What is Sleeve Gastrectomy?
Sleeve gastrectomy is a type of bariatric surgery that helps individuals with obesity achieve significant weight loss. This irreversible procedure is typically considered only when other weight-loss methods have not produced satisfactory results.
In simple terms, sleeve gastrectomy reduces the size of the stomach by vertically removing a portion of it. This smaller stomach size offers several advantages on the path to weight loss, primarily by allowing patients to feel full more quickly. With less room in the stomach, patients can feel satisfied with smaller portions, leading to a decrease in food absorption by the body.
Additionally, patients often experience a reduction in hunger, as the procedure removes the part of the stomach that produces ghrelin, the hormone responsible for appetite regulation.
How to Prepare for Sleeve Gastrectomy
To ensure the best results, it’s important to follow specific steps and pre-surgery instructions. Below are the key preparation guidelines for patients considering sleeve gastrectomy.
1. Preliminary Medical Assessments
The first step in preparing for bariatric surgery is undergoing a series of preliminary medical evaluations. Patients must consult with a bariatric surgeon who will assess their unique situation and conduct tests to determine if sleeve gastrectomy is suitable for them. This assessment helps identify any potential risks and provides a tailored plan for the patient.
These preliminary tests are critical, as each patient is unique, and this approach allows the surgeon to offer specific guidance for achieving the best possible outcome.
2. Follow a Tailored Diet
Pre-surgery instructions often include adopting a tailored diet and physical activity. These steps help patients adjust to the lifestyle changes they will need after surgery and may also assist in losing some weight before the procedure. This pre-operative weight loss can reduce the size of the liver and make the surgery easier.
- High-Protein Diet: A high-protein diet is typically recommended, focusing on lean meats, fish, and cheese. Staying hydrated and consuming fruits and vegetables for their vitamins is crucial. A multivitamin supplement may also be beneficial.
3. Follow Surgeon’s Instructions
While general guidelines apply to most patients, each case is unique. Patients should always follow the final preparation instructions from their surgeon. For example, patients are often advised to quit smoking and reduce alcohol intake before surgery:
- Quit Smoking: Smoking can increase the risk of complications during and after surgery, such as infections and respiratory issues.
- Limit Alcohol: Alcohol can raise the risk of bleeding and infections, so it is recommended to avoid it in the weeks leading up to surgery.
Preparing for Sleeve Gastrectomy is an essential part of achieving successful weight loss through bariatric surgery. By following the right pre-operative steps, patients can ensure a smooth surgery and a better post-operative experience.
