Nutritional Health and Satisfaction After Bariatric Surgery: a Five-Year Retrospective Study

This study retrospectively examines 249 patients who underwent metabolic bariatric surgery at a specialized center between 2012 and 2017. It evaluates long-term outcomes including weight loss, excess weight loss percentage (%EWL), and nutritional deficiencies, with a specific focus on the effectiveness of targeted supplementation protocols to improve nutritional health post-surgery. The study analyzes different surgical procedures, including LSG, RYGB, and others, comparing primary and revision surgeries. Nutritional deficiencies in essential vitamins and minerals are assessed, highlighting the need for individualized supplementation based on the type of surgery and patient adherence.

Key objectives include:

• Assessing long-term weight loss and maintenance across different MBS procedures.
• Identifying the prevalence of nutritional deficiencies, particularly for iron, vitamin D, and B12.
• Evaluating patient satisfaction and quality of life improvements following MBS.

Data were collected from electronic clinical records and include anthropometric data, biochemical markers, and self-reported supplement use. Findings emphasize the importance of targeted supplementation and regular monitoring to address persistent deficiencies. The study contributes to understanding optimal long-term care strategies for MBS patients and underscores the importance of personalized nutritional support post-surgery.

Inclusion criteria
