For individuals struggling with obesity, gastric band surgery provides a minimally invasive, adjustable, and reversible weight loss solution. By placing a silicone band around the upper stomach, the procedure helps control portion sizes, making patients feel full with smaller amounts of food. Unlike other bariatric surgeries, the band can be tightened, loosened, or removed, allowing for customised weight loss management over time.

Why Consider Gastric Band Surgery?

Here are some of the main reasons as to why you should consider Gastric Band Surgery in Melbourne: 

• Minimally Invasive – Performed laparoscopically with small incisions for quicker recovery.

• Adjustable & Reversible – The band can be modified or removed if necessary.

• Gradual, Controlled Weight Loss – Encourages healthy, sustainable weight reduction.

• No Permanent Stomach Alteration – Unlike gastric bypass or sleeve gastrectomy, the digestive system remains intact.

With over 14 years of surgical expertise, Dr. Niruben Rajasagaram, a leading bariatric and upper gastrointestinal surgeon in Melbourne, specialises in advanced laparoscopic weight loss procedures, including gastric banding. This blog will explore what gastric band surgery is, who qualifies for it, and what to expect from the procedure.

Who is a Candidate for Gastric Band Surgery?

Not everyone qualifies for gastric band surgery. Ideal candidates typically include:

• Individuals with a BMI of 30 or higher (especially those with obesity-related health conditions such as diabetes or hypertension). You can check your BMI score here. 

• Patients who have struggled with long-term weight loss despite diet and exercise efforts.

• Those committed to making permanent lifestyle changes, including diet modifications and regular physical activity.

• Individuals seeking a non-permanent, adjustable weight loss solution compared to other bariatric procedures.

However, surgery is not recommended for individuals who:

❌ Have an uncontrolled psychiatric condition.

❌ Struggle with drug or alcohol use.

❌ Are unable to understand the risks, benefits, and necessary lifestyle changes.

Before recommending surgery, Dr. Niruben Rajasagaram conducts a thorough evaluation to ensure that the gastric band is the right choice for each patient’s unique needs.

Benefits and Risks of Gastric Band Surgery

Benefits

✔ Effective Weight Loss – Can help individuals lose 40–60% of excess weight, depending on their commitment to lifestyle changes.

✔ Minimally Invasive – Faster recovery with lower risk of infections and hernias.

✔ Health Improvements – Reduces the risk of diabetes, high blood pressure, and urinary incontinence.

✔ No Nutrient Malabsorption – Unlike other bariatric surgeries, the body continues to absorb nutrients normally.

✔ Adjustable & Reversible – The band can be tightened, loosened, or removed based on weight loss progress or medical needs.

✔ Better Quality of Life – Many patients report improved mobility, confidence, and overall well-being.

Risks

❌ Slower Weight Loss – Results may take longer than other bariatric procedures.

❌ Possible Complications – The band can slip, erode, or malfunction, sometimes requiring follow-up surgery (15–60% of cases).

❌ Surgical Risks – As with any surgery, there’s a risk of infection, bleeding, blood clots, or anesthesia-related issues.

❌ Digestive Issues – Some patients experience vomiting, acid reflux, stomach ulcers, or oesophagal dilation if dietary guidelines aren’t followed.

❌ Scar Tissue Formation – Can lead to bowel blockages in rare cases.

While gastric band surgery can boost confidence and improve health, it requires a commitment to diet and lifestyle changes for lasting success. Those expecting instant weight loss may be disappointed, as progress is gradual and varies from person to person.

What to Expect After Gastric Band Surgery?

At the Hospital

• You'll rest until the anaesthesia wears off and may need pain relief.

• A drip in your hand or arm will provide fluids.

• You'll be encouraged to move around as soon as possible.

• Doctors will give you wound care instructions and allow you to drink fluids once you're ready.

Going Home

• Most patients go home the same day or the next day after surgery.

• The hospital team will ensure you can move around and eat before discharge.

• Arrange for someone to drive you home and stay with you for a day while the anaesthesia fully wears off.

• Over-the-counter painkillers can help manage discomfort.

• Follow-up appointments will include:

• ✔ Band adjustments if needed.

• ✔ Weight loss progress checks.

• ✔ Blood tests for nutrient and liver function monitoring.

Eating After Surgery

• A dietitian will guide you on dietary changes.

• You'll need to gradually increase food intake to help healing.

• Take multivitamins and minerals to maintain proper nutrition.

• Avoid high-calorie drinks like sugary sodas, as they can pass through the band and cause weight gain.

Complications of Gastric Band Surgery

Like any surgery, gastric band surgery has some risks, including:

• Reaction to anesthesia

• Excessive bleeding

• Blood clots (DVT)
  

Other possible complications include:

• Infection – Redness or soreness around the wound.

• Injury to nearby organs – Such as the stomach or oesophagus.

• Band issues – Slipping, leaking, or deflating.

• Band erosion – The band gradually moves through the stomach wall (affects about 3–4% of patients).

• Gallstones – Can develop if you lose weight too quickly.

When to Contact a Doctor?

Seek medical help if you experience:

✔ High fever

✔ Difficulty swallowing

✔ Severe stomach or chest pain

✔ Breathing problems

✔ Excessive vomiting

Can a Gastric Band Be Removed?

Yes, the band can be removed through keyhole surgery if complications arise or if you're unhappy with the results. However, removing the band may lead to weight gain unless you opt for another weight-loss procedure.

Other Possible Effects

• Weight regain – Some may not lose as much weight as expected or may regain it later.

• Excess skin folds – This can cause irritation or infection; cosmetic surgery (like a tummy tuck) may be an option after at least a year.

Pregnancy After Gastric Band Surgery

You can get pregnant after surgery, but it's best to wait until your weight stabilises. During pregnancy, a doctor will:

• Monitor weight gain.

• Ensure proper nutrition.

• Adjust or deflate the band if needed, especially in cases of severe morning sickness.

If you're planning a pregnancy, consult your doctor for guidance.

Taking the First Step Towards Lasting Weight Loss!

Gastric band surgery is a safe and adjustable option for weight loss, but it requires a commitment to lifestyle changes and regular follow-ups. If you're considering surgery, Dr. Niruben Rajasagaram offers expert guidance to help you choose the best approach for your needs.

Other effective weight loss surgeries include:

• Gastric Bypass – Promotes significant weight loss by reducing stomach size and altering digestion.

• Sleeve Gastrectomy – Removes a portion of the stomach to limit food intake.
