Examining how preoperative anemia affects recovery after bariatric surgery
The Impact of Preoperative Anemia on Postoperative Anemia and Related Nutrient Abnormalities After Bariatric Surgery
This study looks at how having anemia before weight loss surgery affects recovery and nutrient levels one year later for people who have had sleeve gastrectomy or gastric bypass.

What this trial studies
This observational study investigates the relationship between preoperative anemia and the occurrence of anemia and nutrient deficiencies one year following bariatric surgery. It focuses on patients who have undergone sleeve gastrectomy or Roux-en-Y gastric bypass and evaluates various nutrient levels, including ferritin, vitamin B12, folate, and transferrin saturation. The study aims to gather comprehensive follow-up data to understand the long-term effects of preoperative anemia on postoperative outcomes.
Who should consider this trial
Good fit: Ideal candidates are individuals aged 16 to 70 who have undergone bariatric surgery and have complete follow-up data.
Not a fit: Patients with baseline renal failure, those who are vegetarian, or those who experience significant postoperative bleeding may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could improve postoperative care and nutritional management for patients undergoing bariatric surgery.
How similar studies have performed: While the specific focus on preoperative anemia in bariatric surgery is less common, related studies have shown that managing anemia can positively impact surgical outcomes.
