What is the cause of sudden bleeding from the nose without any symptoms?

Hello this friend! Nosebleeds are a symptom that can be pathological or non-pathological. Then the most common cause is a local problem, such as bleeding due to the rupture of the local mucosa.

Bleeding from mucosal rupture is usually related to dry nose caused by fire. The second is nasal polyp bleeding. The third is to check whether there are any blood diseases, which may be caused by thrombocytopenia, and defects in coagulation factors can also cause bleeding.

In addition, nasal telangiectasia can cause bleeding. Therefore, if there is a nosebleed, it is necessary to find out the cause of the bleeding and go to the hospital for an examination.

What causes frequent nosebleeds in the summer.

Hello, the main cause of allergic rhinitis is related to the individual's allergic constitution, as well as repeated contact with related common allergic factors in the environment, such as insect mites, pollen, dust, paint, milk, peanuts, seafood and other foods. First of all, we must identify the specific allergens through the determination of allergens and avoid contact in a targeted manner, and then we must actively carry out the anti-allergic drug Bidanin in the acute attack period, and the third is to actively control and prevent **, avoid colds, and long-term nasal irrigation with normal saline will help improve the microenvironment and reduce. Wishing you good health!

Raising otters requires the construction of a breeding room, with an area and a pool of 3 1m, equipped with a wooden production box (1, leaving a small hole, and laying hay in the box. Outside the small area is a concrete floor with a barbed wire fence (3 m high).

Feeding management. Generally, the fence is adopted, and the cement ground sports field in the open air is surrounded by a fence with a height of 3m barbed wire. There are 3 6 swimming pools on the sports field, and the pools should be equipped with clean water.

The sports field is connected to a small breeding room with an area of 2 1 m high pool. The indoor also needs to be a high wooden production box, the specification is 1, the production box is covered with a high observation hole, and the box is lined with hay.

The otters can be weaned 40-0 days after birth, but after weaning, they should be caught in another pond and raised, with a density of 8-9 in each pond. Otters grow faster and can reach annual body weight after 1 year. Under the conditions of captivity, the feed of otters is mainly fresh freshwater trash fish, each of which is fed every day, and a small amount of animal meat residue, offal, grains, vegetables, etc.

In cold weather, feed standards need to be increased by 25%. In the summer, when the temperature is high, you can feed some small fish, loaches, frogs and green feed. Adult otters are fed 3 times a day and twice a day in winter.

Juvenile otters are fed 4 times a day, and freshwater trash fish can be fed, or fresh fish can be replaced with rice, minced meat, and fishmeal. Male and female otters should be kept separately during the non-breeding period, and during the breeding period, the male otters should be caught in the female otter pond for mating. Otters are easy to domesticate, domesticated otters can hear people's call to it, and take food from people's hands, it is known that the former Soviet Union's Moscow Zoo has carried out experiments on dry-raised otters, young otters from a young age, and refuse to enter the water when they grow up.

To do physical exercise, getting up and running every morning helps to strengthen the body's physique and strengthen the body's immunity. Massage the sides of the nose with your hands to help promote blood circulation; Beware of colds, which can also be easily triggered. Maintenance is well-givingTwin Talk

The daily diet should be light, do not eat spicy food, and eat less fishy foods such as fish and shrimp, which is the main method of daily care.

Black holes form inside stars, leading to the destruction of stars.

There are still many unclear points about this supernova, and research is still ongoing. A supernova is a supernova explosion that occurs from a star with a mass of more than 25 times the mass of the Sun, and is 10 times brighter than a supernova explosion of a star with a mass of 8 25 times the mass of the Sun.

Energy. A supernova explosion occurs on a star with a mass greater than 25 times the mass of the Sun. They are even brighter than ordinary supernovae, 10 times brighter. Theoretical research predicts that supernovae will emit intense rays, that is, "ray bursts."

Theoretical studies have shown that when a star with a mass of more than 25 times the mass of the Sun collapses, a black hole forms inside it. If the black hole rotates at high speed, the stellar material that is sucked in will form a disk and eject a powerful jet that will break through the star, which is called a large explosion.

Formation.. How can a black hole that only inhales matter blow matter away and explode? Studies have shown that supernovae are a phenomenon that occurs when a black hole formed inside a star rotates violently. The spinning black hole is swept up in stellar material, forming a disk around it.

The material that is so violently stirred and rotated is subjected to the stellar magnetic field, and as a result, a powerful jet is ejected outward. This jet breaks through the star, and it becomes a big explosion.

Dark supernovae.

In another case, the black hole that forms inside the star rotates only slowly, and although the star also emits a weak jet, almost all of the stellar material is sucked into the black hole. This burst is called a faint supernova.

Study. A supernova explosion occurs on a star with a mass greater than 25 times the mass of the Sun. They are less than 1% brighter than supernovae and not even as bright as ordinary supernovae.

At this point, a large amount of stellar material is inhaled, so only a relatively weak explosion occurs.

Mass star.

According to theoretical analysis, stars with masses of 140,300 times the mass of the Sun are very unstable and will eventually erupt and leave nothing. In 2010, scientists discovered a supergiant star with a mass of 320 times the sun in the spider nebula in the Great Magellanic Guardian system, named R136A1, which is extremely unstable and does not live long, and humans can expect to see it collapse and produce powerful gamma-ray bursts in the next million years.

First of all, we can eat more foods high in copper, such as bran, tahini, spinach, rape, Chinese cabbage, celery, lentils, potatoes, fish, shrimp and soy products, etc. Daily careGrace Danin

And you can also eat some foods rich in zinc, such as pork liver, pork kidney, lean meat, etc., and fish, seaweed, oysters, clams, etc. are also very good.

Hard-shelled fruits are peanuts, walnuts, chestnuts, etc., which can be eaten, especially oysters, which have the highest zinc content, with an average zinc content of 100 mg per 100 grams.

There are three kinds of glazed surfaces of Yuan blue and white:

a) Shadow blue glaze.

Also known as green and white glaze, it was used on blue and white in the early and middle Yuan Dynasty, with domestic green materials. The blue and white glaze of blue and white porcelain in the late Yuan Dynasty is a derivative of the shadow blue glaze, which is different from the shadow blue glaze or green and white glaze of the early and middle Yuan Dynasty. The glaze is graying or yellowing, and the glaze layer has a strong luster, or it is matte, which is related to the high proportion of glaze ash in the glaze layer in addition to the lack of firing technology.

The blue and white porcelain of the Yuan Dynasty is glazed with blue and white glaze, which is smooth and transparent, and the fine skin shell layer can be seen on the surface of the fetal bone, and the glaze is not smooth, and there is a sense of unevenness when you hold it with your hand. The body tire glaze is slightly flashing blue, slightly light blue in the warmth, in addition to the water green of the foot ring, the body tire glaze often shows light tooth yellow, sometimes milky white, its color will be slightly different with the change of humidity and temperature in the air. In the Yuan period, blue and white vases and jars, oblique light through the tire glaze will slightly show irregular off-white silk stripes, also known as glaze decoration.

There are no bubbles on the underglaze blue and white in the Yuan period, and the tire glaze is dry when the temperature is high, but sometimes there will be faint sweating. The color of the glaze in the Yuan period seems to have a sense of activity.

b) White glaze. It has been used since the middle of the 14th century to the Zheng period, using imported green materials. The glaze is white and blue, the glaze is smooth and translucent, smooth and moisturizing, the glaze is blue, the brightness of the glaze often flashes, and the glaze of the foot ring shows a faint water green. With just the right amount of transparency, brightness and color, it can better set off the expressiveness of blue and white.

c) Egg white glaze.

At the end of the Yuan Dynasty, blue and white began to be used, the glaze layer was cloudy, and domestic green materials were used, and many small vessels were used, with goblets, bowls, bowls, and small pots in the majority, and the outer ring of these utensils often left finger marks left by hand when soaking glaze. In addition to the jade pot spring vase utensils, the bottom of the Yuan blue and white is generally unglazed. There are glaze spots of different sizes and shapes at the bottom of the exposed tires.

There is a ring of glaze marks of varying width near the bottom of the high foot on the inside of the goblet. Plum bottles and other thin bottles have a plain tire along the inner side of the mouth. The inner wall of the large jar is glazed by the glaze method.

The inside of the lid is plain, light earthy yellow, with fine glaze spots. The glaze surface of the Yuan blue and white ware is basically flat, and the glaze surface of the large cutter is slightly convex at the bonding place of the carcass, and the glaze thickness of the mouth is uneven, and the glaze is beige in the thin place. From the point of view of the remnants, there is no glaze in the belly of the vessel below the neck of the bottle, and the bottom of the bottle and jar or the foot of the goblet and bowl are common with pieces of glaze spots, and each glaze spot is surrounded by light-colored flint red edges around the foot and the glaze.

Some of the edges of the utensils have burrs (i.e., small bubbles bursting). The glaze on the surface of the vessel has the phenomenon of glaze shrinkage, which is not serious and belongs to a small number of phenomena. The glaze feels warm and moist like jade, and the light is soft and not dazzling, if it is too bright or has strong light highlights, it is worth considering.

Many people often have sudden nosebleeds in the summer, which excludes organic lesions, and dry air and drinking less water are the main causes of nosebleeds. Nosebleeds in summer are associated with exertion, exercise. Nosebleeds should often eat foods that cool blood, nourish yin, and clear heat, and lotus root is a better choice.

Lotus root has a high iron content and is rich in vitamin K, which has the effect of constricting blood vessels and stopping bleeding. Therefore, if you often have nosebleeds, eating some lotus root can not only achieve the purpose of clearing the fire, but also play a role in replenishing blood and stopping bleeding.

It may also be caused by changes in the structure of the nasal cavity (deviated septum), nasal inflammation such as sinusitis, chronic rhinitis, and benign tumors. Sudden nosebleeds without warning, or bleeding that is not easy to stop, should be vigilant and timely checked, ** the primary disease.

Nosebleeds are also associated with exertion, exercise, etc. Young people, in particular, love sports, and often when they are exercising, their nose suddenly bleeds.

In general, these bleeding symptoms can be stopped by the patient on his own. However, if there is no warning, it is best to go to the hospital for a check-up if you have a sudden nosebleed to rule out lesions such as nasal tumors as soon as possible.

In case of nosebleeds, the nose can be blocked with a tampon ball, and the head can be leaned forward normally in order to stop the bleeding as soon as possible. At the same time, a cool towel can be applied to the forehead or nose to lower the temperature of the head and nose to reduce the symptoms of bleeding. If there is too much bleeding in the nasal cavity that is difficult to stop, you should see a doctor in time.

There are many causes of nosebleeds, including nasal trauma, scabs on the mucous membranes, damage from foreign bodies such as acids and alkalis, excessive sun exposure, and excessive alcohol consumption. Frequent nosebleeds are a complication of the cardiovascular system, internal organs, various infections, blood disorders, and other diseases. Many ** nosebleeds are often thought to be a problem with the nose itself, which is actually a bit of a headache doctors, and frequent nosebleeds should be diagnosed dialectically.

Traditional Chinese medicine believes that nosebleeds are caused by the reversal of qi and blood in people. The nose belongs to the lung orifice, and the appearance of diseases in the nose is generally related to the abnormality of the lungs and liver. When a person's qi and blood rise, especially when the lung qi is hot, a person will have nosebleeds.

When the lung qi is too hot, the fundus of the person's eyes will also be bloody or bleeding. The cause of fire and nosebleeds is the same, both are the result of the reversal of qi and blood. From the perspective of Chinese medicine, the causes of nosebleeds can be divided into two categories: dryness, heat and weakness.

If you have frequent nosebleeds, nasal allergies, yellow or green nasal discharge, or red lips and bad breath, you are very hot. First of all, of course, it is necessary to clear away the heat, and more importantly, do not eat too much fragrant food on weekdays, snacks such as chocolate, cookies, French fries, etc., are also very hot and dry, so try to eat as little as possible. **Can be summarized as local and systemic causes.

Why do I get frequent nosebleeds? You will thank me for knowing these physical symptoms.

Hello: Nosebleeds are a common emergency in otolaryngology, most of them are sudden bleeding without warning, and some even sleep at night, and many patients are usually healthy. There are many causes of nosebleeds, which are mainly divided into two categories: local and systemic.

Most of them are caused by local causes of the nasal cavity, and the most common is the rupture of nasal blood vessels, which is mostly caused by dry weather or physical fatigue. Others include nasal mucosal dryness, erosion, nasal hemangiomas, and even malignant tumors. Systemic causes are relatively rare, such as hypertension or blood disorders such as hemophilia and thrombocytopenia.

If nosebleeds occur, it is necessary to go to the otolaryngology department of the hospital in time to identify the bleeding location and specificity, and perform professional **, such as nasal packing, electrocoagulation to stop bleeding, or intervention, vascular embolization**, etc.
