10 Common Symptoms of Anxiety Disorder

7. Shortness Of Breath

GAD can cause palpitations, lightheadedness, shortness of breath, and sometimes loss of consciousness. Struggling to breathe properly without physical exertion is a sign of an anxiety attack. In most cases, slow and deep breathing relieves the feeling of shortness of breath. Breathing slowly may feel counterintuitive, but it often works. However, anyone who experiences repeated instances of shortness of breath, palpitations, fainting, or lightheadedness should seek immediate evaluation from a health professional.
