Dizzy on the stairs

[Thighdentitycrisis]

Over the past week I’ve twice felt like I was going to pass out after climbing stairs. Today when I was getting off the tube and another day recently but I can’t remember where (not at home). I’ve had to stop and hold the wall until it passes then able to carry on as before.

what can it be? I’m fairly fit and not overweight.

Low blood pressure? I think some pharmacies can check it for you then if it's low you can look at what you can do to help? Otherwise inner ear infection?

Low blood pressure? It’s usually high! I’ll get it checked thanks
