Sorry I’m late. I’m really wouldn’t read the cleveland clinic article which is not a very good source.
I have POTS. The simplest way to accomodate for your partner is simply to listen what she needs and be mindful about what tends to affect her condition. Also while some treatments help some people with POTS there is no widely recognised (FDA-approved treatment) so dont expect her to get better, it’s also usually a lifelong condition. POTS is a very common condition in Long COVID, so if your partner had COVID 6 months or less before her POTS started, she will fit long COVID diagnostic criteria too. The POTS label will be more useful than the long COVID label, as long COVID is a label for any chronic illness triggered by COVID.
The most important thing for you to know is POTS primarily affecting women, and it is not regularly taught in medical schools. Some medical doctors, especially overworked or patriarchal ones, will likely not take the diagnosis seriously and blame her illness on “anxiety” or “functional neurological disorder” (the modern euphemism for hysteria), so make sure to steer clear of those doctors if you do encounter them.

If you want to get into the science, recent research suggests POTS isn’t a very useful distinction from regular orthostatic intolerance. So the POTS label may not stand the test of time. The illnesses included under the POTS label are likely not correlated with tatychardia, which is what the entire idea the clinical concept of POTS is based around. Hopefully, further research will shine light onto this. https://mecfsskeptic.com/the-problems-with-pots/
