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. [1] The thyroid hormones thyroxine and triiodothyronine contain iodine. In areas with little iodine in the diet ...
Hypothyroidism is more common in women than in men. [3] People over the age of 60 are more commonly affected. [3] Dogs are also known to develop hypothyroidism, as are cats and horses, albeit more rarely. [13] The word hypothyroidism is from Greek hypo-'reduced', thyreos 'shield', and eidos 'form', where the two latter parts refer to the ...
Grass is a natural source of nutrition for a horse. Equine nutrition is the feeding of horses, ponies, mules, donkeys, and other equines. Correct and balanced nutrition is a critical component of proper horse care. Horses are non-ruminant herbivores of a type known as a "hindgut fermenter." Horses have only one stomach, as do humans.
Around the world, the most common cause of congenital hypothyroidism is iodine deficiency, but in most of the developed world and areas of adequate environmental iodine, cases are due to a combination of known and unknown causes. Most commonly there is a defect of development of the thyroid gland itself, resulting in an absent (athyreosis) or ...
Soil deficient in iodine is most common inland, in mountainous areas, and in areas of frequent flooding. It can also occur in coastal regions, where iodine might have been removed from the soil by glaciation, as well as leaching by snow, water and heavy rainfall. [12] Plants and animals grown in iodine-deficient soils are correspondingly deficient.
In older patients, emotional instability may be less evident, or depression may occur, and the symptoms and signs are manifestly circulatory. In many, the thyroid is not readily palpable. [4] Symptoms such as rapid heart rate, shortness of breath on exertion, and edema may predominate. Older patients also tend to have more weight loss and less ...
Common symptoms of food poisoning include stomach aches and pain, nausea, fever, vomiting, diarrhea and headache. "Those most at risk for severe foodborne illness include children under 5 ...
T 3 and T 4 are partially composed of iodine, derived from food. [2] A deficiency of iodine leads to decreased production of T 3 and T 4, enlarges the thyroid tissue and will cause the disease known as simple goitre. [3] The major form of thyroid hormone in the blood is thyroxine (T 4), whose half-life of around one week [4] is longer than that ...
