Hello Jean, Happy Sunday.
Our thyroid gland has lobes and makes 2 very important horomones. T3 is called Triiodothyronine (say that 5 times quick, LOL), and T4 is Thyroxine. The gland takes T4 and makes it turn into T3. In some people the nodules ruin the gland and cause pain, so they take it out.
I have had Hashimoto's since I was 27. However, I had many symptoms when I was 12. I had constipation, tiredness, and feeling cold. Back in the 1970's my GP back then, never tested me. They did not know enough to do so. I complained of being cold. I lived on laxatives since I could go 4 days without a bowel movement. i was only 12. Nobody thought this was weird???
I grew up without a Mother and my Father was not medical and had no idea what was wrong with me. Since I was young, they just thought it was a temporary problem. I also caught Epstein-Barr virus back then called MONO. I went years without knowing I was ill. When I went to college my professor in Nursing school, noticed a goiter. She said I had one!!! She was spot on, but who knew back then. I was not getting my period, and the other symptoms were still with me. If I did get my period it was heavy.
Later on, I got a wonderful GP,(who I am still with), and he immediately called the lab and ordered TSH, T 3 & T 4 and other blood work. I was started on T4 - Levothyroxine brand is synthroid. However it did not work on me!!!
My doctor changed the med after a period of time and that one was T4 called Thyrolar, also did not make my level come up!!! i was so shocked as I took it everyday. Jean I so sick from it, I had headaches and muscle pain, and loose bowels and it was almost like having "food poisoning" with cramps etc.... my dose was only .0.25mcg. I never got up to 100 mcg.
It was later discoverd that Hashimoto's had destroyed my thyroid gland and rendered it useless. I aslo have nodules, so I can't take LEVO as my body will not convert the T4 into T3.
TSH is (Thyroid Stimulating Horomone) and it measures both T3 & T4 in your blood AS AN OVERALL NUMBER. Most people need T3 & T4 levels measured to see if they are doing their job.
The words in your case are: sub-clinical mean not enough symptoms so what they said was not enough to be hyperthyroidism. I think it is a fancy way of saying you have Hypothyroidism. you may have Hashimoto's and that is why I try and help, as I do not want YOU to suffer like I did.
Believe me, I would not wish this on anyone!!! It is a real pain! However we live in modern times and have wonderful meds to help. We must make Lemonade from Lemons! We need to support each other and help one another regardless of whatever country we live in. So many of us have it. Back when I was young, I knew nobody who had it.
I hope I can help you. i feel so much empathy for people who have this.
