Is it that if you eat too much, your stomach will gradually get bigger, and if you eat less, your stomach will gradually get smaller? Is the bigger the belly, the bigger the appetite, and vice versa? Today we will find out the answer.
Before answering the above questions, we can first understand why the stomach is different in size. The fattest part of the stomach is the gastric sac. Everyone's stomach pouch is different in size, but miraculously, the stomach capacity of adults is the same and will not change. Of course, it is not that the stomach volume has not changed, but that the stomach will return to its original state. For example, under normal circumstances, the stomach capacity is only 100 ml, but when people are full, the stomach capacity will increase to 1200 to 1600 ml, but no matter how much the stomach capacity changes at this time, the stomach capacity will return to its original state when the digestive function plays a role.
So there is no difference in the size of the stomach we talk about in life, because we are talking about the capacity of the stomach. So, why do you feel better after "overeating"? This may be a psychological suggestion or a habit. Anyway, it's not the stomach.
If people feel that their stomachs are getting smaller after eating less, it is also because of psychological hints and habits. Sometimes, every meal is eaten less and less, and this state continues to become a habit, so it is easy to have the illusion that your stomach is small and you can't eat any more.
After eating, food will enter the stomach through the esophagus, the stomach wall will be elastic, the volume will gradually become larger, and the stomach wall will gradually become thinner. If you eat a lot of food every day, the stomach is often in an expanding state, which will weaken its telescopic function, and the stomach wall is easy to relax on an empty stomach, so more food is needed to make the stomach wall produce the same tension. More exaggeratedly, if the stomach continues to expand, it is no longer a question of whether the stomach can expand, but will affect health and even life. The stomach will press the diaphragm and even the heart and lungs upward, causing them a great burden and squeezing blood vessels and nerves.
Therefore, it is necessary to control the diet rhythm at ordinary times, and don't overeat or lose weight frequently, which will be very unfavorable for the self-repair of the stomach. A "eater" can treat himself once in a while to relax himself in a tired life, but he can't always be in a state of eating.
