Causes of nosebleeds: Overwork
At the Sneezing, but also when blowing your nose vigorously your fine blood vessels in your nose are under high pressure. The result: they tear more easily. Therefore, from time to time, sudden nosebleeds occur. However, the cracks in the vessels also close quickly with normal coagulation, so that with such a Nosebleed emergency measures take effect quickly.
You can also mechanically overload or injure your veins in your nose, for example through this picking in the nose. have the same effect foreign bodythat get into the nose. Children in particular are keen to experiment and stick little things like peas, beans or even Lego bricks up their noses. These can then become the cause of nosebleeds in the little ones. If the foreign body is removed and the nasal mucosa can heal, the bleeding will stop fairly quickly.
Environmental causes of nosebleeds
Especially when the mucous membranes do not have optimal conditions, the blood vessels that run through them are also more sensitive. Dry heating air, dust or chemicals in the air irritate and dry out the nasal mucosa. It becomes thinner and more sensitive. This makes sudden nosebleeds more likely.
The longer your nose is exposed to unfavorable conditions, the greater the damage to the mucous membrane – and the greater the likelihood that exposure will cause nosebleeds.
Optimizing the air quality in the room helps to prevent this harmless bleeding. If you are exposed to polluted air at work, a mask, for example, can help.
Causes of nosebleeds: diseases as triggers
at Colds, flu or other infectious diseases blowing your nose when you have a cold is not the only cause of nosebleeds. To fight the infection, more blood also flows through the mucous membranes of the nose. The vessel walls are then under greater tension and can tear more easily.
The same can happen if you are under Allergies suffer. Here, nosebleeds can occur more frequently if you come into contact with allergens, which then trigger inflammation in the nasal area. This makes hay fever, for example, even more uncomfortable for some allergy sufferers.
But also diseases of the vascular system such as too high blood pressure or atherosclerosis can cause nosebleeds. Other organic causes can as well diseases of the kidney be.
If you have one Coagulation disorder such as hemophilia is known, this might also cause the sudden nosebleed.
Since the nosebleed occurs as a symptom here, the treatment of the underlying disease is particularly important. Then the bleeding will disappear or at least become less frequent.
Drugs as a cause of nosebleeds
Sometimes, however, the cause of your nosebleeds is not diseases, but medications that you are taking. The hit list lead the so-called blood thinner on. They ensure a dynamic that is similar to that of coagulation disorders: Small tears in the vessels do not close once more immediately and the blood then visibly runs out of the nose.
A typical representative of these blood-thinning drugs — which you may not think of — is this Acetylsalicylic acid (short: ASA). Actually, it is a typical pain and fever medication. However, it also prevents the platelets from accumulating on one another and thus being able to close open wounds. This makes it easier for your nose or gums to bleed.
Another cause of nosebleeds are so-called Cumarinethat are contained in some medicines. These substances lower the level of vitamin K in the blood, which is essential for blood clotting. If the level in the blood drops, coagulation is inhibited so that even small injuries bleed longer. Therefore, sudden nosebleeds become more likely when taking coumarins.
Sudden nosebleeds following injuries
Do you get one slap on the nose, you fall or have another accident, the cause of the nosebleed should be clarified by a doctor. The nasal septum or nasal bone itself does not always have to be injured. Even if your nose is fine, you should always see a doctor if you have a nosebleed to rule out serious causes. There may also be other injuries to the skull that cause bleeding that drains through the nose. Since you cannot see injuries in the skull from the outside, imaging procedures are necessary for clarification.
