Anxiety is a natural response to stress or perceived danger and is often associated with fear and worry. If you’re feeling anxious, you may experience physical symptoms, such as sweating, shaking, nausea, or muscle tenseness. These symptoms may become excessive or persistent if you have a generalized anxiety disorder (GAD), and may affect blood pressure, just as chronic high blood pressure or hypertension may in some circumstances cause feelings of anxiety.
