Does Your Blood Pressure Vary Due to Anxiety?

I am in the process of adjusting my blood pressure medicine. This has been on-going since about February of this year. I have been tracking my readings for about 7 to 8 months.

The trouble is my blood pressure varies widely over the course of the day I think due to the stress and anxiety and erratic nature of my bipolar illness. Also if I go to an appointment that is stressful like the dentist or for a mammogram, my stress level soars and my blood pressure climbs.

My dental hygienist indicated yesterday there is something called “white coat syndrome” where your blood pressure rises upon seeing someone in the medical establishment (doctor or dentist or someone in that profession) wearing a “white coat.” When I first arrived for my dental cleaning yesterday, my blood pressure levels were very high. I asked again at the end of the appointment whether my levels could be checked again — and they were normal.

Does anyone else have volatile blood pressure readings? That might be tied to anxiety levels? Or suffer from high blood pressure readings when stress is high?
