1

For whom does the NIH recommend bariatric surgery?

People with BMI >40 or BMI >35 with significant co-morbidities.

2

2 categories of bariatric surgery?

Restrictive (stapling, lap-band, etc.)
Malabsorptive (duodenal switch, bypass, etc.)

3

How does Roux-en-Y gastric bypass work: What's connected to what?

Small gastric pouch made, connected down to jejunum.
Pancreatic stuff flows into jejunum as well.

4

What's the duodenal switch operation?

Gastric sleeve resection, then
Duodenum kept, but brought down to distal jejunum (most of jejunum is bypassed).

5

Where did the gastric sleeve resection come from?

Came from the duodenal switch operation being done in 2 parts- but people realized that the gastric sleeve itself worked pretty well.

6

What hormonal reason likely makes the gastric sleeve resection extra effective?

Ghrelin (pro-hunger hormone) is produced in the fundus of the stomach - if that's removed, there's less drive to eat.

7

How long, roughly, does it take glucose levels to normalize after gastric bypass?

Days to weeks - not long at all.
(it cures and prevents type 2 diabetes)

8

Do people with bariatric surgery tend to live longer?

Yes, about 7 years longer.

9

Effect of bariatric surgery on cancer rates?

Reduces cancer risk in women, but not in men.

10

Is bariatric surgery safer than a cholecystectomy?
Is it cost effective?

Yep.
Yes, at less than $50,000/QALY.
