What causes nose bleeding?

Why bleeding nose
Random nasal hemorrhage is common. It may seem scary, but rarely leads to serious problems. The nose has many blood vessels that are located near the front and back of the nose. These vessels are very sensitive and therefore easily bleed. Nosebleeds are common in adults and children between the ages of 3 and 10 years.

There are two types of nosebleeds:

Anterior bleeding
This type of bleeding occurs when the blood vessels in the front of the nose are broken and bleed.

Posterior bleeding
This type of bleeding is seen in the back or deepest nose. In this case, the blood flows to the back of the throat. This type of bleeding can be dangerous.

Reasons for bleeding nose
There are several reasons for nose bleeding. Bleeding is sudden and rarely, usually not serious. If you have a constant nasal hemorrhage, you may have a more serious problem.

Dry air is one of the most common causes of nose bleeding. Living in dry weather and using a central heating system can dry the nasal membrane, which is the same tissue in the nose. This condition causes the inside of the nose to crumble, which can cause itching or burning sensation. If the nose is scratched or the skin is removed, bleeding occurs.

The use of antihistamines and constipation drugs for allergies, colds or sinus problems can also result in drying of nasal mucous membranes and nasal bleeding. Finishing is consistently another cause of nose bleeding.

 

Other common causes of nosebleeds include:

Presence of foreign body in the nose
Chemical stimulants
Allergic reactions
Nose damage
Frequent sneezing
Cold Weather
Upper respiratory tract infection
Taking a high dose of aspirin
Hands on nose
Other causes of bleeding in the nose:

High blood pressure
Bleeding problems
Disruption of blood clotting
Cancer
Most nasal bleeding does not require medical attention. However, if your bleeding lasts longer than 20 minutes, or if this happens after an injury, you should seek medical attention. It may be a sign of posterior nosebleed that is dangerous. Damage that can lead to bleeding in the nose, including falling, driving accidents or punching. Hence, nose bleeding that occurs after injury can indicate nasal failure, skull fracture, or internal bleeding.

Diagnosis of nose bleeding
If you are seeking medical care for your bleeding, your physician may find the cause for physical examination. The doctor examines your biathlon to find a sign from a foreign body. You also ask questions about your medical history and the drugs you have just taken.

Inform your doctor about any other symptoms or injuries you have recently suffered. There is no specific and specific test to determine the cause of nose bleeding. However, your doctor may use a variety of diagnostic tests to determine the cause of bleeding. These tests include:

Complete Blood Cell Count (CBC): This is a blood test to check for blood disorders.
Relative Thromboplastin Time (PTT): This is a blood test that examines the time it takes to make blood clots.
Nose endoscopy
CT scan nose
Face and Nose Examination Using X-rays
How to treat nosebleeds?
Treatment for nosebleeds is highly dependent on the cause and the type that we will talk about later:

Anterior hemorrhage of the nose
If you have anterior hemorrhage, the front of the nose, and usually the nasal passage of the nose, it's bleeding. You can also treat this type of bleeding at home. While sitting, press the soft squeeze section. Make sure the nostril is completely closed. Hold the nasal hole for 10 minutes, bend slowly forward and breathe through your mouth.

 

Do not lie down when trying to strain your nose bleeding. Sleeping causes blood to swallow and cause stomach upset. After 10 minutes, release the nose and check if bleeding has stopped. If the bleeding continues, repeat these steps. You can also use cold compresses in the upper nasal passages or nasal congestion sprays to close small veins in the nose.

If you can not catch a nosebleed, be sure to refer to your doctor immediately. You may have posterior nose bleeding that requires more serious treatments.

Posterior nasal hemorrhage
If you have a posterior bleeding, the back of the nose is bleeding. In this case, the blood can pour into the throat. This type of bleeding is less common than anterior bleeding, but it is often more dangerous than it is. This type of nosebleed should not be treated at home. If you think you have posterior bleeding, see a doctor or emergency department immediately.

How to prevent nosebleeds?
Use air humidifiers at home.
Do not hold your hands.
Limit the use of aspirin, as it can lead to thinning of the blood vessels and nosebleeds. Talk to your doctor first, because the benefits of aspirin may be greater than its risks.
Use antihistamines and anti-congestion at the equilibrium level, these drugs can dry the nose.
Use a spray or salt gel to keep the nasal airways wet.
