Endemic Goitre
Endemic goitre is a type of goitre that is associated with dietary iodine deficiency. Cause Some inland areas, where soil and water lacks iodine compounds and consumption of marine foods is low, are known for higher incidence of goitre. In such areas goitre is said to be "endemic". Prevention This type of goitre is easily preventable. In most developed countries regulations have been put into force by health policy institutions requiring salt, flour or water to be fortified with iodine. Treatment Treatment of endemic goitre is medical with iodine and thyroxine Thyroxine, also known as T4, is a hormone produced by the thyroid gland. It is the primary form of thyroid hormone found in the blood and acts as a prohormone of the more active thyroid hormone, triiodothyronine (T3). Thyroxine and its acti ... preparations. Surgery is only necessary in cases that are complicated by significant compression of nearby structures. References {{DEFAULTSORT:Endemic Goiter M ...

Iodine Deficiency
Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet. It may result in metabolic problems such as goiter, sometimes as an endemic goiter as well as congenital iodine deficiency syndrome due to untreated congenital hypothyroidism, which results in developmental delays and other health problems. Iodine deficiency is an important global health issue, especially for fertile and pregnant women. It is also a preventable cause of intellectual disability. Iodine is an essential dietary mineral for neurodevelopment among children. The thyroid hormones thyroxine and triiodothyronine contain iodine. In areas with little iodine in the diet, typically remote inland areas where no marine foods are eaten, deficiency is common. It is common in mountainous regions where food is grown in iodine-poor soil. Prevention includes adding small amounts of iodine to table salt, a product known as ''iodized salt''. In areas of deficiency, iodine compounds have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goitre
A goitre (British English), or goiter (American English), is a swelling in the neck resulting from an enlarged thyroid gland. A goitre can be associated with a thyroid that is not functioning properly. Worldwide, over 90% of goitre cases are caused by iodine deficiency. The term is from the Latin ''gutturia'', meaning throat. Most goitres are not cancerous ( benign), though they may be potentially harmful. Signs and symptoms A goitre can present as a palpable or visible enlargement of the thyroid gland at the base of the neck. A goitre, if associated with hypothyroidism or hyperthyroidism, may be present with symptoms of the underlying disorder. For hyperthyroidism, the most common symptoms are associated with adrenergic stimulation: tachycardia (increased heart rate), palpitations, nervousness, tremor, increased blood pressure and heat intolerance. Clinical manifestations are often related to hypermetabolism (increased metabolism), excessive thyroid hormone, an in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Iodine
Iodine is a chemical element; it has symbol I and atomic number 53. The heaviest of the stable halogens, it exists at standard conditions as a semi-lustrous, non-metallic solid that melts to form a deep violet liquid at , and boils to a violet gas at . The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years later by Joseph Louis Gay-Lussac, after the Ancient Greek , meaning 'violet'. Iodine occurs in many oxidation states, including iodide (I−), iodate (), and the various periodate anions. As the heaviest essential mineral nutrient, iodine is required for the synthesis of thyroid hormones. Iodine deficiency affects about two billion people and is the leading preventable cause of intellectual disabilities. The dominant producers of iodine today are Chile and Japan. Due to its high atomic number and ease of attachment to organic compounds, it has also found favour as a non-toxic radiocontrast material. Because of the spec ...

Seafood
Seafood is any form of Marine life, sea life regarded as food by humans, prominently including Fish as food, fish and shellfish. Shellfish include various species of Mollusca, molluscs (e.g., bivalve molluscs such as clams, oysters, and mussels, and cephalopods such as octopus and squid), crustaceans (e.g. shrimp, crabs, and lobster), and echinoderms (e.g. sea cucumbers and sea urchins). Historically, marine mammals such as cetaceans (whales and dolphins) as well as Pinniped, seals have been eaten as food, though that happens to a lesser extent in modern times. Edible sea plants such as some Edible seaweed, seaweeds and microalgae are widely eaten as :edible seaweeds, sea vegetables around the world, especially in Asia. Seafood is an important source of (animal) protein in many Diet (nutrition), diets around the world, especially in coastal areas. Semi-vegetarianism, Semi-vegetarians who consume seafood as the only source of meat are said to adhere to pescetarianism. The harv ...

Endemic (epidemiology)
In epidemiology, an infection is said to be endemic in a specific population or populated place when that infection is constantly present, or maintained at a baseline level, without extra infections being brought into the group as a result of travel or similar means. The term describes the distribution of an infectious disease among a group of people or within a populated area. An endemic disease always has a steady, predictable number of people getting sick, but that number can be high ('' hyperendemic'') or low (''hypoendemic''), and the disease can be severe or mild. Also, a disease that is usually endemic can become epidemic. For example, chickenpox is endemic in the United Kingdom, but malaria is not. Every year, there are a few cases of malaria reported in the UK, but these do not lead to sustained transmission in the population due to the lack of a suitable vector (mosquitoes of the genus '' Anopheles''). Consequently, there is no constant baseline level of malaria inf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thyroxine
Thyroxine, also known as T4, is a hormone produced by the thyroid gland. It is the primary form of thyroid hormone found in the blood and acts as a prohormone of the more active thyroid hormone, triiodothyronine (T3). Thyroxine and its active metabolites are essential for regulating metabolic rate, supporting heart and muscle function, promoting brain development, and maintaining bone health. Regulation Thyroxine has a half-life of approximately one week and hence maintains relatively stable blood levels. Its production and release are controlled through a complex feedback loop involving the hypothalamus, pituitary gland, and thyroid gland. This regulatory system ensures that optimal hormone levels are maintained. Biosynthesis Thyroxine biosynthesis is a multi-step process that occurs in follicular cell within the thyroid gland. The synthesis of thyroxine requires adequate iodine supply and appropriate hormonal control. The process begins with the active uptake o ...

Mineral Deficiencies
Mineral deficiency is a lack of dietary minerals, the micronutrients that are needed for an organism's proper health. The cause may be a poor diet, impaired uptake of the minerals that are consumed, or a dysfunction in the organism's use of the mineral after it is absorbed. These deficiencies can result in many disorders including anemia and goitre. Examples of mineral deficiency include zinc deficiency, iron deficiency, and magnesium deficiency. Individual deficiency See also *Mineral (nutrient) *Micronutrient deficiency *Vitamin deficiency *Metal toxicity Metal toxicity or metal poisoning is the toxic effect of certain metals that accumulate in the environment and damage ecosystems, plants and animals, including human health.
