I'd get a second opinion if something doesn't sit right with you. Doctors are human and they make mistakes too. Nobody knows your own body better than you do. If your gut says something is wrong, keep pushing until you get answers.

I'm not a doctor and you should definitely talk to your physician about this. That said, the general medical consensus seems to be that moderation is key. Most health concerns come from extremes in either direction.

If you don't have insurance, look into a community health clinic. A lot of them charge on a sliding scale based on income. Don't skip care because you're worried about the cost — small problems are cheaper to fix than big ones.

The boring stuff actually works: get enough sleep, drink water, move your body every day, eat more vegetables, don't smoke. There's no magic pill. The companies selling magic pills are the ones making money off people wanting an easy answer.

The evidence on this is actually mixed. Some studies show one thing, others show the opposite. When the science is unclear, I default to common sense: eat a varied diet, exercise regularly, get enough sleep, and don't stress too much about individual health fads.

My advice: don't self-diagnose using the internet. You'll convince yourself you have some rare terrible disease when it's probably nothing. I did this once and worked myself into a panic over what turned out to be a pulled muscle.

I work in healthcare and see this question frequently. The short answer is that individual results vary enormously. What works for one person might not work for another. The best approach is to work with your doctor to find what's right for your specific situation.
