Hi Mrs Lin I totally understand your concerns. At the same time, I wish to ally your fears a bit. It is unfortunate that he has been diagnosed with hypertension(high blood pressure) at this young age. Although having hypertension, puts him at a risk for future cardiovascular illnesses such as ischemic heart disease and cerebrovascular disease, several studies have shown that with the adequate life style changes and regular medications, these risks can be significantly reduced. The progression of the disease can be slowed to a great extent with these medication. Some of the medication for hypertension are extremely safe and do not affect the quality of life such as losartan, telmisartan, olmesartan.. His GP will guide him in this anyways.. In fact people could live much longer with hypertension than what you just mentioned. Drug therapy is essential in his situation besides salt restriction and some kinds of relaxation techniques including spiritual exercises would do him a world of good. Taking too much stress upon himself is not a good thing to do and it is good for him to take breaks. Apart from this he can lead a normal life style like anybody else and so you must not be too worried at this stage. Hope I answered your concerns.
