hormonal imbalance causes
Hormonal imbalance occurs when estrogen, progesterone, thyroid, cortisol, insulin, or testosterone levels drift outside their healthy range. This guide breaks down the five most common signs — irregular menstrual cycles, persistent fatigue, unexplained weight changes, skin and hair changes, and mood or sleep disturbances — and explains what each may indicate. You'll also learn what causes these imbalances, which symptoms are normal life-stage fluctuations, and exactly when to seek medical testing.
