Endocrine System

The endocrine system is the gland system in the body that produces hormones. It concerns metabolism, tissue function, growth and can also affect mood. The system regulates the body, so conditions that affect it can have a major impact on training and daily life. We look at conditions like hypothyroidism and hyperthyroidism, discussing their symptoms and treatment.

Hypothyroidism

Hypothyroidism is also known as an underactive thyroid gland. The thyroid gland is found in the neck and produces the hormone thyroxine which controls how much energy your body is using. Hypothyroidism is when the gland doesn't produce enough of this hormone. This condition is most common in women and is normally caused when the immune system attacks the thyroid gland.

Hyperthyroidism

Hyperthyroidism is also known as an overactive thyroid (or sometimes thyrotoxicosis). The thyroid gland is found in the neck and is responsible for the production of the chemical Thyroxine which controls energy levels. Hyperthyroidism is when too much of this chemical is produced.
