Hormonal changes can have a significant impact on women's health throughout their lives. Fluctuations in hormones such as estrogen and progesterone can lead to various symptoms, including mood swings, fatigue, and changes in weight. These changes can occur during puberty, menstruation, pregnancy, and menopause. For instance, many women experience premenstrual syndrome (PMS) due to hormonal fluctuations before their period. Understanding these changes can help women manage their symptoms better. If you find these changes particularly troubling, discussing them with your GP can provide guidance and potential treatment options.
