Question: Here are the facts: I have Hashimoto's, diagnosed when I begged for additional lab testing ( antibody level 782). Md finally stopped telling me I should "start jogging, elliptical workouts weren't enough to improve my stamina XXXXXXX Eight months earlier, went to a cardiologist after noticing an irregular heart beat with mild shortness of breath at randon times ( dinner, movies, work)- nuclear stress test done , echo, 30 day monitor ( 113 recorded episodes) - told left vavle murmer only. Synthroid dose of 137 has shrunk nodules and made my Endocrinologist happy. Current issues - PVC's ( I'm a nurse, saw the monitor strips) have returned in force. Relented to Toprol 25 nightly, not helping much. Recent test - mild changes in right valve despite more exercise and 20 pound weight loss in 2 years. Which is more the problem ?? My Hashimoto's or my heart ?

Thanks for a good description. I need some more information before we can conclusively answer your question.

1. How is your current T3, T4, and TSH level?
2. Is fatigue worsened by activity?
3. Apart from metoprolol (toprol) and synthyroid, what are your other medications?

Please get back to me with details, I shall be able to better guide you

The fatigue is not worsened by activity and my only other medicines are Fish Oil, Vitamin D, and Red Yeast Rice. I do not have a copy of my last labs. I do recall that based on my, either Free T3 or T4, my endocrinologist made a modest change and has me on Synthroid 137 6x a week and 125 1x a week

In that case there doesn't seem to be any concern with your heart.

I would suggest you can continue your thyroid medicines and other supplements and that should settle all issues, may be in the next six to eight weeks.

My mother is 89 and on hospice care for advanced A.D. she has developed, over past year, an indentation on the top of her skull running left to right about three inches back from the front of the scalp. She has several large nodules on her thyroid, but her endocrinologist declined to pursue with needle biopsy or surgery due to her age and advanced disease, A.D. what do you think could be the cause of the changes in the top of her skull, indentation. She also has had significant loss in brain mass in past 12 years per MRI studies ren years apart.

My psychiatrist added 25 mcg of liothyronine, I started taking it Thursday 3-19, to be increased to 50 mcg after one week to augment my depression that has been resistent to other antidepressants. I don t have enough energy to leave the sofa. I also have panic disorder. I have gained about 35 lbs. in about nine months. I m nervous after reading some of the reviews. Should I be. How long can I safely take this medication. Will my thyroid stop producing the harmone naturally if I stay on this medication? When I come off will my thyroid be normal? I have very high hopes that this will increase my metabolism and give me the energy I m lacking and aid in my depression. Thank you
