Why do you scream when you re hungry?

Why are you hungry? It's the feeling of the nerve center. We have to eat every day, and the food we eat is usually emptied from the stomach after about 4-5 hours.

At this point, the stomach will begin to contract violently. The time it takes for the stomach to empty is closely related to the composition of the food. If it is purely sugary food, it usually takes about 2 hours to empty, protein food, about 3-4 hours, and pure fat food, about 5-6 hours.

Therefore, the average time to mix food is 4-5 hours. The rate at which the stomach empties is also directly proportional to the amount of food eaten. If there is 100 ml of chyme in the stomach, about 5 ml per minute will be excreted, and when the volume of chyme in the stomach reaches 500 ml, 15 ml per minute will be emptied.

Once the contents of the stomach are emptied, the stomach begins to contract. This is a more violent contraction that originates from the cardia and moves in the direction of the pylorus. This contraction makes the person feel hungry; That is, a signal that you should eat.

We know that there is always a certain amount of liquid and gas in the stomach at any given time. The liquid is generally the gastric digestive juice secreted by the gastric mucosa, and the amount is not too much. As for gas, it is usually swallowed along with food when eating.

In this way, these liquids and gases in the stomach, in the case of violent contraction of the stomach wall, will be squeezed and kneaded, running around, just like when we wash clothes, if a certain amount of air is wrapped in the clothes, rubbing and rubbing in the water, there will also be a sound of sucking and cooing, these two situations are the same reason.

It's physiological, it doesn't matter!

In addition to hunger, there are many causes of a rumbling stomach, such as irritable bowel syndrome. There are no parenchymal lesions in the gastrointestinal tract, but the function and flora are disordered, and various harmful bacteria ferment in the intestine to produce a large amount of gas, which expands the amplitude of intestinal peristalsis, resulting in intestinal hyperfunction, and intestinal sound. This bowel sound can be taken with intestinal probiotics to inhibit harmful bacteria and thus reduce symptoms.

Indigestion, eating foods that are difficult to digest or that produce gas easily (such as potatoes, sweet potatoes, milk, etc.), or when the stomach itself has a digestive disorder that causes intestinal microbes to break down and produce a large amount of gas, the stomach grunt is often heard. If a lactose intolerant person has diarrhea after drinking milk, the bowel movements will be accelerated, and the gurgling sound will be louder. If you don't want to increase the burden on your stomach, then it's better to eat less of these things in the future, and lactose intolerant people can choose lactose-free milk.

Intestinal obstruction, intestinal obstruction can be harmful, mild constipation, severe can be fatal. Obstruction makes the intestinal lumen continuously inhale air and accumulate a lot of gas and liquid, and the other is the gas produced by the decomposition and fermentation of intestinal flora, and the liquid is secreted by the intestine, and a large amount of gas and liquid will cause intestinal dilation and intestinal peristalsis, resulting in intestinal sound. If the intestinal obstruction is strengthened, the pressure in the intestinal lumen is too great, the venous return is blocked, the intestinal wall is congested and edema, and in severe cases, it can lead to intestinal ischemia and necrosis and perforation.

Gastrointestinal bleeding, in which bowel sounds are sudden and frequent, may indicate gastrointestinal bleeding. After gastrointestinal bleeding, blood enters the intestines, which exacerbates intestinal peristalsis, resulting in hypermorphosis of the intestines; If the bowel sounds are severe, accompanied by hemoptysis and hematochezia, it is necessary to go to the hospital as soon as possible**.

When the stomach and intestines are peristalsis and digested, the stomach will also bark. But in general, people with bowel sounds have a bad stomach, so you have to pay attention to your eating habits and eat less bananas, leeks and other things.

It is possible that the stomach growls because of hunger, but not all. If the food is not digestible or is too greasy, it will be transferred from the small intestine to the large intestine for digestion, and some gas will be produced in the process, and the stomach will growl.

There should be no problem, many people will, it should be just after eating the large intestine is moving, so it is always called.
