DAE get sick twice as often now?

I’m 24 and I remember back in my teenage years, I was getting sick like once every 3 years or even more than that. And not from viruses that I was getting from other people, but from food poisonings from the shitty stuff I ate.

Now I get 3-4 times per year sick. That’s not just double the amount. I’ve done blood tests and everything seems pretty normal besides the insulin resistance that was cause by my PCOS, which I highly doubt has anything to do with the illnesses. Anyway, I’m not sure what’s going on. It seems like Covid fucked me up and I was never the same after that. Ever since I started getting sick so often.
