Anxiety can lead to heartburn, and patients may subjectively feel a sudden increase in heartbeat. Anxiety can also lead to dry mouth, shaking limbs, sweaty palms, shortness of breath, or frequent trips to the bathroom, and even dizziness, fainting and other symptoms of autonomic dysfunction. Anxiety can lead to panic, but panic should first go to the cardiology department for an electrocardiogram to rule out arrhythmias or other causes of panic. In addition, anxiety can have an effect on blood pressure and blood sugar. If particularly anxious, it can lead to higher blood pressure and anxiety can cause more physical discomfort with related symptoms.
