Introduction:
The endocrine system regulates the physiological process by secreting different forms of hormones that play major roles in the metabolic regulations. The master gland of the endocrine system is the pituitary gland, whichcontrols all the other glands by releasing stimulating hormones. Thyroid-stimulating hormone is an example of stimulating hormones.

Describe the causes and signs and symptoms of i)hypothyroidism ii) hyperthyroidism. Explain why patients experience these symptoms.
ANSWER SHOULD INCLUDE:
What is thyroxine, and where it is produced in the body? What does thyroxine normally do in the body ? (i.e. what is its function)
Explain why lack of (or excess) thyroxine disrupts these processes; symptoms experienced by people with thyroid disorders.
1. Hypothyroidism- what are the most common causes? Why do patients experience symptoms such as poor ability to tolerate cold temperatures, fatigue, bradycardia, constipation, depression, weight gain? What happens if untreated during pregnancy?
2. Hyperthyroidism - what are the most common causes?. Why do patients experience symptoms such as weight loss, nervousness, weakness, hair loss, goitre, irregular heartbeat, difficulty sleeping?
