Hello!
Thank you for asking on HCM!
I understand your concern and would explain that it is not an abnormal finding for the blood pressure to lower.
This happens if you modify your lifestyle (a healthy diet,
weight loss, physical activity), or treat the cause of a possible
secondary hypertension.
Sometimes, especially in young persons,
high blood pressure can also be reversible.
What is your actual bp therapy?
But 135/64mm Hg, are not too low blood pressure values. You should not forget that these values are measured while you are on an antihypertensive therapy.
That is why, I would recommend to closely monitor your blood pressure and gradually decrease the dose of your bp medicine if needed.
But I would not recommend to stop taking it, because you may be at risk for any uncontrolled high blood pressure episode.
Hope to have been helpful!
Feel free to ask any other questions, whenever you need!
Greetings!
Dr. Iliri
