The thyroid is a small gland, shaped like a butterfly, which rests in the middle of the lower neck. Its primary function is to control the body's metabolism (rate at which cells perform duties essential to living). To control metabolism, the thyroid produces hormones, T4 and T3, which tell the body's cells how much energy to use. A properly functioning thyroid will maintain the right amount of hormones needed to keep the body's metabolism functioning at a satisfactory rate. As the hormones are used, the thyroid creates replacements.
When the thyroid produces too much hormone, the body uses energy faster than it should. This condition is called hyperthyroidism. When the thyroid doesn't produce enough hormones, the body uses energy slower than it should. This condition is called hypothyroidism. There are many different reasons why either of these conditions might develop.
Thyroid dysfunction came in appearance significantly after use of iodised salt in plain areas other than hill stations because we are in constant exposure of the things which are avoidable (other than salt) and harmful for us either mentally or physically. So to treat dysfunctions related to thyroid we need to understand all these things. After understanding the cause of deviation we treat/cure the thyroid and simultaneously relieve you from any kind of hormonal medicaments/ pills which you might be taking.
