What makes you think that reducing these metrics would make any difference to your health? If they are sometimes correlated with high risk that doesn't mean they cause high risk, or that the risk is significantly altered if they are lowered. Doesn't your lack of medical training worry you when attempting a diagnosis?

It's certainly reassuring to feel you can do something, but beyond the general advice given to you to eat healthily and watch for symptoms, perhaps there is nothing you can do if you are genetically predisposed to problems?
