“That balloon you just saw? 👀
That’s 75–80% of your stomach… removed.”
But here’s what most people don’t realize—
That part of the stomach (the fundus) is where most of your ghrelin is produced.
Your hunger hormone.
Before surgery, ghrelin rises before meals and can stay elevated in people with obesity…
which is why hunger can feel constant, loud, and impossible to ignore.
After a sleeve?
Ghrelin levels drop significantly.
So patients don’t just eat less because they “should”…
they eat less because their biology finally gives them a break.
And that’s just one layer.
You also get:
• Faster gastric emptying → nutrients reach the intestine sooner
• Increased GLP-1 and PYY → better fullness + blood sugar control
• Improved insulin sensitivity → often before major weight loss even happens
This isn’t just a smaller stomach.
It’s a metabolic reset.
Not willpower.
Not discipline.
Physiology.
👉 If this changed how you think about surgery, save this.
