Thanks for your query.
Nose bleeding is related to Diabetes due to atherosclerosis
. Other causes may include infection, trauma,abnormal nasal bone, foreign body,blood/vessel abnormality and malignancy. Some drugs like Warfarin and Asprin can predispose to nasal bleeding
Immediate treatment of nose bleeding includes pinching the nose,direct pressure, Ice pack or nasal packing and cautery using topical medications may also be needed.
I would advise to take proper diet with vitamin C supplement
, as its deficiency may cause nose bleeding.
Visit your doctor to rule out any infection or blood disorder.
Hope it helps.
