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 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.
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.
