I have a problem every time I take antibiotics for recurring bronchitis.

At first I feel great but then I get stomach bloating and shortness of breath, even though my oxygen saturation is fine.
I get other weird symptoms too, like dizziness and fatigue.

I get short of breath and then I get terrible panic attacks.

I've gone to the doctor or hospital in the past and they just run expensive tests on me and then tell me I need prozac and that it's all in my head.

I read about something called SIBO and I'm wondering if that's not what I have. I guess the antibiotics mess up your gut flora and cause a lot of trouble.

I'm asking you folks what I should do because so far the doctors have been useless.

Thanks!
