I find the marketisation of menopause very interesting, but from a different angle. A year or so ago I started looking into my options. Boots had a leaflet about menopause. It was full of suggestions of supplements and skincare products I could buy. Didn't mention HRT. Holland & Barrett have plenty of things to sell for menopause, from supplements & skincare to foods. My Facebook feed has plenty of adverts for mindfulness for menopause, natural menopause, workshops, supplements, cooling clothing, special bedclothes, etc.. I've been given books about natural menopause full of ideas for things you can buy which might ease some symptoms. Many of these "natural menopause" sources disparage "big pharma", which wants to, shockingly, sell me drugs.
I had a consultation with a private menopause specialist at Newson Health, while waiting for my NHS menopause clinic appointment. They both recommended the exact same thing, which was estrogen gel plus Mirena IUD. The estrogen gel cost about the same on private prescription or NHS prescription charge, about £10 a month - a fraction of what I could easily spend on "natural menopause" products. I think I read that most commonly used HRT products make very little money for the manufacturers.
So yes, menopause is being marketised, but the demand for HRT seems to be mostly led by women asking for it. In contrast, what is marketed to us via advertising are alternatives to HRT.
