hello skavitha, I concur with goolarra. In addition, I have found over the years that taking daily meds and feeling good is much preferred over brain fog, moodiness and joint pain. Finding the right dose is a individual process, but doable! I would also suggest keeping a daily log of symptoms (including, temp, BP and heart rate) so you will know (and remember) what is working.
Your numbers aren't awful. FT4 is 39% of range, which is low of the 50% target. FT3 is 36% of range, and the target for FT3 is 50+%. So, both are low and could definitely explain your symptoms. TSH is high, to, so your pituitary wants your FT3 and FT4 to be higher as well.
If I were you, I'd start taking the meds. However, be aware that the initial dose we are on is seldom where we end up. After 4-6 weeks, you'll have to retest and re-evaluate symptoms and see if you need to increase. 25 mcg is a fairly conservative starting dose, which is good. It's best to start out low and increase as needed and tolerated.
Starting meds doesn't necessarily mean you will be on them for life. However, Hashimoto's thyroiditis, an autoimmune disease, is the most prevalent cause of hypo. If you have Hashi's, you will be on meds for life (whether you start taking them right now or not). If you want to know if you have Hashi's, ask your doctor to test for the two antibody markers for it, TPOab (thyroid peroxidase antibodies) and TGab (thyroglobulin antibodies). It's a simple blood test.
The doctor prescribed 25 mcg of Thyronorm. Should I go ahead and start taking it or is it better to wait and watch? I am worried that I will have to start taking the medicine life-long. Please advice. Thanks.
There are great folks here who can help you out. I am new but for what it is worth my TSH was 4 and my free T's were similar range and just a little lower than yours. I am hypothyroid. I had a lot of odd symptoms and many I didn't connect and now realize were hypo issues, not aging issues (they went away with treatment which amazed me). Lastly, find a good doc and or second..third opinions if you don't get a good feel from your doc. I saw a lot of docs who missed it completely.
Good luck, Kel
