Food is not digested in the small intestine


Syndrome of insufficiency of digestion

Syndrome of insufficiency of digestion (syndrome maldigestii) is a symptom complex, arising at infringement of digestion of nutrition. Often it is combined with malabsorption syndrome.


There is a syndrome of digestive failure, diarrhea, flatulence. pain, burning and pouring in the stomach, belching and nausea. Flatulence occurs due to increased gas generation and disruption of the process of removing gases. Pain in the abdomen is caused by increased pressure in the intestines or as a result of spasms. In the latter case, they subsided after defecation. Often the syndrome of insufficiency of digestion is accompanied by loss of appetite and weight loss.


Syndrome of insufficiency of digestion is shown practically at any disease of a gastrointestinal tract. Moreover, either parietal digestion or cavity digestion can be disturbed. Pristenochnoe digestion is disrupted with a lack of intestinal enzymes and impaired adsorption of pancreatic enzymes. The cavity digestion is disturbed by the violation of the production of pancreatic enzymes, a deficiency of bile acids and a lack of hydrochloric acid and pepsin in the stomach. With such violations, food can not be properly digested, as it is impossible to properly break down proteins, fats and carbohydrates at various stages of digestion.

The syndrome of maldigestia can occur even without the reasons listed above. It can develop as a result of disruption of the peristalsis of the gastrointestinal tract. So, if the food moves too fast along the digestive tract, no matter how well the liver and pancreas work, it will not be able to digest. And if the food moves too slowly, then the intestinal microflora is more active than usual, involved in the digestion process, forming a large number of toxic substances that irritate the intestinal mucosa, thereby accelerating peristalsis intestines. This contributes to improper further digestion, fermentation, intoxication of the body.

Digestion in the stomach can be disturbed by gastritis. decompensated stenosis of the pylorus, stomach cancer. In the intestine, it can be disturbed by inflammatory diseases of the small intestine. Syndrome of insufficiency of digestion can develop at a diabetes. hyperthyroidism. Crohn's disease. diverticulosis of the intestine. The cause of this syndrome may be the use of antibiotics or cytostatics.


To diagnose the syndrome of inadequate digestion, a feces analysis is performed. which is usually detected by steatoreiu (fat in the feces). With the help of roentgenography, it is specified which part of the digestive tract is affected. To do this, a contrast agent study is performed. It is also necessary to do a clinical blood test. Analysis of urine. glucose tolerance test.


The main thing in the treatment of maldigestion syndrome is diet. It should be selected taking into account the stage at which the process of digestion of food is disturbed. But in any case, the food should be gentle, contain an increased amount of proteins and carbohydrates.

If digestion is disrupted due to disruption of the pancreas, enzyme preparations are prescribed.

If the cause of the violation of the liver, prescribe enzyme preparations and components of bile.

If the syndrome of maldigestia developed as a result of a violation of the peristalsis of the digestive tract, prescribe drugs to improve peristalsis.

Also prescribed drugs for the treatment of dysbiosis, which develops almost always with the syndrome of digestive failure.

For general strengthening of the body, vitamins and restorative products are recommended.


To prevent the syndrome of inadequate digestion, you must first and correctly and rationally eat. It is also necessary to comply with hygiene, and personal, and when cooking.

It is important to treat diseases of the gastrointestinal tract in a timely manner, such as gastritis, enteritis, liver and pancreas diseases.

Found an error?

Flatulence? Bloating? This is an insufficient digestion of food.

The causes of flatulence (bloating), as it may seem, a lot, but they all boil down to one.

The most common causes of flatulence (bloating) is usually considered:

1. The use of food, which in principle can not be fully digested (beans, cabbage, apples, dairy products with lactose intolerance, etc.);

2. Dysbacteriosis - development of abnormal intestinal microflora;

3. Diseases of the digestive system - inflammation of the small intestine, pancreas, liver, colon.

But let's look at these reasons a little more.

Wrong products.

With a specific food, everything is clear: if it can not in principle be successfully digested in the stomach, the small intestine is physically unable to draw all the nutrients out of it. These substances move into the large intestine, where they are awaited by microflora - various microorganisms, useful and not very, in this case it does not matter.

Microorganisms, faced with this generous gift, begin to actively develop resources, allocating carbon dioxide, causing bloating. It would not have happened if all the valuable nutrients had been absorbed into the small intestine. Microorganisms would only get hard to digest food fibers; they are not particularly roaming and gas formation would be moderate.


Therefore, dysbacteriosis in itself is impossible. If only intractable food fibers enter the intestine, the development of pathogenic microflora is difficult on them - it does not stand up to competition with the right microflora, which is ideal for feeding plant fibers is adjusted. The reason for the persistent development of abnormal microflora (and hence, bloating) isconstantingestion of poorly digested food.

Diseases of the digestive tract.

Diseases of the gastrointestinal tract are serious problems requiring treatment, but how exactly do they lead to flatulence? Dysfunction of the digestive system also leads to insufficient digestion, since the necessary enzymes are not isolated, or the food leaves the inflamed organ too quickly.

In the end, there are not really many reasons.

Thus, the cause of flatulence is always the same: the access of intestinal microflora to insufficiently digested food.

But why is the food not digested enough?

It's amazing, but the number one reason - our food is too good! And, to understand this, let us turn to the history of man as a biological species.

The diet, consisting mainly of plants, was used to a person during his formation as a species. By the way, these plants did not look the same as modern, past centuries-old selection and available now on the supermarket counter.

The prehistoric ancestors of man, thus, in the process of evolution, improved the digestive system, before in order to extract all nutrients from rough plant foods, which required a lot of time for digestion in stomach. Such a digestive system was left to the modern person practically without changes.

It should be?

The small intestine receives food rich in coarse plant components, thoroughly chewed, mixed mechanically in the stomach with acid, with gastric juice enzymes, in small portionswithin a few hours.

This is calculated and the organs involved in digestion in the small intestine: pancreas and gallbladder. Both bile and pancreatic enzymes should be excreted and mixed with food continuously in small portions for several hours, otherwise these organs workin the wrong mode.

A person after a meal feels a pleasant burst of energy, because the digestive system works evenly, without overload, and gives energy, and does not take away. The feeling of satiety at the same time lasts at least 3-4 hours, the food is digested completely and increased gas formation in the large intestine (and bloating) does not occur.

How is refined food digested?

The stomach, analyzing the composition of the contents contained in it, does not define in it dietary fibers that need a long digestion. The only program for which the digestive system is calculated can not be performed. But the other is not! Food is discharged from the stomach into the small intestine as is, and not in small portions, but at a time, which leads to a strong rumbling in the stomach after eating and flatulence.

The small intestine collides with a large mass of undigested food at a time, into which the pancreas and gall bladder simply can not immediately extract the necessary enzymes in such a volume. True, and without them readily available nutrients are quickly absorbed into the blood, which causes us weakness after eating and leads to a gradual deposition of fat.

These food masses were not subjected to long-term sterilizing action of stomach acid, and in fact the intestine carefully monitors their acid composition, since its task is to change the acid reaction to alkaline. If the acid reaction is initially not present at the entrance to the small intestine, then there is a risk of developing pathogenic microbes in it. This is a potentially very dangerous situation, so the small intestine tries as quickly as possible to pass through this mass of its incomprehensible composition.

Food does not have time to digest, does not becomea long-term energy sourcefor our body. Fast hunger appears, that if the situation repeats over and over again, leads to a systematic overeating and a set of excess weight.

And of course, to increased gas formation in the large intestine, bloating and flatulence.

How to prevent a problem?

In the usual diet, you need to make changes by addingto each mealplants containing dietary fibers, except those that your intestines do not tolerate. Apples, cabbage and legumes - it's better not to try. Correct food should be thoroughly chewed.

The process of forming a new food ration will not be fast, as the search for suitable products is not an easy task in the context of the ubiquitous abundance of refined food. But you can easily get rid of increased gas formation in the intestine (flatulence) by simply adding the correct dietary fiber to the diet.

What foods are not digested in the stomach, but in the duodenum?

leoPupil (91), closed 3 years ago

Nutritionists say that after 6 pm the stomach does not work and all food eaten after 18.00 remains in it until the morning, which is not good. Therefore, it is necessary before 6 pm. But products which bypassing the stomach are digested in the duodenum, you can use after 18.00. What are these products?

ewgeny gasnikovArtificial Intelligence (308991) 3 years ago

In the stomach, alas, nothing is digested, and-there is the splitting of foods with acids (gastric juice-a weak solution of hydrochloric acid and bile-a set of fatty
acids), in the duodenum-there is a splitting of these products by pancreas (weak alkali). Digestion of food, as correctly noted by the user ** kris **,
begins in the small intestine. YOUR dieticians, with their claims-ordinary fuckers, do not know the processes of digestion themselves and advise others.

Yeah, believe them. works the stomach after 18. just do not advise a heavy meal to eat-sleep the stomach will work slower.

BASIC food is digested in the small intestine - the longest (about 5 m) part of the digestive tract. In the small intestine, it is necessary to highlight the upper, the shortest part (27-30 cm) duodenum, for this small segment of the small intestine is one of the most important sites digestion of food.

Anatomically, the duodenum encompasses the pancreas in the form of a horseshoe - from the top right and below, at the level of the 12th thoracic and 2nd lumbar vertebrae. In the duodenum, gastric digestion passes into the intestinal. Gastric digestion, as you already know, prepares food for further digestion in the intestines.

In the duodenum, proteins, fats and carbohydrates that are ingested with food are brought to a state in which they can be absorbed into the bloodstream and enter the cells for further use. However, in the duodenum itself, absorption is very insignificant. It absorbs no more than 8% of digested food. The main absorption of digestion products occurs in the small intestine.

Food passes from the stomach to the duodenum in small portions - through the opening in the lower part a gatekeeper with a sphincter, or a closure device (it regulates the passage of the food mass into duodenum). The sphincter consists of annular muscles, which then contract, closing the opening, then relax, opening it.

When the acidic food gruel enters the pyloric part of the stomach, the acid contained in the food irritates the receptors present in its wall and the opening opens. A portion of acidic gruel passes from the stomach into the gut, in which, in the absence of food, the pH is alkaline (, ).

The passage of the food gruel into the gut continues until the contents of the duodenum become acidified. Then the hydrochloric acid, supplied with the food gruel into the duodenum, begins to irritate the receptors of its mucosa As a result, the sphincter closes and remains closed until the portion of food that has arrived is becomes alkaline.

The alkalization of the portion of the food gruel comes from the intestinal juice, which has an alkaline reaction. In addition, alkaline digestive pancreatic juice is involved in alkalization, playing an important role in the digestive process that occurs in the duodenum, as well as bile, coming from liver. After the alkalization of the portion of the food pulp arrived, the reaction in the duodenum returns to alkaline, and the sphincter re-opens, letting another portion of acidic food slurry from stomach.

This cyclicity in the work of the sphincter contributes to the fact that the enzymes of the intestinal juice that can work only in an alkaline medium, they periodically receive the opportunity to process each newly incoming portion food.

In addition to changing pH, the degree of filling of the duodenum plays a role in regulating the transition of food from the stomach to the intestine. If the walls of it are stretched by a food slurry, the sphincter closes, and the flow of new portions of food from the stomach stops. It is renewed only after the accumulated food passes further and the walls of the duodenum relax again. The process of digestion is, of course, disturbed. This is another point explaining why it is so harmful to overeat and why it is so important to eat a small amount of food in one sitting.

Digestion in the duodenum can occur only with the action of three types of digestive juices - intestinal, pancreatic and bile, produced by the liver. Under the influence of enzymes contained in these juices, proteins, fats and carbohydrates are digested.

Why such an emphasis on the duodenum? Did you like the name? The duodenum is the initial section of the small intestine.
And, the products can not get into the intestine, bypassing the stomach. And in the stomach - hydrochloric acid (chemistry passed?).

And yet, the opinion of nutritionists on food account after 18-00 radically diverge. Some believe that they do not eat at all, others - there are, but excluding certain products. Here's a tip from one:

- No bold products
After six in the evening, do not eat foods rich in fat. Prefer goulash something dietary, low-calorie. You can afford to eat a small portion of boiled chicken breast, combined with a light salad of fresh vegetables.

Do not flavor dishes with sour cream or mayonnaise. Take better soy sauce, but observe the measure, because it contains a large amount of salt.

- Fruit to fruits

At night you should not eat vegetables and fruits rich in organic acids, as they can provoke an increase in acidity and the appearance of heartburn, which is a very unpleasant condition.

In addition, you should refrain from eating foods with a lot of sugar. In particular, bananas or grapes - this is not the best food. It is desirable to refuse them.

- Not all macaroni are equally harmful

There is an opinion that pasta products negatively affect the figure. It should be noted that this is fundamentally wrong. Pasta, consisting of durum wheat, contains a small number of calories. In addition, the coarse plant fibers contained in such products will have a positive effect on the state of motility of the gastrointestinal tract.
