[/INST] hello,    Have low salt diet and monitor blood pressure regularly thrice a day for one week then once or twice a week. If bp is persistently more than 140/90 mmhg, then you should be on medicines for it. You should be started on Tab Amlodipine 5 mg once a day.  You should have Regular exercises like brisk walking, jogging according your capacity atleast 30 min a day and 5 days a week. Lots of green leafy vegetables, fruits, fish once or twice a week, avoid meat. Get your lipid profile and sugars tested once..  Hope this helps you and get back if you have any doubts. </s>
