What is the leading cause of death worldwide?

As of 2012, cardiovascular disease is the leading cause of death worldwide. It accounts for three out of every 10 deaths, with millions dying from ischaemic heart disease or from strokes.

Tobacco use is a primary cause of cardiovascular disease, chronic obstructive lung disease and lung cancer. Tobacco is a contributing factor for every one out of 10 deaths worldwide.

Some ways of preventing heart disease is to get active by doing at least two hours of physical activity a week, eating a healthier diet, managing blood pressure and blood sugar, and quitting smoking. Losing as little as three percent body weight reduces the risk of heart disease.
