Which serum marker should the CBE monitor annually to screen for iron-deficiency anemia after bariatric surgery?
Answer: Serum ferritin and complete blood count (CBC)
Serum ferritin reflects iron stores and, combined with CBC, allows early detection of iron-deficiency anemia, which is common after procedures that bypass the duodenum.
A male bariatric patient reports low energy, decreased libido, and depression 18 months post-surgery. Which hormonal deficiency should the CBE flag for evaluation?
Answer: Testosterone deficiency (hypogonadism)
Obesity-associated hypogonadism often improves but can persist post-bariatric surgery; low testosterone causes fatigue, low libido, and depression and should be evaluated.
What is the significance of monitoring thiamine (vitamin B1) levels in bariatric patients with persistent vomiting?
Answer: Thiamine deficiency can cause Wernicke's encephalopathy, a potentially fatal neurological condition
Persistent vomiting depletes thiamine rapidly, and because bariatric patients already absorb it poorly, deficiency can progress quickly to Wernicke's encephalopathy if not treated.
Which comorbidity typically takes the longest to fully resolve after bariatric surgery, if it resolves at all?
Answer: Osteoarthritis and degenerative joint disease
Osteoarthritis involves permanent cartilage degeneration that weight loss can slow or reduce in symptoms but cannot reverse, unlike metabolic conditions that often remit.
A bariatric patient with a history of kidney stones should be educated to limit which dietary component post-Roux-en-Y gastric bypass?
Answer: Oxalate-rich foods, due to increased intestinal oxalate absorption
After RYGB, fat malabsorption increases oxalate absorption in the colon, significantly raising urinary oxalate and the risk of calcium oxalate kidney stones.
When counseling a pre-diabetic bariatric patient preoperatively, what is the most important metabolic message the CBE should convey?
Answer: Surgery can induce remission, but lifelong dietary and activity habits are required to maintain it
While bariatric surgery powerfully improves insulin sensitivity and can induce pre-diabetes remission, long-term success depends on sustained lifestyle changes, not surgery alone.
