Have a hypothesis that medical testing is finding illnesses so we never go off their market

My mother is diagnosed with Grade 4 liver damage today. She also has Type 2 diabetes which "does not subside"

She doesn't eat any sugars, cut out starch, very very occasional outside/packaged food, no alcohol, has been working (job and household), works around clock in the house Taking allopathic medicines for diabetes, now may start diet restrictions for Liver damage too

Strongly feel she is being mis-diagnosed. The hospitals and diagnostic centre are trying to milk healthy people too. How else do you keep up revenue

Have you faced similar situations? What can be done here?

P.S. Most of the doctors we have met are big C, the ones who sound genuine are the ones not treating 😪
