Hi Doctor, A week ago, my housekeeper who is 48 years old, was working in the garden and she started vomiting non stop for few hours and felt dizzy. She continued vomiting until the next day, continued feeling dizzy and she didn t have an appetite to eat. She was in bed for 2 day, couldn t left her head up. I found out from her that she stopped taking her blood pressure medication a year ago. When we measured her blood pressure it was high. She started taking her blood pressure medication after a year from stopping to take it. It has been a week, however she still feels dizzy and a bit weak. What could the cause be? Thanks. Rania
