Cardiovascular disease (CVD) refers to a range of conditions affecting the heart and blood vessels, with conditions like heart attacks and strokes being common examples. Lifestyle factors contributing to CVD include a poor diet, lack of physical activity, tobacco use, and excessive alcohol consumption. High blood pressure, high cholesterol, and obesity are also significant risk factors. Making positive lifestyle changes, such as adopting a balanced diet and increasing physical activity, can help reduce the incidence and severity of cardiovascular disease.
