Ghrelin is a multifaceted gut hormone which activates its receptor, growth hormone secretagogue receptor (GHS-R). Ghrelin's hallmark functions are its stimulatory effects on food intake, fat deposition and growth hormone release. Ghrelin is famously known as the “hunger hormone”.
What are 2 hunger hormones?

In regards to leptin resistance, bariatric surgery may have a big role in reducing its effects – by decreasing the hunger hormone ghrelin. Unlike leptin, ghrelin is actually produced in the stomach. During bariatric surgery, specifically laparoscopic sleeve gastrectomy, the size of the stomach is significantly reduced.

Does ghrelin grow back?
Right after surgery, the combination of swollen tissues and the difference in the amount of ghrelin being produced does often pretty much eliminate hunger and cravings. However, this won't be permanent. Tissues return to normal, and the reduced ghrelin becomes the new normal that your body adjusts to over time.
Where do I find leptin?
Leptin is produced by your body's fat cells. The more body fat they carry, the more leptin they produce ( 7 ). Leptin is carried by the bloodstream into your brain, where it sends a signal to the hypothalamus — the part that controls when and how much you eat ( 8 ).
