Thyroxine
Thyroxine is the main hormone secreted in the blood stream by thyroid gland. It plays an important role in digestion, heart and muscle function, brain development and bone maintenance.

What is Thyroxine?
Thyroxine is the main hormone secreted in the blood stream by thyroid gland. It is an inactive form and most of these are actively converted into an active form called triiodothyronine by the organs such as the liver and kidneys. Thyroid hormonesplay an important role in regulating the body’s metabolic rate, heart and digestive function, muscle control, brain development and bone maintenance.

How is Thyroxine Controlled?
The production and release of thyroid hormone, thyroxacine and triiodothyronine is controlled by a feedback loop system, which involves the hypothalamus in the brain and pituitary and thyroid glands. The hypothalamus passes through thyrotropin-releasing hormone which, in turn, stimulates the pituitary gland to produce thyroid stimulating hormones. This hormone stimulates the production of thyroid hormones, thyroxine and triiodothyronine by thyroid gland.

This hormone stimulates the production of thyroid hormones, thyroxine and triiodothyronine by thyroid gland.
This hormone production system is controlled by the feedback loop so that when the level of thyroid hormone (thyroxine and triiodothyronine) increases, they prevent the release of thyrotropin-releasing hormones and thyroid stimulating hormones. This system allows the body to maintain continuous levels of thyroid hormone in the body.
What if I Have too Much Thyroxine?
The release of excess thyroxine in the blood stream is known as thyrotoxicosis. This may be due to the hyperthyroidism of hyperthyroidism, such as swelling of the grave disease, thyroid or benign tumor. Thyrotoxicosis can be identified by a goiter, which is due to the expansion of the thyroid gland, due to the swelling of the neck. Other symptoms of thyrotoxicosis include heat, weight loss, increased appetite, increased bowel movement, irregular menstrual cycle, fast or irregular heartbeats, tilt, weariness, irritability, shivering, hair loss / loss and retrogression of the eyelids. ‘Stare’ ‘presence.
