most helpful answer so sorry you're going through this. it sounds scary. even if your blood sugar levels tested normal during a routine lab test that doesn't mean you're not having episodes of hypoglycemia. when you say "my sugar levels are normal when checked " i'm assuming you're talking about a lab test. have you ever used a hand-held glucometer to have someone check your sugar level when you experience one of these shaking/sweating/passing out episodes? the reason your doctor specifically said to eat something sugary when this happens is to rapidly raise your low blood sugar levels. it's not enough to eat just anything when these episodes occur. carry a candy bar or something very sugary with you to eat when you start to feel these symptoms coming on. passing out for over an hour can indicate dangerously low blood sugar levels. you should not allow that to continue. if you experience an episode like this again and your friends cannot rouse you (wake you up) they need to call 911 immediately. i would strongly recommend going back to the doctor to have your symptoms reevaluated if eating sugar isn't helping when you have one of these episodes. by the way your blood pressure and pulse numbers look very good which is why your doctor wasn't concerned. i hope this helps!
when i dont eat for more than 3 hours i shake get hot flashes and pass out. my sugar levels are normal when checked. uptaking sugar when this happens was my doctors advice but it doesn't always help. if i don't eat within ten minutes of this shaking and hot flashing then i pass out for over an hour. my blood pressure is lower and so is my pulse. my daily resting rate is 104/71 and hr of 58-65. neither of which my physician was concerned with. my temperature runs in the normal from 96-97 f. shaking intensifies if i use my muscles. when resting i fell no shaking only if i move. . why?
