Hi All! So I posted here a year or so ago, thinking I definitely had reactive hypoglycemia. My symptoms were very similar to diabetic lows but without actually getting low blood sugar. I've since been diagnosed with POTS, which is a type of orthostatic intolerance. In essence, when I stand, my heart rate sky rockets, and my blood pressure does as well (though most people have their blood pressure drop, there is hyper and hypo POTS). The symptoms are pretty much match typical low blood sugar symptoms: racing heart, clammy, sweating, feeling weak, shaking, irritable, dizziness, etc etc. It's also easy to think it's related to food, because symptoms are alleviated by high salt intake. Sweet, high refined carb foods tend to be lower in salt, so it's easy to see a pattern with higher sugar and more symptoms. The test is simple. Using a blood pressure monitor, you check your heart rate and blood pressure while lying down for ten minutes or so, then stand up and test every minute or so for ten- fifteen minutes. (Google poor man's tilt table test for POTS for more directions). I went to a cardiologist after seeing that my stats qualified me for a POTS diagnosis, and was advised to dramatically up my salt intake (it's caused usually by low blood volume and salt increases your blood volume). Since then (Nov 2021) I haven't had a single episode of those horrid symptoms. Just putting this out there in the hopes of helping someone searching for answers like I was!
