I am a 40 yr old female and just underwent hemithryoidectomy (removal of left lobe) on Oct. 21/09. Previous to surgery my tsh, t3 and t4 were always normal and bloodwork was negative for Grave's/Hashi's. I had 3-4 nodules being 2-3 cm each in size. Because of the size and discomfort it was decided to remove the left lobe. The day after surgery the surgeon put me on 0.125 mg of Synthroid. I have been taking this dose once a day for just over 2 weeks. I have recently started feeling cold, lightheaded/dizzy and sometimes a little shaky. Could this be from too much or too little dose of Synthroid? I think these are symptoms of hypothyroid so would that mean I need a higher dose of Synthroid? I went to my GP today and she ordered some bloodwork for tsh and (free?) T4. So hopefully I will have some answers early next week... if I can take it until then.
Thanks for any insight.
I should also say that the biopsy came back showing no malignancy but has been sent somewhere else for a second opinion. I think this is making me a little nervous as well.
Your symptoms could be either hypo or hyper. My bet would be that you're either a little hyper or your levels are just fine but you can't tolerate that does of Synthroid. I need to be on 75mg of synthroid to feel good but it took 5 months to get there. Every little increase gave me hyper symptoms just like yours. Scary as heck and totally interfered with my life. Baby steps finally got me to where I need to be. See what your tests come back as. If they are normal you may just need to lower your synthroid dose and work your way back up.
I had a total thyroidectomy. I had a very large multinodule goiter that decided to act up for about 6 months. Thyroiditis I think my Dr called it. I wasn't on meds before the surgery. No cancer which was good. Anyway, I had to start the synthroid right after surgery. My endo gave me 88mg based on my weight (I was terribly thin at the time). Right away I started to get shaky and lightheaded; had heart palpitations. My levels weren't off but I just couldn't take that much synthroid. Dosed down to 50mg and went hypo; up to 75mg; up to 100mg and it started all over again. Levels were "normal" but I couldn't function. I'm now back on 75mg and everything has evened out. I just couldn't ramp up quickly. Hopefully your blood work will give you some answers.
