Hello, The blood pressure you quote is surely considered on the higher side and it might be the result of his tiredness, I would suggest you to take blood pressure at different part of time in the day on different days and see if it's persistently high, restrict salt on his diet, push him to exercise. If the readings are high do visit your doctor. Also the recent bypass to his father and aunt, would have made him sceptical about his own health, talk it out with him, just because the family members had it doesn't mean he is gonna have it. However he should take care of his diet, lifestyle to prevent any cardiac problem, due to his strong family history
