I have felt dizzy on 4 or 5 occasions today. I took my blood pressure a few times and it varied quite widely. The worst was 181/106, and the best was 132/101. There were 8 measurements in all but they were all quite different. I am quite overweight and I do virtually no exercise. I was a top flight athlete in my youth but have done nothing for years. I had my first alcoholic drink for months last Friday, but in the past I have drunk more than I should. I know I need to exercise, lose weight, eat and drink better etc etc, and I am making a conscious effort that I will - but I just need to know - should I be worried about this dizziness enough to go to the emergency room of the hospital now - or do you think I will be OK?
