So signs of androgen excess.
New hair or you never had it before.
Okay.
scalp thinning specifically at the temples or at the crown, irregular cycles, et cetera, that's when we need to start checking your testosterone levels and something called SHBG.
SHBG, you'll hear a lot about, and I did a great podcast with Dr. Jim Simon.
He really did a deep dive into SHBG, is steroid hormone binding globulin.
Okay, so you know we talked about ferritin is like the protein that hangs on to iron.
SHBG is a protein that hangs on to estrogen, progesterone, and testosterone.
It is sex hormone binding globulin.
It binds those hormones and renders them inactive until the hormone falls off and then it can like be free and go be active in the tissue.
So the higher our levels of SHBG are, the lower the activity of our sex hormones like estrogen and testosterone.
When we have a low SHBG, we may have higher activity of our testosterone, of our DHT.
Our SHBG goes up when our estrogen levels are up.
So especially with oral estrogen.
So if you are on a birth control pill for treatment of heavy periods or for contraception,
you will have higher SHBG typically than you would have had without it.
That is going to bind the activity of your androgen hormones, okay?
If you have low SHBG, as we see in menopause, you will have higher activity and more free, more of that testosterone that you have circulating will be free and active.
What do you want to bring to this appointment when you go?
I would take photos.
