Is it harmful if half of the small intestine is removed? If there is anything!

The small intestine has the function of digestion and absorption, and the absorption of our nutrients is mainly through the gastrointestinal tract, where the small intestine plays an important role. The stomach is mainly a storage function, the large intestine is mainly to absorb water, and the absorption of nutrients is mainly to the small intestine, it is not related to the partial resection of the small intestine, but if most of it is removed, the small intestine is resected to 70, or the small intestine is less than 1 meter, then it will be fatal, nutrition can not be maintained, and it will lead to severe malnutrition.

It can even lead to the death of the patient.

In addition, the small intestine also has a very important role, which is often ignored by ordinary people, that is, our human digestive system, including the stomach and duodenum.

The small intestine itself produces a large amount of digestive juices every day, and this amount is about 8,000 to 10,000 ml.

It is the fluid produced by these organs themselves,99 which is reabsorbed in the small intestine, and if there is no small intestine, or if the small intestine cannot be reabsorbed, the patient will manifest as severe diarrhea, and the patient will soon die. It is a loss of blood volume. Therefore, such a patient, although his gastrointestinal tract is unobstructed, he may be able to eat something, but the loss of a large amount of digestive juice will quickly and directly endanger the patient's life.

There is no harm, the small intestine of the person is 5-6 meters long, and it is covered with folds, which increases the absorption area, and there should be no harm in removing half of it, but the absorption site has become smaller, at most the person will not be too fat.

Both the stomach and small intestine are digestive systems.

are used to digest food.

I'll be brief.

1.The main function of the stomach is to physically turn large pieces of food into small pieces through the peristalsis of the stomach, so as to facilitate the absorption of the small intestine, and at the same time, there is also gastric juice in the stomach for preliminary chemical digestion, but this chemical digestion is very limited, because of gastric acid.

The decomposition ability is not strong or the stomach acid is not sour enough (this is what everyone should have vomited, when vomiting, the mouth is sour, but not too sour).

2.The role of the small intestine is mainly chemical digestion, because the peristalsis ability of the small intestine is not as good as that of the stomach, but the digestion ability of intestinal juice is much stronger than that of gastric juice (or an example of vomiting, when you vomit a lot, then vomit out, there is bitter and astringent acid water, which is much more sour than when you first vomited, this is because it contains a certain amount of intestinal fluid).

3.It can be seen that the small intestine can replace the stomach to a certain extent, and when it becomes cancerous, the small intestine is used to recreate the stomach, because the digestion of the stomach is mainly a physical effect.

4.The stomach has a strong ability to move around, largely because the stomach is more elastic, like a balloon, which can be powerful.

It is small, but the elasticity of the small intestine is much worse, so after the operation, it is strictly forbidden to overeat!! Don't, be sure to eat something that is well digested and less greasy!!
