I'v recently been diagnosed with hashimotos. My practitioner has been treating me for kidney yang deficiency and spleen deficincy (borderline underactive thyroid in western medicine) and iv been taking a custom made Chinese herbal formula for several months now. I have not yet told my practitioner about my diagnosis as it was so recent. Also, my doctor has recommended I start taking levothyroxine, although I'm borderline and do not yet have an underactive thyroid nor do I have any symptoms (apart from irregular menstral cycle). She recommended this as I am trying to concieve and suffered a miscarraige last year. She advised that levothyroxine would reduce the chance of complications with the pregnancy. I really would prefer not to take the levothyroxine and go down the natural route but fear another miscarraige. Any advise would be greatly appreciated.
