AP PSYCHOLOGY

Detailed explanation-1: -Your stomach releases ghrelin when it’s empty to signal your brain that it’s time to eat. Ghrelin is often called the hunger hormone, but it does more than control hunger. It also signals your pituitary gland to release growth hormones, plays a role in insulin release and protects your cardiovascular health.

Detailed explanation-2: -Ghrelin is a hormone that increases appetite. It is released by your stomach, and travels throughyour blood to sginal to your hypothalamus that your body is in need of fuel, as well as to conserve energy and find food. Typically, ghrelin is released when your stomach is empty.

Detailed explanation-3: -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”.

Detailed explanation-4: -Ghrelin, which is produced by the stomach, increases during periods of fasting or under conditions associated with negative energy balance such as starvation or anorexia. In contrast, ghrelin levels are low after eating or with hyperglycemia, and in obesity.

Detailed explanation-5: -Levels of ghrelin increase when fasting (in line with increased hunger) and are lower in individuals with a higher body weight compared with lean individuals, which suggests ghrelin could be involved in the long-term regulation of body weight. Eating reduces concentrations of ghrelin.
