1. heart disease
Heart disease has been the leading cause of death in India for more than two decades, driven by unhealthy diets that lead to high blood pressure, accumulation of fats in the blood (plaques) within the artery walls, lethargy, obesity and smoking.
2- Chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease, including pulmonary hypertension, occupational lung disease and interstitial lung disease, causes irreversible damage to the airways and other lung structures to reduce respiratory capacity. Lung disease is not curable, but it can be controlled with treatments that widen the main airways and improve shortness of breath. Smoking, air pollution, occupational chemicals, dust, and frequent lower respiratory infections exacerbate lung disease.
Diarrheal diseases are one of the main causes of death for children under the age of five, killing between 800,000 and one million children, entering 900,000 children and causing 327,000 clinic visits every year. The addition of a rotavirus vaccine to India's comprehensive vaccination program in 2016 to protect children from the leading cause of acute diarrhea in young children helped bring down numbers quickly.
Stroke, which was ranked the sixth leading cause of death in 2005, has become the fourth leading cause of death in India. Risk factors for stroke, also known as cerebral vascular disease, are the same as for heart disease, but the disability caused by stroke is usually greater, as it can cause partial or complete paralysis.
5. Infections of the lower respiratory tract
With better prognosis and management of infection, lower respiratory infections such as pneumonia, lung abscess, and acute bronchitis have regressed to a single location as the fifth leading cause of death. It is one of the most common infections in the elderly and people with reduced immunity to other infections, such as seasonal flu. Symptoms include shortness of breath, weakness, fever, cough and fatigue that lasts for more than a week.
