Common Questions and Answers about Synthroid and fasting
synthroid
With a synthroid dosage of .150 my TSH was normal but I was experiencing chronic headaches, irregular periods and pre-menstrual type symptoms regularly. My doctor adjusted my meds to have me take .200 twice a week and stay at .150 the rest of the week. I feel MUCH better. However, now my TSH is at .05 and my FT4 is at 2.43. My T3 and T4 remain in the normal range though. I'm not sure what to do as I feel so much better, yet my TSH is extremely low.
Hello Doctor, I was diagnosed with thyroiditis last year at age 57, but I'm not sure what kind. I started out hyper which my doctor treated with beta blockers to slow my heart rate. Then I went hypo, and I've been on 50 mcg of Synthroid for the past year. My last TSH was 2.98. My question is regarding blood glucose. My last fasting test was 127. I've always tested under 100. I'm fearful of developing diabetes. Is the synthroid causing my blood sugar to rise?
Synthroid needs to be taken first thing in the morning, with a cup of water, 30-60 minutes before eating/drinking anything else. I take my thyroid medications first thing when I get up, then get ready for the day and by the time that's done, at least 30 minutes has gone by and I can go ahead and take the rest of my meds, have coffee and either eat breakfast, if I'm going to or leave for my morning walk.
I have had H.T. for two years now. I take a synthroid supplement every morning. I have had one 'strange episore of eosphagitis (lasting for a cople of months) and now find my fasting blood sugars are climbing. I have stiffness in my knees when I go down stairs and the big thing, recently is I now have eustatian tube dysfunction. Have some very painful episodes while waterskiing this past month.. Now feel stuffy and full in ears and I am afraid to fly to see my Aunt next month..
Thank you for responding, Red Star. I'm sorry, I meant not taking the thyroid med prior to labs. My husband used the word fasting and it stuck in my head. In reality that's what I'm doing since I don't want to eat prior than wait 2-3 hrs to take my med than wait another hour to eat, so I'd rather fast...no food or med till after my labs. Would this rule still apply if you're on a T4 med?
Within about six months of being on Synthroid and without changing my diet or exercise, I began to put on weight. I gained about 15-20 pounds in six or so months. While I was mentioning this to my endocrinologist, he kept saying it wasn't the medication. I had fasting glucose, glucose tolerance, cortisol, etc., testing but all is normal. My weight gain now is about five pounds a year---doesn't sound like much but now that I'm 43, it really is.
Do you guys have any explanation for the weight loss
I continued to have blood tests fasting and non fasting and the prolactin levels were still high. I was referred to a Endocrinologist and she found a nodule on my thyroid and now I am getting a ultra-sound on my thyroid. I often wake up with nigh sweats and feel tired but I always though from working odd hours and my job. Any advice would help.. I feel like i am getting to the point of not knowing whats wrong or if triple the amount of prolactin in males is dangerous..
thanks .
Still trying to get tsh normal after months of dosing changes on synthroid. After starting synthroid my fasting glucose has been in the 90s so dr. says the other high readings must have been a fluke.
I obtained all my lab reports over the past several months and did some research online to discover 90s for fasting glucose is not very good. I'm 25, very fit, low body fat, etc - my fasting blood sugar should be in the 70s or 80s.
My T3 was 110 and T4 Free was 1.3. I checked on TPOB results and it was "very high" and they want to send me to an endo. They did increase the Synthroid to 112. I want to give it a chance to work before I run to someone else. I don't think five weeks on 88 is enough take me from zero during fasting month to a normal zone. My main symptom is FATIGUE. Am I safe to wait? Thanks so much for responding.
The fertility clinic is also testing me for everything as we and everything is testing well except that on my 3 days after my period bloodwork they did a non fasting tsh and prolactin level test which came out very elevated. My TSH was 5.7 and I don't know the prolactin number but it was high too. They sent me for a fasting thyroid function test and prolactin level test which I did 4 days later and all of the levels were normal. My TSH was at 3.
