Key Takeaways
Hot flashes occur because of changes in estrogen levels
Dr. Green explained that hot flashes and night sweats are triggered by fluctuating estrogen levels as ovarian function declines with age. Vasomotor symptoms are often quick to improve once HRT restores estrogen levels to a steady baseline.
Symptom relief follows a timeline, not an overnight switch
Dr. Green noted that while hot flashes and night sweats often improve within the first few weeks of treatment, it can take three to six months to experience noticeable improvements in hair density, skin elasticity, and fat accumulation.
Early side effects like breast tenderness and mild acne are usually temporary
Dr. Green explained that mild side effects like breast tenderness, acne, and bloating tend to appear early on as hormone levels rise. These initial side effects typically resolve within a few weeks once hormone levels reach a steady state in the blood.
Water retention isn't the same as visceral fat gain
Contrary to widespread misconceptions, Dr. Green emphasized that HRT is generally weight-neutral or even helpful for weight loss long-term. Any early signs of weight gain around the midsection are typically a reflection of temporary water retention in response to treatment, not actual visceral fat gain.
Severe DHEA side effects often stem from unsupervised, high-dose use
Dr. Green explained that online stories about severe DHEA side effects, like excessive hair growth or voice deepening, usually involve people self-dosing far above the 25–50 mg standard clinical range. Side effects at doses that are physiologically appropriate for women are rare. If they do occur, they are typically mild and completely reversible with a dose adjustment.
