(Concern)(Story) I'm in my early 40s and have high blood pressure.

Hello, I turned 40 and for the first time in my life I had a comprehensive health checkup. Haha. I have had varicose veins for a while, and when I checked my blood pressure, it was around 135, so I was barely able to undergo an endoscopy. I heard that if your blood pressure is high, you can't have an endoscopy. When I got home and measured my blood pressure with a monitor, sometimes it was 150 in the morning on an empty stomach. The doctor said I don't need medication yet and that aerobic exercise would help, so I walk 10,000 steps every day, but my blood pressure still seems to be around 140-150. Is there a better way to manage this? I also tried taking Coenzyme Q10 but stopped; should I keep taking it?
