What is the most common anxiety disorder that may require hospitalization?

Panic Disorder is the most common anxiety disorder that may require hospitalization due to the acute and often debilitating symptoms individuals experience. This disorder is characterized by recurrent, unexpected panic attacks that include physical symptoms such as heart palpitations, shortness of breath, dizziness, and feelings of impending doom. These intense episodes can lead to significant distress and a fear of future attacks, which might impair a person's ability to function in daily life.

Individuals suffering from Panic Disorder may develop agoraphobia, which further complicates their condition and can lead to isolation or an inability to engage in everyday tasks. Because of the severity of symptoms and the risk of self-harm or suicidal ideation that can arise during a panic attack, hospitalization may be necessary to stabilize the patient, provide intensive treatment, and ensure safety.

In contrast, while Generalized Anxiety Disorder, Social Anxiety Disorder, and Specific Phobias can also be serious and debilitating, they typically do not manifest with the same level of acute distress and physical symptoms as Panic Disorder. As a result, hospitalization is less frequently required for those disorders compared to Panic Disorder.
