Orthostatic intolerance and sleep apnea?
Im age 34 with lifelong undiagnosed Orthostatic intolerance and also lifelong sleep apnea (16 RDI/h).
I get about 25-40 elevated heart rate and 25-30 elevated diastolic blood pressure when standing up in the Schellong test.
I wonder if these conditions can be connected?
Standing up: I usually feel weak and dizzy if I stand upright and still for too long, for example if I’m lined up in a queue I will get uncomfortable after about 5 minutes and either crouch/squat or walk around to get relief.
Sleep: I often wake up feeling wired and jittery, as if in fight and flight. And my average heartrate while sleeping (65-70) is often higher than resting daytime (60).
I’m currently pursuing sleep apnea treatment (expansion + jaw surgery) because didn’t notice much relief from PAP.
I wonder if there’s any tests or specialists I should see to get the mechanism and causes of the Orthostatic intolerance more analyzed?
