A nosebleed occurs when the lining of the nasal cavity gets irritated by one of many causes.
A nosebleed can begin suddenly or over the course of a few minutes. Common reasons that a nosebleed occurs include dry air (whether you’re in your home or outside) or picking at the inside of your nose. A sinus infection or allergies are also causes of nosebleeds.
If you have frequent nosebleeds, then it could be an indication of a sinus infection or an indication that you are allergic to something that is in your environment that you didn’t know about.
If you’re on blood thinners, then you might notice that you have frequent nosebleeds as the capillaries in the nose are often thinner than those in other areas of your body. Any time that you are breathing in chemicals, such as ammonia or bleach, then there is a possibility that your nose could start bleeding. The chemicals can begin to burn away the lining in the nose if you inhale them for a long period of time. Blowing your nose when you have a cold can often result in bleeding because you have loosened the mucus from the sinuses and the nasal cavity. High blood pressure can sometimes make nosebleeds worse, but it’s usually not a common cause for bleeding to take place.
Seeing A Doctor
There are a few circumstances when you want to see a doctor. If you notice large blood clots, then you should consult with a doctor who can determine if there are any polyps in your nose or sinuses. You should also consult with a doctor if you experience any headaches with nosebleeds or if they occur after an injury. If you have been compressing the side of the nose that’s bleeding for about 30 minutes or longer with no changes, then you should seek medical advice. Avoid driving yourself to a doctor’s office or a hospital if the bleeding is severe or if there are other issues occurring along with the bleeding.
Treating A Nosebleed
Before going to a doctor or an emergency room, there are some things that you can try on your own. Sit as straight up as you can with your head tilted forward. Some believe that you should lean your head back, but this only allows the blood to drain back into the sinuses and down your throat. Once the bleeding slows, try to blow your nose to get any clots out. A nasal decongestant can help to clean the nose as well. Pinch the side of the nose that’s bleeding shut with your index finger and your thumb. Check to see whether your nose is still bleeding after about 15 minutes. Try to keep your head higher after the bleeding stops so that it won’t start again.
