What are gastrointestinal hormones?

Gastrointestinal hormones cover a wide array of chemicals produced in your stomach and intestines. These hormones help regulate hunger, digestion, fat storage and more. Taking advantage of modern advances in our understanding of how G.I. hormones interact with your body comprises one of the four pillars of Olumia Life.

Of particular importance to anyone looking to get in shape are the hormones peptide YY and the two incretin hormones, GLP-1 and GIP.

Peptide YY may be a strange name, but it’s an extremely important gastrointestinal hormone when it comes to your diet and overall health. Peptide YY is created by your small intestine and released into your bloodstream whenever you eat, especially with foods that are high in fat and/or protein. Your brain detects the level of peptide YY to know when you’re full and decreases how hungry you feel accordingly. Peptide YY also slows the speed at which you digest, causing you to, again, feel more full and less hungry.

See how this could be important to a diet? If the gastrointestinal hormone peptide YY is able to communicate properly with your brain, you’ll eat less while feeling more full. That’s a great 1-2 punch for your diet!

The other hormones mentioned, GLP-1 and GIP, are known together as incretin hormones. Incretins are only secreted in response to food. They send signals to your pancreas to release insulin into your bloodstream in advance of the rise in blood sugar that will happen later, as the glucose from food, carried by insulin to the cells in your body, is absorbed. This actually helps lower your blood sugar after a meal.

Incretins also slow the emptying of your stomach, so nutrient absorption is more efficient. When your stomach empties more slowly, you feel full sooner and your blood sugar doesn’t spike up as much, which in turn means you don’t need to pump out as much insulin to carry it away. (Check our answers to questions about insulin efficiency and insulin resistance to learn more about why this is so important.)

As you might expect, having good levels of incretin hormones has been proven to lead to weight loss.
