Lifelong, structured multidisciplinary follow-up including nutritional supplementation is mandatory after bariatric surgery to prevent deficiencies and manage comorbidities.
You must commit to lifelong medical and nutritional follow-up. This includes regular blood tests and taking prescribed supplements to prevent deficiencies. Skipping follow-up risks serious health complications, even if you feel well.
