Hyperthyroidism is the second most prevalent endocrine disorder next to diabetes mellitus. According to Tierney, et. al. on 2005, it affects women eight times more frequently than men, with onset usually between the second and fourth decades. Thyroid hormones facilitate metabolism. Consequently, if there is an abnormally high level of thyroid hormones (both T3 and T4) in the blood, there will be an increased in demand of oxygen, fast metabolism, and increased vital signs.
In addition, tumor in the pituitary gland, emotional shock, stress, and infection as well as excessive ingestion of thyroid hormones can precipitate the disorder.
1. Due to increased oxygen consumption: insomnia, restlessness, fatigue, irritability, tremors, nervousness, and hyperactivity
2. Due to heat intolerance: sweating, flushed and warm skin
3. Due to increased metabolic rate: weight loss in spite of increased appetite
4. Due to increased cellular metabolism: increased vital signs and peristaltic movement
1. Enlarged thyroid gland
2. Thrill may be palpated and a bruit is heard at the thyroid arteries –sign of increased blood flow to the area
3. Decreased in serum TSH, increased free T4, and increase in radioactive iodine uptake
1. Antithyroid agents – lifetime
2. Radioactive iodine therapy – destroy overactive thyroid cells
