Thyroxin (sometimes written "thyroxine") is a hormone sectreted by the thyroid gland, which is an endocrine gland in the human body - see the diagram of the locations in the body of the endocrine glands.

Functions of thyroxin :

Thyroxin is important for the regulation of the body's Basal Metabolic Rate (BMR), which is the amount of energy the body uses, just to ‘tick over’.

The consequences of both excessive quantities of thyroxin in the body (hyper-thyrodism), and insufficient thyroxin in the body (hypo-thyroidism), are summarised below:


Hyper-
Thyroidism = ‘over-active thyroid’ = Thyrotoxicosis

Symptoms:

  • increase in BMR
  • increase in heart-rate
  • loss of weight
  • hyper-activity
  • insomniac
  • develops bulging eyes due to accumulation of fluid behind the eye
  • may develop Goitre
  • possible link with Attention Deficit Disorder (speculation).

Hypo-Thyroidism

Symptoms:

  • decrease in BMR
  • weight gain
  • lethargy
  • skin becomes dry and puffy
  • hair becomes thin and brittle.

Can lead to:

  • Derbyshire Neck (originally due to insufficient iodine in the soil in Derbyshire),
  • Graves Disease, and
  • Cretinism (= metal and sexual development imapaired, if occurs in children).
