Hormones are chemical messengers that control virtually every process in your body. From regulating your metabolism and energy levels to influencing your mood, sleep, fertility, and weight, hormones work behind the scenes to keep everything running smoothly. When hormone levels become imbalanced, the effects can be far-reaching and significantly impact your quality of life.
Many people live with hormone imbalance symptoms for years, attributing them to stress, ageing, or simply "how things are." However, recognising these symptoms and seeking appropriate testing can lead to treatments that dramatically improve how you feel.
