Some of the states where the incidence of diabetes was found to be higher than the national average include Goa (33.7 per cent), West Bengal (28.2 per cent), Assam (34.6 per cent) and Odisha (27.2 per cent).

Diabetes and hypertension

Diabetes is a disease in which the body’s ability to produce or respond to the hormone insulin is impaired, resulting in abnormal metabolism of carbohydrates and elevated levels of glucose in the blood.

While hypertension also known as high blood pressure is a long term medical condition in which the blood pressure in the arteries is persistently elevated.
