As my doctor approaches me with his blood pressure monitor, I tell him that I suffer with white-coat syndrome – or rather, white-coat hypertension: my anxiety levels and blood pressure rise as soon as I walk into his clinic.
Sure enough, cuff tight about my arm, my heart pounding, the machine beeping, it gives a reading higher than it should be: 140/90, diagnosed as hypertensive Stage 2.
“I promise you, it’s not normally that high!” I bleat.
My doctor is sceptical and insists on a 24-hour continuous reading. I go home strapped to a mini mobile unit to keep an eye on the numbers overnight: systolic and diastolic.
Systolic (the first number) – indicates how much pressure your blood is exerting against your artery walls when your heart beats.
