The cause of nosebleeds can generally be divided into two categories, ''[[local]]'' and ''[[:wikt:systemic|systemic]]'' factors.
===Causes in Alphabetical Order===
=== Local factors ===
*[[Abnormal nasal anatomy]]
* Anatomical deformities, such as septal spurs or [[Hereditary hemorrhagic telangiectasia|Osler-Weber-Rendu Syndrome]]
*[[Acute respiratory tract infections]]
* [[Inhalant|Chemical inhalant]]
*[[Acute sinusitis]]
* Inflammatory reaction (eg. acute respiratory tract infections, chronic sinusitis, allergic rhinitis and environmental irritants)
*[[Aging]]
* [[Foreign body|Foreign bodies]]
*[[Alcohol (due to vasodilation)]]
* Intranasal tumors ([[Nasopharyngeal carcinoma]] in adult, and [[nasopharyngeal angiofibroma]] in adolescent males)
*[[Allergic rhinitis]]
* Nasal prong O<sub>2</sub> which tends to dry the nasal mucosa
*[[Allergies]]
* Nasal sprays, particularly prolonged or improper use of nasal steroids
*[[Anticoagulant use ]]
* Surgery (such as septoplasty and endoscopic sinus surgery)
*[[Antiplatelet medication]]
* [[Physical trauma|Trauma]] (usually a sharp blow to the face)
*[[Antrostomy]]
* [[Nose-picking]]
*[[Aplastic anemia]]
* Low relative humidity of air breathed occurring especially during winter seasons.
*[[Aspirin]]
===Systemic factors===
*[[Atherosclerosis]]
* Drugs - [[Aspirin]], [[Fexofenadine]]/[[Allegra]]/[[Telfast]], [[warfarin]], [[ibuprofen]], [[clopidogrel]], [[isotretinoin]], desmopressin and others
*[[Barotrauma]]
* [[Alcohol intoxication|Alcohol]] (due to [[vasodilation]])
*[[Blood dyscrasias]]
* [[Allergies]]
*[[Broken nose]]
* [[Dyscrasia|Blood dyscrasias]]
*[[Chemical irritants]]
* [[Heart failure]] (due to an increase in [[blood pressure#Venous pressure|venous pressure]])
*[[Christmas disease]]
* [[Hematological malignancy]]
*[[Chronic sinusitis]]
* [[Hypertension]]
*[[Clopidogrel]]
* [[Infectious diseases]]
*[[Coagulopathies]]
* [[Malnutrition]] (especially [[anemia]])
*[[Cocaine]]
* [[Narcotics]]
*[[Cold dry air]]
* Vascular disorders
*[[Common cold]]
* [[Nose-picking]] (especially in children)
*[[Cystic fibrosis]]
* Muscle tightness as caused by [[scoliosis]] (the tightened muscles cause blood vessels to become constricted, resulting in nosebleeds from the same side as the tightened muscles).
*[[Dental extraction]]
*[[Desmopressin]]
*[[Deviated septum]]
*[[Dry nasal mucosa]]
*[[Endoscopic sinus procedures]]
*[[Excessive dieting]]
*[[Facial surgery]]
*[[Fexofenadine]]
*[[Foreign body in nose]]
*[[Gastroesophageal reflux ]]
*[[Heamophilia]]
*[[Heart failure (due to an increase in venous pressure)]]
*[[Hematological malignancy]]
*[[Hepatitis]]
*[[Hereditary haemorrhagic telangiectasis]]
*[[Hypertension]]
*[[Iatrogenic]]
*[[Ibuprofen]]
*[[Infectious diseases]]
*[[Inhaled steroids]]
*[[Intranasal rhabdomyosarcoma]]
*[[Intranasal tumors (Nasopharyngeal carcinoma in adult, and nasopharyngeal angiofibroma in adolescent males)]]
*[[Isotretinoin]]
*[[Juvenile nasal angiofibroma ]]
*[[Leukemia]]
*[[Malnutrition (especially anemia)]]
*[[Migraine]]
*[[Narcotics]]
*[[Nasal congestion]]
*[[Nasal excoriation]]
*[[Nasal infection]]
*[[Nasal polyp]]
*[[Nasal prong O2 which tends to dry the nasal mucosa]]
*[[Nasal septum deviations]]
*[[Nasal trauma]]
*[[Nasal tumors]]
*[[Nassal ulceration]]
*[[Nose conditions]]
*[[Nose picking]]
