Based on your test results, you have HYPERthyroidism. Your thyroid is producing too much thyroid hormone. Symptoms of hyperthyroidism include eyes looking like they are popping out of your head, fast hear rate, palpitations, shortness of breath and weight loss. This happens sometimes in pregnancy. It is often transient, meaning it goes away after pregnancy. However, it needs to be treated and monitored throughout your pregnancy. As long as you get it treated in a timely manner, it shouldn t affect the baby. The biggest risk to your baby is if you don t get it treated- baby s system won t make thyroid hormone correctly and could become HYPOthyroid after birth. There are many potential causes of hyperthyroidism, most of them benign. You could have an autoimmune disease, or there could be a mass there causing the elevated hormone levels. Either way, please see an endocrinologist for evaluation. You will likely need a thyroid ultrasound and you will definitely need medication to control your thyroid and frequent monitoring to make sure your hormone levels are appropriate. Good luck!
