The inside of the nose is covered with moist, delicate tissue mucosa that has a rich supply of blood vessels near the surface. When this tissue is injured, even from a minor nick or scratch, these blood vessels tend to bleed, sometimes heavily. Nosebleeds near the front of the nose, called anterior nosebleeds, are very common since this is the most accessible area to injury.
Stemming a flood from your nose can be embarrassing and inconvenient. Central heating or air conditioning can cause the inside of the nose to dry out. Dry and dusty regions can have the same effect.
It is usually noticed when blood drains out through the nostrils. There are two types: anterior the most commonand posterior less common, more likely to require medical attention. Sometimes in more severe cases, the blood can come up the nasolacrimal duct and out from the eye.
Bloody noses are common and can be caused by a variety of factors including dehydration, cold, dry air, sinusitisallergiesblood-thinning medications, and trauma. For example, you'll be more likely to get a bloody nose after accidentally bumping it if you're already dehydrated or suffering from sinus problems. That said, usually, a bloody nose is nothing to worry about but there also are situations in which a bloody nose is a medical emergency and should be tended to right away.
We respect your privacy. Nosebleeds are common, and while the cause may be unclear at first, most cases are minor and can be managed from home. Immediate causes of nosebleeds include trauma to the nose from an injury, deformities inside the nose, inflammation in the nose, or, in rare cases, intranasal tumors.
Sitting in science class one afternoon, you feel your nose begin to run. As you wonder if you're catching a cold, you wipe your nose with a tissue and are shocked to see blood! You have a nosebleed, and if you're like most teens, you may be embarrassed.
Don't drive yourself to an emergency room if you're losing a lot of blood. Call or your local emergency number or have someone drive you. Talk to your doctor if you're having frequent nosebleeds, even if you can stop them fairly easily.
Doctors hear this question a lot, especially from parents. They may report that their children sometimes bump their noses or fall down and get nosebleeds. While this can be distressing, at least these parents know the cause. More concerning are nosebleeds that seem to happen without a cause.
The lining of your nose contains many tiny blood vessels that lie close to the surface and are easily damaged. In general, nosebleeds are not a symptom or result of high blood pressure. It is possible, but rare, that severe high blood pressure may worsen or prolong bleeding if you have a nosebleed. Causes shown here are commonly associated with this symptom.
