If you are experiencing shortness of breath and palpitations, you should consult with a doctor as soon as possible. Depending on the severity of your symptoms, the doctor may refer you to a cardiologist, a pulmonary specialist, or an emergency room. If your symptoms are mild, your doctor may recommend lifestyle changes such as quitting smoking, avoiding alcohol and caffeine, managing stress, and exercising regularly. You may also need to take medication to reduce the palpitations and/or shortness of breath. If your symptoms are severe, your doctor may recommend additional tests to diagnose and treat the underlying cause. In any case, it is important to seek medical attention so that you can get the care you need to improve your health.
