I'm an 18 year old male who is planning on learning to Scuba Dive in Egypt. I have the problem that when i get up quickly i get a head rush. this has in the past lead to me fainting but not for the past 18 months. I do get the occasional palpatation, had an ECG but it was fine. i had been previously diagnosed with low blood pressure too.

It's not unusual for people with lowish blood pressure to get this. Basically if you stand up too quickly, gravity pulls the blood into your feet and legs and the blood supply to your brain becomes temporarily insufficient. This gives you a light headed, dizzy sort of feeling. Normally the blood is pumped back to the brain within a few seconds and it all resolves.

As far as diving goes, you just have to be a bit cautious when you stand up fully kitted, as this same situation might occur. Otherwise, you should be fine to try diving out.
