Hello, Welcome and thanks for your query. The reading is high but that doesn't confirm that your father has hypertension. He needs to have his blood pressure checked for 5 days at different times or can do a 24 hour ambulatory blood pressure monitoring in his normal working environment, if facility is available. It will confirm whether he has hypertension and what will be the best approach for him. In the meanwhile let him reduce salt and animal fats if he takes them and try to relax and walk for 30 minutes a day. Do get back to me if you have further questions.

Tell me your father's age and other conditions as well.
