Question: My daughter is 55. She has had several episodes, but a recent one was the most severe. She collapsed, arms went numb, vomiting, difficulty talking and EMT said her blood pressure was 80/35. The next day she felt tired and today she feels fine and sounds fine. She cannot get to her MD before November 30. What are possible causes of her symptoms?

Sorry, but I cannot be very informative. My daughter has chronic low blood pressure and tends to be hypoglycemic. She drinks coffee and eats small snacks frequently. I do not know if she takes any medication aside from treating our familial tendency for osteoporosis.
With this last episode, that concerned me so much, the emergency room ran numerous tests and found nothing significantly abnormal. Her blood pressure returned spontaneously to her normal range before they discharged her. Today she says her energy is returning and she feels fine.
Of course, I do not expect you to give me a definitive diagnosis. I want to know what diseases can cause the reactions she experienced. I suspected her electrolytes were imbalanced for some reason.
