Christi85 24 Posted January 4, 2014 I'm 3 weeks post op. It's happened twice now. I'll wake up, start getting dressed for the day and suddenly get hot and weak. I felt like I was going to pass out at any given moment. I had to lay back down for about 30 minutes and sip on Gatorade. Awful feeling. Share this post Link to post Share on other sites

mamaplumlee 58 Posted January 5, 2014 Sounds like dehydration with possibly low blood pressure from said dehydration. I still get orthostatic if I get behind or when I first stand up. Share this post Link to post Share on other sites
