Final answer:
When the entire thyroid gland is removed, a patient will need lifelong replacement therapy with thyroid hormone medication. Monitoring and adjusting the level of replacement thyroid hormone is important to prevent complications and ensure optimal hormone levels.
Step-by-step explanation:
When a patient undergoes a total thyroidectomy and the entire thyroid gland is removed, they will need lifelong replacement therapy with thyroid hormone medication. This is because the thyroid gland produces hormones that regulate the body's metabolism, and without the gland, the body will not be able to produce enough thyroid hormone on its own. The level of replacement thyroid hormone must be carefully monitored and adjusted because too much or too little hormone can lead to complications.
For example, if the replacement hormone dose is too low, the patient may experience symptoms of hypothyroidism such as fatigue, weight gain, and constipation. On the other hand, if the dose is too high, it can result in symptoms of hyperthyroidism such as irritability, weight loss, and rapid heart rate.
Regular monitoring of thyroid hormone levels through blood tests is important to ensure that the patient is receiving the correct dose of medication. If there are any changes in symptoms or hormone levels, the dosage can be adjusted accordingly to maintain optimal hormone levels and prevent complications.
