Hi.
Thanks for your query.
Read and understood your history about your friend who has
nosebleeds for 1 year with spells of
dizziness and
nausea.
The reasons can be benign or malignant.
The benign are, ulcer, hypertensive arterial spurts, scabbing or some bleeding disorders.
The malignant means there can be a
tumor that causes the bleeding.
To decide the reason it is important that the friend be having clinical evaluation, examination ENT
endoscopy and MRI of the nose and brain.
This will help to get the correct diagnosis and the plan for the proper treatment as per the cause found.
If he is hypertensive, blood pressure should be kept under control, if there is a bleeding point to cauterize the points.
If cancer or so, this will need the operation for removal.
