Limited healthcare facilities, shortage of medical personnel, and lack of awareness contribute to the persistence of communicable diseases. Strengthening the healthcare infrastructure and improving access to medical services are essential for effective disease control.
What are Non-Communicable Diseases?
Non-communicable diseases (NCDs) are chronic conditions that are not transmissible between individuals. They include diseases such as cardiovascular diseases, diabetes, chronic respiratory diseases, and cancer. NCDs are becoming increasingly prevalent in Kerala due to lifestyle changes, an aging population, and environmental factors.
Common Non-Communicable Diseases in Kerala
Here is the list of some non-communicable diseases in Kerala:
1. Diabetes
Diabetes is a growing concern in Kerala, with a prevalence rate of around 20% among adults, according to recent health surveys. The increase in diabetes cases is linked to changing dietary patterns, high rates of obesity, and sedentary lifestyles. Kerala has one of the highest diabetes prevalence rates in India, making it a significant public health challenge.
2. Chronic Respiratory Diseases
Chronic respiratory conditions, such as asthma and chronic obstructive pulmonary disease (COPD), are prevalent in Kerala. Urban air pollution, caused by vehicular emissions and industrial activities, exacerbates respiratory problems. Studies show that air pollution levels in cities like Kochi and Thiruvananthapuram exceed national standards, contributing to a higher incidence of respiratory diseases.
3. Cardiovascular Diseases
Cardiovascular diseases, including heart disease and stroke, are the leading causes of morbidity and mortality in Kerala. The rise in cardiovascular diseases is attributed to factors such as high blood pressure, high cholesterol levels, and sedentary lifestyles.
