What are Causes of a Runny Nose?

Runny nose is most common in rhinitis, nasal polyps, and sinusitis. Common causes of runny nose include:

Runny nose

Runny nose is one of the common symptoms of nasal diseases. It can flow out through the anterior nostril and then into the nasopharynx. Those who flow into the nostril and spit out through the nasopharynx and mouth are called runny nose. There is only a small amount of mucus in the normal nasal cavity, which is moist to maintain normal physiological functions. Lesions in the nasal cavity can cause changes in the nature and amount of nasal secretions. A nasal discharge is called a runny nose.

Cause of runny nose

Runny nose is most common in rhinitis, nasal polyps, and sinusitis. Common causes of runny nose include:

1. Cold: The initial stage is watery or mucus, and pus may appear in the later stage of the cold.

2. Chronic rhinitis: Most of the nose is mucus. The amount can be more or less.

3, allergic rhinitis: clear water like snot, more volume, accompanied by sneezing, nasal itching, can be perennial or seasonal. Patients with allergic rhinitis can be accompanied by asthma, especially in children.

4. Chronic rhinosinusitis: mostly mucopurulent discharge, bilateral or unilateral, accompanied by nasal congestion, dizziness, decreased memory, etc. Unilateral sinusitis should consider odontogenic sinusitis.

5, nasal polyps can also appear runny nose, infection can be accompanied by purulent snot, nasal congestion, dizziness, memory loss and so on.

6, children's secretion is relatively strong, if there is no other discomfort, it may be caused by cold air to stimulate the nasal cavity, no special treatment is required. Unilateral nasal congestion with blood in the snot may be caused by foreign bodies in the nasal cavity.

7, yellow water-like secretions, to consider the possibility of cysts in the sinuses, take a sinus radiograph or CT.

8. Blood in the nose can refer to the common causes of nosebleeds.

9, other reasons also include cerebrospinal fluid nasal leakage, atrophic rhinitis, etc., the latter mainly dry nose, thick nose, less and stinky.

Runny nose caused by colds is well known. But why do some people often have a runny nose when they have a cold? A runny nose when you have a cold is called acute rhinitis. At this time, the nasal mucosa is congested and swollen, and the secretion of the glands increases. At first, it was watery, but it became pus after 3 to 5 days, and healed after 1 to 2 weeks. If acute rhinitis recurs, and the nasal mucosa becomes congested, swollen or even hypertrophic for a long time, that is chronic rhinitis, and the nose will often runny.

Ask your child to scoop out when there is a nasal discharge. To have the correct method of blowing your nose, press one side of your nostril and one side of your nose. At the same time, it is necessary to perform the nasal cavity unobstructed, otherwise the nasal discharge in the paranasal sinuses is not easy to exudate, and the pus in the nasal cavity can enter the paranasal sinuses or enter the eustachian tube to cause otitis media.

Intranasal infusion of vasoconstrictor drugs such as ephedrine can reduce nasal discharge, but patients with atrophic rhinitis cannot use such drugs. When dropping the medicine, prevent the medicine from flowing into the mouth. Because the child feels bitter taste, he will not let the medicine drop in the future. At the same time, in order for the liquid to drip evenly into the nasal cavity and not to flow out quickly, it is also necessary to have the correct posture for dropping the liquid. Paranasal sinusitis with excessive runny nose can be treated at the hospital for replacement therapy or puncture lavage.

Runny nose Chinese medicine cause of runny nose

Chinese medicine believes that there is a protective layer on the outside of the human body called Wei Qi. This Wei Qi is formed by the essence of food digested by the spleen and stomach, which protects the human body outside the human body. If the spleen and stomach are not good, then this protective layer will be unhealthy, and people will be vulnerable to external wind and cold.

As soon as the outside wind invades the human body, it causes the pores to close. As soon as the pores are closed, the water vapor originally emitted from the pores cannot be emitted normally. If there is no way to discharge it, it will squeeze onto the road of the respiratory tract. If it is too crowded, it will condense into a liquid. As a result, sputum is formed in the lungs and snot is formed in the nasal cavity.

Such confusion also causes the lungs to not flow down normally, and the water produced by the lungs cannot be transmitted to the bladder. Instead, they all stagnate to become burnt and become sputum and snot.

The treatment at this time should be to open the pores and let out the water and gas, and the sputum and snot will be fine. This is the cure. Usually, you need to strengthen the spleen, adjust the middle focus, and the spleen and stomach are good. The protective layer outside the body is strong, and this situation will not occur. This is the fundamental treatment. ^[1]

Runny nose clinical diagnosis

Runny nose properties, color, odor, mixture

1.Water-based

The secretion is thin and transparent like water. It is a mixture of vascular exudate and mucus, containing exfoliated epithelial cells, white blood cells, a small amount of red blood cells and mucin. Found in the early stages of vasomotor rhinitis, allergic rhinitis and acute rhinitis.

Mucus

The secretion is sticky, transparent like water, and contains a large amount of mucin. When normal people experience cold stimuli or emotional impulses in the nasal cavity, a large amount of mucus can be secreted by reflection. Common in chronic simple rhinitis.

3. Mucopurulent

A mixture of mucus and pus. Seen in the recovery period of acute rhinitis, chronic sinusitis.

4, purulent

More common in inflammation and bone, such as maxillary osteomyelitis, maxillary sinusitis, partial nasal foreign body and malignant tumor necrosis, are accompanied by varying degrees of malodor, fecal odor and other yellow-green secretions. Caseinous rhinitis and sinusitis often excrete dreg-like substances and have an odor.

5, bloody

Bloody or bloody secretions can be seen in nasal foreign bodies, nasal stones, fungal sinusitis, and are early symptoms of malignant tumors in the nose.

6.Cerebrospinal fluid rhinorrhea

Runny nose test item

1. General examination of nasal cavity

Pay attention to the color of the nasal cavity, turbinate, nasal passages, and olfactory sulcus. In acute rhinitis, the membrane is acutely congested with edema, and watery, mucus, and purulent secretions are present in the nasal passages. Chronic rhinitis with dark red and swollen mucous membranes and mucus in the nasal passages. Allergic rhinitis, vasomotor rhinitis, nasal mucosa pale pale purple gray. Acute and chronic sinusitis, pus in the middle nasal passage and olfactory sulcus.

2. Nasal and Sinus Endoscopy

Routine examination of the nasal cavity before or after the nose, the scope of examination of the nasal cavity is very limited. Many important parts of the nose, such as the openings of the sinuses, are located in narrow, concealed ditch or fossa and cannot be seen directly, which makes it difficult to judge the condition and clinical diagnosis. Endoscopy of the nose and sinuses. Except for the ethmoid sinus, all other sinuses can use this method to look directly into the sinus. The source of purulent secretions can be identified, and the fistula of the cerebrospinal fluid nasal leak can be diagnosed.

3.CT inspection

CT can check both the sinuses and the brain, so it is an important method for the diagnosis of deadly sinus diseases. To distinguish early benign and malignant lesions, CT values can be used to distinguish vascular, fat, necrosis, hemorrhage, cystic or calcified lesions, which is conducive to the analysis of the cause.

Runny nose

Runny nose

More common in the early stages of colds and patients with allergic rhinitis. However, patients with head trauma or nasal surgery should be careful of nasal leakage of cerebrospinal fluid if they suddenly leak watery fluid.

Runny nose white mucus

It is common in chronic rhinitis, and some physical and chemical substances in the living environment can also cause white mucus nose. Pygmy nasal discharge is common after a cold and cold. With the improvement of the cold, the purulent components in the mucopurulent snot will gradually decrease. If the duration of the disease is more than 10 days, the mucopurulent snot will still flow. The possibility of sinusitis should be considered.

Runny nose

Mostly caused by the rupture of serous cysts in the maxillary sinus, which manifested as intermittent outflow of yellow water on one side of the nasal cavity.

Runny nose

It is often caused by cheese rhinitis and has a foul odor. If it is green and has a special odor, it is a characteristic of atrophic rhinitis?

Runny nose

Mostly due to the inhalation of a large amount of black dust? Such as coal dust, smoke dust, metal dust, etc. mixed in the nose.

Judgment should be based on a comprehensive analysis of the nature, color, odor, mixed character, and findings of the runny nose.

Differential diagnosis of runny nose

Runny nose foreign body

Occurs in children under 5 years of age, but also in adults. The clinical manifestations vary depending on the size, nature, and duration of the foreign body. Common symptoms are one side nasal congestion, many secretions, and mucoid or mucopurulent. The foreign body stays for a long time, and the secretions can be bloody and have a foul odor.

Runny nose stone

Nose stone is a kind of stone with a foreign body as its core and surrounded by inorganic salts. Stones can be divided into exogenous and endogenous (blood clots, pus, etc.). Nose stones vary in size and shape and are mostly single. It occurs mostly in adults, with progressive nasal congestion on one side, watery, purulent, or purulent nasal discharge.

Runny nose

When there are ectopic teeth, extra teeth or retrograde teeth in the nasal cavity, they are called nasal teeth. Symptoms include obstruction of one side of the nose, bloody pus between pus and runny nose, and odor.

Runny nose chronic simple rhinitis

Chronic simple rhinitis is mostly vasomotor rhinitis, and the main symptoms are nasal congestion and increased nasal secretions. Nasal congestion is characterized by alternating and intermittent. Nasal discharge is often mucopurulent. It is mucopurulent when there is a secondary infection.

Runny nose acute sinusitis

Acute rhinosinusitis is a complication of acute rhinitis. In acute rhinitis, there are similar lesions in the sinus mucosa. As the nasal inflammation subsided, the sinus mucosa returned to normal. If 2 weeks after the onset of acute rhinitis, nasal congestion and mucus purulent nasal discharge become exacerbated, but accompanied by headache or facial pain.

Acute sinusitis is most common in the maxillary sinus, followed by the ethmoid sinus and frontal sinus. Often the sinuses in one side of the anterior group are simultaneously inflamed, but one sinus may be inflamed alone. The amount of runny nose discharge is related to the time of onset and body position; headache symptoms also vary. The symptoms of maxillary sinusitis are mild in the morning and severe in the afternoon; on the contrary, frontal sinusitis is severe in the morning and mild in the afternoon.

Runny nose chronic sinusitis

Chronic sinusitis is more common than acute cases, often secondary to repeated episodes of acute sinusitis. Inflammation can occur in a single sinus, but often in multiple sinuses or in the entire sinuses. Prolonged and severe purulent runny nose is characteristic. Runny nose is mucopurulent or purulent. If it is mucoid or jelly-like, it suggests an allergic nature.

Runny cheese rhinitis

Caseous rhinitis, also known as nasal cholecystoma, is characterized by the accumulation of foul cheese-like matter in the nasal cavity, which can erode soft tissues and bones over time, causing deformities inside and outside the nose. Lesions can also occur in the sinuses, called caseinous sinusitis. The main symptoms are progressive nasal obstruction, smelly serous secretions, a small amount of nosebleeds, and decreased smell.

Rhinorrhea vasomotor rhinitis

Vasomotor rhinitis is also called neuroreflex rhinitis, which means that the nasal mucosa is overreacting to certain stimulating factors. Runny nose and stuffy nose.

Runny nose allergic rhinitis

Allergic rhinitis is also called allergic rhinitis. Clinically, it is divided into two types according to its onset characteristics. One type has perennial onset without seasonality and is called perennial allergic rhinitis; the other type is seasonal onset and is called seasonal allergic rhinitis or hay fever. Perennial allergic rhinitis is more common in China. The disease mainly occurs in adolescents and adults, and clinical manifestations vary widely. Due to the long duration of exposure to allergens and the different response states of the body, symptoms can be mild or severe, and the duration of the attack can be long or short. Itching may occur suddenly in the nose, followed by continuous sneezing, and a lot of watery nose with tears. Itchy eyes and blocked nose on both sides.

Runny nose eosinophilic non-allergic rhinitis

Also known as non-allergic rhinitis with eosinophilia syndrome, it is a kind of perennial rhinitis with symptoms similar to those of perennial allergic rhinitis. The cause of the disease is unknown and has nothing to do with allergies. The clinical symptoms are similar to allergic rhinitis.

Runny nose necrotizing granulomatous

It is characterized by nasal ulceration that can extend to the face, mouth, and throat, causing extensive damage. Patients often die from major bleeding, sepsis, or systemic failure. Early symptoms are nasal congestion, drooling, or fluidic secretions, sometimes with blood.

Runny Nose Nasal Sinus Tumor

1. Nasal papilloma

The main symptoms are one side nasal obstruction, nosebleeds or blood purulent discharge, but also headaches, olfactory disorders and other symptoms.

2. Malignant tumors of the nasal cavity and sinuses

(1) Malignant tumor of the nasal cavity

Early nasal obstruction on one side. Bloody nose or nosebleeds. Advanced tumors invade the sinuses and orbits, showing the symptoms of sinus malignant tumors.

(2) Malignant tumor of the maxillary sinus

There are no obvious symptoms in the early stage, and occasionally blood in the nasal discharge occurs. When the maxillary sinus cancer originates from the upper wall, cheek numbness and pain may occur early. When it is located at the base of the maxillary sinus, toothache and looseness may occur, which is often misdiagnosed as dental disease.

Runny rhinomycosis

In the case of normal body resistance, the infection of molds generally has no clinical manifestations. Only in the case of low systemic resistance and the use of certain drugs, such as antibiotics and adrenal corticosteroids, molds that invade the human body begin to cause disease.

1.Aspergillosis

Aspergillus can invade mucosal arteries, causing thrombosis and ischemic necrosis of the tissue. Clinical manifestations are similar to chronic bacterial sinusitis, with nasal congestion, runny nose , and blood in the snot .

2. Mucormycosis

The nose is usually infected first, and later spreads to other organs. The disease is an acute, rapidly fatal disease, with typical inferior turbinate necrosis seen in the nose, black, and similar to a dry clot.

3. Rhinosporidiosis

Chronic granulomas can appear in the nasal cavity, shaped like polyps, brittle and sometimes misdiagnosed as nasal papilloma.

Runny nose cerebrospinal fluid rhinorrhea

Cerebrospinal fluid rhinorrhea can be divided into two categories, traumatic and non-traumatic.

1. Non-invasive injuries

(1) People with intracranial hypertension are usually caused by intracranial tumors, especially pituitary tumors.

(2) Those with normal intracranial pressure are mostly congenital abnormalities of the sieve plate or sphenoid region.

Traumatic

It often occurs in head trauma, skull base fracture with dural and arachnoid laceration. There are also sieve plate damage caused by intranasal surgery.

Cerebrospinal fluid rhinorrhea often manifests as unilateral, watery, intermittent or continuous. There is no mucus in the discharge, no precipitation, and it contains glucose.

Runny nose prevention

To prevent a runny nose, you must first prevent a cold. Colds are a common and frequently-occurring disease in life, but through reasonable measures, colds can be completely prevented.

1.Hot feet in hot water

Soak your feet for 15 minutes every night with hot water (the temperature is so hot that you can't bear it). Pay attention to the amount of water when you soak your feet so that your feet do not turn red after soaking to prevent colds.

2.Brine mouthwash

Rinse mouth with fresh saline every morning and evening and after meals to remove oral bacteria. When the flu is epidemic, you should pay more attention to mouthwash with saline. At this time, gargle with your head up to make the saline flush the throat better.

3.Cold water bath surface

Use cold water every day to wash your face, and wash your nostrils with a handful of water in your hand, that is, gently inhale a little water with your nostrils (be careful not to inhale too deeply to avoid pinching), and then scoop out repeatedly.

4. Massage the sulcus

Rub your hands against each other, and massage Yingxiang Point (located in the nasal sulcus, horizontal center of the outer edge of the nose) more than ten times after warming your palms, which can prevent colds and reduce the symptoms of nasal congestion after a cold.

5.Breathing steam

When you first catch a cold, pour boiling water into the cup, take a deep breath into the hot air, and the hot air will blow your face.

At the beginning of a cold, you can use a hair dryer to blow hot air into the temple for 3 to 5 minutes, several times a day, which can reduce symptoms and speed up recovery.

7 7 ways to keep your nose from running nose

Hot pack

Use a hot towel to apply a hot compress on your baby's nose.

Principle After the nasal mucosa contracts with heat, the nasal cavity will be relatively unobstructed, and the sticky snot will be easier to hydrate and flow out.

It is recommended that mothers keep their movements gentle during hot compresses! If you find nasal booger in your baby's nostrils, you can use a cotton swab dipped in water to clean it; you can also slowly massage your baby's nose or both sides of the nose.

2. Hot oil compress

Method Take the essential oil drops on a hot towel or a small handkerchief and apply it to the baby's nose; or spray the essential oil into the air.

Principle Some essential oils are used for hot compresses, which can improve the swelling of the nasal mucosa and help to open the nasal congestion. Essential oil sprays can improve the humidity of the air when the air is dry.

It is recommended not to use too much oil at a time. One drop is enough, because the concentration of the oil is too high, which will cause chemical irritation. In addition, do not use the oil spray indoors for too long, and pay attention to maintaining proper air humidity.

3.Dripping breast milk

Practice: Breastfeeding mother drips the squeezed breast milk into the baby's nostril.

The principle may have physical effects, because the warmth of breast milk can temporarily open the baby's nasal cavity, but there is no relevant medical evidence on whether it is related to the composition of breast milk.

Suggested use This method is a remedy and has not been scientifically proven.

4. Turn on the air conditioner

When the temperature drops and cold currents strike, you can turn on the stove to change the room temperature.

Principles Infants and children are particularly sensitive to external environmental and air stimuli. Therefore, when the temperature drops suddenly, it is easy to have symptoms of runny nose. When parents notice that the room temperature is low, they can turn on the stove to increase the room temperature and relieve the baby's nasal congestion Symptoms of nose.

It is recommended to use the stove for a moderate time to avoid the room temperature being too high, and the hot air will also dry the air. It is recommended that the mother can put a wet towel to maintain the humidity in the room.

5.Facial Steamer

Practice the steamer spray on the baby's face, contact the moisture and heat.

Principle Steam can moisten the baby's nasal cavity and quickly and naturally eliminate a large amount of nasal discharge.

It is recommended not to use the steamer too close to the baby, so as not to hurt his delicate skin; and it should not be used for too long, about 3 minutes.

Look at

Parents can judge the severity of their illness and increase their alertness based on their baby's appearance.

Active baby is debilitated and looks sick, always lying down, parents may need to pay attention!

Appetite babies can't eat, their looks are not good, or they may be caused by serious illness.

6. Raise your head

The practice is to spread a few small pillows under the mattress on the baby's head to make the mattress look like a smooth, 30-degree slide.

The principle is one of the temporarily assisted methods, but it does not cure the symptoms.

Suggested use Nasal congestion or runny nose can sometimes affect your baby's sleep. This method can only slightly relieve your baby's symptoms, but the effect is not long.

7. Nasal Aspirator

Electric methodWhen the baby's nose has a lot of secretions and the nasal sound is heavy, the mother can use a nasal suction device. When using it, pay attention to it. When sucking one nostril, press the other nostril at the same time.

How to determine if a runny nose is a cold or allergic rhinitis

Intervals between symptoms: Cold symptoms often occur after several days of exposure and exposure to the virus; allergic rhinitis occurs immediately after exposure to an allergen. For example, every time you clean the room, when the dust rises, you sneeze and runny nose, which means you may have allergic rhinitis.

Look at the sequence of symptoms : cold symptoms usually appear one by one, often starting with sore throat, then sneezing, and then runny nose, and it is less likely to cause itching of the eyes and throat. The typical symptoms of allergic rhinitis are sneezing, running nose, itching, nasal congestion, etc. in bed early in the morning, which can be alleviated after avoiding allergens, and patients often have a history to follow.

Look at the duration of symptoms : If the symptoms last more than 7 to 10 days, it may not be a cold. Note: This refers only to viral influenza and should not be confused with a bacterial upper respiratory infection (upper sensation).

Runny Double Heart Fur

Double-hearted fur, flowing two lines of blue color, looks like a runny nose, so flower buddies call it "running nose".

Plants of the genus Chirtita (known in China as Lactuca spp.), Cocoaceae, which is native to Sri Lanka, India, China, Southeast Asia and other places, is an annual or perennial herb.
