A retrospective study analyzing long-term outcomes of metabolic bariatric surgery (MBS) with a focus on weight loss, nutritional deficiencies, and patient satisfaction over a five-year follow-up. This study evaluates outcomes for different surgical procedures, including Laparoscopic Sleeve Gastrectomy (LSG), Roux-en-Y Gastric Bypass (RYGB), and other MBS techniques. The findings aim to provide insight into optimal nutritional management and patient care following bariatric surgery.

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:

1. Assessing long-term weight loss and maintenance across different MBS procedures.
2. Identifying the prevalence of nutritional deficiencies, particularly for iron, vitamin D, and B12.
3. 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: Patients aged 18 to 65 years who underwent metabolic bariatric surgery (MBS) at the Specialized Bariatric Center between 2012 and 2017, with a follow-up period of at least five years post-surgery.

Exclusion criteria: Individuals with a history of alcoholism, severe social anxiety impacting post-operative care participation, recent neoplastic disease diagnoses, neurocognitive disorders, or other systemic diseases potentially affecting quality of life and long-term outcomes.

Adults who underwent metabolic bariatric surgery, including LSG and RYGB, at a specialized center, with a focus on long-term outcomes in weight maintenance, nutritional health, and patient satisfaction
