Understanding Different Types of Bariatric Surgery in Ireland

Bariatric Surgery Procedures

Bariatric surgery has emerged as a transformative solution for individuals struggling with severe obesity and related health conditions. In Ireland, there are several types of bariatric surgery available, each tailored to meet different needs and medical conditions. Here’s an in-depth look at the various bariatric surgery options offered at Blackrock WeightCare, guided by the expertise of Dr. William Robb.

Gastric Bypass Surgery

What is Gastric Bypass Surgery?

Gastric bypass, also known as Roux-en-Y gastric bypass, is a procedure that involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine. This reduces significantly the capacity of the stomach and bypasses a segment of the small intestine resulting in reduced absorption.


Gastric bypass surgery leads to significant weight loss, with patients typically losing 60-80% of their excess weight. This procedure also helps in resolving or improving conditions such as type 2 diabetes, hypertension, and sleep apnea. One of the major advantages of gastric bypass is its long-term success in maintaining weight loss. By altering the digestive tract, this surgery changes how the body absorbs nutrients, leading to sustained weight loss over the years.

Sleeve Gastrectomy

What is Sleeve Gastrectomy?

Sleeve gastrectomy involves removing approximately 75-80% of the stomach, resulting in a tube-like or “sleeve” structure. This significantly reduces the stomach’s capacity and helps in weight loss. Patients also benefit as the removed portion of the stomach is in part responsible for the production of hormones that drive hunger and cravings.


Patients undergoing sleeve gastrectomy typically lose 50-70% of their excess weight. It also retains the natural function of the stomach without altering the digestive tract significantly, which can be beneficial for long-term nutritional health. Many patients like its relative simplicity and the fact that there is less rearrangement of the  gastrointestinal tract. 

SADI-S (Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy)

What is SADI-S?

The SADI-S procedure combines aspects of sleeve gastrectomy and intestinal bypass. It involves performing a sleeve gastrectomy followed by bypassing a portion of the small intestine.


The SADI-S procedure offers substantial weight loss, comparable to gastric bypass, and is particularly effective in improving or resolving type 2 diabetes. By combining two weight loss mechanisms—restricting food intake and altering nutrient absorption—this procedure provides significant metabolic benefits. Patients undergoing SADI-S can expect profound changes in their overall health and quality of life due to the comprehensive approach to weight loss and metabolic improvement.
