Q. 33

[sthakur115380]

I thought hypo- and hyper- modified the behavior of the thyroid and not the symptomology of the patient. I reasoned that hypothyroidism would involve less calcitonin secretion and hyperthyroidism would involve greater calcitonin secretion, and then attempted to determine what effect that would have on the body.

It says in the passage: “Parathormone and the thyroid hormone calcitonin work antagonistically to regulate the plasma calcium and phosphate levels. Overactive parathyroid glands, hyperparathyroidism, can lead to an increase in the level of calcium in plasma and tissues”. Therefore hyperthyroidism (bold) would involve less calcitonin secretion, thus a higher blood calcium concentration.

Some effects of thyroid conditions are secondary to imbalances in other hormones; others are due to changes in metabolism. Symptoms of hypothyroidism are: fatigue, cold sensitivity, constipation, dry skin/hair/nails, hoarseness, high cholesterol, weight gain, muscle weakness, joint pain and depression. Symptoms of hyperthyroidism (general increase in metabolism) are: weight loss, a rapid or irregular heartbeat, sweating, and nervousness or irritability.
