“Phases” are slowly progressed through for ~8-12 weeks after surgery

Diet for life is a low fat, sugar free, balanced diet with smaller serving sizes

CHEW WELL- otherwise, will lead to N/V

Dumping Syndrome with high fat and/or high sugar foods after Gastric Bypass (and mild dumping is possible after sleeve gastrectomy)

Post-Op Diet

Separate foods/fluids by at least 30 minutes

Fluid goals: 6-8 cups/day, SF, non-carbonated, caffeine free, non-caloric

Avoid Alcohol- ESPECIALLY GBP patients

8) Post-Op Supplements/Lab Monitoring

Sleeve Gastrectomy/Gastric Banding MVI/Mineral Supplement daily Calcium Citrate- 1200-1500 mg/day

Gastric Bypass MVI/Mineral Supplement daily Vitamin B12- 500 mcg/day sublingual or

1000mcg IM injection/month Calcium Citrate- 1200-1500 mg/day Iron (for menstruating women or if directed by

MD or FNP)- 200-325 mg of Ferrous Sulfate daily

CMP (electrolytes, albumin, etc.) CBC Serum B12 (especially with GBP) Ferritin/Iron Profile Lipid Panel 25-hydroxyvitamin D or ionized

Calcium

Is an absolute MUST!!!

Patients should gradually work up to goal of 45 minutes- 1 hour of exercise most days of the week.
