What primary symptom of postpartum blues can lead to increased anxiety and restlessness?

Mood swings are a primary symptom of postpartum blues that can significantly impact a new mother's emotional stability. These fluctuations in mood can lead to feelings of heightened anxiety and restlessness, which are common in the postpartum period. The underlying hormonal changes, lack of sleep, and the emotional adjustment to motherhood contribute to these mood swings.

When experiencing mood swings, a mother may go from feeling happy and excited about her new baby to suddenly feeling sad or overwhelmed. This unpredictability can create a sense of anxiety because she's unable to control or predict her emotional responses. As a result, she might feel restless, as these emotional fluctuations can make it difficult to focus or find a sense of calm.

Other symptoms, such as appetite changes, headaches, or physical fatigue, can contribute to discomfort and stress but do not directly correlate with the anxiety and restlessness that mood swings can provoke. Mood disturbances manifested as swings between different emotional states are particularly salient in the context of postpartum mental health.
