What is Laparoscopic Roux-en-Y Gastric Bypass Surgery?

Laparoscopic Roux-en-Y gastric bypass (RYGB) is a weight loss surgery that works in two ways — by restricting how much food your stomach can hold and by reducing the amount of calories and nutrients your body absorbs. It is one of the most commonly performed and well-studied bariatric procedures in the world. During this surgery, the doctor:

• Creates a small stomach pouch (roughly the size of an egg) by dividing the upper portion of the stomach using surgical staples.
• Divides the small intestine and connects a section of it directly to the new small stomach pouch, bypassing the rest of the stomach and the upper part of the small intestine.
• Reconnects the bypassed section of the intestine lower down, so that digestive juices from the stomach and pancreas can still mix with food — just further along in the digestive tract.
• Performs all of these steps through small incisions using a laparoscope (a thin camera), avoiding the need for a large open cut.

The result is that you feel full much sooner after eating, consume fewer calories, and absorb fewer nutrients from food — all of which work together to produce significant, sustained weight loss.

Choosing to have weight loss surgery is a major and deeply personal decision. It is natural to feel a mix of hope, anxiety, and uncertainty. Your doctor and care team will guide you through every stage of the process, answer your questions honestly, and ensure you feel informed and supported every step of the way.

When would I need laparoscopic Roux-en-Y gastric bypass?

Your doctor may recommend RYGB if you are significantly overweight and have been unable to achieve lasting weight loss through non-surgical methods. It is particularly recommended when other health conditions related to obesity need to be addressed. This surgery is generally considered for:

• Adults with a body mass index (BMI) of 40 or above.
• Adults with a BMI of 35 or above who have one or more serious obesity-related health conditions such as type 2 diabetes, high blood pressure, obstructive sleep apnea, heart disease, or severe joint problems.
• Patients with poorly controlled type 2 diabetes, as RYGB has been shown to dramatically improve or even resolve this condition in many patients.
• Patients with significant acid reflux (GERD) for whom gastric bypass may offer superior symptom relief compared to other bariatric procedures.
• Patients who have not achieved adequate weight loss with a previously placed gastric band or sleeve gastrectomy.

What happens before the surgery?

If your doctor recommends RYGB, they will explain how it fits into your overall weight management plan. Gastric bypass surgery works best when supported by dietary changes, regular physical activity, and ongoing medical follow-up. Before proceeding, you will be assessed by a multidisciplinary team.

Before surgery, you will typically be asked to undergo:

• Comprehensive blood tests and a full health assessment to evaluate your fitness for surgery and anesthesia.
• Cardiac and respiratory evaluation if required, particularly if you have heart disease or sleep apnea.
• Nutritional counselling to prepare you for the significant dietary changes required after the surgery.
• A psychological evaluation to ensure you are emotionally prepared and have realistic expectations about the outcome.
• An upper gastrointestinal endoscopy to examine your stomach and oesophagus before surgery.
• A supervised pre-operative low-calorie or liquid diet, typically starting two weeks before surgery, to reduce liver size and improve surgical access and safety.

What do I need to do to get ready?

To prepare for surgery, your doctor might ask you to:

• Stop smoking at least four to six weeks before surgery, as smoking significantly increases the risk of complications including poor wound healing and blood clots.
• Avoid alcohol in the weeks leading up to the procedure.
• Stop taking certain medications such as blood thinners, non-steroidal anti-inflammatory drugs (NSAIDs), and some diabetes medications in the days before surgery as advised by your doctor.
• Follow the prescribed pre-operative liquid or very-low-calorie diet strictly as instructed.
• Stop eating and drinking for at least eight hours before the procedure.
• Begin taking prescribed vitamin and mineral supplements if advised before surgery, as nutritional deficiencies are common after gastric bypass.
• Arrange for someone to drive you home and support you with daily tasks during the first one to two weeks of recovery.

What happens during laparoscopic Roux-en-Y gastric bypass?

The surgery is performed under general anesthesia so you will be completely asleep and feel no pain. The steps of the procedure typically include:

1. The surgeon makes four to six small incisions in the abdomen.
2. A laparoscope and surgical instruments are inserted through the incisions. Carbon dioxide gas is introduced to gently inflate the abdomen and create space to work.
3. The upper portion of the stomach is divided using a surgical stapler, creating a small stomach pouch of about 15 to 30 millilitres in volume.
4. The small intestine is divided, and the lower portion is brought up and connected directly to the new stomach pouch. This is called the Roux limb.
5. The upper portion of the divided small intestine — carrying digestive juices from the stomach remnant, liver, and pancreas — is reconnected further down the Roux limb. This is called the jejunojejunal anastomosis.
6. All connections are tested for leaks before the instruments are removed and the small incisions are closed with stitches.

How long does the surgery take?

The operation typically takes one and a half to three hours. Most patients stay in hospital for two to three nights after surgery. Your doctor will give you a more specific estimate based on your individual health status and the complexity of your procedure.

What are the pros and cons of this surgery?

Laparoscopic RYGB is one of the most effective weight loss surgeries available. Patients typically lose 60 to 80 percent of their excess body weight over 12 to 18 months. Beyond weight loss, the surgery has powerful metabolic effects — type 2 diabetes improves or goes into remission in most patients, often before significant weight loss has even occurred. Blood pressure, cholesterol levels, sleep apnea, and joint pain also frequently improve.

However, as with any major surgery, there are important risks and long-term considerations to be aware of:

• Anastomotic leak: A rare but serious complication where one of the internal connections between the stomach and intestine leaks, requiring urgent treatment.
• Dumping syndrome: When food moves too quickly from the stomach pouch into the small intestine, causing symptoms such as nausea, sweating, dizziness, cramping, and diarrhoea shortly after eating sweet or fatty foods.
• Nutritional deficiencies: Because food bypasses part of the digestive tract, deficiencies in iron, calcium, vitamin B12, vitamin D, and folate are common without lifelong supplementation.
• Stricture: Scar tissue can form at the connection between the stomach pouch and intestine, causing narrowing and difficulty swallowing, which may require a procedure to stretch it open.
• Internal hernia: Gaps created in the rearranged bowel can allow loops of intestine to become trapped, which may require emergency surgery.
• Irreversibility: Unlike the gastric band, this surgery permanently alters the anatomy of the digestive system and is not easily reversed.
• Weight regain: Without sustained dietary discipline and lifestyle changes, some patients may regain weight over time.

What happens right after the surgery?

After surgery, you will be monitored closely in the recovery area and then transferred to a ward. The nursing team will manage your pain, check your wound sites, and encourage you to start moving and walking as soon as it is safe to do so — usually within the first day. You will begin with tiny sips of water and progress to clear fluids before being discharged. Before going home, the team will teach you about your wound care, medication routine, and the dietary schedule you must follow in the coming weeks.

When should I call my doctor?

You will have regular scheduled appointments, but you should contact your doctor immediately if you notice:

• Severe or worsening abdominal pain, particularly if it is sudden and intense.
• A fever above 38°C (100.4°F).
• Persistent vomiting or an inability to keep any fluids down.
• Redness, swelling, discharge, or increasing pain around any of the incision sites.
• Rapid heart rate, dizziness, or fainting, which may indicate internal bleeding or dumping syndrome.
• Difficulty swallowing or a sensation of food getting stuck.
• Signs of nutritional deficiency such as extreme fatigue, hair loss, numbness or tingling in the hands and feet, or difficulty concentrating.
• Shortness of breath, chest pain, or swelling and pain in the leg, which may indicate a blood clot.

The physical and emotional changes that follow gastric bypass surgery can be significant. If you are struggling with your body image, mood, relationship with food, or feel overwhelmed at any point, please reach out to your care team. Emotional and psychological support is a vital part of your long-term success, and help is always available.
