So for the past like six to eight months my vision will go black after standing up or I become extremely dizzy and nauseous. I have talked with my primary care doctor and a few of my other doctors the only thing they can find wrong is that my heart rate is high and my bp is low. Any suggestions
It sounds like me before I was diagnosed with Postural Orthostatic Tachycardia Syndrome (POTS). I was having episodes when is go from one position to another, standing, sitting, lying down, and even just bending over & straighten up. They did the tilt table test like AmbrielleLyn mentioned. What happens to me is as I stand my blood pressure drops drastically, which causes my heart rate to speed up trying to pump more blood from my legs back to my heart & into my brain (hence the blacking out feeling). I had really low BP normally, so they've put me on BP meds to increase it in order to compensate & control the POTS. I still have to stand slowly though. Ask for a tilt table test! I also have blood sugar issues and when I start to feel light headed &/or shaky I eat a granola bar. Hugs love & prayers you get answers soon. 🙂❤🙏🌼
When you get up from a sitting position flex and tighten your buttocks muscles. There are a lot of large blood vessels around this area, and tightening the muscles contracts the vessels, forcing a rise in BP everywhere else, I do it everyday. It has helped tremendously.
