Mood swings refer to rapid or intense shifts in emotional state, ranging from sudden irritability and sadness to feelings of high energy or anxiety. While daily emotional changes can happen, often linked to stress, fatigue, or minor life events, frequent or dramatic shifts can significantly impact relationships, work, and overall quality of life.

In women, mood swings are frequently associated with hormonal changes due to the menstrual cycle (PMS/PMDD), pregnancy, perimenopause, or conditions like PCOS and thyroid imbalances. However, they can also be a key indicator of underlying mental health conditions like Anxiety or Depression.
