Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Yes, he should visit the doctor and should get medicines prescribed. Currently, his blood pressure (BP) is on the borderline, but he will eventually need medicines.
He should have a healthy lifestyle like avoiding fatty, oily and high calorie diet. Have low salt diet and monitor BP regularly thrice a day for one week then once or twice a week.
If BP is persistently more than 140/90 mm Hg, then he should be on medicines for it. He should go for regular exercises like brisk walking, jogging according one's capacity atleast 30 min a day and 5 days a week.
He should avoid meat but must have lots of green leafy vegetables, fruits, fish once or twice a week. Avoid
smoking and alcohol if any.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Sagar Makode
