A gastrectomy is the surgical removal of part or all of the stomach. It is often performed to treat stomach cancer, severe ulcers, or obesity. A partial gastrectomy removes only a portion, while a total gastrectomy removes the entire stomach, requiring significant lifestyle changes post-surgery.

Similar to a GI doctor, a "gastro dr" refers to a specialist in gastroenterology. Patients typically see these specialists for issues related to digestive health, such as ulcers, acid reflux, or liver disease. They perform diagnostic procedures like endoscopies or colonoscopies to identify and treat conditions. For bariatric surgery patients, gastroenterologists can help manage complications that arise from surgeries like the Roux-en-Y or gastric band.

Sleeve banding combines two bariatric procedures: the gastric sleeve and an adjustable gastric band. It is a less common technique used to enhance the weight-loss results of the sleeve by adding additional restriction through the band. However, complications from the band have made it less favorable in recent years.

Gastric bypass surgery involves creating a small pouch from the stomach and connecting it directly to the small intestine. It significantly reduces food intake and alters digestion, leading to substantial weight loss. This procedure is one of the most common forms of bariatric surgery and is highly effective for long-term weight reduction.

The Allurion Balloon is not yet widely available on the NHS, though some private clinics in the UK offer it. This non-invasive procedure is an attractive option for individuals seeking a temporary weight-loss solution without the risks associated with surgery.
