Will swallowing phlegm back hurt the body? Where does the phlegm go?

Although the phlegm is full of bacteria and other substances, but after being swallowed back, the phlegm will enter the stomach and intestines, and there is strong stomach acid in the stomach, these bacteria and dirty things can also set off a little wave in the respiratory system, and when it comes to the stomach, it is only decomposed by gastric acid and cannot resist, so under normal circumstances, you swallow the phlegm back, except that you will feel a little nauseous, it will not have much impact on the body.

When we are sick, the foreign bodies in the sputum increase greatly, and even contain some pathogenic bacteria. For example, if the mucous membrane of the respiratory tract is inflamed, the sputum becomes a battlefield after the human immune system fights microbes - which may contain inflammatory factors, inflammatory cells, immune cells killed in battle, pathogenic microorganisms, necrotic epithelial cells, etc.

Swallowing phlegm when you're sick: If you swallow coughed phlegm while you're sick, these germs can also enter your digestive system. Under normal circumstances, the number of such bacteria is small, and it will be sanitized by stomach acid and will not cause any effect on the body.

However, some bacteria, stomach acid can not be sanitized, such as active tuberculosis, then the sputum will contain Mycobacterium tuberculosis. If swallowed, Mycobacterium tuberculosis can enter the digestive system and may infect the gastrointestinal tract and cause intestinal tuberculosis.

In general, after swallowing, it will not have any adverse effects on human health. That's because the human stomach contains gastric acid, and we also know that gastric acid has a strong bactericidal and disinfecting effect, and there is no problem in killing these small bacteria in the sputum, so we don't need to worry. But it's better for us to develop good spitting habits, after all, swallowing phlegm can feel disgusting, and it's best not to do it because it's very unhygienic, so if people have phlegm in their mouths, it's best to wrap it in a tissue and throw it away.

Drinking plenty of water can dilute phlegm to a certain extent, making it easier to cough. Inhale and breathe briefly. This maximizes the distribution of inhaled gas in the lungs, increasing pressure in the airways and helping to cough up sputum.

Stoop. Bending over can increase intra-abdominal pressure, which can increase intra-abdominal pressure, causing a person to cough and produce high-velocity airflow.

It will definitely hurt the body in particular, and it will generally enter the respiratory tract. Very severe respiratory lesions may also occur, so it is best not to swallow.

There will be harm, and the phlegm that is swallowed back will enter the digestive system, and the phlegm itself is a special lot of bacteria, and if it enters the digestive system, it will infect the digestive system.

Of course it's harmful. It re-enters the digestive tract and destroys digestive enzymes and causes damage to the body.

Although phlegm is full of bacteria and other substances, after being swallowed, the phlegm will enter the stomach and intestines. There is strong gastric acid in the stomach, and these bacteria and dirty things can also make a little wave in the respiratory system, but when it comes to the stomach, it is only decomposed by gastric acid, and it can't resist, so under normal circumstances, if you swallow the phlegm back, in addition to feeling a little nauseous, it will not have much impact on the body.

Phlegm is originally a bacterium inside the human body, and if it is swallowed into the stomach again, it will absorb bacteria and toxins here, so when the phlegm chatters the bronchi, it will lead to the accumulation of bacteria, and when the bacteria on the bronchi accumulate too much, it will still enter the respiratory tract, causing secondary damage to the respiratory tract, and the cough will be more serious.
