What causes a high sys?

A high systolic blood pressure (sys) can be caused by several factors, including increased cardiac output, high blood volume, or resistance in the arteries due to narrowing or stiffness. Lifestyle factors such as obesity, lack of physical activity, high salt intake, excessive alcohol consumption, and smoking also contribute. Additionally, underlying health conditions like Diabetes, kidney disease, and hormonal disorders can elevate systolic pressure. Stress and genetic predisposition may also play a role in developing high systolic blood pressure.
