Hyperthyroidism Flashcards
1
Q
describe the dysfunction of hyperthyroidism
A
- Occurs when the thyroid gland produces too much thyroxine.
- Hyperthyroidism overstimulates cells causing the body’s metabolic rate to increase.
2
Q
what is the most common form of hyperthyroidism
A
Graves Disease
3
Q
describe what graves disease is
A
- Graves’ disease is an enlargement of the thyroid caused by an immune system reaction.
4
Q
List 5 symptoms of hyperthyroidism
A
- Rapid heartbeat
- Fatigue
- Anxiety
- weight loss
- exophthalmia - in cases of graves disease
5
Q
List 3 forms of treatment for Hyperthyroidism
A
- Anti-thyroid medication
- Radioactive iodine
- Surgery
6
Q
what is Hyperthyroidism surgery specifically called
A
- thyroidectomy
7
Q
describe anti-thyroid medications as a treatment
A
- Anti-thyroid medications can block the thyroid glands from absorbing iodine from the bloodstream
- This stops iodine from being concentrated in thyroid cells and incorporated into molecules to produce hormones.
- Therefore lowering thyroxine production.
8
Q
describe radioactive iodine as a treatment
A
- Drinks containing radioactive iodine can be used.
- The molecules are taken up by the thyroid cells and kill them from its radioactivity
- This reduces the production of thyroxine.
- Cells elsewhere in the body do not absorb the iodine and are not affected.
- This radioactive iodine is eventually excreted via urine.
9
Q
describe surgery as a treatment
A
- Surgery to remove some or all the thyroid glands.
- Less thyroid gland will result in fewer hormones being produced.
10
Q
what makes radioactive iodine user friendly
A
- Reduce the production of thyroxine as they kill the cells of the thyroid.
- Has the best chance of curing the patient of the condition.
- The radioactive iodine only targets the thyroid cells and the other cells do not absorb it
- It is eventually passed out through the urine
11
Q
what makes surgery user friendly
A
- Used on those who are …
- pregnant
- can’t tolerate anti-thyroid drugs
- can’t tolerate radioactive iodine therapy.
- Improves ability to use radioactive iodine after surgery.
- Improves survival in certain patients.
12
Q
what makes anti-thyroid medications user friendly
A
- Reduce symptoms of hyperthyroidism by restricting the production of excess thyroxine
- Don’t do any permanent damage to the thyroid gland.
- In some people the drug clears up the symptoms permanently.
13
Q
what are the risks of using anti-thyroid medications
A
- Can cause liver damage which can lead to death.
- There is a chance for some people to experience a relapse.
14
Q
what are the risks of using radioactive iodine
A
- The treatment kills excessive amounts of the thyroid cells causing an insufficient production of hormones leading to hypothyroidism
- Metallic taste in the mouth which can last a couple of weeks.
- Nausea is experienced for only 1 or 2 days after treatment.
- Swollen salivary glands.
15
Q
what are the risks of participating in surgery
A
- Damage to the vocal cords and parathyroid glands.
- If the parathyroid glands are removed medication must be taken to control the calcium and phosphate levels in the blood.
- Can lead to the patient experiencing hypothyroidism as the thyroid is removed.
