According to the American Family Physician’s website, 60% of people experience nosebleeds, with more men than women. The causes of nosebleeds are very diverse; blunt force, infection, mechanical irritation, allergies, dry air, colds, etc.
The most prone to epistaxis are nasal septal hemangioma, nasopharyngeal fibrovascular tumor, bleeding nasal polyp and malignant tumor of nasal cavity and sinus. A small amount of nasal bleeding or blood in the snot is one of the main symptoms of malignant tumors in the early stage.
It is common in children, mostly unilateral nasal bleeding, because the nasal foreign body stays in the nasal cavity for a long time, which can cause the nasal mucosa to erode and bleed. Animal nasal foreign bodies, such as leeches, can cause repeated massive nasal bleeding.
Such as epiglottitis, influenza, hemorrhagic fever, scarlet fever, malaria, measles and typhoid fever.Mostly due to high fever, toxic damage to blood vessels, nasal mucosa congestion, swelling and dryness, resulting in capillary rupture and bleeding. In general, the amount of bleeding is small, mostly occurs in the fever period, and the bleeding site is mostly located in the anterior part of the nasal cavity.
Pregnancy, premenopause and menopause can cause epistaxis, which may be related to increased capillary fragility. Patients with severe liver disease can have epistaxis caused by impaired synthesis of coagulation factors by the liver. Uremia can also cause epistaxis. Nosebleeds can be one of the early manifestations of rheumatic fever.
Note that nosebleeds are a relatively common disease in clinical practice, so many people feel indifferent to nosebleeds. If nosebleeds are prolonged, you need to pay attention to them and seek medical attention promptly.
Nosebleeds sometimes occur repeatedly, and more attention should be paid to prevention in general.
Correct: Because the rear of the nose is the same as the pharynx in terms of anatomical structure, tilting the head can prevent blood from flowing out of the nasal cavity on the surface, but this blood will flow into the pharynx from the rear and can be easily swallowed, causing nausea and other discomfort. In order to avoid the discomfort caused by swallowing blood, the nasal bleeding should maintain a slightly forward leaning body posture.
Correct approach: This method can actually stop the bleeding, the principle is to compress the nasal blood vessels through physical action to achieve pressure to stop bleeding, but toilet paper, cotton balls and other items do not guarantee sterility, plus the bleeding point in the nasal cavity when nasal bleeding often has damage, bacteria can easily enter the wound, leading to local infection. What is more dangerous is that the nose is within the “danger triangle” of the face, and infection in this area may lead to serious infectious cranial sinus thrombosis, and even life-threatening.
Correct: Although up to 85% of nosebleeds are idiopathic nosebleeds with no specific cause, for a significant number of patients with recurrent, severe nosebleeds, the possibility of a combination of other moderate to severe nasal diseases is still not uncommon. For example, some hematologic diseases (e.g., aplastic anemia, leukemia) and nasopharyngeal tumors may have recurrent nasal bleeding as the first manifestation. Therefore, those who bleed continuously or frequently should seek prompt medical attention.
