Micronutrients & recovery
Bariatric surgery procedures (SG, RYGB, BPD/DS) significantly increase the risk of micronutrient deficiencies due to reduced oral intake and malabsorption, necessitating lifelong biochemical monitoring and targeted supplementation.
If you undergo bariatric surgery, you must commit to lifelong blood tests and vitamin/mineral supplementation. This is not optional; surgery changes how your body absorbs nutrients, leading to dangerous deficiencies if not managed. Work with your bariatric team to establish a monitoring schedule (typically every 3-12 months initially, then annually) and adhere strictly to prescribed supplements.
The incidence of these may increase after bariatric surgery as all procedures potentially cause clinically significant micronutrient deficiencies. Therefore, preparation for surgery and long-term nutritional monitoring and follow-up are essential components of bariatric surgical care.
