3: What is metabolic syndrome and how does it relate to obesity and weight loss?
- A rare genetic disorder unrelated to weight
- A cluster of conditions (abdominal obesity, high BP, high blood sugar, abnormal lipids) that raise disease risk (Correct answer)
- A thyroid-only condition
- A type of eating disorder
Correct answer: A cluster of conditions (abdominal obesity, high BP, high blood sugar, abnormal lipids) that raise disease risk
Metabolic syndrome is a cluster of five risk factors linked to obesity, and weight loss of even 5–10% of body weight can significantly improve or reverse its components.
Question 4: Which surgical weight loss procedure restricts stomach size and reroutes part of the small intestine for enhanced weight loss?
- Gastric band
- Gastric sleeve only
- Roux-en-Y gastric bypass (Correct answer)
- Intragastric balloon
Correct answer: Roux-en-Y gastric bypass
Roux-en-Y gastric bypass both restricts stomach size and bypasses part of the small intestine, leading to greater average weight loss than restrictive procedures alone.
Question 5: What minimum percentage of body weight loss is considered clinically significant for improving obesity-related health conditions?
- 1–2%
- 5–10% (Correct answer)
- 20–25%
- 30%
Correct answer: 5–10%
A 5–10% reduction in body weight is considered clinically meaningful, producing significant improvements in blood pressure, blood sugar, cholesterol, and sleep apnea.
Question 6: Which thyroid condition can cause unexplained weight gain and make weight loss very difficult without medical treatment?
- Hyperthyroidism
- Hypothyroidism (Correct answer)
- Thyroid cancer
- Goiter alone
Correct answer: Hypothyroidism
Hypothyroidism (underactive thyroid) lowers metabolism by reducing thyroid hormone production, leading to fatigue, cold intolerance, and significant difficulty losing weight.
