Nosebleed: what it is and symptoms
Medically it is known as epistaxis, and this is nothing more than the hemorrhagic process that comes from the nostrils. Colloquially, any nosebleed can occur repeatedly and affect both women and men.
Nasal bleeding is a common complaint in which the medical emergency area is not usually serious, but to be a sufferer turns out to be worrying. Generally, nasal bleeding can be scarce AND self-limited, although in some cases, it occurs repeatedly. It usually occurs through a single nostril. However, it can also be bilateral (in both nostrils) as blood flows through the back of the nostrils.
In other cases, epistaxis can be expelled through the mouth if the blood is directed towards the nasopharynx area. likewise, bleeding from the nose can be accompanied by:
- Threw up.
The Epistaxis Diagnosis and Treatment Clinical Practice Guide estimate that 60% of the population will suffer some degree of epistaxis in their lifetime. Only 6% will require medical attention for its treatment and control. The rest have no underlying systemic cause. 
Why is blood coming out of the nose all of a sudden
Here are some of the leading causes of sudden nosebleeds :
- In the first place, it must be considered that sudden nosebleeds can appear due to physical injuries. This occurs when any innumerable blood vessels there suffer some trauma from an accidental blow or even clean with intensity.
- Second are the common colds and allergic rhinitis, which repeatedly touches the nose, sometimes with great force and intensity, causing the nosebleed.
- Another reason that can suddenly trigger nosebleeds is the dry environment; this, in turn, causes the person to repeatedly unconsciously touch the nose, bringing the injury to any blood vessel that triggers epistaxis or nasal bleeding.
- The presence of a benign tumor in any area related to the nasal passages can generate an increase in pressure on the blood vessels that are responsible for bringing blood to the nose, causing, in turn, the rupture of some of them and consequently epistaxis in this case Nosebleeds can occur repeatedly and will intensify as the tumor grows.
- When there is an increase in blood pressure, the body likely externalizes it through the nosebleed. In this case, the bleeding may be minimal but can occur repeatedly.
Other causes of nosebleeds
On the other hand, other causes can also be related to bleeding from the nose. It is indisputably worth going to the doctor to rule out any severe reason to treat:
- Rhinosinusitis and tuberculosis both trigger an infectious nasal inflammatory process that may result in the presence of epistaxis or nosebleed.
- There may also be abnormalities or deviations in the nasal septum and intranasal foreign bodies related to the presence of sudden bleeding from the nose.
- Diseases related to the hematological system can manifest with hemorrhage through any hole. One of them is the nostril, which includes congenital coagulopathies such as hemophilia. The use of antiplatelet drugs and anticoagulants also triggers nasal bleeding.
- The pregnancy can increase the vascularity of the mucous membrane lining the nose internally while generating possible nosebleeds.
Finally, other associated reasons are the presence of:
- Malignant tumors.
- Liver diseases
The diagnosis of bleeding from the nose is purely medical and will depend on its severity. It requires quick and effective control. The main objective will be to identify the location of the bleeding; this is achieved by performing an anterior rhinoscopy and other paraclinical tests such as nasal endoscopy and exploration of the oropharynx.
