Mood Instability

Meaning

Mood instability is the clinical description of rapid, exaggerated, and unpredictable shifts in a person’s emotional state, extending beyond normal emotional fluctuations. These changes can manifest as abrupt transitions between states such as euphoria, irritability, anxiety, and depression, often significantly impairing daily function and quality of life. In the context of hormonal health, mood instability is frequently observed during periods of significant hormonal flux, such as perimenopause, premenstrual syndrome, or with imbalances in thyroid or adrenal hormones. It is a common symptom that necessitates careful endocrine and psychological evaluation.
