Which of the following is a common symptom of anxiety in patients?

Restlessness is a common symptom of anxiety in patients, as it often reflects the heightened state of arousal and tension that accompanies anxiety disorders. Individuals experiencing anxiety may find themselves unable to sit still or may feel a constant sense of unease, leading to fidgeting, pacing, or an overall inability to relax. This physical manifestation of their mental state can be a significant indicator of their anxiety level.

On the other hand, increased appetite is typically not associated with anxiety; many individuals may experience a decreased appetite due to their heightened nervousness. High energy levels might suggest a positive mood or excitement rather than anxiety, which usually involves fatigue or lethargy due to excessive worry or panic. Improved sleep patterns also do not align with anxiety, as individuals suffering from anxiety often struggle with insomnia or disrupted sleep, marking restlessness as a prominent symptom instead.
