Feel Like Yourself Again
Hormone imbalances can impact both women and men, leading to a range of frustrating symptoms like fatigue, mood swings, low energy, and changes in physical health. Whether you’re navigating menopause or experiencing andropause (age-related hormone decline in men), Dr. MacIsaac offers personalized bioidentical hormone replacement therapy (BHRT) to restore balance and improve your quality of life.
How does BHRT hormone therapy work?
Bioidentical hormone replacement therapy (BHRT) hormone therapy works by rebalancing the hormones your body needs to function at its best. For women, this can mean addressing imbalances in estrogen and progesterone related to menopause. For men, BHRT commonly involves supplementing testosterone levels to alleviate the symptoms of andropause.
Hormones act as the body’s chemical messengers, controlling almost every major function. When hormone levels are low or imbalanced, it can disrupt everything from your mood to your energy levels. BHRT uses natural, plant-derived hormones that mimic your body’s own to safely and effectively address the root causes of hormonal imbalances, not just the symptoms themselves.
