Hello,
Thanks for using Healthcaremagic!
I have gone through your query and I can understand your concerns.
As per your description,your father is having a medical condition called epistaxis(nasal bleed).
It need to be evaluated thoroughly to find out the exact cause of the condition.
I suggest you to consult an ENT consultation and get the following done:
1.Check his blood pressure,hyper tension is the common cause of nasal bleed especially in elderly.
2.Get anterior rhinoscopy(visual inspection of nose) done to look for any minor trauma or polyp which may cause nasal bleed.
3.Do Coagulation profile to rule out bleeding disorders.
If symptoms persists,other investigations like
CT scan may be needed as advised by your doctor.
As of now drink plenty of water,avoid blowing of nose and nose pricking
Hope I have answered your query.
Wishing you good health.
Regards.
Dr SHINAS HUSSAIN
