1)Should I really be taking more thyroid medication purely for the purpose of weight loss? Definitely not! Your TSH looks 'good', but the actual hormones your body uses need to be checked - called Free T3 and Free T4 testing. TSH is a messenger hormone - not a body 'consumable'.
2) If I end up taking too much to treat my thyroid, what side effects should I expect? Feeling hot, shaky, sweaty, insomnia, high heart rate, possible heart palps, fast and inadequate digestion, sore muscles, theres more........
If your doc is basing the higher dose on weight alone, I'm very surprised. Has he looked at the free T3 and T4 hormones? Proper diet and exercise (as you seem to know) is the key to weight loss, not more hormone.
Thanks for your response. I felt like I was going crazy! No, the T3 and T4 were not looked at with my last blood test, only the first (if I remember correctly--I had a lot tested at once). I did not have a test immediately before this appointment.
I have a full month's worth of 50 mcg pills left... I think I will ask the pharmacist tonight what I can do about not taking the higher dosage, if it is available for me to pick up. Maybe I should look for another doctor...
I think you need to find an endocrinologist. I was treated by my family doctor for my hypothyroidism for 14 years. I had regular bloodwork every 6 months and my tsh never changed from 4.0 and I felt fine. For 14 years. Then one day my tsh came back at 5.5, doc increased my meds without doing any kind of exam or any further bloodwork other than tsh. I had a gut feeling something wasn't right so I went to an endocrinologist, he found a nodule and it turned out to be cancer. Not that you have cancer, I just think when you are dealing with thyroid issues you need someone who specializes because half the docs out there do not know what the are talking about.
I think you should strongly consider finding a new doctor. I have been losing weight and as a result my dosages of Levo have gotten too strong and had to be lowered. I have now lost 44 pounds. The times that my medication was too strong and I became Hyper instead of Hypo were absolute misery! Hot flushing feelings, rapid heart rate, extremely high BP, anxiety and nervousness, depression, hair loss, etc. The first time it happened I didn't know what was wrong until someone here on the forum told me. I then called my doc and she lowered my Levo from 100 mcg. to 50 mcg. Then a few months and a few more pounds lost later, it happened again. Now I am taking 25 mcg. of Levo. I can't believe your doctor raised your dosage to make you lose weight. Sounds very scary to me.
Thank you to everyone for the replies. I think I will start looking for an endocrinologist as was suggested. I felt a little silly considering that at first because I am perfectly healthy aside from my now-minimal thyroid problems and the occasional migraine, but I think it may be time. My mother is also having problems with her dosage (she is taking the same as I am, but still experiencing hypothyroid symptoms) so maybe we can go together.
I feel a bit bad for my doctor as I have been going there since birth, 24 years now, and the nurses are so lovely and nice... but this is my health we are talking about, so I really can't joke around. He is an older gentleman and I've heard several of my family members sadly admit that his medical knowledge is becoming outdated. With any luck there is someone local who can help me safely reduce my weight without increasing my dosage. :)
I totally agree that thyroid hormones should not be used for weight loss. You do need to get your Free T3 and Free T4 tested as LazyMoose suggested.
It's fine if you want to find an endo, keep in mind that most endo's (and/or insurance companies) will require a referral from your pcp. In addition to that, it's not absolutely critical that you have an endo to treat you; you can use any type of doctor, so long as they knowledgeable with thyroid issues and are willing to look at the FT's and dose so as to alleviate symptoms.
