Introduction
Once associated with aging, lifestyle-related illnesses are now common among millennials and Gen Z. Sedentary behavior, unhealthy diets, and relentless stress are making young adults more vulnerable to serious health issues. These common diseases in young adults are rising silently, often undiagnosed until significant damage occurs.
According to recent studies, chronic diseases in young adults are responsible for increasing medical costs, lost productivity, and even early mortality. It’s no longer a distant concern — it’s a pressing reality.
