It is challenging to distinguish typical pregnancy concerns from a more serious anxiety disorder. Recent studies indicate that antenatal anxiety may be even more common than depression, which points to an important area for exploration. There are many possible causes of anxiety during pregnancy, with symptoms ranging from mild emotional feelings of uneasiness to severe panic and physical symptoms that mimic life-threatening conditions. As options for treatment vary, it is important to weigh the risks of treatment with medication against the risks of uncontrolled anxiety before a decision is made regarding management. Antenatal anxiety is an important issue that needs further research, and it is essential that nurses be aware of the current literature to properly care for patients using evidence-based practice.
