Weight Loss Surgery Long-Term Outcomes and Follow-Up Care 1 — Questions and Answers
Question 1: What percentage of patients with type 2 diabetes typically experience remission or significant improvement after Roux-en-Y gastric bypass?
- 10–20%
- 30–40%
- 50–60%
- 70–80% (Correct answer)
Correct answer: 70–80%
Multiple studies show that 70–80% of type 2 diabetic patients experience complete remission or significant improvement after RYGB.
Question 2: How long should bariatric patients continue taking vitamin and mineral supplements after surgery?
- For 6 months until the body adjusts
- For 1–2 years until nutritional status normalizes
- For the rest of their lives (Correct answer)
- Only when blood tests show deficiencies
Correct answer: For the rest of their lives
Lifelong vitamin and mineral supplementation is mandatory after bariatric surgery due to permanent changes in digestion and absorption.
Question 3: Which comorbidity is LEAST likely to show improvement after bariatric surgery?
- Type 2 diabetes
- Obstructive sleep apnea
- Hypertension
- Established chronic kidney disease (CKD stage 4–5) (Correct answer)
Correct answer: Established chronic kidney disease (CKD stage 4–5)
Advanced chronic kidney disease often does not reverse with weight loss; bariatric surgery may slow progression but cannot restore lost kidney function.
Question 4: What is the expected average excess weight loss at 2 years after Roux-en-Y gastric bypass?
- 20–30% of excess body weight
- 40–50% of excess body weight
- 60–80% of excess body weight (Correct answer)
- 90–100% of excess body weight
Correct answer: 60–80% of excess body weight
RYGB typically achieves 60–80% excess weight loss at 2 years, making it one of the most effective long-term bariatric procedures.
Question 5: How frequently should bariatric patients have laboratory nutritional monitoring in the first year post-surgery?
- Once a year
- Every 6 months
- Every 3–6 months for the first year, then annually (Correct answer)
- Only when symptoms appear
Correct answer: Every 3–6 months for the first year, then annually
Quarterly to semi-annual lab monitoring in the first year detects deficiencies early before they cause clinical symptoms.
Question 6: Obstructive sleep apnea (OSA) is estimated to resolve or significantly improve in what percentage of bariatric surgery patients?
- 10–20%
- 30–40%
- 50–60%
- 80–85% (Correct answer)
Correct answer: 80–85%
Studies show OSA resolves or markedly improves in approximately 80–85% of bariatric patients following significant weight loss.
