I recently started having high Blood Pressure. My top number is usually normal to prehypertension but my bottom number stays consistently high, stage 1 to stage 2 hypertension. I am only 32 and never had high blood pressure before. My pulse is also constantly high, ranging from 110 to 125 resting. My doctor put me on a diaretic (low dose) a week ago which has lowered my top number more than my bottom. My pulse pressure is now staying between 15 and 30. The good news is I m staying more in the prehypertension range most of the time now, but my pulse is still high and my bottom number still isn t going down as much as I d lile. The only other medication I am on is 75 levothyroxine (have been for years) for my thyroid. I am 5 3 female and weigh 155 - not perfect, but far from terrible. Over the past week I am experiencing moments when I nearly black out or faint. Usually after squatting down then standing back up. I almost blacked out at the store tonight after bending down to get something. I held on to the shelf while everything began to go black and I felt like I was milliseconds away from falling over. This is occurring several times a day and getting worse. Should I be worried about my pulse pressure being low? Pulse rate being high? Diastolic being high while systolic being normal? What could be causing my near fainting spells?
