Marlene van LoggerenbergYour guide to Roux en Y gastric bypass procedure
Roux en Y gastric bypass is a transformative weight loss surgery that can help you make huge strides towards your health goals. In this procedure, we create a small pouch at the top of your stomach and connect it directly to your small intestine. This bypasses a large portion of your stomach and the first section of your small intestine, meaning you’ll eat less to feel full and absorb fewer calories.
Not only will you lose significant weight, but you’ll also see improvements in conditions like type 2 diabetes, high blood pressure, and sleep apnea.
How does it work? Gastric bypass surgery is performed laparoscopically, using small incisions in your abdomen. A laparoscopy, equipped with a light and camera, allows Dr Andrew Kiyingi to see your internal organs on screen. Through additional incisions, he carefully frees the stomach and creates a small pouch by stapling the upper part.
The small intestine is divided and reattached to this new pouch, bypassing a portion for reduced calorie absorption. A leak test ensures everything is secure before closing the incisions with dissolving sutures.

Frequently
Asked
Questions
How much does Roux en Y gastric bypass surgery cost?
There are 3 general categories available for funding gastric bypass:
- Private health insurance: Weight loss surgery, including gastric bypass, is typically covered by most private health funds under their top or gold plans. If you have a lower level of coverage, you’ll need to upgrade and complete any waiting periods. Private health insurance ensures access to private hospitals and covers most fees associated with your surgery.
- Self-funded: Some patients may opt to self-fund their gastric bypass surgery. Due to the complexity of gastric bypass surgery, though, this is generally not recommended. Dr Andrew Kiyingi will determine if this option is suitable for you based on your medical assessment.
- Superannuation funds: Some patients may use their superannuation to fund gastric bypass surgery. Keep in mind that if any unforeseen circumstances arise during surgery, you may have difficulty accessing private hospitals without insurance. Dr Andrew Kiyingi will assess if this option is suitable for you during your consultation.

How long does gastric bypass surgery take and how long is recovery?
The procedure will generally take 2-3 hours, depending on the individual case. Most people can return to normal activities within 2-3 weeks, with full recovery usually taking about 6 weeks.
Is a gastric bypass the same as a sleeve gastrectomy?
No, a gastric bypass and a sleeve gastrectomy are different procedures. A gastric bypass involves creating a small stomach pouch and rerouting the small intestine to this pouch, which reduces the amount of food you can eat and your calorie absorption. A sleeve gastrectomy involves removing a large portion of the stomach, leaving a sleeve-shaped stomach that is smaller and still connected to the digestive tract without rerouting.
What are the side effects of a Roux en Y surgical procedure?
The side effects of a Roux-en-Y gastric bypass can include:
- Nutritional deficiencies: Due to reduced absorption of nutrients, vitamin and mineral supplementation might be needed.
- Dumping Syndrome: Rapid emptying of stomach contents into the small intestine can cause nausea, vomiting, diarrhea, and dizziness.
- Surgical complications: Risks include infection, bleeding, and adverse reactions to anaesthesia.
- Bowel obstruction: A blockage in the intestines can occur post-surgery.
- Stomal stenosis: Narrowing of the connection between the stomach pouch and small intestine can cause difficulty swallowing and vomiting.
- Gallstones: Rapid weight loss can lead to gallstone formation.
It’s important to discuss these potential side effects with your surgeon to understand and manage the risks effectively.
What are the potential risks of a gastric bypass?
Like any surgery, there are potential risks.
- In the first 8 weeks of healing, there can be a 1% risk of major bleeding or leakage from the staple line.
- It is a more complex surgery to perform.
- There is a 5% risk of an internal hernia. This is a twisting of the bowel and can be serious, requiring further surgery.
- It is essential after bypass surgery to take their multivitamins as nutritional deficiencies can occur if this isn’t adhered to.
- In a few cases, people will suffer from diarrhoea, abdominal discomfort, and feeling unwell after eating foods with high sugar.
How can I prepare myself for surgery?
- Get a good night’s sleep before your surgery to reduce stress and aid your recovery. It’s all about rest and relaxation!
- Follow the fasting instructions from our bariatric anaesthetist–no food or drink (that includes chewing gum!)
- Follow medication guidelines, taking only those allowed with a sip of water.
- Plan your post-surgery needs. Arrange for someone to drive you home and help you during recovery. Prepare easy-to-east post-surgery foods that follow the diet guidelines.
