Female gender as a risk factor for transient post-thyroidectomy hypocalcemia

Area of Science:

• Endocrinology
• Surgical Complications
• Calcium Metabolism

Background:

• Transient post-thyroidectomy hypocalcemia is a common complication after thyroid surgery.
• Identifying risk factors is crucial for predicting and potentially preventing hypocalcemia.
• Patient gender has been explored as a potential contributing factor.

Purpose of the Study:

• To evaluate the role of patient gender as a risk factor for transient post-thyroidectomy hypocalcemia.
• To determine if there is a significant difference in hypocalcemia incidence between genders following total thyroidectomy.

Main Methods:

• Retrospective case series with chart review of 270 total thyroidectomy patients.
• Included 219 women and 51 men, analyzing postoperative hypocalcemia rates.
• Assessed confounding factors including age, menopausal status, and preoperative biochemical levels.

Main Results:

• Female patients experienced a significantly higher incidence of transient post-thyroidectomy hypocalcemia (24.7%) compared to male patients (11.8%).
• The relative risk ratio for females was 2.1 (confidence interval, 1.0-4.6), indicating a higher risk.
• No significant difference in hypocalcemia rates was observed between premenopausal and postmenopausal women.

Conclusions:

• Female gender appears to be a statistically significant risk factor for transient post-thyroidectomy hypocalcemia.
• The clinical relevance and magnitude of this gender-associated risk require further investigation.
• Additional research is needed to elucidate the physiological mechanisms behind this observed gender difference.
