Hypertension is the most prevalent chronic ailment in India. According to the National Health Profile (NHP) 2019 data, of all the patients who visited government clinics in 2018, 6.19% of the people were diagnosed with hypertension. It is higher than the people diagnosed with diabetes, the next prevalent chronic disease in India, which accounts for 4.75%. However, the numbers could be an underestimation, since the NHP does not assess people who visit the private clinics.
