Which of the following is a sign of trouble indicating potential mental health issues?

Loss of appetite is considered a sign of trouble that may indicate potential mental health issues. Changes in appetite, particularly a significant decrease, can be linked to various mental health conditions, such as depression or anxiety. When someone experiences distress or emotional upheaval, it can manifest in physical ways, including a lack of interest in food. This can also lead to further health complications if not addressed.

In contrast, increased social engagement, improved performance at work, and heightened energy levels typically suggest positive emotional states and mental well-being. While it's essential to consider individual circumstances, these behaviors generally do not indicate a decline in mental health and are often seen as signs of stability or improvement. Recognizing signs such as loss of appetite is crucial for early identification and intervention in mental health concerns.
