Reportedly there are literally hundreds of symptoms that may be related to being hypothyroid. Following is a link to 26 of the most typical symptoms. Please check and see if you have any of those.
Thyroid hormone is required for metabolism at the cellular level in tissues throughout the body. Inadequate levels of thyroid hormone will cause hypothyroid symptoms that are very undesirable. If left untreated hypothyroidism can cause more serious problems such as cardiac problems, chronic fatigue, and obesity, just to name a few. In extreme cases it can even cause death.
I would be very surprised if you have no hypo symptoms at all, because your limited test results are indicative of being very low in thyroid hormone. Your doctor should be testing the biologically active thyroid hormones, Free T4 and Free T3 instead of the Totals. Also with the high TSH, you should be tested to determine if Hashimoto's Thyroiditis is the cause. With Hashi's the autoimmune system erroneously identifies the thyroid gland as foreign to the body and produces antibodies to attack and eventually destroy the gland. AS this proceeds, the output of natural thyroid hormone is diminished and must be replaced with thyroid medication.
A good thyroid doctor will treat a hypo patient clinically by testing and adjusting Free T4 and Free T3 as needed to relieve hypo symptoms, without being constrained by resultant TSH levels. Symptom relief should be all important, not just test results. Many of our members say thta symptom relief required Free T4 at the middle of its range, and Free T3 in the upper third of its range, or as needed to relieve symptoms.
Hypo patients are frequently too low n the ranges for Vitamin D, B12 and ferritin. You should get those tested and supplement as needed to optimize. Low levels can cause symptoms that mimic hypothyroidism. Low D or low ferritin can adversely affect metabolism of thyroid hormone. D should be about 55-60, B12 in the very upper end of its range, and ferritin should be bout 70 minimum.
The major cause of diagnosed thyroid disorder is Hashimoto's Thyroiditis. From what I have read there is a hereditary aspect with Hashi's.
