About
Who I am
I’m Christian Aguiar, a physician trained at UFRJ in Rio de Janeiro (2002), and I tend to think about human health as applied physiology before I think in labels. At 36, after reversing my own hypertension, obesity and pre-diabetes without medication, I found in Functional and Precision Medicine the frame that ties physiology, metabolism and clinical practice to the way my brain actually works.
I practice medicine the way one studies systems: tracing mechanisms, running hypotheses on myself first, and translating evidence into decisions a real person can take on a Monday morning.
What christian.md is
christian.md is the public wiki of my clinical and scientific reasoning. It’s not a clinic, not a social feed, not a newsletter. It’s the place where I make how I think visible — about metabolism, mitochondria, longevity, the microbiome, sleep, exercise, and the rest of the human body — with the mechanisms I believe I understand, the evidence supporting each decision, and the uncertainties that still bother me.
Each entry is an atomic note: a concept, a pathway, a biomarker, a protocol. Each essay is a longer argument about a question I haven’t fully answered. Each pillar is a synthesis of a large theme, with linkable questions and answers.
Commitments
Three explicit rules govern what goes in here:
- Zero prescription. This wiki does not diagnose or prescribe. Public information does not replace a clinical encounter.
- Zero affiliation. No affiliate links, no sponsorship, no course to sell.
- Personal voice, epistemic posture. What I know, I mark as
high confidence. What I suspect, I mark ashypothesis. What I don’t know sits under “Open Questions”. Confidence is explicit, not rhetorical.
