I'll give you my point of view based on what I have seen.
I would say there are three main reasons. The first has to do with how the medical field works. When people make recommendations, they're working in a very isolated way.
Many women's health issues have been grouped together in gynecology and obstetrics, which was entirely justified because it was thought that female hormones were linked solely to reproduction. That means that recommendations will be made mostly, but not exclusively, by obstetricians and gynecologists. They're excellent. That isn't the problem. They're essential, and they need to be part of the discussion, if you will.
However, there isn't the view that knowledge needs to be integrated. The problem is the integration of knowledge. It needs to be integrated, because a lot of researchers have looked at female hormones: cardiologists, neurologists, psychiatrists, family doctors and urologists.
Of course, there's room for research to improve hormone therapy care. However, I also think that the work should take into account what's being done on the front lines. When someone has an issue, such as shoulder tendinitis, that's related to premenopause, perimenopause or menopause, they go to see their family doctor. However, the doctor won't know whether it's related to a hormonal issue. If they have osteoporosis or depression, who are they going to see? Their family doctor.
There needs to be expertise in front line medicine, because doctors are the ones who see women, by and large. They also need to join forces with all the professionals. Having done so, I can tell you that we have much less need for specialist medical consultations. The specialists love that, because they have clear-cut issues in front of them, not issues due to hormones. When the issue is due to hormones, they don't really know.
I'll give you one example, but I could give you several.
Premenopausal patients often have heart palpitations. Doctors don't know if that's due to a lack of progesterone. They don't know. They don't learn that. The patient isn't sent to gynecology; they're sent to cardiology. The cardiologist does a thorough examination but concludes that those are benign palpitations. They aren't really sure what to make of that.
That's how it is for a lot of women with health problems who reach premenopause, when their cycles are still regular. I think that's the crux of the issue. In any case, that's what I saw. It jumped out at me. It's easy and straightforward.
