As humans our bodies are capable of informing us of things such as you’re hungry, not feeling well, feeling well, etc. The cells and organs play an important role in letting us know of our body’s signals. Something that your body probably tells you a lot is if you are hungry or not hungry. But how does your body let you “know,” when you are feeling hungry or not hungry?
Sugar is vital to our cells, and when we have an empty stomach a hormone known as ghrelin is released which is thus why we feel hunger. Responding to this hunger we will most likely eat something, and this food goes down our digestion system. This food is processed, broken down, and our body’s receive the nutrients. Once our stomach is full the ghrelin hormone is suppressed, which is why you feel full after a meal. If your bloodstream has an excess of sugar your pancreas may release some insulin which suppresses your appetite, or to make you feel not hungry. Thus this is how your body “knows,” when you are hungry/not hungry.
