What supplements will I need after bariatric surgery?
Your care team should specify your supplements and doses based on your operation and blood tests. Ask about a multivitamin, calcium, vitamin D, vitamin B12 and iron, and how to space doses. Do not assume one product or serving size meets all of your needs.
- Bring your supplement labels to follow-up visits.
- Ask when blood tests are due and who will review them.
- Tell your team if you cannot tolerate your supplements.
- Discuss any proposed change in formulation with your clinician.
How should I progress my diet after surgery?
Follow the written food and fluid plan from your surgical team. Programs may progress from liquids to pureed, soft and regular textures, but timing and targets are individualized. Do not advance a stage simply because a generic online timeline says to do so.
Choosing products with your care team
Ask your dietitian about suitable multivitamins, protein supplements and calcium products. Compare the actual label with your prescribed plan. Product advertising does not establish effectiveness or suitability for your procedure.
Where can I find more information?
The NIDDK guide to weight-loss surgery explains surgery types, benefits and risks. Use it to prepare questions for your care team.
