If you came to me for help with irregular periods, I would think very carefully about your thyroid.
It wouldn’t matter if you already had another diagnosis such as PCOS or hypothalamic amenorrhea. It wouldn’t matter if your doctor had vaguely said at some point that your blood test was normal. I would still think about thyroid. Why? Because underactive thyroid (hypothyroidism) is a common reason for irregular periods.
A change is coming for endometriosis treatment. Until now, the clinical approach has been surgery followed by hormonal suppression with hormonal birth control or other drugs. Going forward, the approach will shift to anti-inflammatory and immune-modulating treatments. That’s because there is growing evidence that endometriosis is not primarily a hormonal condition. It is autoimmune.
Thyroid-stimulating hormone (TSH) was supposed to be a simple way to detect thyroid disease. Before its invention in the 1970s, doctors diagnosed thyroid disease by symptoms.
