Hello, my GP has agreed to increase my levothyroxine back to 150mcg from 125mcg. I am so happy as I have had lots of hypo symptoms ( total thyroidectomy 35 years ago) since he reduced it a year ago. I think he was a bit reluctant but I know that's where I need to be.
I am having a blood test in 6 weeks and will follow the advice on this forum and take levothyroxine 24 hours before blood test and fast for 12 hours. If the blood test is drawn a little over 24 hours is that ok as it's difficult to know how long I will have to wait in clinic as depends on how many people want a test that day as to how long you wait. Also why is it necessary to fast before hand? What results would fasting alter?
One last question, I started taking the extra levothyroxine today but wondered how long before I should start feeling an improvement in my symptoms which are mainly aching legs, dizziness, lack of motivation, memory loss, insomnia and constipation?
Thank you in advance.
