When we eat, we often hear some restrained girls say, “Can’t eat any more, or the stomach will be stretched!”
Yes, many people think that our stomach is like a bad balloon. It is often blown up, it will become looser and even more dangerous. If you don’t blow it, the rubber will age, stomach. Will gradually shrink.
Is our stomach really as fragile as a balloon? First we need to understand the structure of the stomach.
Does long-term consumption or hunger change the stomach capacity?
Our stomach is a muscular organ, meaning that it is a house made up of muscles and several layers of muscle.
The innermost layer of the stomach wall is a variety of gastric gland cells, which can secrete gastric acid, proproteinase and some gastrointestinal hormones. There are intermuscular nerve plexuses between several layers of smooth muscle in the stomach wall, and the impulse of discharge is periodically performed to maintain the contraction of the stomach wall, so that the stomach is in a state of mild contraction at ordinary times. The stomach is slightly tubular when completely empty, with a capacity of about 50 mL. It is balloon-shaped when it is highly filled, and its capacity can reach 2L.
The stomach divides the pylorus, antrum, stomach, cardia, and stomach from top to bottom. But when we eat, even if we eat more food, most of them are limited to the antrum and lower part of the stomach. The other part is no food, mainly to relieve stress.
When we eat, the stomach will appear to be diastolic, that is, the volume of the stomach becomes larger, ready to contain food, while the secretion of glands in the stomach increases, the emptying is delayed, and the peristalsis is enhanced, so that the food is in the stomach. The mixture is fully mixed with gastric juice to form food into the chyme, and the protein is digested to some extent, so as to prepare for the absorption of the intestinal tract in the next step. Foods containing more carbohydrates stay in the stomach for a shorter period of time, while foods containing more protein and fat stay longer. Mixed foods generally have a gastric emptying time of 4 hours to 5 hours. This also determines the interval between our three meals.
When the food is emptied, the stomach returns to its original shape, and the intermuscular nerve plexus in the stomach wall continuously delivers a basic electrical impulse to maintain the stomach in a slightly contracted state.
Therefore, no matter whether it is often eaten or hungry, there is no problem of expanding or shrinking the stomach capacity. Because the shape of the stomach is different according to whether there is food or food, our stomach has very good stretching ability.
Often eating or hungry hurts the stomach
Even if you eat or hungry, your stomach capacity will not be stretched or hungry. But this does not mean that we can let our own diet, eat if you want to eat, and be hungry if you want to be hungry.
Relative to the shape of the stomach itself, we should pay more attention to the problem of gastric mucosa. Long-term consumption or hunger has a clear effect on the function of the gastric mucosa and stomach.
One of the main stimuli of our stomach to secrete gastric acid and pepsinogen is food, long-term hunger, lack of food stimulation, can lead to insufficient gastric acid secretion, affecting the digestion of food, and mucosal glands may shrink due to misuse, pay attention to Here is the atrophy of the mucosal glands, not the atrophy of the stomach itself.
At the same time, long-term hunger, due to lack of food stimulation, bile long-term retention of the gallbladder does not discharge, resulting in increased water absorption, prolonged exposure to gallstones .
When you eat it for a long time, it will obviously affect the emptying function of the stomach, and abdominal distension will occur . In the long run, it will lead to chronic gastritis , causing digestive function to decline.
In addition, if you eat too much at one time, there may be problems such as vomiting, acute stomach dilatation and even gastric perforation . Imagine the scene after the balloon is blown to the limit, and you know how terrible the consequences are!
In short, our stomach will not cause changes in capacity due to eating or hunger, but we should also try to avoid long-term eating or hunger, keep regular meals, you are good for the stomach, and the stomach is good for you.
