All operations carry risk. Your individual risk depends on the procedure, your health, your surgeon’s experience and the hospital where surgery is performed. Understanding the possibilities helps you recognise why an experienced team and long-term follow-up are important.

Eating after weight-loss surgery
Your bariatric dietitian and surgical team will guide you from fluids through puréed and soft foods to a broader long-term eating pattern. Common habits include:
→ Prioritising protein at meals
→ Eating small portions slowly and chewing thoroughly
→ Stopping when comfortably satisfied
→ Separating fluids from meals as directed
→ Staying hydrated between meals
→ Choosing foods that support nutrition and make your body feel well
Momentum Health focuses on sustainable habits rather than labelling individual foods as simply “good” or “bad”. Your overall pattern matters more than one food or one meal.
Ongoing bariatric follow-up
→ Appointments with your surgeon and bariatric team
→ Regular blood tests and medication reviews
→ Nutrition counselling
→ Support with movement and physical activity
→ Psychological or behavioural support when helpful
→ Patient education sessions or peer support
