| Question | Answer |
| What hormone does the hypothalamus secrete when thyroid levels drop too low? | Thyroid Stimulating Releasing Hormone (TRH) |
| What does the TRH hormone do to the pituitary gland? | Stimulates pituitary gland to secrete Thyroid Stimulating Hormone (TSH) |
| What affect does the TSH hormone have on the thyroid gland | Triggers thyroid to produce thyroxine (T4) and triiodothyronine (T3) |
| T3 & T4 hormones are made using what chemical? | Iodine |
| What is the function of T3 and T4? | To stimulate body's metabolism by promoting body cells to produce protein |
| What is the result of an increased cellular metabolism? | - Increased heart rate - Tissue growth - Body development - Heat production - energy consumption |
| Other than T3 and T4 what are the other two hormones produced by the thyroid gland? | Calcitonin and Parathyroid hormone |
| What is the function of these two hormones? | To promote bone health, tissue and muscle function |
| What is hyperthyroidism? | A disorder caused by an overactive thyroid (over production of hormones) |
| What may cause hyperthyroidsim? | - Excess iodine - Thyroid inflammation (hormone leakage) - Thyroid nodules (benign tumours) - Too much L-Thyroxine (in the form of supplements) |
| What are some symptoms of hyperthyroidism? | - Increased appetite - Nervousness - Restlessness - Weakness - Irregular heartbeat |
| What is hypothyroidism? | A disorder caused by an under active thyroid (an under production of hormones) |
| What may cause hypothyroidism? | - Having an autoimmune disease - Hyperthyroidism treatment - Thyroid surgery - Radiation - Medication e.g. Lithium |
| What are some symptoms of hypothyroidism? | - Puffy face - Dry skin - Fatigue - Weight gain - Hoarseness |
| Who is most at risk of hypothyroidism? | - Women - People over 60 - White or Asian people - People with an autoimmune disease - People with chromosomal abnormalities - People experiencing hormonal changes |
| Who is most at risk of hyperthyroidism | - Women - People over 60 - Having a recent pregnancy - People with an autoimmune disease - Family/personal thyroid disorder history |
| How is hyperthyroidism diagnosed? | Either through a medical history check (family included) or through blood test which measure TSH level |
| How is hypothyroidism diagnosed | Blood test measures level of TSH - High level = Hyperthyroidism - Low level = Hypothyroidism |
| What are the four methods of treatment for hyperthyroidism? | - Radioactive iodine - Anti-thyroid medications - Beta blockers - Thyroidecomy |
| How does radioactive iodine work & what are the side effects? | Taken orally & reduces inflammation side effect: May cause hyPOthyroidism |
| How does anti-thyroid medication work & what are the side effects? | Reduces symptoms by preventing hormone production side effects: Liver damage, fever, joint pain |
| How do Beta blockers work & what are the side effects? | Treats blood pressure and heart rate to prevent heart palpitations side effects: Nausea, dizziness,fatigue |
| How does thyroidectomy work & what are the side effects? | Removal of most of the thyroid side effects: damage to vocal chords and parathyroid gland - may require medication for calcium level regulation |
| What is the treatment for hypothyroidism -how does it work -what are the symptoms? | Daily use of LEVOTHYROXINE Restores hormone levels & reverses symptoms SE: appetite, insomna, heart palpitation |
