Lots of Fragile Blood Vessels Present
Your nasal cavity has lots of blood vessels in it. They are there in order to help warm the air that you are breathing in. Your nasal cavity is also lined with mucous membranes that help to humidify the air entering your nose. It’s important to keep the air you are breathing in warmed and humidified in order to save your lungs from ending up dry.
Unfortunately, those blood vessels found in your nasal cavity are kind of fragile, which means that they can break easily. That’s basically how a nosebleed happens, although the reason for it striking can be due to different things, depending on which has caused the blood vessels to break.
Different Nosebleed Causes
There are a lot of things that can cause your nose to bleed. According to doctors, one of the most common reasons is exposure to dry air. That’s because such can cause the mucous membranes of the nasal cavity to end up parched and crusted. When that happens, it can be very easy for the blood vessels to break and leak blood.
It’s for this reason why nosebleeds are very common among people who are living in dry parts of the planet as they are constantly breathing in air that can easily dry up the mucous membranes.
Aside from breathing in dry air, another very common reason why the mucous membranes end up dry and thus cause a nosebleed to strike is the intake of antihistamines and decongestants. These drugs are taken in order to deal with runny or stuffy nose, and in order for them to work they have to force the mucous membranes of the nasal cavity to dry up.
Speaking of stuffy or runny nose, another very common cause of a nosebleed is frequent blowing of the nose. The increase in pressure in your nasal cavity each time you blow your nose, especially if you do it aggressively, can cause the fragile blood vessels in there to break.
Frequent picking of the nose, trauma or injury to the nose, exposure to chemical irritants, and foreign objects stuck in the nose are some other common causes of nosebleeds.
Certain Medical Conditions May Cause Them, Too
Some people are simply more prone to having nosebleeds than others because of certain medical conditions. Needless to say, they will continue having nosebleeds for as long as the underlying medical cause is poorly managed or not treated.
One example of a medical condition that can cause a person to have frequent bouts of nosebleeds is hypertension or high blood pressure. Due to the increased pressure applied by the blood on the walls of the blood vessels, those delicate blood vessels situated in the nasal cavity can rupture rather easily, thus allowing blood to escape from them.
According to doctors, other medical conditions that can cause frequent nosebleed include bleeding disorders, blood clotting disorders and certain types of cancer.
