Procedures

Surgical procedures

Your surgeon considers your goals, dietary history, metabolic health and previous treatment when discussing procedure options.

Laparoscopic sleeve gastrectomy

A portion of the outer stomach is removed, leaving a narrow sleeve. Reduces hunger signals and improves satiety.

Roux-en-Y gastric bypass

The stomach is divided into a small pouch, bypassing the main stomach and the first portion of the small intestine. Often discussed for patients with reflux or type 2 diabetes.

One anastomosis gastric bypass

Similar to a gastric bypass, but with a single intestinal join rather than two. Offers meaningful weight and metabolic outcomes in selected patients.

Sleeve fundoplication

Combines sleeve gastrectomy with anti-reflux surgery. Suited to patients with obesity and significant reflux (GORD, gastro-oesophageal reflux disease).

Gastric bypass with calibration ring

A gastric bypass with a small ring to support long-term restriction. Most often considered after weight regain following a previous procedure.

Gastric band removal

Removal of an existing gastric band causing symptoms, discomfort or inadequate results. Can be combined with conversion to a different procedure.

Process

Assessment, surgery and follow-up

The first twelve months include structured recovery, dietary progression and metabolic review.

01

Surgical consultation

Your first appointment covers your medical history, weight history, eating patterns and goals. We discuss all relevant surgical and medical options together and provide a written plan.

02

Assessment and investigations

Our thorough assessment includes dietitian review, blood tests and body composition. Additional investigations such as gastroscopy or a sleep study may be arranged if needed, as well as physician review where required.

03

The Meridian Foundation Program

Once the decision to proceed is made, you complete our structured preparation phase covering health, nutrition, understanding and readiness, so you arrive at surgery prepared and with a clear plan for recovery.

04

Surgery and hospital stay

Surgery is performed laparoscopically at a connected private hospital. Most patients stay one to two nights. Structured recovery protocols help you return to normal activity as comfortably and quickly as possible.

05

Twelve months of structured follow-up

Scheduled follow-up across the first twelve months covers diet progression, clinical symptom monitoring, nutritional blood tests and supplement review.

06

Long-term metabolic care

Many patients continue with regular reviews beyond the first year. Ongoing care supports durable outcomes and gives you a team to return to as your needs change over time.
