Essential Pathology with Clinical Correlation of NonCommunicable Diseases

Introduction
Non-communicable diseases (NCDs) are chronic disorders that are not transmitted from person to person and are characterized by prolonged duration, slow progression, and complex multifactorial causation. Unlike infectious diseases, NCDs develop gradually over years as a result of interactions between genetic susceptibility, environmental exposure, metabolic abnormalities, and behavioral risk factors. They represent the leading cause of morbidity and mortality worldwide and constitute a major challenge for healthcare systems, particularly in low- and middle-income countries
undergoing epidemiological transition. The increasing prevalence of
NCDs is closely associated with urbanization, aging populations,
sedentary lifestyles, unhealthy dietary habits, environmental pollution, and psychosocial stress. These diseases frequently remain asymptomatic during early stages, allowing pathological damage to accumulate before clinical manifestations become evident.
Understanding the pathological basis of NCDs with clinical
correlation is therefore essential for early diagnosis, prevention, and effective management.
