Re: Does Synthroid effect menstrual cycle?
I believe that most doctors do not GET the correlation between thyroid and menstruation. WOW, what a bummer!
My story: (long story short - I'll try). Went to PCP in Feb - Had trouble swallowing and massive periods (long and heavy at 43 for 1 year). They did US on thy and pelvis. Pelvis - fine! Thy - Nodule. Blood - hypo/hashi's. OK, let's deal with the thyroid first.
Did a lot of research, come to find out, periods ARE affected by thyroid malfunction. (period - double entendre (sp?)).
The PCP nurse calls me back... the doc wants you to come back in and see what is going on with your heavy periods (truly love their attention - but lack of knowledge - to the matter). I said, I think it has to do with my thyroid, so I'm going to deal with that first. She said, "Really?". I said "REALLY!" sweet but short.
In that one month time, I was put on 50 mcg of Levoxyl, 1st month, same heavy, clotty time of month. Since then, nothing... Ahhhh, what a relief, I may actually be on schedule now instead of every 15-21 days..... It's been about 28 days now and still haven't seen a drop - wow! That's how it used to be - about every 31-35 days(during undiagnosed hypo/hashi's - 20 days heavy, intense monthlys) - 4 day periods - never have/had any cramping.
There is no doubt in MY mind that an underproductive thyroid will effect your periods (heavy, frequent) and then after meds are started and your body changes (depending on weight/script/body) the changes will start. I'm just starting to see it, but it DOES happen!
I guess, my take on it is the body is actually starting to function somewhat normally again, so give it some time to come back to reality! You know what is or somewhat should be normal for your body, listen to it, trust it, and tell your doc... not immediately, give it some time, and after that, hey.....
Still learning and will continue to educate with power of knowledge... We all want to see our grandkids grow up!
