Anxiety is a normal response to threat, but it becomes a disorder when worry or fear is persistent, disproportionate and interferes with work, study or relationships. Common forms include generalised anxiety, social anxiety, panic disorder and phobias.
Physical symptoms such as racing heart, chest tightness and stomach upset frequently lead people to search for medical causes first. Effective treatment includes psychological therapy, lifestyle measures and medication where indicated. A GP consultation is the entry point, including preparing a mental health care plan for rebated psychology sessions.
