Full Answer

Doctors do not know the exact cause of most anxiety disorders, as of 2015, according to Mayo Clinic. Traumatic events can trigger anxiety, or some people may have genetic traits that contribute to anxiety. An underlying medical condition may cause anxiety. Medical conditions associated with anxiety include drug withdrawal or abuse, heart disease, asthma and diabetes. Other health issues that may cause anxiety include thyroid problems, irritable bowel syndrome, some tumors and pre-menstrual syndrome.

If anxiety becomes difficult to manage and interferes with social or professional occurrences, a doctor may be able to help, notes Mayo Clinic. It is important to see a doctor if other stressful feelings, such as depression, worry or fear, accompany the anxiety. If the anxiety is due to drug or alcohol abuse or a possible underlying health problem, it is important to seek medical advice. If anxiety causes suicidal tendencies, immediate medical attention is necessary. Anxiety may worsen over time, so early treatment is ideal.
