This constant bombardment with high levels of TSH may cause the thyroid gland to become enlarged and form a goiter (termed a “compensatory goiter”). Left untreated, the symptoms of hypothyroidism will usually progress. Rarely, complications can result in …
Thyroid stimulating hormone (TSH) is a pituitary gland hormone that stimulates the thyroid gland to produce hormones. When thyroid hormone levels are normal or high, your TSH should be lower.

TSH or thyroid stimulating hormone is a hormone produced in the anterior pituitary gland. This is used to help stimulate the thyroid to produce triiodothyronine (T3) or thyroxine (T4), hormones that help stimulate the metabolism.
In general, thyroid stimulating hormone or(TSH)normally stimulates the formation of triidothyronine (T3)and thyroxine (T4) hormones. High TSH levels can result in a medical condition called as hypothyroidism, which is associated with very little thyroid hormone production by the thyroid gland.
It can be confusing because a high TSH level actually means that there is not ENOUGH thyroid hormone in the blood and this condition is known as hypothyroidism. Hypothyroidism = low thyroid function = sluggish thyroid = low T3 and T4 levels of thyroid hormone in the blood = high TSH (all of these terms are ways to describe the same condition).
For women with low thyroid levels, adequate amounts can be achieved by the use of oral thyroid hormones. For those with high thyroid levels, getting back the normal levels involves treating the associated symptoms, ingesting anti-thyroid drugs, radioactive iodine therapy and thyroidectomy.
A high TSH level can mean a new diagnosis of hypothyroidism or inadequate thyroid replacement. A low TSH might mean hyperthyroidism or overtreatment of hypothyroidism. That said, there are exceptions to these interpretations, as well as what a “normal” level may be for you.
TSH tests may be affected in one way or another if the patient is pregnant, has liver disease, suffers from a systematic illness or uses certain drugs, notes Lab Tests Online. Elevated TSH levels and the resulting hyperthyroidism may lead to ocular problems such as dryness, irritation, puffiness and bulging eyes, notes Lab Tests Online.
