Iodine Deficiency Disorders | Iodine | Cretinism | Iodized Salt Iodine is found in the earth's crust in sparse amounts and is in the form of iodide. Neonates and young infants constitute the target population for the effects of iodine deficiency because, from a public health viewpoint, the most important complications of iodine deficiency are irreversible brain damage and mental retardation which result from iodine deficiency and thyroid failure during fetal and early postnatal life. The principal complication of iodine prophylaxis is the occurrence of thyrotoxicosis (hyperthyroidism). www.thyroid.ca /Articles/iodine.html   (810 words)

Iodine - Wikipedia, the free encyclopedia Iodine (from the Greek word Iodes, meaning "violet"), is a chemical element in the periodic table that has the symbol I and atomic number 53. Iodine is primarily used in medicine, photography and in dyes. Iodine pills are sometimes distributed to persons living close to nuclear establishments, for use in case of accidents that could lead to releases of radioactive iodine. en.wikipedia.org /wiki/Iodine   (1682 words)

Iodine Deficiency Iodine deficiency is caused by a lack of iodine, a chemical element essential to the body's physical and mental development, in a person's diet. The incidence of iodine deficiency occurs in certain geographical areas at higher altitudes with iodine depleted soil - usually in areas away from the seacoast and in countries where salt is not fortified with iodine. Iodine is an essential element for thyroid function, necessary for the normal growth, development and functioning of the brain and body. www.med.umich.edu /1libr/aha/umioddef.htm   (693 words)

SPECIFIC IODINE DEFICIENCY DISORDERS Thyroid hyperplasia induced by iodine deficiency is associated with an altered pattern of thyroid hormonogenesis: the abnormal configuration of the poorly iodinated thyroglobulin in the thyroid colloid is accompanied by an increase in poorly iodinated compounds, monoiodotyrosine (MIT) and T3, and a decrease in diiodotyrosine (DIT) and T4. Iodine deficiency is, as for the neurologic type, a perequisite in the etiology of the disorder. It has been recently proposed that the combination of deficiencies in iodine and Selenium and SCN overload are required for explaining the occurrence of severe thyroid failure during the perinatal period with as longterm consequence the development of the myxedematous type of endemic cretinism (87). www.thyroidmanager.org /Chapter20/ch01s03.html   (4796 words)

AllThyroid.org: Thyroid Disorders & Treatments This tragic disorder results from extreme iodine deficiency - affected children are born with such marked mental and physical retardation, including deaf mutism and dwarfism, that they never can be productive members of their society. However, there is some data that suggests that lack of iodine is common in some areas, and may have worsened the effect of the Chernobyl accident on inhabitants of that region. Therefore, if you are pregnant and ingest large quantities of iodine in the form of a medication, kelp, or another form of seaweed, you risk having your baby born with a goiter and possibly with an underactive thyroid as well. www.tsh.org /disorders/iodine/iodine.html   (1398 words)

Iodine Deficiency Control Iodine intake will also be assessed, and the knowledge and perceptions of community members regarding IDD and the iodization of salt will be investigated. The goal of the study was to determine the prevalence of iodine deficiency disorders (IDD) in high risk groups (women of reproductive age and adolescents) in the city of Bombay. Estimations of dietary iodine questioned the validity of using the iodine content of raw foods for computing the iodine intake, as significant losses were recorded in processing and cooking. www.idrc.ca /es/ev-4368-201-1-DO_TOPIC.html   (733 words)

eMedicine - Iodine Deficiency : Article by Stephanie L Lee   (Site not responding. Last check: 2007-10-17) Whether iodine deficiency causes an increased risk for thyroid cancer is unclear, but a higher proportion of more aggressive thyroid cancers (ie, follicular thyroid carcinoma) and an increased thyroid cancer mortality rate are found in areas where iodine deficiency is endemic. Myxedematous cretinism is considered a result of iodine deficiency and hypothyroidism in the fetus during late pregnancy or in the neonatal period, resulting in mental retardation, short stature, goiter, and hypothyroidism (see Image 3). Mental retardation as a result of iodine deficiency can be exaggerated in the setting of concomitant deficiencies of selenium or vitamin A. Postnatally, as infants and children are particularly sensitive to fluctuations in iodine intake, this population is at risk for poor mental and psychomotor development (predominantly in language and memory skills). www.emedicine.com /med/topic1187.htm   (4412 words)

Iodine Deficiencies of this essential trace element appear to be associated with many diseases, or birth defects, including goitre, cretinism, multiple sclerosis, amyotrophic lateral sclerosis and cancer of the thyroid and nervous system. In 1990, iodine deficiency affected almost one-third of the world population and was the greatest single cause of preventable brain damage and mental retardation. Iodine supplementation is followed by an increased prevalence of occult papillary carcinoma of the thyroid discovered at autopsy but the prognosis of thyroid cancer is improved due to a shift towards differentiated forms of thyroid cancer that are diagnosed at earlier stages. www.ithyroid.com /iodine.htm   (7833 words)

International Council for the Control of Iodine Deficiency Disorders Iodine deficiency is the single most common cause of preventable mental retardation and brain damage in the world. Iodine deficiency was once considered a minor problem, causing goiter, an unsightly but seemingly benign cosmetic blemish. Iodine excess is undesirable, but its consequences are not nearly so severe as those of iodine deficiency, because the latter affects human development and can produce permanent brain damage. www.people.virginia.edu /~jtd/iccidd/aboutidd.htm   (3238 words)

Iodine Deficiency Mild iodine deficiency has been reported to reduce intelligence quotients (I.Q.) by 10-15% (15, 25, 81) and cause increased rates of stillbirths, perinatal mortality, and infant mortality (36, 54).

THE MERCK MANUAL, Sec. 1, Ch. 4, Mineral Deficiency And Toxicity The primary function of iodine (I) in the body is to provide a substrate for the synthesis of the thyroid hormones, thyroxine and triiodothyronine, which are crucial for normal growth and development. These events account for the continued depletion of iodine in soil, its lack of capture by plants, and continuing iodine deficiency in humans, particularly at higher altitudes in countries where salt is not fortified with iodide. Deficient adults are given iodide at a dose of 1500 µg/day--about 10 times the recommended daily allowance--for several weeks to restore the iodine content of the depleted gland and permit thyroxine synthesis. www.merck.com /pubs/mmanual/section1/chapter4/4c.htm   (534 words)

WHO | Eliminating iodine deficiency worldwide is within reach Iodine deficiency is a significant cause of mental developmental problems in children. Cretinism is the most extreme manifestation of iodine deficiency, but the primary motivation behind the current worldwide drive to eliminate iodine deficiency is the more subtle degree of mental and neurological impairment leading to poor school performance, reduced intellectual ability and impaired work capacity. The report is based on the WHO Global Database on Iodine Deficiency, which compiles data on urinary iodine concentration and the prevalence of goitre (enlarged thyroid gland) and monitors the magnitude, severity and distribution of iodine deficiency worldwide. www.who.int /mediacentre/news/releases/2004/pr93/en   (704 words)

Iodine Iodine, consumed principally as its iodide salts, is an essential trace element which is vital to the function of the thyroid gland. Iodine is present in low amounts in the earth's crust and thus in its soil. Iodine deficiency is the most common cause of preventable mental deficit in the world. www.pdrhealth.com /drug_info/nmdrugprofiles/nutsupdrugs/iod_0146.shtml   (2331 words)

Iodine deficiency Iodine deficiency is the world's leading cause of mental retardation in children. Lack of iodine is a major problem in developing countries and is considered to be the world's number one cause of preventable intellectual disability in children. Iodine is found in seawater, so any type of seafood is a rich source of this element, particularly seaweed (e.g kelp). www.healthyeatingclub.com /info/articles/Minerals/iodine.htm   (844 words)

Iodine Deficiency in Saudi Arabia Data on the status of iodine deficiency in the Arabian peninsula is scarce. The term iodine deficiency disorders (IDD) covers a wide variety of clinical conditions affecting the health and well-being of man. About one-third of the world's population, 1.57 billion people, live in iodine-deficient environments and are thus at risk of IDD.

Flechas Family Practice Iodine is also concentrated by breast tissue, and a lack of iodine in the breasts manifests as fibrocystic breast disease (painful breasts with nodules and cysts and often more symptomatic prior to menstrual periods). Iodine can be concentrated in the ovaries, and Russian studies done some years ago showed a relationship between iodine deficiency and the presence of cysts in the ovaries. Iodine supplementation may alleviate these iodine-related maladies, but iodine testing and thyroid studies such as a thyroid ultrasound and thyroid lab tests should be conducted prior to beginning iodine supplementation therapy. www.helpmythyroid.com /iodine.htm   (1741 words)

Iodine Deficiency   (Site not responding. Last check: 2007-10-17) Dr. Brownstein believes that iodine deficiency is a major cause of breast cancer and other diseases of the reproductive organs such as ovarian, uterus and prostrate cysts and cancers. Iodine levels in US soil have fallen 50 per cent over the past 50 years and soil in the US is deficient in iodine. Iodine can similarly reduce uterine fibroids and one of the first conventional medical treatments for severe fibroids was to paint the uterus with iodine. www.vitamincfoundation.org /iodine.htm   (906 words)

Iodine Deficiency Reported in Vegetarians and Vegans: An All-Creatures Health Archives Article - diet, disease, ... Quoting from the paper: "One fourth of the vegetarians and 80% of the vegans suffer from iodine deficiency..." Only 9% of the meateaters were deficient. The milk drinkers were protected in part because iodine containing disinfectants are used to clean the milk processing equipment which kind of leach into the milk. Iodine deficiency was actually a prevalent problem in the U.S. before the iodization of salt became a common practice in the 1920's.[2] www.all-creatures.org /health/iodinedef.html   (494 words)

Iodine Benefits & Iodine Deficiency Symptoms   (Site not responding. Last check: 2007-10-17) Iodine is called the "metabolizer." Iodine is one of the most vital of the biochemical elements and has one of the highest vibratory frequency rates of all the elements. Iodine mainly affects the thyroid, which not only controls many important functions in the body, but also keeps us in a quickened state of health. Iodine is stored mostly in the thyroid and in smaller amounts in the muscles, skin and bones. www.healthcatchers.com /iodine.html   (224 words)

Iodine deficiency - WrongDiagnosis.com Iodine is needed by the thyroid gland for healthy functioning. However, iodine deficiency is much less common in industrialized nations due to the addition of iodine to table salt. With a diagnosis of Iodine deficiency, it is also important to consider whether there is an underlying condition causing Iodine deficiency. www.wrongdiagnosis.com /i/iodine_deficiency/intro.htm   (347 words)

Iodine deficiency: Testing yourself, and treatment - thyroidstory.mivox.com The aforementioned "iodine loading test" operates on the premise that your body flushes out excess iodine in the urine, so patients are given 4 iodoral tablets, and then their urine is measured for iodine content over the next 24 hours. I have heard that iodine supplementation is generally not recommended for hashimotos thyroiditis patients (which is usually diagnosed with a thyroid antibody test). All of these conditions have been shown in the literature to be associated with iodine deficiency.3 Positive clinical results were seen in most of these patients after supplementation of orthoiodosupplementation within the range of 6.25-50mg of iodine/iodide (1/2 to 4 tablets of Lugol in tablet form). thyroidstory.mivox.com /mivox/supplements/iodine_deficiency_testing_yourself_and_treatment   (3958 words)

Iodine The World Bank has estimated that iodine deficiency, in combination with vitamin A deficiency and iron deficiency, may lower the economic wealth of a nation by as much as 5% every year. There is an urgent need for corrective measures, to safeguard the populations, especially pregnant and lactating women and infants and young children, from the deleterious effects of iodine deficiency. Iodine levels in the water were low 2mg/L  (normal range >5 mg /L) Goiter was graded according to the WHO categories and blood protein iodine. nutrition.tufts.edu /conferences/childhood/iodine.htm   (499 words)

Iodized Salt Salt producers are a key partner in combating Iodine Deficiency Disorders (IDD) today throughout the world as agreed at a recent major IDD summit in Beijing (1 2). The "hidden hunger" of iodine deficiency causes a 10-15% reduction in a population's IQ capability, mental retardation and cretinism. Loss of iodine from iodized salt produced and sold in the United States is not a concern because producers use moisture-proof packaging and add stabilizers; and storage conditions in the grocery distribution system are suitable. saltinstitute.org /37.html   (1198 words)

childinfo.org: Iodine deficiency disorders (IDD) has seen dramatic progress in the campaign to eliminate iodine deficiency, the world's leading cause of preventable mental retardation and impaired psychomotor development in young children. Most commonly and visibly associated with goitre, iodine deficiency takes its greatest toll in impaired mental growth and development, contributing in turn to poor school performance, reduced intellectual ability, and impaired work performance. An estimated 43 million were affected by some degree of brain damage as a result of inadequate iodine intake before or during infancy and early childhood - largely the consequence of living in mountainous or flood-plain regions where erosion has caused the local soil and crops contain too little iodine for healthy thyroid function. www.childinfo.org /areas/idd   (419 words)

UNICEF CEE/CIS - Iodine Deficiency (ID) - The Issue Iodine can be found in food that is grown or raised on iodine-rich soil. But in areas where the soil lacks iodine – the case in a significant proportion of our region – adding iodine to salt is the answer. In a region that needs every citizen to perform at peak capacity if it is to make lasting progress, iodine deficiency is a serious barrier to development. www.unicef.org /ceecis/iodine_deficiency.html   (323 words)
