Weight Loss Surgery Question and Answers — Questions and Answers
Question 1: The most popular WLS is restrictive and malabsorptive, produces better long-term results than ABG, and has been shown to improve HTN, OSA, and DM.
- RYNGB (Correct answer)
- Duodenal switch
- nuva ring
Correct answer: RYNGB
RYNGB stands for Roux-en-Y Gastric Bypass, which is one of the most popular and effective weight loss surgeries. It is both restrictive (reduces stomach size) and malabsorptive (bypasses a portion of the small intestine), leading to significant and sustained weight loss. This procedure is well-documented for its excellent long-term results and its ability to resolve or significantly improve obesity-related comorbidities such as hypertension (HTN), obstructive sleep apnea (OSA), and type 2 diabetes mellitus (DM).
Question 2: Blood clots, infection, food aversion, undernutrition, vagus nerve injury with persistent nausea, gastroparesis, vomiting, and esophageal spasm/pain are possible side effects.
- Dumping syndrome
- Sleeve gastrectomy (Correct answer)
- Duodenal switch
- adjustable gastric banding
Correct answer: Sleeve gastrectomy
While many bariatric surgeries share general risks like blood clots and infection, the specific combination of vagus nerve injury, gastroparesis (delayed stomach emptying), and esophageal spasm/pain is more uniquely associated with sleeve gastrectomy. During this procedure, a large portion of the stomach is removed, which can sometimes impact the vagus nerve or alter stomach motility and function in ways that lead to these particular symptoms.
Question 3: An elevated BMI ______ is considered morbid obesity.
- Iron
- F
- B12
- 40 (Correct answer)
Correct answer: 40
According to widely accepted medical definitions, a Body Mass Index (BMI) of 40 or higher is classified as morbid obesity. This level of obesity is associated with a significantly increased risk of severe health complications and is a primary criterion for qualifying individuals for bariatric surgery. A BMI between 30 and 39.9 is generally classified as obesity, with various subcategories.
