Dating someone with POTS. What to expect?

Hello, I am quite uneducated on this subject, but I went on a first date with someone who told me she has POTS. I really, really like her, like best first date I’ve been on. I just really have no clue what I’m getting into, and apologies if the fact that this all gives me pause is offensive.

She doesn’t drink or smoke and sticks to a very low carb diet and feels pretty good most of the time due to those precautions. Not an issue for me, I don’t even really like drinking and am more of a stoner.

However, I really like exercising and hiking and playing tennis and stuff like that and I want to share those hobbies with my partner. For example want to thru hike the Appalachian trail, and I don’t need a S/O to be with me the whole time but coming along for a day or two here and there would be cool. I’ve read a bit on here and it seems exercise is kind of difficult for folks with POTS, and it seems that outdoor exercise (hiking) could be downright dangerous with the possibility of fainting and whatnot.

I know I should just talk to her about this stuff, but I don’t want to sound like a completely uneducated idiot or say something offensive. And again apologies if I’ve said anything offensive here.
