Throughout your life, hormone levels go and up down within the body. Different stages of life come with fluctuating hormones, and it is essential to understand what symptoms are normal and which ones require a doctor's appointment. For women, pregnancy, childbirth, and menopause may lead to estrogen spikes and dips, causing symptoms like hot flashes, weight gain, and mood changes. If men experience testosterone dips, they may also experience a reduced sex drive, loss of body hair, and weight gain. Your doctor may prescribe hormone replacement therapy to balance these substances in the body to prevent unpleasant symptoms.
