Well...it's been a rough 2 and a half months. I'm a 30 year old female with hypothyroidism, or so I thought? I was on 112mcg of Synthroid while being pregnant and through my whole pregnancy. After I delivered my baby in July 2016, my levels began to drop. I went from being on the 112mcg to 100mcg in September, then from 100mcg to 88mcg in December. I'm still on 88mcg now, but feel awful. The beginning of March 2017, I started feeling bad. I had chills on and off, then heart palpitations set in. I amhave been to the ER twice over my heart, whether it be from heart palpitations or a racing heart. I've seen cardiologist for echocardiogram and 24 hour monitor and says everything looks good, I'm just experiencing some PVC's (irregular heartbeats). Well...as it's now May of 2017, I'm still having these issues. I've lost 10-12 lbs within the 2 month period, I've had anxiety/panic attacks, some say they think I've experienced post-partum depression (as when this all started my son was only 7 months), I've had to quit breastfeeding because of taking medications, and was put on Zoloft for the anxiety and panic attacks, and I have a bacterial vaginitis as well and taking antibiotics for that (TMI). Anyways...ER doctors checked thyroid level and said "it's normal", but I beg to differ. I'm still feeling bad with heart palpitations and fast heart rate being my main concern. Has anyone experienced anything like this? I'm worried I'm hyperthyroidism, when I've been hypothyroidism for about 10 years now. I also had radioactive iodine to kill out my thyroid 10 years ago, too. I need answers...

    Hi, I don't quite understand what you mean by my levels began to drop. It sounds like your thyroxine levels were too high and your endocrinologist decided to reduce your daily dose of Synthroid. It's best to talk to your endocrinologist. I could be that your Synthroid dose is still too high. 

    Were you diagnosed with Graves' disease before the treatment with radioactive iodine? There have been cases where patients had a relapse of Graves' disease after treatment with radioactive iodine. This can happen even after decades of hypothyroidism requiring daily thyroxine supplements like Synthroid.

      Hi. Thank you for your reply. When I said my levels began to drop, I was applying it to mean that my dr. redused my medication (lowered it.) I did not have Graves' disease before. Thanks.

      I had the RAI because I was hyper at first, so they gave me RAI and that made my hypo. My report from my scan on my thyroid states...no thyroid activity.

      I went to my thyroid specialist day before yesterday and demanded answers! They did bloodwork and sure enough, I'm hyperthyroidism. Wow...my body has been on a roller coaster for the past 2 and 1/2 months. He reduced my Synthroid from 88mcg to 75mcg with also saying to not take any Synthroid for 3 days, then start on the 75mcg. So hopefully I will start feeling better soon!
