Obese people are at risk of developing lifestyle disorders like diabetes, hypertension, cholesterol abnormalities. These cumulatively increases the risk death from cardiovascular disease (angina, heart attacks, heart failure)

There is a strong genetic or familial element in obesity. There is always a history of a first or secondary degree relative struggling with obesity. Obesity is also associated with a family history of other life style disease like diabetes, hypertension and cholesterol abnormalities.
