Why can there be blood from one nostril
Nasal bleeding was included in the proverb. When they demand something to be done, they are strictly warned: "Though the blood is from the nose!" But we are talking about those situations when the blood seems to suddenly begin to flow from the nostril itself. If this happens rarely, and blood loss is trivial, it's okay. If, however, often, one should be concerned, because many pathologies manifest themselves. Of all the causes of nasal bleeding, doctors allocate general and local.
Local causes
Injuries of internal structures of the nose, includingmucous membrane, lead to damage to the blood vessels. This often happens when foreign bodies are hit. And even because of the banal "picking in the nose" finger, what are particularly different children. Long stay under the scorching sun, visiting the steam room, too, may well lead to such an outcome. With a strong physical strain on the capillaries of the nasal apparatus also significantly increases the load. Blood can go from the nose, even from a sharp drop in atmospheric pressure. And, as a rule, from one nostril. It begins suddenly and quickly stops, without threatening health. Nasal bleeding is due to various inflammations of the nasal cavity. Such consequences are caused by a strongly curved nasal septum and mucosal dystrophy. Today, neoplasms are more often detected in the nasal apparatus. These are various angiomas, polyps, granulomas, papillomas. Rarely, but there are also malignant tumors (sarcomas). The result of the destructive effect of such pathological processes is the fragility and bleeding of the vessels.Common causes
Most often, the blood from the nose is due to increasedblood pressure in people with heart defects, hypertension, arteriosclerosis of blood vessels, kidney disease, diabetes. Such people have harbingers of bleeding: tinnitus, headache, dizziness. In colds, acute respiratory infections, influenza, which are accompanied by rhinitis, sinusitis, the capillaries of the nose are full of blood and may not withstand such pressure. In addition, they are also damaged by toxins that produce viruses. Patients suffering from hemorrhagic diathesis, poor blood coagulability, are also prone to nosebleeds. They can appear in acute infectious diseases, when a very high temperature lasts for a long time. Blood from the nose is a common phenomenon for many airmen, divers, climbers. At them this pathological syndrome arises because of sharp differences of barometric pressure which repeatedly exceeds normal pressure. The raised bleeding of nasal capillaries can be and a symptom of diseases of a spleen or a liver. Fragility, high permeability are characteristic for the walls of the vessels even with avitaminosis. It is important to distinguish the "front" nosebleed from the "back". In the anterior part of the nose apparatus is the Kisselbach zone, abundantly interwoven with a network of capillaries. She is the "supplier" of blood in 90-95% of cases. The "front" bleeding is short-term, anemic, it is easy to stop. "The rear" is extremely dangerous. It occurs when large vessels are damaged in the deep sections of the nose apparatus. Loss of blood can be significant, and in everyday life, people who are far from medicine, stop its flow usually fails.
