Exploring Vitamin B12 Deficiency in Sleeve Gastrectomy from a Histological Study of a Cadaveric Stomach and Ileum.

J Diet Suppl

September 2017

Introduction: Vitamin B12 deficiency is more commonly found among patients who have undergone Roux-en-Y gastric bypass (RYGB) as compared to those with post-sleeve gastrectomies (SG). The major difference between SG and RYGB is that the latter greatly bypasses the stomach whereas the former simply reduces the gastric volume.

Purpose: The aim of this article was to study the stomach and the distal ileum histologically in a cadaver with SG to explain the higher rate of incidences of vitamin B12 deficiency seen in patients post-RYGB relative to patients post-SG.

Synopsis of recent research by authors named "Velma Rawlins"

  • - Velma Rawlins focuses on the impact of surgical weight loss procedures on nutrient deficiencies, specifically investigating the differences between sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB).
  • - Her research highlights the increased incidence of vitamin B12 deficiency in patients undergoing RYGB compared to those who have had SG, suggesting that the altered anatomy may contribute to this disparity.
  • - In her 2017 study published in the "Journal of Diet Supplements," she employs a histological approach to analyze the stomach and ileum of a cadaver with SG, providing insights into the underlying mechanisms of nutrient absorption issues post-surgery.
