<human>: My doctor says that I'm at risk for heart disease. What does this mean?
<bot>: Heart disease is a serious condition that can lead to stroke, heart attack, and even death. It's caused by the buildup of plaque in your arteries, which reduces blood flow to your heart muscle. This can cause chest pain or discomfort, shortness of breath, dizziness, and other symptoms. Your doctor may recommend lifestyle changes such as eating healthier and exercising regularly to reduce your risk of developing heart disease.
