What are the signs of nosebleed

The nose is a very sensitive organ. It will cause nosebleeds if you are not careful. We often do not take nosebleeds seriously because most nosebleeds will stop on their own. In fact, a normal nasal cavity is composed of many tiny capillaries and will not cause nosebleeds. Once a nosebleed occurs, it means that the capillaries in the nasal cavity have burst. So what causes it? What are the signs of nosebleeds? In which situations of nosebleeds should we pay attention?

1. Dry weather

Nosebleeds in dry weather may be caused by dryness of the lungs and heat in the blood due to the dry weather. People with dry lungs and hot blood are prone to dry nasal cavities, which increase the fragility of capillaries in the nasal cavity and make it easy for capillaries to burst and cause nosebleeds. In addition, if the weather is dry, the body will adjust itself and allow more blood to flow through the nasal cavity to maintain the normal physiological function of the nasal cavity. The capillaries of the nasal mucosa are prone to congestion and nosebleeds. In addition, people who like to eat hot foods are also prone to nosebleeds.

2. Habit of picking your nose

People who are used to picking their noses hard are prone to nosebleeds due to external force damaging the blood vessels in the nasal mucosa. In addition to nosebleeds caused by frequent nose picking, nosebleeds may also occur if you are used to blowing your nose hard or when your nose is hit by other external forces.

3. Nose diseases

If you have sinusitis or other nasal diseases, nosebleeds are likely to occur. Inflammatory infection or fungal bacterial infection may cause rupture of blood vessels in the nasal mucosa. Especially when there is a hemangioma in the nose, the amount of nosebleed will be heavier.

4. Systemic diseases

In addition to local symptoms in the nose, systemic blood diseases or acute febrile infectious diseases can also cause damage to blood vessels. The nasal mucosa is in a state of severe congestion and dryness, and capillaries can easily rupture and cause nosebleeds.

5. Vitamin deficiency

If the body lacks vitamins C, K, P, or lacks minerals and calcium, it will cause nosebleeds. Especially for young children and adolescents whose bodies are in a period of rapid growth and development, they must pay attention to supplementing the nutrients needed by the body.

6. Estrogen effects

For women who are menstruating or pregnant, nosebleeds are very common due to the large amount of estrogen produced in the body. Large amounts of estrogen can cause the blood vessels in the nasal mucosa to swell, become congested and thickened, and the elasticity of the blood vessel walls decreases, making them easily rupture and bleed with just the slightest stimulation. If a pregnant woman has severe nosebleed, she should seek medical attention immediately.

7. Nose injury

If you suffer a fracture due to a violent impact, or if you are cut, hit, or have other external injuries, the wound will be larger and you may also experience frequent nosebleeds.
