T3, T4 are two hormones of thyroid secretion, named four iodothyronine (abbreviated as T4, thyroxine that is commonly referred to) and three-triiodothyronine (abbreviated as T3), both collectively known as thyroid hormone , amino acid derivatives which are iodinated, so they have to use "T" to represent.These two hormones are in effect on the body play a catalytic role in enhancing the main.Increased (hyperthyroidism), the metabolic rate to accelerate, prompting the diet increased while consumption also increased, people generally seem thin;The contrary when low, slow down the metabolic dysfunction, metabolic rate, resulting in loss of appetite and other phenomena, their body fat in obese patients significantly more simple, compared with normal under normal circumstances, In the cases surveyed did not find T3, T4 is low, but the proportion with respect to the body, the relative lack nothing now and the end of the study data show significant changes in the Obese T3, T4's.Interestingly, the information then prove that hypothyroidism who, and no significant obesity, which may be related to poor patients suffering from T3,1,4 while anorexia symptoms.There are also people sometimes low thyroid function, Klotz (K1otz) found in 240 obese people have a 22% occurrence of hypothyroidism, but the majority of cases, obesity improves after thyroid function return to normal
One of the thyroid hormones involved in the maintenance of metabolic homeostasis.Synthesized and stored as amino acid residues of thyroglobulin, the major protein component of the thyroid follicular colloid.Synthesis and secretion are regulated by the p.
Levothyroxine is used to treat an underactive thyroid (hypothyroidism).It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland.Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery.Having enough thyroid hormone is important for maintaining normal mental and physical activity.In children, having enough thyroid hormone is important for normal mental and physical development.
This medication is also used to treat other types of thyroid disorders (such as certain types of goiters, thyroid cancer).
