Medical Surgical Parathyroid #1

Question

Which will contribute to secondary hypoparathyroidism?

Answers

  1. Esophageal cancer
    • Rationale:

      This answer is not correct because esophageal cancer is not a cause of hypoparathyroidism. Secondary hypoparathyroidism is most commonly associated with thyroidectomy.

  2. Thyroidectomy
    • Rationale:

      This answer is correct because secondary hypoparathyroidism is most commonly associated with thyroidectomy. This occurs due to the fact that the parathyroids are attached to the thyroid. Symptoms of hypoparathyroidism are the same as hypocalcemia. Symptoms most associated with hypoparathyroidism are laryngeal spasms, hypocalcemia, positive Trousseau and Chvostek signs, tetany, fatigue, muscle cramps, paresthesia or burning in the toes, fingertips, or lips, hair loss, dry skin and nails, and depression, or anxiousness.

  3. Kidney failure
    • Rationale:

      This answer is not correct because kidney failure is not a cause of hypoparathyroidism. Secondary hypoparathyroidism is most commonly associated with thyroidectomy.

  4. Above the knee amputation
    • Rationale:

      This answer is not correct because above the knee amputation is not a cause of hypoparathyroidism. Secondary hypoparathyroidism is most commonly associated with thyroidectomy.

Overview

Hypoparathyroidism is a condition where the body doesn’t produce enough parathyroid hormone (PTH). Hypoparathyroidism can be caused by the complete removal of the thyroid, or thyroidectomy.

Explanation

Learning Outcomes

Hypoparathyroidism is a condition where the body doesn’t produce enough parathyroid hormone (PTH). PTH is instrumental in regulating and balancing phosphorus and calcium. Primary hypoparathyroidism is rare but secondary hypoparathyroidism is most commonly associated with thyroidectomy. This occurs due to the fact that the parathyroids are attached to the thyroid. Symptoms of hypoparathyroidism are the same as hypocalcemia. Symptoms most associated with hypoparathyroidism are laryngeal spasms, hypocalcemia, positive Trousseau and Chvostek signs, tetany, fatigue, muscle cramps, paresthesia or burning in the toes, fingertips, or lips, hair loss, dry skin and nails, and depression, or anxiousness.
