Here are some things I found on hypothyroidism.

Hypothyroidism is a very common condition. It is estimated that 3 to 5% of the population has some form of hypothyroidism. The condition is more common in women than in men, and its incidence increases with age.

Below is a list of some of the common causes of hypothyroidism in adults followed by a discussion of these conditions.

Hashimoto's Thyroiditis
Lymphocytic Thyroiditis After Hyperthyroidism
Thyroid Destruction (from radioactive iodine or surgery)
Pituitary or Hypothalamic Disease
Medications
Severe Iodine Deficiency

Depending on the lab used, the absolute values may vary, but in general, a normal TSH range is between 0.5 to 5.0uIU/ml. Evergreen Hospticals labs tested my TSH levels at 0.816. Normal for them is 0.35 - 5.50. My doctor circled this and we are going to discuss this further on Aug. 29th when I go back in for my next Depo shot. It will be interesting to see what she wants to test next.

Physical: Signs found in hypothyroidism are usually very subtle and are not frequently observed unless the physician is searching for them. Many signs are dismissed as part of aging; however, it is important to consider a diagnosis of hypothyroidism when they are found.

The differential diagnosis for hypothyroidism is quite large because of the nonspecific nature of the more frequent presenting complaints (eg, physical tiredness, impaired cognitive function, dry hair). The search for additional symptoms and signs supports a more specific diagnosis. The classic symptoms and signs of cold intolerance, puffiness, decreased sweating, and coarse skin previously reported in 90-97% of affected adult patients may only occur in 50-64% of younger patients.

Each individual patient will have any number of these symptoms which will vary with the severity of the thyroid hormone deficiency and the length of time the body has been deprived of the proper amount of hormone. Some patients will have one of these symptoms as their main complaint, while another will not have that problem at all and will be suffering from a different symptom. Most will have a combination of a number of these symptoms. Occasionally, some patients with hypothyroidism have no symptoms at all, or they are just so subtle that they go unnoticed. Note: Although this may sound obvious, if you have these symptoms, you need to discuss them with your doctor and probably seek the skills of an endocrinologist. If you have already been diagnosed and treated for hypothyroidism and you continue to have any or all of these symptoms, you need to discuss it with your physician. Although treatment of hypothyroidism can be quite easy in some individuals, others will have a difficult time finding the right type and amount of replacement thyroid hormone.
Because the body is expecting a certain amount of thyroid hormone the pituitary will make additional thyroid-stimulating-hormone (TSH) in an attempt to entice the thyroid to produce more hormone. This constant bombardment with high levels of TSH may cause the thyroid gland to become enlarged and form a goiter (termed a "compensatory goiter"). Our goiter page goes into this topic in detail, and outlines that a deficiency of thyroid hormone is a common cause of goiter formation. Left untreated, the symptoms of hypothyroidism will usually progress. Rarely, complications can result in severe life-threatening depression, heart failure or coma.
