Today, in the United States and around the world, iodine deficiency is a growing problem. In 1970, only 2.6% of the US population was iodine deficient. By 2005, that number had jumped to 16.5%..

where is your proof that hyperthyroidism is due to iodine? IN WHAT there is too much iodine?
In large quantities, iodine can reduce the release of thyroid hormones from the thyroid gland. If the hormones are not released, their effects won't be seen. Occasionally, doctors use this mechanism to control very active thyroid glands that produce too much thyroid hormone. This type of therapy is difficult and is not used as commonly today. An excess of iodine also decreases the blood flow and growth of the thyroid gland, which is characteristic of Graves' disease. As a result, iodine may be used to reduce the thyroid hormone level in conjunction with surgery to remove some or all of the thyroid gland tissue and assure a good outcome.
While I've just explained how too much iodine exposure can actually shut down thyroid hormone production, in other situations, an excess of iodine may actually cause an over-production of thyroid hormone and hyperthyroidism.
If a person has been exposed to relatively little iodine and then consumes a diet rich in iodine, the individual can develop an excess production of thyroid hormone (iodine-induced hyperthyroidism). In general, this occurs in people who have an underlying thyroid disorder that has not yet manifested clinically. Iodine-induced hyperthyroidism is important in areas of the world where iodine intake is high. We actually see this quite commonly in the United States among populations who have emigrated from countries such as Iran and Africa. The name for this response is the " Jodbasedow" effect, which actually occurs only in a small fraction of people at risk. Even though it is relatively uncommon, it is important since administering iodine-containing dyes for medical procedures (such as CT scans, barium procedures, etc.) can trigger this effect.

You could ask a doctor for ways to test, or to run tests for you, but it won't be easy to find one that doesn't believe 150microgramm is way to little.
Geez my doctor was shocked when i told her, because she thought that amount would be deadly, but nope, im still alive :p.
What if you're not getting the mineral Iodine from rich foods?
A deficiency of iodine will lead to goitre; this is the condition tends to appear during puberty or pregnancy. People with goitre become lethargic and sensitive to cold; they tend to gain weight and their skin becomes coarse. When there are inadequate thyroxine levels, a condition called hypothyroidism occurs. Symptoms here are puffiness around the eyes, sparse and course hair, course and dry skin and memory impairment.
Who Needs Iodine?
Everyone needs iodine to produce thyroxine, but the signs of deficiency are easy to spot and treatment can be given. Those more at risk are women at puberty, pregnant women and children. There has been a suggestion that women in low iodine areas, are more prone to womb cancer. Some foods contain excessive levels of the minerals manganese and cobalt which interfere with the thyroid gland, extracting iodine. If you are in the habit of eating large amounts of raw cabbage you must ensure you are also getting sufficient iodine.
Some dieters believe that they struggle with their body weight because of an under active thyroid gland, this is possible, however, in most cases it has been found that they were simply ingesting too many calories and not active enough!
