A sleeve diet plan involves gradual dietary progression after surgery, focusing on protein-rich foods, minimal carbohydrates, and small portion sizes. Long-term, patients must continue eating nutrient-dense, low-calorie meals to maintain weight loss. Key components include lean meats, vegetables, whole grains, and avoiding sugary and fatty foods.

Patients typically need a Body Mass Index (BMI) of 35 or higher, with obesity-related health conditions, or a BMI of 40 or more to qualify for gastric sleeve surgery. This surgery, known as Vertical Sleeve Gastrectomy (VSG), involves removing about 80% of the stomach to reduce food intake and is one of the most popular bariatric procedures.

Gastric band surgery involves placing an adjustable band around the upper portion of the stomach, limiting food intake and promoting weight loss. This procedure is reversible and less invasive than other bariatric surgeries. It’s available privately and occasionally through the NHS for eligible patients.

The "Skinny Pen" refers to a weight-loss medication called liraglutide (brand name Saxenda) that is administered through a daily injection. It works by mimicking a hormone that regulates appetite, helping patients feel fuller for longer. This treatment is often used for individuals who struggle with obesity but are not candidates for surgery or who need additional help in managing their weight post-bariatric surgery. The drug is available by prescription and is used in conjunction with diet and exercise.

The choice between gastric sleeve surgery and gastric bypass depends on individual factors. The sleeve is less invasive and focuses solely on restricting stomach size, while the bypass alters both stomach size and digestive processes. Bypass surgery often results in more weight loss but comes with higher risks of malabsorption and complications.
