The four main NCDs are caused, to a large extent, by four modifiable behavioural risk factors: tobacco use, unhealthy diet, physical inactivity and harmful use of alcohol. These unhealthy behaviours lead to four key metabolic/biological changes that increase the risk of NCDs: raised blood pressure, overweight/obesity, high blood glucose levels/diabetes, and hyperlipidemia (high levels of fat in the blood).
