My blood pressure drops after eating, when exercising, and when air pressure is low.

I experience sudden drops in blood pressure without doing anything.

I do not feel refreshed after doing exercises such as yoga or jogging.

Although I do not know the reason, I suddenly get sick as if I have a seizure. Things such as stress, fatigue and low pressure could work as triggers.

I am hesitant to make an appointment because I am worried that I might suddenly feel ill and end up canceling it at the last minute.
