Why can I still digest food after gastrectomy?

The function of the stomach is mainly to digest food, and digestion and absorption can be said to be the basic guarantee of human survival. However, we usually see that some patients are still able to eat as normal after their stomach has been removed. If a person has no stomach, can the food after eating still be digested in the body?

Experiments and actual results have shown that even without a stomach, digestive activities can still be carried out. Because of this, food can still be digested even after part or even all of the stomach has been removed.

The digestion of food is very complex, and the stomach plays an important role. Doctors have taken this into account when performing gastrectomy surgery and will preserve as much of the residual stomach as possible if it is not a serious stomach cancer. Generally, cut off about 2 3, and then connect the stomach and intestines.

It is true that the stomach plays an important role in the digestive system and plays the most important role in digestive activities, and it is based on this that when doctors do gastrectomy surgery, they will keep as much residual stomach as possible according to the condition, and only cut off 2 3 at most, which is called gastric resection surgery in medicine.

If you have severe stomach cancer and need to remove all of your stomach, your digestion will be affected to a certain extent, but it can still be carried out. Because it is not only the stomach that can digest food in the human body, the role of the stomach is mainly in "grinding" coarse food and secreting part of the digestive enzymes, and the initial digestion of food, and many important digestive enzymes are secreted by organs such as the liver and pancreas, and the absorption of nutrients is also mainly carried out in the small intestine.

Of course, after the stomach is removed, the structure of the stomach changes, and the normal physiological function of the stomach is affected, and there are often poor stomach intake, postprandial fullness, and digestive and absorption disorders. Therefore, for patients with gastric removal, post-operative dietary care is very important.

Total gastrectomy is a relatively large operation. The loss of function of the stomach after a total gastrectomy will greatly reduce the digestive function. This function will compensate other parts, but it should be done gradually, and attention should be paid to the conditioning of life:

1. You should eat less and more meals, eat a little less at each meal, eat a few more meals, because the stomach has no ability to accept it, you can't digest it if you eat too much, and it is easy to cause acid reflux and vomiting. 2. Proper exercise can increase intestinal peristalsis, thereby promoting emptying and reducing the patient's symptoms. 3. The content of eating is mainly soft food and liquid food, which is easier to digest and easier to empty.

After the gastric resection is complete, it loses its dependence, and the stomach is non-renewable, so the patient must have a strong will to survive and actively cooperate after the gastrectomy.

Total gastrectomy is a relatively large operation, when the stomach is removed, the function of the stomach is completely lost, resulting in a decline in digestive function, so it is recommended that patients should eat small and frequent meals in the diet, so as to achieve gradually.

Eat small meals frequently, do it step by step, exercise properly after meals, effectively promote intestinal peristalsis, and choose soft and easily digestible food.

If you want to take care of yourself, try not to eat some greasy things, eat more vegetables and fruits, and try to eat some liquid food.

After gastric resection, food will be digested and absorbed through the small intestine, and normal people also absorb food nutrients through the small intestine. The digestion process of food is very complex and does not play a big role. Doctors have taken this into account when performing unresected surgery, if it is not a serious stomach disorder.

Will be kept as much as possible. The stomach and intestines are generally about two-thirds, and then the stomach and intestines are removed, and after the stomach is partially removed, it will grow again in a few years to almost the same size as before.

The stomach is an enlarged part of the esophagus that is located under the diaphragm, connecting to the esophagus and leading to the small intestine. Stir the food by peristalsis so that the food is well mixed with the gastric juices. The stomach of an animal is generally commonly known as "belly", such as: pig belly, cow belly.

The stomach wall of mammals is generally composed of 3 layers of tissue, the inner layer is the mucosal layer, the outer layer is the serous layer, and the middle layer is the gastric gland, which generally has 3 types: cardia glands, pyloric glands and oxyntic glands. The first two are found in the cardia and pyloric regions, respectively, and both secrete mucus.

Oxyntic glands are mainly found in the mucosa of the gastric body and fundus, and are straightened duct glands, and the lumen of about 3 7 glands is discharged into a small pit on the surface of the gastric mucosa, with about 90 100 small pit per square millimeter of mucosa. There are three types of cells in the oxyntic glands, namely main cells, parietal cells and mucus cells, in addition to secreting water and inorganic salts, each cell has its own special secretions: the main cells secrete pepsinogen, the parietal cells secrete hydrochloric acid and intrinsic factors, and the mucus cells secrete mucus.

The stomach is innervated by sympathetic and parasympathetic nerves. The sympathetic nerve comes from the celiac ganglia, the parasympathetic nerve is the vagus nerve, and the stomach is rich in blood vessels and lymphatic vessels.

The function of the stomach is to use gastric acid and bile to crush and mix food fully, and the absorption of nutrients is completed in the small intestine and large intestine, so people who have had a gastrectomy can absorb nutrients as long as they eat liquid food and other crushed foods on their diet.

The stomach is not the only digestive organ, the small intestine can also play a role in digestion, as long as the food eaten is easy to digest and absorb, there is no problem.

The intestine can also be absorbed, simple sugars and amino acids can be directly absorbed, and the stomach mainly decomposes proteins and polysaccharides, so the stomach can be digested after being removed.

After the stomach is removed, there are other digestive systems in digestion, and after the stomach is removed, the amount of food is small, and you can only eat liquids.

Because the stomach is not the only digestive organ of the human body, both the large and small intestines can help digest food.

The main function of the stomach is to break down food, and if you don't have a stomach, you can eat some foods that are easy to decompose by yourself and rely on the intestines to absorb nutrients.

The stomach can be regenerated, as long as it is not completely removed, it will grow back.

There are many digestive organs in people, and the most important digestive organ is the small intestine, and the stomach is actually much worse, but most people know about the stomach.

Then you are an organ that can regenerate, it has the ability to regenerate, it grows little by little. You have your stomach removed, and you're able to eat a little bit at first, and then help with digestion. After growing up little by little, it was another one in order to be the same as before, because digestion is not digested by the stomach alone, and the location is a tool used to store food in Lae, is it suitable for digestion?

Mmmm, another organ to help with digestion.

I'm not the only digestive organ, I still have a spleen to digest after the removal.

The cow seems to have four stomachs or two.

Yes, but not the entire stomach.

The digestion of food is very complex, and the stomach plays an important role. Doctors have taken this into account when performing gastrectomy surgery and will preserve as much of the residual stomach as possible if it is not a serious stomach cancer. Generally, cut off about 2 3, and then connect the stomach and intestines.

In this way, after partial gastric resection, the residual stomach will "regenerate" and grow in a few years, reaching almost the same size as before, and has little effect on digesting food. If the stomach is completely cut, it will definitely affect digestion. However, the role of the stomach is mainly in "grinding" coarse food and secreting some digestive enzymes, and many digestive enzymes are secreted by the liver and pancreas, which are mainly absorbed in the small intestine.

Therefore, even if the stomach is completely cut off, as long as liquid or thin semi-liquid food is eaten, it can still be digested and absorbed in the small intestine.

Answer: After gastrectomy, you can first use a straw to eat liquid food, and when the stomach returns to normal, you can eat normally, and the food enters the intestine directly from the oral esophagus and is directly absorbed through the intestine.

The main function of the stomach is to hold food and be able to store food in large quantities.

After gastrectomy, the person eats the same as a normal person, except that he eats liquid food and high protein in the early stage, and can eat normally in the later stage, and he can digest food normally.

People who have had a gastrectomy should eat smaller, more frequent meals. Eat some foods that are easy to digest and can't eat raw, cold, and hard foods. Of course he can digest food.

Normally, you can still digest food, but it may be partially reduced in functionality, and the diet is mainly soft and easy to digest, and proper cooking of millet porridge is also very nourishing to the stomach.
