Gastric Balloon

The gastric balloon is a soft, expandable non-surgical device that is temporarily inserted into the stomach. We understand that each person has different needs and requirements from their gastric balloon, that is why, unlike many other providers, we offer a range of gastric balloons for you to choose from.

Gastric Band

An adjustable band is placed around the upper part of the stomach, creating a small pouch above the band. When the gastric band is correctly adjusted it helps control appetite, slows eating and reduce portion size.

Gastric Bypass

The Gastric Bypass is the gold standard weight loss surgery. A small rectangular, pouch is formed from the upper stomach and joined to the small intestine. This surgery reduces calories absorbed and portion size.

Gastric Sleeve

Two thirds of the stomach is removed, leaving a smaller stomach in the shape of a sleeve. The portion of the stomach removed produces the hunger hormone, meaning there is a significant reduction in appetite.

Bariatric Rescue

Sometimes there might be reasons where further surgery or investigations need to take place post-surgery. There can be a number of reasons; maybe your original surgery is no longer working effectively or you are not happy with your weight loss. The best option might be to have bariatric rescue surgery.
