Fatigue and mood changes may involve thyroid dysfunction, adrenal stress response patterns, blood sugar instability, nutrient depletion, or sex hormone fluctuation. In women, symptoms may include cycle irregularity, PMS, sleep disturbance, weight changes, and hot flashes. In men, low energy, decreased recovery, and mood shifts are common patterns.

Adults throughout the South Hills of Pittsburgh often experience overlapping stress and hormone-related contributors rather than a single isolated cause.
