Post-Bariatric Malabsorption and Lifelong Multivitamins

• Severe Anatomical Changes: Bariatric surgeries such as Roux-en-Y gastric bypass and biliopancreatic diversion significantly alter the normal digestive pathway.
• Permanent Reduction in Absorption Surface: These procedures bypass major portions of the stomach, duodenum, and upper jejunum, which are critical sites for the enzymatic breakdown and uptake of essential micronutrients.
• Lifelong Nutritional Vulnerability: Because the physiological changes are permanent, the risk of developing deficiencies in vitamins A, D, E, K, B-complex (especially B12 and folate), and essential minerals like iron, calcium, zinc, and copper persists for the rest of the patient's life.
• Prevention of Complications: Daily, lifelong supplementation with comprehensive multivitamins and targeted minerals is clinically necessary to prevent severe neurological, hematological, and metabolic disorders associated with long-term malabsorption.
