Nosebleeds PDF – Ear, Nose, and Throat Disorders. Some people have nosebleeds frequently, while others only get them once in a while. There could be a trickle or a powerful torrent of blood. People who consume blood frequently vomit it up because blood irritates the stomach. Blood that has been swallowed might transit through the digestive tract and show up in the stool as black tarry stools.
Small blood veins on the cartilage that separates the two nostrils cause nosebleeds in the front region of the nose (anterior nosebleed). The nasal septum is cartilage that contains several blood veins. The majority of anterior nosebleeds are more alarming than dangerous.
Although infrequent, bleeding from blood vessels in the back of the nose (posterior nosebleed) is more harmful and difficult to treat. Blood vessels in the posterior nosebleeds are usually larger than those in the anterior nosebleeds. Because these veins are located in the back of the nose, surgeons have a difficult time reaching them for treatment. People with atherosclerosis (which lowers or stops blood flow in arteries), bleeding disorders, blood-thinning medications, or who have had nasal or sinus surgery are more likely to get posterior nosebleeds.
Nosebleeds: What Causes Them?
When the moist inner lining of the nose is irritated or when blood vessels in the nose are ruptured, nosebleeds develop. Nosebleeds can be caused by a variety of factors. People who take aspirin or other blood-thinning drugs (anticoagulants), people with clotting abnormalities, and people with arteriosclerosis (hardening of the arteries) are all more likely to get nosebleeds.
The most common causes of nosebleeds are
Trauma (such as nose blowing and picking)
Drying of the moist inner lining of the nose (such as occurs in winter)
The following are some of the less prevalent causes of nosebleeds:
- Nasal infections
- Foreign objects
- Rendu-Osler-Weber syndrome
- Tumors of the nose or sinuses
- Bleeding disorders (coagulopathies)
- Disorders that affect the entire body (systemic disorders)
- High blood pressure (hypertension) may aid in the continuation of a nosebleed that has already started, but it is unlikely to be the cause.
Evaluation of Nosebleeds
The following information can assist people in determining whether or whether a doctor’s evaluation is required, as well as what to expect during the evaluation.
Signs to be aware of
Certain symptoms and characteristics in those who have a nosebleed should be taken seriously.
They include the following:
- Excessive blood loss symptoms (such as weakness, fainting, or dizziness when standing up)
- Interfering with blood clotting with medications
- Symptoms of a bleeding disorder or a previously diagnosed bleeding disorder (such as hemophilia)
- Several recent bouts of nosebleeds, especially those with no obvious explanation
