Most people do not get gaslit with one big lie.
They get gaslit with one small dismissal at a time.  
Dr. Chris Renna, DO is the founder of LifeSpan Medicine and one of the earliest pioneers in prevention-first care. Long before longevity became a trend, he was already practicing it. 
In this episode, he and I break down what gets missed when healthcare is reactive, rushed, and reduced to one symptom at a time.
If you have been told you are fine while your function is clearly declining, this conversation is for you. They cover why normal labs do not mean optimal health, why prevention and lifestyle are treated as extras instead of essentials, and what it actually looks like to approach aging with strength, clarity, and independence.
Medical gaslighting does not always happen with one big lie. It happens with small dismissals, repeated over time. You do not have to wait until things fall apart to be taken seriously.
