L.,
Yep, I was finally diagnosed with Hypothyroidism when my daughter turned 4. It turned out that I developed Hasimotos disease while I was pregnant. Hashi's is an autoimmune disease that attacks the Thyroid and slowly decreases the production of thyroid hormones. It is a silent disease with no symptoms until you develop hypothyroidism. Some of the more obscure indicators of hypothyroidism you did not mention are loss of eyebrow hair at the outer corners, coarsening of the skin, development of nodules in the thyroid, intolerance to cold, and in my case an enlarged thyroid gland (goiter), which began to obstruct my airway.
After nearly a year of blood tests, sonograms, a biopsy, and a referral to an Endocrinologist we decided to remove the thyroid completely. Last June I had a complete thyroidectomy at St. Joseph Hospital. The thyroid was the size of the surgeons fist when she got it out.
This past year we have been working to get my synthroid levels correct. I have to have a my TSH levels checked six-eight weeks after I have been on a medication level. We have adjusted my synthroid 3 times in the last 9 months. Our target is a 1.0 TSH. Currently, I take 150mcg of Synthroid a day. The next appointment with my Endocrinologist is in June.
The good news is that while I'm still learning how to eat and loose weight. My energy levels are much better. I don't feel tired and sluggish all the time and I'm not depressed. Dr. Menon says that Hypothyroidism is the most under diagnosed issue in women. Frequently doctors just tell us to work harder to loose the weight or prescribe antidepressants.
Hope this helps answer you questions.
Best wishes,
J.
PS - Blood test don't always give doctors the whole picture. I tested within normal ranges for TSH the entire time. It was not until the goiter started to show that I could convince my regular doctor something was wrong.
