Question: Blood pressure and h20 intake.


 debrann222 - Fri Feb 29, 2008 4:35 pm

My 'normal' blood pressure with 40mg Lisinopril and 25mg HCTZ is 140/90. I just started a diet and increased my water consumption from practically nothing to 64-80 oz a day. After the 2nd day, I fainted 6 times and my blood pressure was 76/45. I went to the Dr and he told me to take half my usual lisin. dose and see what happens. I've been monitoring my BP for 2 days now and the highest its gone is 115/75. Could this be due to the sudden increase in water? I've also cut down on adding salt to foods.

Thank-you!

User avatar Hello Debrann222,

Often, an increase in water may actually increase blood pressure; however, decreasing salt intake can sometimes have dramatic effects on blood pressure reduction. Exercise also can reduce blood pressure.

Overall, I suspect that your healthier lifestyle is having beneficial effects on your blood pressure. I would add that not many people actually accomplish lifestyle changes to help improve their health (which is why so many people end up on high dose medications) so I applaud your accomplishments.

Best wishes.
