Is it normal to suffer from prolonged nausea years after "recovery"?

I was diagnosed with an eating disorder in 2020. In reality I had it for years before it was noticed. But in 2020 something arguably even worse began. Roughly at the same time I got diagnosed, I started suffering from nausea that very quickly turned chronic. I've had it for 5 years now. It has reduced massively from the worst times, but it's still there. Is this normal or has the same happened to anyone else? I assume these things are somewhat correlated or linked.
