Health Condition


About This Condition

Anxiety describes any feeling of worry or dread, usually about events that might potentially happen. Some anxiety about stressful events is normal. However, in some people, anxiety interferes with the ability to function.

Some people who think they are anxious may actually be depressed. Because of all these factors, it is important for people who are anxious to seek expert medical care. Natural therapies can be one part of the approach to helping relieve mild to moderate anxiety.


Physical symptoms of anxiety include fatigue, insomnia, stomach problems, sweating, racing heart, rapid breathing, shortness of breath, and irritability.

Other Therapies

Underlying medical conditions, such as excess hormone secretion from the thyroid or adrenal glands, should be treated when present. Psychological counseling often accompanies drug therapy.
