Abstract
Background: To date, most predictors of effective weight loss (WL) after bariatric surgery (BS), except for blood glucose, do not consider laboratory tests, such as the amount of hemoglobin (Hb) before the procedure, as a method for assessing weight reduction. This study aimed to assess the Hb level before BS and its relationship to WL and to assess the relationship between pre- and postoperative Hb.
Methodology: A retrospective study was carried out from 2014 to 2020 at King Abdul-Aziz University Hospital (KAUH) in Saudi Arabia, Jeddah, Saudi Arabia, involving all patients who underwent BS in the study time frame in KAUH. Medical records of patients were reviewed, and data about patient’s age, gender, comorbidity, data of operation, comorbidities, and type of laparoscopic bariatric procedure were collected
Results: A significant positive correlation was found between preoperative Hb level and preoperative and postoperative weights at 3, 6, 9, and 12 months follow-up. A highly significant positive correlation was found between pre- and postoperative Hb levels. A significant positive correlation was found between post-operative Hb and pre-operative weight and postoperative weight at 6 and 12 months follow-up. A non-significant negative correlation was present between patients’ weight at 12 months follow-up and their age, gender, type of laparoscopic bariatric procedure, and comorbidity.
Conclusion: The study found a significant positive correlation between preoperative Hb level and preoperative and postoperative weights at 3, 6, 9, and 12 months follow-up. To explain the impact of Hb levels on postoperative WL among patients undergoing BS, future prospective large-scale cohort studies are much needed.
