Is Sleeve Gastrectomy a Bariatric Surgery?

Is Sleeve Gastrectomy a Bariatric Surgery? Sleeve gastrectomy is a well-recognized bariatric surgery procedure that has gained popularity due to its high efficacy and low-risk profile. It is a surgical weight-loss procedure that involves removing a portion of the stomach, thereby reducing its size to about 15% of its original size. This reduction creates a sleeve or tubelike structure which significantly decreases the amount of food the stomach can hold, thereby aiding in weight loss.

While this procedure is primarily used as a treatment for obesity, it also has profound effects on various aspects of health. It has been shown to not only decrease body weight but also improve obesity-related conditions such as type 2 diabetes, high blood pressure, and sleep apnea. Bariatric surgery like sleeve gastrectomy is widely recognized as an effective long-term solution for weight management and overall improvement in health.

What is Sleeve Gastrectomy?

Sleeve gastrectomy, also known as vertical sleeve gastrectomy, is a type of bariatric surgery that aids in weight loss. It is a medical procedure specifically designed to help those struggling with severe obesity. The process involves the surgical removal of a large part of the stomach, leaving behind a smaller, sleeve-like portion that’s about the size and shape of a banana. This new stomach is significantly smaller than its original size, which limits the amount of food it can hold.

The primary purpose of the sleeve gastrectomy is to assist in weight loss for individuals suffering from obesity. Obesity is a serious medical condition where excess body fat has accumulated to an extent that it may have a negative impact on health. It’s associated with numerous health problems, including heart disease, diabetes, high blood pressure, and certain types of cancer. Treating obesity is therefore crucial for improving overall health and increasing lifespan.

The reduction in stomach size brought about by sleeve gastrectomy not only limits food intake but also impacts gut hormones or peptides that control hunger, satiety, and blood sugar. Post-surgery, patients often report reduced appetite and early satiety with smaller meals. Despite the reduced calorie intake after surgery, patients do not experience the extreme hunger or potentially malnourishing side effects that can occur with dieting. This makes sleeve gastrectomy an effective tool in the comprehensive treatment strategy for obesity.

How Does Sleeve Gastrectomy Aid in Weight Loss?

Sleeve gastrectomy aids in weight loss primarily through restriction, which is reducing the amount of food that can be consumed at one time. By removing a large part of the stomach and leaving a small, sleeve-like structure, the surgery significantly reduces the stomach’s capacity. Therefore, post-surgery, individuals can consume only a limited quantity of food, leading to fewer calories being ingested. This decrease in caloric intake is a key factor in promoting weight loss.

However, the benefits of sleeve gastrectomy extend beyond simple restriction. The procedure also influences various gut hormones responsible for hunger and satiety. For instance, it affects ghrelin, often referred to as the “hunger hormone.” The part of the stomach that produces most of this hormone is removed during surgery, leading to a notable reduction in hunger sensations post-surgery. Additionally, changes in gut hormones also improve conditions such as diabetes by enhancing the body’s response to ingested food.

Moreover, the smaller stomach size encourages healthier eating habits. Patients typically need to follow a strict diet after the operation, gradually progressing from liquids to pureed foods, then soft foods, and eventually regular foods. However, even when regular foods are reintroduced, portions need to be significantly smaller than before surgery. These dietary changes coupled with increased physical activity contribute towards maintaining long-term weight loss and overall health improvement following sleeve gastrectomy surgery.

Recovery and Long-Term Effects of Sleeve Gastrectomy

The recovery process after sleeve gastrectomy varies from person to person, but generally, hospital stay post surgery ranges from one to three days. Once discharged, the patient will need to follow a strict diet plan starting with liquids only, then gradually transitioning to solid foods over several weeks. During this period, it’s crucial to adhere to the guidelines provided by the healthcare team to aid in healing and promote weight loss.

Despite the invasive nature of the surgery, most patients report very little pain post-procedure due to advancements in surgical techniques. As with any major surgery, there may be potential complications such as infection, bleeding, or adverse reactions to anesthesia. However, these risks are relatively low and are further mitigated by carefully following post-operative instructions. Routine follow-ups with the surgical team play an essential role in monitoring recovery and ensuring any potential complications are identified and addressed promptly.

Long-term effects of sleeve gastrectomy extend beyond substantial weight loss. The alterations in gut hormones not only help reduce hunger but also have a positive impact on metabolic syndrome conditions such as diabetes, high cholesterol levels, and hypertension, often leading to their resolution or significant improvement. Furthermore, weight loss from sleeve gastrectomy has been linked with improved mobility, better sleep, reduced joint pain, and enhanced overall quality of life. It’s important to note that while sleeve gastrectomy can be a powerful tool for weight loss and health improvement, long-term success depends on committed lifestyle changes including healthy eating and regular physical activity.
