Lifestyle Diseases: The Complete Guide

Lifestyle diseases — conditions driven largely by daily habits rather than infection or genetics alone — now account for the majority of deaths worldwide. The encouraging part: because they’re driven by behavior, they’re also largely preventable and, in early stages, often reversible.
