Three continuous reading of BP is required to label hypertension
. I am not sure weather three readings were taken before starting medication. Any family history of hypertension?
At the age of thirty it is unusual to have hypertension. A detailed investigation would be required to find out the cause for hypertension. For your age a reading of 140/90 is high.
