The Importance of Nutrition in Bariatric Surgery
Nutrition after bariatric surgery (such as gastric sleeve, gastric bypass, etc.) directly affects the success of the operation and weight management. A diet tailored to your new stomach structure should:
- Ensure adequate protein intake
- Prevent vitamin/mineral deficiencies
- Be planned in a way that doesn’t strain the stomach
- Include a gradual transition to solid foods
Post-Surgery Considerations
1. Fluid Intake
- Drink 1.5–2 liters of water daily
- Consume fluids 30 minutes before or after meals
- Sip slowly and steadily
2. Protein Priority
- Aim for 60–80 grams of protein per day
- Choose high-quality sources like eggs, fish, chicken, and yogurt
- Protein powders may be used with doctor and dietitian approval
3. Nutritional Supplements
- Multivitamins (especially B12, vitamin D, iron)
- Calcium supplements
- Omega-3 support
4. Eating Technique
- Chew each bite 20–30 times
- Eat small portions over 20–30 minutes
- Avoid distractions like TV or phones during meals
