Stomach – an extremely flexible body


The stomach is an important organ of the digestive system, it is a muscular sack, which is about 15-30 cm long and about 12-14 cm wide. The maximum capacity of the stomach of a healthy person is about 2 liters of fluid – the stretching of its walls occurs when we overeat too much. 

The basic role of the stomach is the digestion of proteins contained in the diet, as well as the processing of food into a homogeneous, fragmented mass, which is susceptible to the action of enzymes in the duodenum. The stomach secretes gastric juice containing digestive enzymes. To better understand how this body works and why it is so flexible, let’s take a closer look at its structure.

Structure of the stomach 

The stomach has a slightly bent shape, bulging to the left. When it is filled with food it is more like a balloon. During hunger, the stomach is in a solar plexus. After eating a meal, it lightly bulges towards the left hypochamp. The bag-shaped organ can hold up to about 2 liters of fluid combined with the shredded food. In obese people this organ is excessively stretched, therefore some people are recommended to reduce it. 

The stomach consists of the bottom located at the esophagus, the stipe and the pylorus, which lies close to the duodenum. The place where the esophagus was connected to the stomach was defined as a groove. The muscle of the sphincter shrinks and relaxes, allowing more portions of crushed food into the stomach. If it works properly, the stomach contents do not regress into the esophagus. When such a pathology occurs, the patient is diagnosed with gastro-oesophageal reflux, commonly known as heartburn. At the end of the stomach there is a pylorus responsible for the proper functioning of the gastrointestinal tract. Thanks to its proper functioning, the digested food is moved from the duodenum to the small intestine and does not regress. 

The mucous membrane of the stomach covering it from the inside has a pleated surface covered with villi and gastric bypasses. In the small depressions there are the mouths of the glands producing hydrochloric acid and pepsin digesting proteins. Their mixture is referred to as gastric juice. The gastric mucosa also consists of proteins – how does it happen that the stomach juice does not damage it anyway? It is protected by two factors. 

Pepsynę is produced by the body in the form of a pepsinogen, which is its inactive precursor. It is activated only under the influence of hydrochloric acid. The second factor preventing damage to the mucous membrane is the tight adherence of cell membrane cells forming a specific protective coating. However, it sometimes happens that one of the mentioned factors fails – then the gastric fluid causes erosions in the mucous membrane. After some time, they turn into stomach ulcers. 

Digest food in the stomach 

From the outside, the stomach is covered with a serous membrane. Between the membrane and the stomach wall is muscular. After movement of the food swollen up by the saliva into the organ in question, it begins to shrink and relax rhythmically. Then the food is fragmented and moves towards the duodenum. The liquid food is then mixed with the gastric juice. After mechanical treatment time for chemical treatment. Properly digested food gets into the duodenum, where it is waiting for him further enzymes decomposing nutrients into prime factors. 

5 meals a day – a method for reducing the stomach 

Too stretched stomach can be very simple – people with a very stretched stomach usually have problems with overweight and obesity. In addition, they can eat a lot of products at one go. The problem of stretched stomach is obese and suffering from a compulsive overeating syndrome. 

People who want to quickly reduce their weight and at the same time reduce the volume of the stomach use the method of consuming five small meals a day. However, it does not always bring satisfactory results. Some people require surgical treatment, but these are very rare cases. 

The effects of overeating 

The stomach can increase its volume up to five times as a result of stretching. The stomach does not inform you that it is already full – information about it is first sent to the brain. As a result, from the time of filling the stomach to the feeling of fullness, it takes about 10-15 minutes. It is very easy, therefore, to extend this organ, especially at the fast pace of eating. This significantly affects the tendency to gain weight – most people eat more than they should. The stomach should have the size of two joined fists. This should also be a portion of one meal. By following this rule after a meal there will be no heaviness on the stomach. Also, excessive sleepiness will not occur – the characteristic effect of consuming too large meals. 

Surgical methods of reducing the stomach 

A too stretched stomach can be appropriately minimized by surgical treatment. Modern medicine uses at least several methods of surgical reduction of the stomach. These are techniques such as 

– stitching the stomach with staplers (mechanical stitches) 

– putting on a silicone band 

– excision of part of the stomach 

These are operations with risk of complications. They are not performed routinely. The patient must meet the criteria for such procedures. 


A life size stomach has the size of two joined fists. As a result, overeating can increase the volume up to five times, which is a straight way to obesity. You can restore the natural size of the stomach by eating small meals 4-5 times a day, as well as by accurate and slow biting and chewing the food – but this requires sacrifices. It is very difficult to at first start to overripe – this is how the change in the volume of the meal is perceived by the body. The hardest thing to do is leave the table when you do not feel the blissful feeling of being full. However, strong will and work on yourself bring very fruitful results – lightness of figure and power of energy every day.
