What is a key indicator of postpartum depression?

Persistent feelings of sadness are a key indicator of postpartum depression. This condition often manifests after childbirth and can significantly affect new mothers. While it is normal to experience a range of emotions after giving birth, postpartum depression is characterized by a more profound and enduring sense of sadness that can impair a mother's ability to care for herself and her baby.

This feeling of sadness is often accompanied by a variety of other symptoms, such as withdrawal from social interactions, irritability, anxiety, and changes in sleep patterns. Recognizing these persistent feelings is crucial for early identification and intervention, which can lead to improved outcomes for both the mother and her child.

In contrast, the other options suggest positive emotional or physical states, which do not align with the clinical presentation of postpartum depression. Increased energy levels and heightened interest in activities indicate a more positive mood, while rapid weight gain could relate to other health issues or conditions but is not a specific indicator of postpartum depression itself.
