Examples include anticoagulants like Coumadin or Jantoven (warfarin), the anti-platelet medication Plavix (clopidogrel bisulfate), over-the-counter drugs like aspirin, and prescription or over-the-counter NSAIDS like naproxen. Blood-Thinning Medicationsīecause blood clotting is a necessary step in preventing or stopping a nosebleed, any medication that changes the blood’s ability to clot can cause a bloody nose - or make one harder to stop. Examples of these items include small toys, pebbles, food, erasers, and dirt. This is most common among small children, who explore their world by putting objects in their mouth, nose, or ears. Nosebleeds can also occur if a foreign object is placed in the nose. Using a humidifier while sleeping can help relieve dryness, and nasal sprays are helpful for moistening the nostrils. Dry Airĭry air from indoor heating or outdoor cold can dry out the lining of the nose, causing it to crack and bleed. Heart conditions like hypertension (high blood pressure) and congestive heart failure can also cause nosebleeds, as can hypertensive crisis - a sudden, rapid increase in blood pressure that may be accompanied by a severe headache, shortness of breath, and anxiety, according to the American Heart Association (AHA).Ĭolds, allergies, and frequent nose-blowing can also irritate the lining of your nose, resulting in a nosebleed. Liver disease, kidney disease, chronic alcohol consumption, or another underlying health condition can lower your blood’s ability to clot and therefore cause your nose to bleed. To put you at ease in case you have one, we've assembled a list of common culprits, as well as tips on how to treat a bleeding nose and when to seek medical care. Sudden and inexplicable nosebleeds may seem scary, but typically they're not. An injury to the nose and high blood pressure are the most common causes of posterior nosebleeds. Posterior nosebleeds can be dangerous for example if blood leaks into your throat. These begin deeper in the nose when the nasal cavity is damaged and bleeds. Posterior nosebleeds, on the other hand, are much less common. It contains many blood vessels that can break from a simple scratch or a blow to the face. The most common origin site of an anterior nosebleed is the septum, or the part of the nose that separates your nostrils. These types of nosebleeds can usually be treated at home. There are two types of nosebleeds: those that originate in the front of your nose, called anterior nosebleeds, and those that start in the back of it, or posterior nosebleeds.Īnterior nosebleeds are very common and typically not that dangerous. Any of these conditions can cause the surface blood vessels in the nose to bleed. 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. Nosebleeds are common, and while the cause may be unclear at first, most cases are minor and can be managed from home.
