My blood pressure was 123/80 before I ate a load of sugar. When I woke up, it had shot to 140/106. Did eating the sugar cause this?
It's unlikely the high sugar intake caused your elevated morning blood pressure. Sleep apnea is one possible cause high blood pressure readings in the morning. I recommend discussing with your physician.
