Common VSG side effects include nausea, vomiting, acid reflux, and constipation due to the smaller stomach size. Nutrient deficiencies, like vitamin B12 and iron, may occur if patients don't follow their prescribed supplements. Long-term complications can include weight regain or the development of gastroesophageal reflux disease (GERD).

Endoscopic Sleeve Gastroplasty (ESG) is a non-surgical weight-loss procedure where a gastroenterologist uses an endoscope to stitch the stomach into a smaller size, reducing its capacity. Unlike traditional bariatric surgery, ESG is performed through the mouth and doesn’t involve cutting or removing any part of the stomach. Recovery is quicker, and the procedure is reversible, but the weight loss achieved is typically less significant than with RNY or gastric sleeve surgery.

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.

Slimming tablets, also known as weight-loss pills, come in various forms, including prescription medications like Orlistat and Phentermine, and over-the-counter supplements. While these pills may aid in weight loss, they should be used with caution, as they can have side effects and should be paired with healthy diet and exercise.

A total gastrectomy is a surgical procedure where the entire stomach is removed, usually due to stomach cancer or severe damage. The esophagus is then directly connected to the small intestine. This life-altering surgery requires patients to follow strict dietary guidelines, including smaller, more frequent meals, and take supplements to ensure proper nutrition.
