What are the causes of dizziness & nose bleeds?

Nosebleeds are common, but when a nosebleed is accompanied by dizziness that may be a signal of a more serious medical condition. Dizziness most often arises with nosebleeds because of a lack of oxygen to the brain caused by blood loss. However, it can be an accompanying symptom of illness or trauma.


Both tumours of the brain and nose can result in nasal bleeding and dizziness.

Brain Trauma

Nosebleeds and dizziness that occur after trauma to the head may indicate a fracture to the skull; you should see a medical professional immediately.

High Blood Pressure

Hypertension rarely has symptoms until it is life-threatening. At this advanced stage, dizziness and nosebleeds can occur and usually arises when hardening of the arteries is present.


Diseases such as tuberculosis, whooping cough, scarlet fever, and rheumatic fever may also cause nose bleeding with accompanying dizziness.


Often nosebleeds occur because of blood thinning medications like Warfarin, heparin and aspirin. Because the blood is unable to clot properly, excessive bleeding may occur with resulting dizziness.
