Hypothryoid and irregular periods

[maraj]

I was dx almost a year ago and am currently on 75mmg of Synthroid.  I have always had irregular periods and at the synthroid helped to some degree, but now is causing a lot of minor spotting throughout my my cycle and has not normalized.  Will it ever or could my dosage still be too low even though my doctor says I am now within normal range?

While thyroid dysfunction can alter menstrual periods, if the levels are in range it may not be only the thyroid -- if you have been on a stable dose with numbers in range then check with your GYN for an eval.

Problems with my period resulted in my thyroid diagnosis.

There can definitely be a relationship -- but, there are many factors and many questions to be addressed.

One, is what are your levels?  Different doctors have different treatment goals.

My situation normalized only after I found the doc that treated my TSH down to under 1 (and my goiter, then my "generous" thyroid finally went down to size). Also, are your other numbers at least at mid-point of normal or above?  

Have you had a recent gynecological exam?

I did have to have a D&C to get things "cleared up" as my uterine lining had thickened -- from reading, I think that was because of my hypothyroidism the uterus lining had not properly shed each month, which led to more and more bleeding, then no bleeding.

Actually, taking Levoxyl (like Synthroid) initially caused more bleeding -- then, after D&C and getting dose increases, my bleeding once again normalized after years of nonsense.

Also, in my first few years of thyroid treatment, my doc checked my thyroid blood levels every 2-3 months, to adjust my dose as my thyroid continued to fail from Hashimoto's, or autoimmune, hypothyroidism.

Hope my experiences will help you.  Will look to see if you post your lab's normal range, and your thyroid numbers -- TSH, Free T-4, and Free T-3, and perhaps more of your story.
