Starting HRT after age 65 has a less favourable risk-benefit ratio unless severe symptoms persist.<\/p>\n<h3 class=\"wp-block-heading\">Do I need a progestin if I have a uterus?<\/h3>\n<p>Yes \u2014 always. Unopposed estrogen raises endometrial cancer risk 8\u201315\u00d7. Take estrogen with micronized progesterone (endogest, gestheal, etc.), dydrogesterone, medroxyprogesterone, or a Mirena IUD.<\/p>\n<h3 class=\"wp-block-heading\">How long can I stay on HRT?<\/h3>\n<p>Modern practice: lowest effective dose, shortest duration \u2014 typically 3\u20135 years, reviewed annually. Extended use is appropriate for severe symptoms, premature menopause, or osteoporosis; discussed on an individual basis.<\/p>\n<h3 class=\"wp-block-heading\">Is HRT safer as a patch or gel than a pill?<\/h3>\n<p>Transdermal estrogen has a lower VTE risk (no first-pass hepatic effect) and is preferred for women with VTE risk factors, migraine, or hepatic concerns. Oral is convenient and well-studied but carries slightly higher thrombotic risk.<\/p>\n<h3 class=\"wp-block-heading\">What about bioidentical hormones?<\/h3>\n<p>Estradiol (the molecule in Progynova) is bioidentical. Conjugated estrogens (Premarin) are not strictly bioidentical. Micronized progesterone is bioidentical. &#8220;Compounded bioidentical&#8221; custom-mixed products at non-standard doses have no proven advantage and often lack quality control \u2014 most gynaecology societies do not recommend them.<\/p>\n<h3 class=\"wp-block-heading\">Will HRT cause breast cancer?<\/h3>\n<p>Risk depends on type and duration. Estrogen-only (women without uterus): no clear breast cancer risk increase over ~7 years in WHI. Combined estrogen-progestin: ~+8 cases per 10,000 women per year. Risk returns to baseline within 2\u20135 years of stopping.<\/p>\n<h3 class=\"wp-block-heading\">Will HRT help my mood or sleep?<\/h3>\n<p>Often \u2014 especially if vasomotor symptoms are disrupting sleep or causing irritability. HRT is not an antidepressant; severe mood symptoms may need separate treatment.<\/p>\n<h3 class=\"wp-block-heading\">Can HRT cause weight gain?<\/h3>\n<p>Weight gain is more commonly linked to the perimenopausal transition itself (shifting body composition, declining estrogen) than HRT. Modern low-dose HRT is typically weight-neutral.<\/p>\n<h3 class=\"wp-block-heading\">What should I do if I have vaginal bleeding on HRT?<\/h3>\n<p>Expected for 3\u20136 months on continuous-combined HRT. Withdrawal bleeding is expected on cyclic HRT. <strong>Unexpected or prolonged bleeding<\/strong> beyond 6 months needs clinical review (endometrial biopsy or ultrasound) to rule out endometrial hyperplasia or cancer.<\/p>\n<h3 class=\"wp-block-heading\">What about non-hormonal alternatives?<\/h3>\n<p>For vasomotor symptoms: SSRIs\/SNRIs (paroxetine, venlafaxine), gabapentin, clonidine, cognitive-behavioural therapy, fezolinetant (newer neurokinin-3 antagonist). For genitourinary symptoms: vaginal moisturisers, lubricants, ospemifene.
