Bariatric Nutrition
Specialised nutrition support before and after bariatric surgery — tailored to optimise recovery, prevent deficiencies, and support long-term success.
Why Bariatric Nutrition Matters?
Nutrition plays a vital role at every stage of bariatric surgery — supporting a smooth recovery, preventing complications, and promoting lifelong health.
Nutrient Deficencies
Up to 80% of patients experience at least one micronutrient deficiency after bariatric surgery without proper nutrition support.
Protein Needs
Adequate protein is essential to prevent muscle loss and support healing, yet many patients struggle to meet requirements post-surgery.
Weight Regain Risks
Studies show that without ongoing dietary guidance, up to 50% of patients may experience significant weight regain within 5 years.
Long-Term Wellness
Vitamin and mineral deficiencies can lead to anaemia, osteoporosis, and other preventable complications if not managed correctly.
Who we help?
Our bariatric dietitians support people who are:
- Preparing for bariatric surgery and needing pre-surgery protocols (e.g., Optifast).
- Recently undergone gastric bypass, sleeve gastrectomy, lap band, or other bariatric procedures.
- Adjusting to the stages of eating post-surgery (liquid → puree → soft → regular).
- Needing long-term support with portion control, meal planning, and supplement use.
- Managing challenges such as nausea, reflux, dumping syndrome, or food intolerances.
- Wanting to maintain weight loss while preventing nutrient deficiencies.
Common Bariatric Surgeries
Alongside your surgeon’s care, our dietitians support clients after all major bariatric procedures, including:
- Gastric Bypass – A small stomach pouch and rerouted intestine reduce food intake and absorption.
Sleeve Gastrectomy (Gastric Sleeve) – Part of the stomach is removed, leaving a smaller, tube-shaped stomach.
Adjustable Gastric Banding (Lap Band) – A band creates a small pouch at the top of the stomach to limit food intake.
Gastric Balloon – A balloon inflated in the stomach takes up space to reduce hunger.
Duodenal Switch / BPD – Removes part of the stomach and bypasses intestines for significant weight loss.
Mini Gastric Bypass – A simplified version of gastric bypass with similar results.

How We Work With You
Our bariatric dietitians provide support that is practical, compassionate, and tailored to your journey.
We start by reviewing your medical history, type of surgery, current eating patterns, and blood test results. This helps us identify your specific nutritional needs and set achievable goals.
You’ll receive a tailored plan with portion sizes, meal ideas, supplement guidance, and practical tips for each stage of recovery. We make sure it’s realistic and fits into your lifestyle.
Regular follow-ups give us the chance to track your progress, adjust your plan as your needs change, and keep you motivated. We also monitor blood results to prevent deficiencies and maintain long-term health.
