Before undergoing bariatric surgery like RNY, patients are required to follow a pre-op diet to reduce liver size and fat around the stomach. This makes the surgery safer and easier for the surgeon to perform. The pre-op diet typically consists of high-protein, low-carbohydrate shakes, and liquids for 1-2 weeks before surgery. It’s an important step in preparing the body for surgery and ensuring optimal recovery post-op.

The term bariatric refers to the branch of medicine focused on the prevention and treatment of obesity and related disorders. Bariatric procedures, such as gastric bypass or sleeve gastrectomy, are designed to help patients achieve significant, long-term weight loss when other methods like diet and exercise have failed.

In the UK, gastric sleeve surgery is available through the National Health Service (NHS) for patients who meet specific criteria, such as having a Body Mass Index (BMI) over 40 or over 35 with obesity-related health conditions. Private options are also available, and the cost typically ranges from £8,000 to £12,000.

Although individual weight loss will fluctuate depending on factors like health, age, starting weight, and weight loss commitment, patients can expect to lose anywhere from five to 15 pounds per week for the first few months. At around the six-month mark, the weight loss will slow to one to two pounds per week.

In medical terms, GI stands for Gastrointestinal, referring to the digestive system, which includes the stomach, intestines, and other associated organs. GI disorders encompass a wide range of conditions that affect digestion, including gastritis, irritable bowel syndrome (IBS), and gastrointestinal cancers.
