I have read all sorts of different personal stories about what happens to hormones after adopting low carb.
For me, PMT became less, um, aggravating.
Some people find it affects their thyroid. Most that i have seen have found thyroid issues improve, a few find the opposite.
Inflammation often subsides...
I am trying to use very non-definite terms, because everyone's experience is different, but i think it is probably safe to say that your hormonal situation will shift somewhat, before settling down to a new, slightly different state.
For me, that was an improvement. Hopefully, it will be the same for you...
