Weight Loss Surgery Ultimate 5

Question 1

Which hormone, primarily produced in the gastric fundus, is dramatically reduced after sleeve gastrectomy contributing to decreased hunger?

Accepted Answer

Ghrelin

Answer

Ghrelin, the hunger-stimulating hormone, is significantly reduced after sleeve gastrectomy because the fundus — its primary production site — is surgically removed.

Question 2

A patient 3 years post-gastric bypass regains 30% of their lost weight. What is the MOST common reason for long-term weight regain?

Accepted Answer

Return to pre-surgery eating habits and behaviors

Answer

Behavioral relapse to poor dietary habits is the most common cause of weight regain, as no surgery permanently prevents overeating in the long term.

Question 3

Which of the following best describes the biliopancreatic diversion with duodenal switch (BPD/DS)?

Accepted Answer

Combination of sleeve gastrectomy and significant small bowel bypass

Answer

BPD/DS combines a sleeve gastrectomy with a long-limb intestinal bypass, creating both restriction and profound malabsorption for maximum weight loss.

Question 4

What is the purpose of the 'liver-shrinking diet' required before bariatric surgery?

Accepted Answer

To shrink an enlarged fatty liver for safer surgical access

Answer

A high-protein, low-carbohydrate pre-op diet reduces glycogen and fat stored in the liver, making it smaller and easier for surgeons to retract safely during laparoscopic surgery.

Question 5

Which supplementation is specifically critical for gastric bypass patients to prevent Wernicke's encephalopathy?

Accepted Answer

Thiamine (Vitamin B1)

Answer

Thiamine deficiency can cause Wernicke's encephalopathy, a serious neurological emergency; it is particularly at risk post-bypass due to reduced absorption and frequent vomiting.
