good question…I’ve actually been wondering the same thing because you can look up online which category you fit into best as far as the “different types” but some people say there are 4 main types? And I think others say there are up to 7 different types? My doctor right now is still trying to determine which category I fall into best since I am not overweight and I don’t show any evidence of insulin resistance but my testosterone is slightly high (yet still within a “normal range”) but my ultrasound showed chains of cysts on my ovaries, I have irregular menses, and an FSH/LH ratio indicative of PCOS. I also experience severe symptoms of pelvic pain, GI upset, night sweats, anxiety, depression, and fatigue. But my doctor said she has to run a more thorough urinalysis of all my sex hormones (DUTCH test) and their metabolites to figure out which category of lean PCOS I fit into best (ex: inflammatory pcos maybe? or something else). But even though my testosterone is considered slightly high it’s still within normal range and so is my DHEA and DHEA-S. So now I’m trying to figure out which metabolite in my body is the one converting to excess androgens and causing the symptoms of elevated androgens (hirsutism, irregular periods, etc.) which is much more complicated..I believe if you have insulin sensitivity it is actually a lot easier to figure out/designate which category you fit into (since insulin resistance is often linked directly to increased androgen production)…but if you’re not insulin resistant it can be a lot trickier. Your doctor would probably be your best bet in figuring it out (if you have a good doctor that’s willing to investigate if you don’t fit the “typical criteria”)
Sorry for the super long answer!! I was prob babbling a bit..hoping I said something helpful in there lol…best of luck to you! :)
