For people who struggle with obesity-related conditions, procedures leading to significant weight loss are a viable solution. Fortunately, there are a wide variety of options at your disposal. While some procedures are entirely non-surgical, others may involve more intervention. However, all of these procedures can lead to significant weight loss over time. Each procedure has its advantages and disadvantages. If you’re thinking about weight loss procedures, contact us at the NOSC to help you decide which option is right for you.
Here are the most common weight loss procedures in the UK.

What is a Gastric Band?

A gastric band is a small, inflatable band that fits around the top of your stomach, restricting your food intake. A 30-minute, life-transforming procedure, the gastric band is a safe and effective way to help you lose significant weight.

It’s a well-tolerated, minimally invasive procedure and has been implemented widely on patients around the world and in the UK for many years.

What is Gastric Bypass?

A gastric bypass procedure is designed to make you feel fuller while absorbing fewer calories from the food you consume. At NOSC, we offer two types of gastric bypass procedures, including the MGB (Single Anastomosis Gastric Bypass) and Roux-en-Y procedure.

MGB creates a small but long and narrow stomach that bypasses a small section of the small intestine. This helps you absorb less calories from the food you eat, making you feel fuller faster. This procedure is performed under general anaesthesia and can take between 60-90 minutes to complete.

On the other hand, the Roux-en-Y bypass procedure reduces the size of your upper stomach to about the size of an egg. Food bypasses the majority of your stomach and the upper part of your small intestine. In return, you absorb less fat and calories from the foods you eat.

What is Gastric Sleeve?

A gastric sleeve is a long-term surgical option for those who want to avoid an implanted device such as a balloon or band. This option combines the benefits of a gastric band and those of a gastric bypass.

A gastric sleeve procedure removes a portion of the stomach, reducing its size by around 80% (this varies from person to person). While the shape of the stomach is altered, it will continue to function normally. You’ll consume considerably less food over time courtesy of a small stomach and the elimination of Ghrelin, the hormone that stimulates appetite and hunger.

What is a Gastric Balloon?

A gastric balloon, or weight loss balloon, is a non-surgical weight loss alternative treatment for those who desire significant weight loss. It’s designed to induce weight loss by partially filling your stomach. This helps you feel less hungry and feel fuller faster. Effectively, the procedure changes your relationship with food. You’ll be expected to stick to a reasonable nutrition programme post-procedure. We’ll be there to help you every step of the way.
