4hw.com.cn: when we eat, we often hear some restrained girls say 'no more, or the stomach will be enlarged! 'then will the stomach really be enlarged
Yes, many people think that our stomach is like a poor balloon. If we blow it often, it will become more and more loose, and even there is a risk of explosion. If we don't blow it all the time, the rubber will age, and the stomach will gradually shrink.
Is our stomach really as fragile as a balloon? First we need to understand the structure of the stomach.
Can long-term eat full or hunger change gastric capacity?
Our stomach is a muscular organ, which means that it is a house of muscles, and it has several layers of muscles.
The innermost layer of gastric wall is a variety of gastric gland cells, which can secrete gastric acid, proteasome and some gastrointestinal hormones. There is an intermuscular nerve plexus between several layers of smooth muscle in the gastric wall, which has been periodically releasing electrical impulses to maintain the contraction of the gastric wall, so that the stomach is in a state of mild contraction at ordinary times. When the stomach is completely empty, it is slightly tubular, with a capacity of about 50ml. When it is highly filled, it is spherical, with a capacity of up to 2L.
The stomach is divided into the pyloric part, antrum part, body part, cardia part and stomach bottom from top to bottom, but in fact, when we eat, even if we eat more food, most of it is only limited in antrum part and the lower part of stomach body, and other parts are without food, mainly to relieve the pressure.
When we eat, the stomach will have receptive relaxation, that is, the volume of the stomach becomes larger, so as to prepare for the food. At the same time, the secretion of glands in the stomach increases, the evacuation is delayed, and the peristalsis is enhanced, so as to make the food fully mix with the gastric juice in the stomach, form the food into chyme, digest the protein to a certain extent, and prepare for the next absorption in the intestine. The time of gastric emptying for foods with more carbohydrates is shorter, while for foods with more protein and fat, the time of gastric emptying for mixed foods is generally 4-5 hours. This determines the interval between our meals.
When the food is emptied, the stomach returns to its original shape. The muscular nerve plexus in the stomach wall continuously sends out basic electric impulses to maintain the stomach in a slightly contracted state.
So no matter how often we eat or starve, there is no problem of enlarging or reducing the capacity of the stomach. Because the shape of the stomach depends on whether there is food and how much food there is. Our stomach has a very good stretching ability.
It hurts your stomach to eat too much or starve too often
Even if the stomach is full or hungry, it will not be full or shrink. But that doesn't mean we can let our own food go, eat it if we want, and starve if we want.
Compared with the shape of the stomach itself, we should pay more attention to the problem of gastric mucosa. Long term support or starvation has a definite effect on gastric mucosa and gastric function.
One of the main stimulations for our stomach to secrete gastric acid and pepsinogen is food. Long term hunger and lack of food stimulation will lead to insufficient gastric acid secretion and affect the digestion of food. At the same time, due to the loss of mucosal glands, atrophy may occur. Note that here is the atrophy of mucosal glands, not the atrophy of the stomach itself.
At the same time, long-term hunger, due to the lack of food stimulation, bile remained in the gallbladder for a long time, resulting in increased water absorption, which is easy to lead to gallstones for a long time.
When you eat for a long time, it will obviously affect the emptying function of the stomach, resulting in abdominal distention. In the long run, it will lead to chronic gastritis, resulting in the decline of digestive function.
In addition, if you eat too much at one time, you may have problems such as vomiting, acute gastric expansion or even gastric perforation. Imagine the scene when the balloon is blown to the limit, and you will know how terrible the consequences are!
In a word, our stomach will not change its capacity due to overeating or starvation, but we should also try to avoid long-term overeating or starvation, and keep regular three meals. If you are good to your stomach, your stomach will be good to you.
