Menopause guides: symptoms, HRT, sleep and everyday changes
Ines Kovac writes the practical guides on Menopause Plainly: perimenopause, symptoms, hormone therapy, sleep, hot flushes and weight. She builds each piece from NHS and NICE pages, The Menopause Society's position statements and the studies behind them, and links every claim a reader might want to check. She says plainly what the evidence supports and where it runs out, and she never tells a reader to start or stop a medicine. Any correction is noted on the page where the error occurred.
