Scientists Discover Strange Link Between Vitamin D and Pain
Researchers at Fayoum University Hospital found that women with vitamin D deficiency (<30 nmol/L) experienced three times more moderate postoperative pain after breast‑cancer surgery and required significantly higher opioid doses. The deficient group used an average of 112 mg more tramadol in the first 24 hours, while intra‑operative fentanyl was modestly increased. The study suggests pre‑operative vitamin D supplementation could mitigate pain and opioid consumption, though its single‑center, observational design limits definitive conclusions.
