Frequently Asked Questions
How much protein after bariatric surgery?
Most bariatric patients need 60-80g protein daily minimum, sometimes up to 100g. Protein prevents muscle loss and supports healing.
What vitamins are needed after bariatric surgery?
Lifelong supplements required: bariatric multivitamin, calcium citrate (1200-1500mg), vitamin D (3000 IU), B12, and iron for menstruating women.
What are the diet stages after surgery?
Stage 1: Clear liquids. Stage 2: Full liquids. Stage 3: Pureed foods. Stage 4: Soft foods. Stage 5: Regular foods. Each stage is 1-4 weeks.
Why can I not drink with meals?
Drinking with meals fills your small stomach with liquid, reduces protein intake, and can flush food through too quickly causing dumping syndrome.
