Hormones like estrogen, progesterone, and testosterone play a direct role in regulating mood, and when they fall out of their normal range, emotional stability often goes with them. Women approaching perimenopause frequently notice increased irritability and anxiety as estrogen and progesterone begin to fluctuate, while men with declining testosterone often describe a shorter temper and a harder time managing stress than before.

Thyroid imbalance adds another layer, since both an overactive and underactive thyroid can produce anxiety, restlessness, or a persistent low mood that doesn’t respond to typical stress management techniques. Sleep disruption and chronic stress tend to intensify all of this, creating a cycle that’s difficult to break without addressing the hormonal piece directly.

The National Institute of Mental Health notes that hormonal changes are recognized as a contributing factor in mood-related symptoms, particularly during major hormonal transitions like perimenopause and andropause.

Once hormone levels are tested and corrected where needed, many patients notice their emotional baseline becomes steadier within a matter of weeks.
