Parathyroid Function in Women after Total Thyroidectomy in Thi-Qar, Iraq

Abstract Background: Total thyroidectomy is one of the most important operations currently being performed. It is more common in women than in men, where every eight women meet one man. Objectives: The current study aims to evaluate the decrease in calcium, parathyroid hormone (PTH), and vitamin D in patients with total thyroidectomy, in relation to the periods after the operation. Materials and Methods: The study included the presence of three groups of patients, with different characteristics in terms of time after the total removal of the thyroid gland, and a fourth group as the healthy control group, with each group consisting of 30 samples. Results: The results revealed that the concentration of PTH levels showed a significant decrease in the patient groups in comparison with the control group. The results also revealed that the concentration of calcium levels showed a significant decrease in the patient groups in comparison with the control group, and the results showed a significant decrease in the first group of patients when compared with the other group of patients. The concentration of vitamin D levels showed a significant decrease in the patient groups in comparison with the control group. Predictive factors of hypoparathyroidism after thyroidectomy are important because of the role of PTH and its effect on the concentration of calcium and vitamin D. The current study has shown clear changes after total thyroidectomy. Conclusion: According to the findings, measuring serum calcium, PTH, and vitamin D after surgery, reducing the duration of surgery, and female gender are among the predictive factors of postoperative hypoparathyroidism after thyroidectomy.
