Question 1

After a Roux-en-Y gastric bypass, which vitamin deficiency is most likely because its absorption depends on intrinsic factor and the bypassed duodenum?

Accepted Answer

Vitamin B12

Answer

B12 requires intrinsic factor and the bypassed portions of the stomach and duodenum, so deficiency is common after RYGB.

Question 2

What is the recommended minimum daily protein intake commonly advised for most post-bariatric patients?

Accepted Answer

60-80 g

Answer

Guidelines typically recommend 60-80 g of protein daily to preserve lean mass after surgery.

Question 3

Which mineral deficiency after bariatric surgery is a leading cause of anemia, especially in menstruating women?

Accepted Answer

Iron

Answer

Reduced acid and duodenal bypass impair iron absorption, making iron-deficiency anemia common.

Question 4

Why are chewable or liquid vitamin supplements often preferred in the early postoperative period?

Accepted Answer

They dissolve and absorb more reliably in the smaller stomach

Answer

Chewable and liquid forms dissolve more readily and absorb better while the stomach pouch heals.

Question 5

Dumping syndrome after gastric bypass is most commonly triggered by which type of food?

Accepted Answer

Simple sugars and refined carbohydrates

Answer

Rapid entry of simple sugars into the small intestine causes fluid shifts and dumping symptoms.
