== Cause == [[File:Boxing children - bloody nose.jpg|thumb|right|350px|Two children boxing, the one on the right having a nosebleed due to a punch to the face, in Vecsés, Hungary]] Nosebleeds can occur due to a variety of reasons. Some of the most common causes include trauma from nose picking, blunt trauma (such as a motor vehicle accident), or insertion of a foreign object (more likely in children).<ref name=Kell2014 /> Low relative humidity (such as in centrally heated buildings), respiratory tract infections, chronic sinusitis, rhinitis or environmental irritants can cause inflammation and thinning of the tissue in the nose, leading to a greater likelihood of bleeding from the nose.<ref name=Kell2014/>
Most causes of nose bleeding are self-limiting and do not require medical attention. However, if nosebleeds are recurrent or do not respond to home therapies, an underlying cause may need to be investigated.

Rupture may be spontaneous or initiated by trauma.

Spontaneous epistaxis is more common in the elderly as the nasal mucosa (lining) becomes dry and thin and blood pressure tends to be higher. The elderly are also more prone to prolonged nosebleeds as their blood vessels are less able to constrict and control the bleeding.
The vast majority of nosebleeds occur in the front anterior (front) part of the nose from the nasal septum. This area is richly endowed with blood vessels (Kiesselbach's plexus). This region is also known as Little's area. Bleeding farther back in the nose is known as a posterior bleed and is usually due to bleeding from Woodruff's plexus, a venous plexus situated in the posterior part of inferior meatus.<ref> The Journal of Laryngology & Otology (2008), 122: 1074–1077</ref> Posterior bleeds are often prolonged and difficult to control. They can be associated with bleeding from both nostrils and with a greater flow of blood into the mouth.<ref name="AAFP" />
{{Anchor|Pseudoepistaxis}} Sometimes blood flowing from other sources of bleeding passes through the nasal cavity and exits the nostrils. It is thus blood coming from the nose but is not a true nosebleed, that is, not truly originating from the nasal cavity. Such bleeding is called "pseudoepistaxis" (''pseudo'' + ''epistaxis''). Examples include blood coughed up through the airway and ending up in the nasal cavity, then dripping out.
==Prevention== {{Expand section|date=February 2023}} People with uncomplicated nosebleeds can use conservative methods to prevent future nosebleeds such as sleeping in a humidified environment or applying petroleum jelly to the nasal nares.<ref name="Kell2014" />
Individuals who suffer from nosebleeds regularly, especially children, are encouraged to use over-the-counter nasal saline sprays and avoid vigorous nose-blowing as preventative measures.<ref>{{Cite web |date=25 July 2023 |title=Taking control of nosebleeds - Mayo Clinic Health System |url=https://www.mayoclinichealthsystem.org/hometown-health/speaking-of-health/taking-control-of-nosebleeds |access-date=29 April 2024}}</ref>
== Treatment == Most anterior nosebleeds can be stopped by applying direct pressure, which helps by promoting blood clots.<ref name=Kell2014 /> Those who have a nosebleed should apply pressure to the soft anterior part of the nose (by pinching the nasal ala; not the bony nasal bridge) for at least five minutes and up to 30 minutes.<ref name=Kell2014 /> Pressure should be firm and tilting the head forward helps decrease the chance of nausea and airway obstruction due to blood dripping into the airway.<ref name="AAFP" /> When attempting to stop a nosebleed at home, the head should not be tilted back.<ref name=AFP2005 /> Swallowing excess blood can irritate the stomach and cause vomiting. Vasoconstrictive medications such as oxymetazoline (Afrin) or phenylephrine are widely available over the counter for treatment of allergic rhinitis and may also be used to control benign cases of epistaxis.<ref name="pmid2676467">{{cite journal|vauthors=Guarisco JL, Graham HD|year=1989|title=Epistaxis in children: causes, diagnosis, and treatment|journal=Ear Nose Throat J|volume=68|issue=7|pages=522, 528–30, 532 passim|pmid=2676467}}</ref> For example, a few sprays of oxymetazoline may be applied into the bleeding side(s) of the nose followed by application of direct pressure. Those with nosebleeds that last longer than 30 minutes (despite use of direct pressure and vasoconstrictive medications such as oxymetazoline) should seek medical attention.<ref name=Kell2014 /> Patients with frequent nosebleeds should also consider seeking medical attention to rule out other more serious causes (eg, nasal mass or tumor).

=== Chemical cauterization === This method involves applying a chemical such as silver nitrate to the nasal mucosa, which burns and seals off the bleeding.<ref name=":1" /> Eventually the nasal tissue to which the chemical is applied will undergo necrosis.<ref name=":1" /> This form of treatment is best for mild bleeds, especially in children, that are clearly visible.<ref name=":1" /> A topical anesthetic (such as lidocaine) is usually applied prior to cauterization.

Dissolvable nasal packing materials stop bleeding through use of thrombotic agents that promote blood clots, such as surgicel and gelfoam.<ref name="Kell2014" /> The thrombogenic foams and gels do not require removal and dissolve after a few days. Typically, dissolvable nasal packing is first attempted; if the bleeding persists, non-dissolvable nasal packing is the next option. thumb|Rhino Rocket: PVA Expandacell foam that swells with fluid; the applicator aids in placement. Traditionally, nasal packing was accomplished by packing gauze into the nose, thereby placing pressure on the vessels in the nose and stopping the bleeding. Traditional gauze packing has been replaced with other non-dissolvable nasal packing products such as Merocel and the Rapid Rhino.<ref name=":2" /> The Merocel nasal tampon is similar to gauze packing except it is a synthetic foam polymer (made of polyvinyl alcohol and expands in the nose after application of water) that provides a less hospitable medium for bacteria.<ref name="Kell2014" /> The Rapid Rhino stops nosebleeds using a balloon catheter, made of carboxymethylcellulose, which has a cuff that is inflated by air to stop bleeding through extra pressure in the nasal cavity.<ref name=":2" /> Systematic review articles have demonstrated that the efficacy in stopping nosebleeds is similar between the Rapid Rhino and Merocel packs; however, the Rapid Rhino has been shown to have greater ease of insertion and reduced discomfort.<ref name=":2" /> Posterior nasal packing can be achieved by using a Foley catheter, blowing up the balloon when it is in the back of the throat, and applying anterior traction so that the inflated balloon occludes the choanae.<ref name="Kill2014" /> Patients who receive non-dissolvable nasal packing need to return to a medical professional in 24–72 hours in order to have packing removed.<ref name="Kell2014" /><ref name="Stat2019" /> Complications of non-dissolvable nasal packing include abscesses, septal hematomas, sinusitis, and pressure necrosis.<ref name="AFP2005" /> In rare cases toxic shock syndrome can occur with prolonged nasal packing. As a result, any patient who has non-dissolvable nasal packing should be given prophylactic antibiotic medication to be taken as long as the nasal packing remains in the nose.<ref name="AFP2005" />
===Surgery=== Ongoing bleeding despite good nasal packing is a surgical emergency and can be treated by endoscopic evaluation of the nasal cavity under general anesthesia to identify an elusive bleeding point or to directly ligate (tie off) the blood vessels supplying the nose. These blood vessels include the sphenopalatine, anterior and posterior ethmoidal arteries. More rarely the maxillary or a branch of the external carotid artery can be ligated. The bleeding can also be stopped by intra-arterial embolization using a catheter placed in the groin and threaded up the aorta to the bleeding vessel by an interventional radiologist.<ref name="NIH" /> There is no difference in outcomes between embolization and ligation as treatment options, but embolization is considerably more expensive.<ref>{{cite journal|last=Villwock|first=JA|author2=Jones, K |title=Recent trends in epistaxis management in the United States: 2008–2010.|journal=JAMA Otolaryngology–Head & Neck Surgery|date=Dec 2013|volume=139|issue=12|pages=1279–84|pmid=24136624|doi=10.1001/jamaoto.2013.5220|doi-access=}}</ref> Continued bleeding may be an indication of more serious underlying conditions.<ref name="NIH">[https://medlineplus.gov/ency/article/003106.htm MedlinePlus Medical Encyclopedia: Nosebleed] U.S. National Library of Medicine Medline Plus service.
