Achieve long-term weight loss with mini gastric bypass in Melbourne, a less invasive alternative to traditional bypass surgery. Dr Mo Atalla at BetterLife Surgery offers expert care, helping you regain control of your health with a procedure that supports sustainable weight loss.
Reduce Stomach Size & Bypass
Small Intestine With One Connection
Mini gastric bypass, also referred to as One-Anastomosis Gastric Bypass (OAGB), is a weight loss surgery that reduces stomach size and reroutes digestion with a single connection (anastomosis) between the stomach and small intestine. Unlike standard gastric bypass, which involves two anastomoses, mini gastric bypass is a simpler, less invasive procedure with a shorter operating time and recovery. By bypassing a section of the intestine, it limits food intake and absorption, supporting long-term weight loss.
Benefits of Mini Gastric Bypass:
- Single anastomosis, reducing surgical complexity and risk
- Shorter operating time compared to standard gastric bypass
- Lower risk of complications such as bowel obstructions and internal hernias
- Effective weight loss similar to traditional gastric bypass
- Reduced hunger due to hormonal changes after surgery
- Improved diabetes control, often leading to remission in type 2 diabetes
- Shorter hospital stay and quicker recovery time
How Does Mini Gastric
Bypass Promote Weight Loss?
Mini gastric bypass in Melbourne promotes weight loss by altering both the size of the stomach and the digestive process. First, the stomach is reduced to a small pouch, which limits the amount of food you can consume at once. This makes you feel full sooner and helps control overeating. The smaller stomach also produces fewer hunger hormones, leading to reduced appetite.
Additionally, the procedure bypasses a section of the small intestine, which limits the amount of calories and nutrients your body absorbs from food. Because less of the digestive tract is involved in breaking down food, fewer calories are absorbed, helping you lose weight. These combined effects—reduced food intake and fewer calories absorbed—result in weight loss.
How Much Weight Can I Lose With Mini Gastric Bypass?
The amount of weight you can lose with mini gastric bypass depends on several factors, including your starting weight, lifestyle, and adherence to post-surgery recommendations. On average, patients can expect to lose 60–70% of their excess weight within the first year. Dr Mo Atalla works closely with you to create a personalised plan, ensuring long-term success and helping you achieve your weight loss goals in a safe and sustainable way.

Life After Mini Gastric Bypass: What You Can Expect
After mini gastric bypass, you’ll experience significant changes in your eating habits and lifestyle. You’ll feel fuller faster due to your smaller stomach and may need to adjust to smaller, more frequent meals. As your body adjusts, it’s essential to follow a balanced diet and take vitamin supplements to prevent deficiencies. Regular follow-ups with Dr Mo Atalla and your dietitian will help ensure you stay on track.
Mini Gastric Bypass FAQs
Will I Need to Follow a Special Diet After Surgery?
Yes, after mini gastric bypass, you will need to follow a specific diet to ensure proper healing and long-term success. Initially, you’ll start with a liquid diet, and then progress to soft foods, and then solid foods over time. Your dietitian will guide you through the process, helping you make nutritious food choices that support your weight loss goals and prevent complications.
Can I Still Eat My Favourite Foods After Mini Gastric Bypass?
You can still enjoy your favourite foods in moderation, but your portion sizes will be much smaller due to the reduced stomach size. It’s essential to focus on nutrient-dense, healthy foods to prevent nutritional deficiencies and promote long-term weight loss. Your dietitian will help you adjust your eating habits to fit your new lifestyle.
How Soon Can I Return to Work After Mini Gastric Bypass?
Most patients return to work within 1–2 weeks after mini gastric bypass, depending on their recovery progress and the nature of their job. If your job is physically demanding, you may need a longer recovery. Dr Mo Atalla will advise you on the best time to resume activities.

As with any surgery, mini gastric bypass carries some risks, including infection, blood clots, and nutritional deficiencies.
