Hello, thanks for the query to H.C.M.
You are taking medicines for high B P ( hypertension).
Dizziness frequently that too when you are on anti hypertensive medicines , very bad.
In my opinion your's lower blood pressure is too high which you haven'e described in query.
See an example 150/100 ( >90) , here cause of concern is 90 or 100 because this is very dangerous for health.
I would like to say that this diastolic ( lower B P ) blood pressure is very high (>100 or so) for some time , I usually term it as a silent killer.
Dizziness in your's case is related to
essential hypertension ( lower B P with secondary cause) and so without any delay please consult a doctor and take advice accordingly.
Also get in blood examination for
lipid profile and sugar.
Mieneir's disease is another reason for dizziness and
hearing loss but it seems it is not in your case.
Regards. Dr. HET
