Introduction to Hypothyroidism and the Endocrine System

The Endocrine System

Humans, like all mammals, are composed of millions of cells, collections of which are highly specialised. We must live, grow, sustain ourselves and reproduce to continue the species. Reproduction itself is a complex process leading to conception, cell proliferation, and the development of a new male or female baby. The new human must grow and in turn, perhaps, have his or her own child.

Brief Introduction To Hypothyroidism

Hypothyroidism occurs when someone does not have enough effect of the biologically active T3 thyroid hormone within the cells of their body.

It can be caused by low thyroid hormones, poor conversion from T4 to T3, or other more subtle reasons like thyroid hormone resistance, or hypocortisolism.

In some parts of the world and even in some parts of the same country, iodine deficiency in the soil can lead to iodine deficiency in people. Iodine deficiency can lead to hypothyroidism because the thyroid gland uses iodine to make thyroid hormone.
