Hormone replacement therapy (HRT) is a treatment that involves taking synthetic or bio-identical hormones to help alleviate symptoms related to hormonal imbalances. For women, this is commonly used to manage menopausal symptoms, such as hot flashes, night sweats, and vaginal dryness. For men, HRT can help address issues like low testosterone, fatigue, and muscle loss. HRT is prescribed and monitored by a healthcare provider to ensure the right dosage and balance of hormones for each individual's needs.
