Hashimoto's Thyroiditis by Ray Sahelian, M.D.

Hashimoto's thyroiditis is the most common cause of thyroid diseases in children and adolescents and it is also the most common cause of acquired hypothyroidism with or without goiter. Autoimmune thyroid disease includes Graves' disease, Hashimoto's thyroiditis, and idiopathic hypothyroidism (atrophic Hashimoto's thyroiditis).

Genetics
The linkage between Hashimoto's thyroiditis and some HLA genes has been reported and a genetic predisposition to thyroid autoimmunity is suggested by observations in twins.

What Causes Hashimoto's thyroiditis?
There is no direct evidence that infections cause Hashimoto's thyroiditis in humans, while iodine and iodine containing drugs can precipitate Hashimoto's thyroiditis in susceptible populations. Like most autoimmune diseases of humans, chronic lymphocytic (Hashimoto's) thyroiditis results from the combination of a genetic predisposition and an environmental trigger. A body of clinical and epidemiologic evidence points to excessive ingestion of iodine as an environmental agent. In genetically determined thyroiditis in animals, iodine enrichment has been shown to increase the incidence and severity of disease.
     Psychological and physiologic stress can induce various immunologic changes. Stress affects the immune system either directly or indirectly through the nervous and endocrine systems. These immune modulations may contribute to the development of autoimmunity as well as the susceptibility to autoimmune disease in genetically predisposed individuals. Stress can be one of the environmental factors for thyroid autoimmunity.

Histology and Anatomy
There is an infiltration of lymphocytes and plasma cells between the follicles followed by their atrophy. Abnormal ultrasound patterns may be present in patients with Hashimoto's thyroiditis disease as diffuse hypoechogenicity and pseudonodules.

Outcome
The clinical course is variable and spontaneous remission may occur in adolescence.

Hashimoto's thyroiditis symptoms and signs
Signs and symptoms of Hashimoto's thyroiditis include goiter, menstrual disorders, short stature, constipation, nervousness, fatigue, and exophthalmos have been reported as the most recurrent clinical features of Hashimoto's thyroiditis. Most patients are euthyroid clinically. Some patients with Hashimoto's Thyroiditis may have no symptoms.

Autoimmune Disorder
Hashimoto thyroiditis is often associated with type 1 diabetes and other autoimmune disorders such as celiac disease, type 2 and type 3 polyglandular autoimmune disorders. Girls with Turner syndrome may develop Hashimoto's thyroiditis. Patients with Hashimoto's thyroiditis have positive antibodies to thyroglobulin and/or to thyroperoxidase in blood. Thyroid function could be normal or abnormal (overt hypothyroidism, subclinical hypothyroidism and hyperthyroidism).

Hashimoto thyroiditis diagnosis
In addition to a complete medical history and medical examination, diagnostic procedures for Hashimoto thyroiditis may include blood tests to detect levels of thyroid hormone and thyroid antibodies.

Hashimoto's thyroiditis Treatment
Specific treatment is currently not available for Hashimoto's thyroiditis. Hashimoto's thyroiditis usually results in hypothyroidism (an underactive thyroid gland), which can be treated with hormone replacement therapy (the administration of thyroid hormone). Hormone replacement therapy usually alleviates the goiter condition.
     L-thyroxine therapy is indicated in Hashimoto's thyroiditis with hypothyroidism, but periodic re-evaluations are required because Hashimoto's thyroiditis could be a self-limited disorder in some cases.

Hashimoto's Thyroiditis questions
Q. Dear Dr. Sahelian. I have read your research and am very impressed by your level of expertise in the area of supplements and your caring and honest approach to this subject. I actually have Hashimotos Autoimmune disease and just recently discovered that the Immune stimulating herbs I was taking was actually hurting me instead of helping me! So I started doing some research and came upon your web site! I did some reading and I decided I really need to consult you regarding what kind of supplements I can take and what I can't! I feel really in the dark because it seems that not many doctors know about Autoimmune disease so unfortunatly they just wing it! I would like to think I'm smarter than that and I want to do everything in my power to help myself heal or at least lead as much of a normal life as possible without the fear of things getting worse every day. So I really would appreciate if you could take some time and do a phone consultation with me. I truly would be greatfull. I have been searching for answers for a long time and if someone can shed some light on this for me, it would mean the world to me.
     A. Unfortunately, at this time, I don't have any knowledge of herbs or supplements helping with Hashimoto's thyroiditis. But if I come across such research, I will mention it on this web site.

Q. I was wondering if Hashimoto's thyroiditis could be caused by the thyroid picking up fluoride, aluminum or chlorine molecules by mistake since they are so similar to iodine molecules therefore causing the immune system to notice a potential invader - the fluoride-aluminum, chlorine molecules and begins to attack the thyroid itself. I was doing some research on the net and saw that when the immune system finds an invader in an organ it sometimes mistakenly attacks that organ in an attempt to eject the invader. I immediately thought of my Hashimoto's. I also checked online for the incidence of Hashimoto in the world and it seems it is always in more "civilized" areas, i.e. areas more prone to use chlorine, fluoride in their water supplies and fluoride in their toothpaste. I also found that fluoride binds with aluminum which toothpaste containers are made of. Waste water systems are now using aluminum in their systems to help the solids sink to be taken out and of course that means that the fluoride they are adding is going to bind to the leftover aluminum and be ingested by us. I saw that women are many times more likely to be affected by Hashimoto's than a man but I am wondering if men really go to their doctors when they are sick. My hubby has been having all the symptoms of low thyroid but never goes to the doctor.
   A. I don't know enough about the causes of Hashimoto's thyroiditis to make an informed comment about the presence of minerals in food and water supply and the increased risk for this condition. The fact that Hashimoto's thyroditis is several times more common in women than men makes the excess mineral theory less likely to be a cause since one would expect both men and women to be effected in a similar manner since both sexes would ingest a similar amount of these excess minerals.
