What is the Hormone Ghrelin? Part 1
Ghrelin is a hormone that is produced in the stomach. It is known as the “hunger hormone” because it plays a role in regulating appetite. Ghrelin levels increase when the stomach is empty and decrease when the stomach is full.
Ghrelin has also been shown to stimulate the release of growth hormone from the pituitary gland. Growth hormone is important for the growth and development of the body. Ghrelin levels are highest during periods of growth, such as childhood and adolescence.

Ghrelin levels are also increased during times of stress. This is thought to be due to the fact that ghrelin increases the body’s production of cortisol, a stress hormone.
Ghrelin levels are decreased by eating, exercise, and some medications. For example, antacids and proton-pump inhibitors (PPIs) decrease ghrelin levels.
Ghrelin has many functions in the body, but its exact role is still not fully understood. More research is needed to determine the full extent of the hormone’s effects.
