Although decreases in a woman’s production of certain hormones, particularly estrogen, progesterone, and thyroid levels are more likely to occur as they approach menopause; hormonal imbalances may cause symptoms at any age. These changes can result in menstrual irregularities, infertility, low sex drive, weight changes or alterations in mood and energy levels. A comprehensive history in conjunction with simple lab tests can often discover hormonal causes for symptoms that interfere with daily life. Options for managing these conditions may exist and often will greatly improve the quality of life for most women.
