Why do I have nasal congestion when I have a cold, and why do I have nasal congestion when I have a

The cold is an infectious disease caused by a filtering virus, and its main lesion site is in the upper respiratory tract, so it is also called "upper respiratory tract infection" in medicine. The so-called upper respiratory tract includes the nose, throat, and trachea, which is the only way for gas to enter and exit the human body.

Our human nose is like a room with a door at the front and back, and there is a nasal septum in the middle that divides it into two rooms, left and right, and on the side wall of each room hang three curly turbinates, this house is called the nasal cavity. The front of the nasal cavity is connected to the outside world through the nostrils, and the back part leads to the pharynx. The pharynx is a cavity behind the nose and mouth, and it is a communication artery for breathing and swallowing.

There are many nasal hairs growing in the nostrils, and there is a mucous membrane with cilia and extremely rich capillaries on the surface of the nasal cavity, and the nasal mucosa often secretes a small amount of mucus, or nasal mucus, to clean the inhaled air.

When you have a cold, the nasal mucosa becomes inflamed, the tissues swell, the capillaries dilate, and the secretions increase, which hinders the flow of gases in and out, and the nose is naturally not easy to ventilate. It's like a passage that wasn't wide and it's full of things, and of course the entry and exit can't be smooth.

Hello, don't worry, this is a normal symptom of a cold, blood vessels congestion and edema when you have a cold, tissue fluid exudation, and the outflow of tissue fluid accumulates in the nose, which causes nasal congestion, so don't worry, take some medicine, take good conditioning, and it will be fine in a week

A cold is also called an upper respiratory tract infection, which includes the nose, pharynx, larynx, bronchi, etc. When the nasal mucosa is infected and becomes red and swollen, mucus is released to block the airway, so nasal congestion occurs.

0 colds are not terrible, meow meow to support.

It is said that about 50% of colds are caused by rhinovirus, and the nasopharynx is the site of the initial infection, so nasal congestion is a common symptom after a cold, but it doesn't matter if you eat some crack or something, I just like that.

After nasal congestion, breath-holding is used, and when it is uncomfortable, it will widen the nasal cavity due to the body's protective mechanism.

After a cold, the nasal throat will become inflamed, and the sinuses will enlarge, and the nostrils will be blocked, and the nose will be congested.

The cold is a gradual process, generally when attacked, there will be an incubation period of 1-3 days, when the capillaries of the nasal mucosa, through the action of nerve reflexes, the blood vessels constrict, and the secretion of mucosal glands is reduced.

In the early stages of a cold, the nose may feel dry, burning, or itchy, and often sneeze. Then it will reflexively cause nerve excitation, so that the blood vessels and lymphatic vessels in the mucosa will dilate, the glands will enlarge, the turbinate mucosa will be congested and swollen, and the secretions will increase, so that the air in and out will be obstructed, and the nose will not breathe.

A cold is an upper respiratory tract infection. It can be divided into viral infections (such as upper respiratory tract infections caused by influenza virus, adenovirus, rhinovirus, etc.) and bacterial infections (such as bacterial pharyngeal tonsillitis).

Among them, viruses are mostly caused by rhinovirus, parainfluenza virus (not the same as influenza virus), respiratory syncytial virus, echovirus, coxsackievirus, coronavirus, adenovirus, etc. The clinical symptoms are nasal congestion, sneezing, runny nose, fever, cough, headache, etc., which are mostly self-limited. Although it is more common in winter and spring, there will be no pandemic.

This is specifically due to the fact that the cold is a contagious disease caused by a viral infection, and the key is in the respiratory tract, and the upper respiratory tract is the nose and throat. The key reason is that the respiratory tract is the only way for the vapor to enter the body, so if you have a cold, it is the nose that is the first to be disturbed.

The nasal cavity of the nose of the body is connected to the outside according to the nasal cavity, and the throat is the part of the nose and the back of the inside of the mouth, which is only very important.

Generally, it often refers to a cold infected by a virus**. Most of them are caused by viral infections such as cold viruses and rhinoviruses. As for why the nose is blocked during the process of cold, the mechanism is mainly like this, the viral infection invades the human body and invades the columnar microvillous squamous epithelial cells of the patient's respiratory tract, and subsequently, causes inflammation in the body.

That is, your body detects that a small virus is attacking you, and then encourages the white blood cell count in the blood night to fight the viral infection.

In that case, your white blood cell count needs to run from your capillaries to your nasal cavity, and when the white blood cell count comes down from the capillaries, there will also be liquid extravasation (you can temporarily understand that the water in the capillaries is also carried out when the white blood cell count is out). This is why in the case of a cold, there will be a lot of runny nose, which will cause the patient's nose to become blocked.

Not all cold patients should drink more water! When you have a cold, you not only need to drink water, but you also need to drink more water, which seems to have become an unshakable basic common sense in everyone's thinking. Not all people with colds who drink more water are good for their condition.

Drinking a lot of water for a cold is likely to lead to hypernatremia. Surveys report that when a person's respiratory tract suffers from a sensation, such as a cold or acute bronchitis, the body exudes a lot of water-retaining soluble male hormones. When the levels of these chemicals are high, drinking a lot of water can cause overcapacity of water and an imbalance in the body's electrolyte solution, leading to hypernatremia.

You can't drink more water when you have a cold, just for these cold patients with respiratory tract symptoms, not all cold patients are like this.

1. What is the cause of nasal congestion in colds, which mainly causes upper respiratory tract infections after viral infections. After a cold, the virus will invade the nasal mucosa, causing lesions of the nasal mucosa, and edema and exudation of the nasal mucosa.

2. When the nasal mucosa is diseased, symptoms such as nasal congestion and runny nose will appear. If the symptoms are severe, you need to go to the hospital for examination.

3. It is recommended that if the patient has such symptoms, he should go to the relevant hospital as soon as possible and ask a professional doctor for diagnosis and treatment to avoid delaying the condition.

Because when you have a cold, your nose is prone to secreting some secretions, so you get nasal congestion when you catch a cold.

There are two main causes of nasal congestion caused by colds, one is nasal congestion caused by nasal discharge, and the other is caused by congestion and swelling of the nasal mucosa. This is because respiratory infections are usually present during a cold, which can cause congestion and swelling of the nasal mucosa.

Maimaru knows you're doing this now, right?So why do you have nasal congestion when you have a cold?When we catch a cold, due to the invasion of viruses or bacteria, the nasal mucosa becomes inflamed, and the surrounding capillaries dilate, causing the nasal mucosa to become congested and swollen, and at the same time, it will secrete a large amount of fluid (that is, nasal discharge), making the nasal space that is not spacious smaller and smaller

Since the nasal cycle is controlled by the autonomic nervous system (ANS), our subjective consciousness does not control it.

Acute inflammatory lesions of the nasal mucosa caused mainly by viral infection. When the body's immunity and resistance are reduced, the defense function of the nasal mucosa will be destroyed, the virus will be transmitted through the respiratory tract and enter the body, and the bacteria latent in the upper respiratory tract will also multiply and multiply, and the toxins will be stronger.

If you feel nasal congestion as soon as you catch a cold, this is because when you have a cold, the body's immunity prevents germs from entering the body, and nasal discharge will appear.

The main reason is that if you have a cold, you will have nasal discharge, and if the nose is blocked, it will cause nasal congestion.

It is because after a cold, it will cause problems with the nasal mucosa, which leads to this feeling of nasal congestion.

The increase in the volume of the lining of the nasal cavity impedes air flow, as if the same number of vehicles are driving smoothly on a wide road, but are prone to traffic jams on narrow roads. This is the reason why the nose is not breathing when you have a cold. In cold environments, the nasal mucosa becomes larger in order to better heat the inhaled air.

Nasal congestion after inflammation of a cold is becauseDilation of small blood vessels in the nasal mucosa causes mucosal congestion and edemaThe increase in the volume of the lining of the nasal cavity impedes air flow, as if the same number of vehicles are driving smoothly on a wide road, but are prone to traffic jams on narrow roads. This is the reason why the nose is not breathing when you have a cold.

The symptoms of a cold are:

Inflammation of the nasal discharge. Within 15 minutes of entering the body, the nasal congestion rhinovirus attacks the epithelial cells of the respiratory tract. Naturally, the attacked cells will not sit idly by, and will immediately secrete many signal molecules to report to the human body that "there is an enemy invasion". At this time, the body's immune system responds, a process called "inflammation".

When the "battlefield" of inflammation spreads to the nasal cavity, the cells of the nasal mucosa are attacked by the virus and secrete more fluid, which is called nasal discharge. This is the reason for the long runny nose when you have a cold. At the beginning of a cold, the nasal discharge is clear and clear, but as the disease progresses, the nasal discharge begins to contain more protein and becomes thicker and thicker.

If there is a bacterial infection after a cold, the corpse of the white blood cells fighting the bacteria will be expelled along with the nasal discharge, and the nasal mucus will become yellow-green purulent discharge. After a cold and inflammation, the dilation of small blood vessels in the nasal mucosa causes mucosal congestion and edema, and the increase in the volume of the nasal lining obstructs air flow. This is the reason why the nose is not breathing when you have a cold.

In a cold environment, the nasal mucosa will become larger in order to better heat the inhaled air, so the nasal congestion will be more severe when it is cold; On the contrary, a warm environment will make nasal congestion lessen. When nasal congestion is severe, the doctor will spray drugs into the nasal cavity to make the nasal cavity unblocked, so that the nasal mucosa vasoconstriction, edema is reduced, secretion is reduced, and the nasal congestion and runny nose are improved.

Because the lungs are open to the nose, typhoid fever and the sun meridian, the cold evil first invades the lungs, and headache, nasal congestion and runny nose will appear.
