Perimenopause is real and HRT can be transformative. But an $18bn market is growing around claims that often run ahead of the evidence. My @thetimes.com investigation looks at the gaps in research, the potential harms of over-treatment and misdiagnosis and what women are not being told.

Prescription drug ads to consumers are banned in UK & EU. But those rules were written for TV, & newspapers - not Insta, TikTok & YouTube. Social media has enabled importation of US style ads - as we've see with the GLP1s. And don't know the cost. Me for @bmj.com www.bmj.com/content/393/...
