Yes, as a matter of fact I do

I don't get this due to my POTS, but early on and during bad flares, my symptoms were enough to make me anxious - and that gave me stomach aches lol doesn't happen to much anymore but, tis possible (also I've heard lots of POTS patients have bowel issues comorbid, as well as just dysautonomia gut issues)

Sometimes POTS and IBS can be comorbid conditions so you might be developing IBS symptoms. I have both and I have noticed that my stomach gets more irritated when I am in hot environments or during a pots flare.

Pots can cause problems with digestion, and it's also common to have other conditions with pots that cause stomach problems- like ibs or ibd

My kidney function dropped 40% since the Pots started. Kidney stones started. And nausea due to lack of blood/oxygen. All 3 cause different forms and degrees of stomach pains. For me. I can test a number of things by seeing if it gets better or worse after sitting woth knees up for an hour or 2.

Yes someone tell me why my stomach hurts and i feel dizzy every time i eat

If you find something on the reducing localized sporatic sweating, let me know. That and non-time related, short spans of overheating are easy to rectify after the fact, but i havent seen anything useful for minimizing the occurences. But yes, ill take inconvient over nausea any day. Nausea can too quivkly lead to vomiting and the imbalances that causes.

I have a lot of the gastro symptoms that people complain about with POTS along with a bunch of others. Sometimes saltiness help a bit

Yes. Especially when compounded with anything else. For me, a 2 hour dental crown caused huge aftereffects for a whole month (low spO2, very low heart rate at night were the most alarming, but also the nausea, inappropriate sweating and tachycardia, bowel issues, and even my first kidney stones. Then just recently, a very very minor surgery and allergic reacting to the 1 inch of surgical glue, caused painful rash, but also extreme chemo like nausea, very bloated abdomin, poor urination, and slow/stopped of intestines. I thought maybe got another kidney stone (regular thing now last 18 months), but all clearing as soon as glue removed.
