The stomach is prepared to house and digest a large amount of food and has an escape route to the intestine. In addition, it is not he who commands: the brain is responsible for saying enough when it is time to stop.
Although we usually compare the stomach with a balloon, the way they both fill up is very different. In a balloon, a constant relationship between pressure and volume is maintained: the greater the first, the more the second increases. On the contrary, the size of the stomach does not only depend on the amount of food you eat. Actually, it is controlled by the nerves that surround it and by certain hormones.
When empty, this organ has a capacity of between 40 milliliters of liquid and almost 300 -not even the capacity of a conventional can of soda-. But once we start eating, its size can multiply to almost touch the two liters. Although we do not have to chew anything: just by salivating thinking of some delight we cause it to expand.
Another feature that differentiates it from a balloon or a balloon is the way its walls make holes. Far from stretching, what they do is unfold: at rest they form wrinkles or roughness that become smoothed as it expands … until it reaches a point where these folds do not give more than itself. Then, millions of nerve cells lining the stomach tell the brain that we are full through an electrical signal.
Equally important is chewing food very well so that the digestion of food is faster and more efficient otherwise, if your teeth are in bad condition do not expect your stomach perform the same functions with the same effectiveness, everything starts from mouth, that is why it is very important that visit your dentist in Tijuana for a general revision of your teeth.
However, both organs are not only understood through neuronal language, since they are also communicated in a chemical language. When the stomach is full, fat cells secrete leptin, a hormone that travels through the blood to signal the central nervous system.
In addition, the food takes about 10 to 15 minutes to pass into the intestine, with which the dilation of the stomach will depend more on how much you can swallow in that interval, how quickly you do it and a series of added factors such as age and the state of health and soul.
Although it is very difficult to happen, some cases have been documented of people who literally have eaten until their stomach has exploded. Of course, most people experience the feeling of satiety, or having spent with polvorones, when the stomach acquires a capacity of between 500 milliliters and a liter and a half.
Of course, if banquets and excesses become a habit and warnings are repeatedly ignored, the stomach can stretch to over two liters. Nobody hurts a good feast from time to time, but do not forget to listen to your brain when it warns you that the dessert is too much.
