Hello and thank you for using HCM.I carefully read your question and I understand your concern.
I must tell you that
hypertension is a chronic disease.This means that it should be treated always.
In our daily practice, when we won't to treat hypertension we begin whith lifestyle modifications.A person whith hypertension should avoid salt,alcohol, caffeine products becouse they all rise blood pressure.It is advisable a low fat diet and a little exercise training,just walking for 30-40 minutes.
This for the begining than we pass to medical treatment.If you have now normal blood pressure values it is becouse of your treatment.this does not mean that you should stop the medication becouse if you do sow, pressure values will rise again and might become problematic.
So,it is a very good think that you have stabilized values now,you should continue this way.
My opinion as cardiologyst is that you should continue your treatment always and make occasionally chek ups to monitor the dosage of your medication during time. The drugs are essential to mantain you in a stable situation becouse lifestyle modifications are not always effective becouse of the complex reasons of hypertension.
Hope I was helpful.Wish you good health.Best regards.
