Association of Vitamin D with Uterine Fibroid in Women of Reproductive Age
Abstract
Objectives: To determine the mean change in fibroid size after vitamin D supplementation in Vitamin D deficient women visiting a tertiary care hospital of Lahore.
Methodology: This quasi-experimental trial study was conducted in department of Obstetrics and Gynecology, Sir Ganga Ram hospital, Lahore. from July 2022 to June 2023. A total of 115 premenopausal women between 40 and 45 years of age having fibroids of less than 5 cm by ultrasound were checked for vitamin D levels. The women having vitamin D levels less than 20ng/ml were included. Vitamin D 200,000IU oral supplementation, once weekly was given till the vitamin D level reached 50ng/ml or above or for 12 weeks’ duration whichever was earlier. After 12 and 24 weeks all women had an ultrasound and a difference in size and volume of the uterine fibroid was noted. Mean and standard deviation were calculated for numerical variables like Age, duration of symptoms, BMI and size of fibroid (pre, post and change). Post-stratifications, independent ‘t’ test was applied taking p ≤ 0.05 as statistically significant.
Results: The mean fibroid size at baseline and post-treatment was 34.23 ± 9.66 mm and 27.18 ± 9.39 mm respectively (p-value <0.0001). Mean change in fibroid size after vitamin D Supplementation in Vitamin D deficient women was 6.79 ± 1.98 mm.
Conclusion: This study concluded that Serum Vitamin D level inversely correlated with size of uterine fibroid and possibly supplementation of vitamin D reduces size of fibroid in vitamin deficient women.
