Background: Internal diseases pose a significant public health concern due to their prevalence and impact on premature mortality and disability. This study investigates the role of internal diseases in the morbidity structure of the Republic of Kazakhstan’s population, focusing on the period from 2019 to 2021. Objective: The primary objective of this study is to assess the prevalence and dynamics of internal diseases among the adult population of the Republic of Kazakhstan during 2019-2021. Methods: We conducted a comprehensive analysis of medical records from healthcare facilities across the Republic of Kazakhstan for the years 2019 to 2021. The study focused on diseases of the cardiovascular system, endocrine system, metabolic disorders, respiratory system, gastrointestinal tract, and urinary system. Epidemiological indicators, including prevalence rates and morbidity, were calculated for each disease category using official population data for the same period. Results: Our findings indicate a noteworthy increase in the prevalence rates of internal diseases among the adult population of the Republic of Kazakhstan from 2019 to 2021. Diseases of the cardiovascular system were the most prevalent, with arterial hypertension and coronary heart disease being particularly pressing concerns. Diabetes mellitus and thyroid abnormalities were the most common endocrine organ diseases. Among respiratory diseases, bronchitis had the highest prevalence, followed by tracheitis, bronchial asthma, and pneumonia. Additionally, the prevalence of gastrointestinal tract diseases increased by 3% over two years. Conclusion: This study underscores the urgent need for effective prevention and management of internal diseases in the Republic of Kazakhstan. The increasing prevalence rates across all leading categories of diseases highlight significant public health concerns.
