Correct Answer Is Option = Goitre
Notes / Explanation
The deficiency of iodine in the body causes the disease known as goitre, which involves a swelling in the neck due to the enlargement of a particular gland. Iodine is a substance that the body needs in small amounts, and it is required for the proper working of a gland located in the neck, which produces certain substances that are important for the regulation of many of the body's processes. When the body does not get enough iodine, this gland is unable to work properly, and it may become enlarged as it tries to compensate for the lack of iodine, causing a swelling in the neck, which is the condition known as goitre. The lack of iodine and the resulting problems with this gland can also have other effects on the health of the body, because the substances produced by this gland are important for many of the body's functions, including growth and development and the regulation of the body's processes, so that a lack of iodine, particularly in children and during development, can have serious effects. Iodine is obtained from the diet, and it is found in certain foods, particularly foods from the sea, such as seafood, and it is present in varying amounts in other foods depending on the soil in which they are grown. In regions where the soil and the local foods are low in iodine, a deficiency of iodine was in the past common, leading to goitre and other problems. To prevent iodine deficiency, iodine is commonly added to ordinary table salt, so that the salt used in food provides the iodine that the body needs, and this has been very effective in preventing iodine deficiency and the diseases it causes. The study of the substances the body needs, including iodine, and the diseases caused by their lack is an important topic. For PPSC and other competitive examinations, the key points to remember are that the deficiency of iodine in the body causes the disease goitre, which involves a swelling in the neck due to the enlargement of a gland located there, that iodine is needed for the proper working of this gland, which produces substances important for the regulation of many of the body's processes, and that iodine is obtained from the diet, particularly from foods from the sea, and is commonly added to table salt to prevent deficiency. This is a health-related topic, and anyone with concerns about their health should seek advice from a qualified medical professional.
