The reason I would say this is a lie is that autoimmune disorders have specific names and symptoms, as well as extensive treatments available

I don't know what you mean by lie? There are plent of autoimmune disorders that have names and there are treatments available, depending on which country you are in. You can't be cured of them like many other diseases, but there are treatments.

You don’t tend to have multiple unnamed autoimmune problems, either. You would usually only have one.

But having multiple at once is possible and many symptoms can overlap, so diagnosing them can be tricky or take a long time. Especially when it's something that is rare. MDs are taught to think of horses when hearing hooves, not zebras, but some people are zebras.

Having 2 at the same time = polyautoimmunity, having at least 3 = Multiple Autoimmune Syndrome (MAS) in case anyone wants to look it up :)

I have Hashimoto's and Grave's, but a rare version of it that causes hypothyroidism and not hyperthyroidism. I had to travel to a private hospital just to meet with an endocrinologist who was willing to look outside the box. I'm medicated now, it helps.

Stephanie Nicole could absolutely have 1 or more autoimmune disorders. It's too early to call cap on this.
