Levothyroxine is the medicine given for treating hypothyroidism. Pictures of Thyroxine : Images, Pics, Pictures and Photos of Thyroxine.
In addition, it also controls various physiological activities and help in heat generation in the body. In animals, thyroxine is responsible for hibernation period and it controls the molting behavior in birds.

What is thyroxine? Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It is the inactive form and most of it is converted to an active form called triiodothyronine by organs such as the liver and kidneys.
May be caused by overactivity of the thyroid gland ( hyperthyroidism as in Graves' disease, inflammation of the thyroid or a benign tumour. Thyrotoxicosis can be recognised by a goitre which is a swelling of the neck due to enlargement of the thyroid gland. Other
The cause is unknown. Thyroid hormones are essential for physical and mental development so hypothyroidism during development or before birth and during childhood causes mental impairment and reduced physical growth. Hypothyroidism in adults causes a decreased metabolic rate. This
When thyroxine level crosses the limit and circulates in excess, this condition is called hyperthyroidism (Graves disease). Similarly, when the level is below 4.5 then this condition is called hypothyroidism, which arises due to deficiency of thyroxine.
Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones. Alternative names for thyroxine T4; tetraiodothyronine; thyroxin.
System allows the body to maintain a constant level of thyroid hormones in the body. What happens if I have too much thyroxine? The release of too much thyroxine in the bloodstream is known as thyrotoxicosis. This

Excess of Thyroxine : In one deciliter of blood, there should be mcg of thyroxine in blood. This is considered as standard level of this hormone and anything lesser than and higher than this normal level is dangerous.
Hence the thyroxine hormone should be at the optimal level for normal health. Function : Thyroid hormone is responsible for circulating the protein content in the blood. Most of the hormones will contain certain amount of protein and only some of them are free circulating still biologically active.
What happens if I have too little thyroxine? Too little production of thyroxine by the thyroid gland is known as hypothyroidism. It may be caused by autoimmune diseases, poor iodine intake or brought on by the use of certain drugs. Sometimes,
Results in symptoms which include fatigue, intolerance of cold temperatures, low heart rate, weight gain, reduced appetite, poor memory, depression, stiffness of the muscles and infertility. Reviewed: January 2015).
They will also have symptoms of difficulty in concentration, loss of memory and sleeping sickness. They are more prone to heart attack and stroke than normal individuals. In hyperthyroidism, the thyroxine per deciliter crosses the normal range which may cause serious health complications.

Thyroxine is the name of the hormone secreted by thyroid gland which does the work of metabolic activities. It also controls the rate of oxidation level in the cells. Thyroxine hormone contains 65 iodine which is necessary for the production of T3 and T4 (tyrosine) hormones.

Further their nails will be rising up in the edges signifying Plummers nail condition. Their pulse rate will be very high with increased palpitation. Treatment : Doctors would administer T3 and T4 hormones to treat deficiency of thyroxine.
Hence thyroxine carries out the job of plasma transport to all the cells in your body. Thyroid hormone cannot get through cell membranes like that of lipophilic substances. The primary function of thyroxine is to control the metabolic rate in our body.
Thyroid hormones play vital roles in regulating the bodys metabolic rate, heart and digestive functions, muscle control, brain development and maintenance of bones. How is thyroxine controlled? The production and release of thyroid hormones, thyroxine and triiodothyronine, is controlled by a feedback loop system which involves the hypothalamus in the brain and the pituitary and.
