Changing the name of PCOS to PMOS won't really matter when doctors don't keep themselves updated.
Women's health is grossly understudied. That's why doctors, especially gynecologists who are directly involved in women's health, should be more proactive in staying up to date on new developments. But sadly, this is not the case.
I was 12 when my periods started becoming irregular. I went to three different doctors. All women, all experienced.
The first doctor was my regular. I went to her three times. Each time, she would tell me to lose weight and send me back with birth control. One time, she told me to wait during the consultation so that she could go check the cooker on the stove.
The second was no different. She just changed her birth control to a different one
Now the third one. She actively participated in and attended medical conferences, did research, and published papers. Back then, we did not consider it an important criterion, but it was the most important one. She took one look at me and gave me a PCOS/pmos diagnosis.
The more I think about it, the more annoyed I get. I was a walking textbook case of PCOS with PCOS belly, overweight, male pattern facial hair, and pigmentation. Yet it took a year and three doctors to get the correct diagnosis. Why? Because the doctors were only doctors part-time, the rest of the time they were homemakers. They did not bother with a blood test or ultrasound, never considered the possibility of pregnancy, heck, they never even asked if there were any clots in my period blood (there were). Their focus was to see maximum patients in the minimum time because they spent the rest of their time managing their house. They did not bother to look deep and took the easy way out.
In the medical field, you must be updated on the latest developments. You cannot half-ass things. Of course, male doctors are dismissive too, but since I haven't seen a male gynecologist, I don't know if they are any better.
