What is Gastric Sleeve?

Gastric sleeve is a surgical procedure that results in significant weight loss. A large portion of the stomach is removed, creating a smaller stomach pouch. This reduces the quantity of food you are able to consume and produces a feeling of “fullness” after eating far less. The procedure creates a stomach about the size of a banana, called a “sleeve.” This newly-shaped stomach is about one tenth the size of your original stomach. The section of the stomach removed is the area that produces the hormone that increases appetite. This procedure is appropriate for those with a BMI over 40.

Gastric Sleeve surgery is one of the most popular and successful weight loss options available when it comes to bariatric surgery. The Gastric Sleeve procedure is sometimes called the Vertical Sleeve Gastrectomy or Sleeve Gastrectomy Surgery. Each name refers to the same procedure.

Gastric Sleeve procedures can assist patients in dropping a significant amount of weight and avoiding the health risks associated with obesity, such as type 2 diabetes, hypertension, sleep apnea, and heart disease.

For those who have been unable to lose weight by diet or exercise alone, Gastric Sleeve surgery is a long-term method to shed pounds and maintain a healthy weight and lifestyle. Additionally, most PPO insurance plans accommodate these procedures.

At West Medical, we provide gastric sleeve surgery in Los Angeles, Orange County and surrounding areas, and we're dedicated to guiding you through the entirety of the treatment process. Below, you'll find some valuable information that may address some of your questions about the Gastric Sleeve.

How Gastric Sleeve Surgery Works

The Gastric Sleeve procedure changes the stomach into a sleeve-like shape, decreasing its size by nearly 85%, curbing your hunger and assisting in healthy, gradual weight loss.

Gastric Sleeve surgery involves making small incisions in the abdominal area, and portioning off a large section of the stomach with staples, in effect removing it from the digestive system. The procedure has been a great alternative to more major weight loss surgeries, such as gastric bypass surgery or duodenal switch surgery. A sleeve gastrectomy surgery can be performed laparoscopically (which involves making small incisions like those made during the LAP-BAND and Realize Band procedure), and it's usually less complicated than other bariatric procedures.

Sleeve Gastrectomy Incisions

When our Orange County and Los Angeles gastric sleeve surgeons reduce the size of your stomach, this allows you to become full more quickly and in turn reduces appetite. Gastric Sleeve surgery is used along with a healthy diet—this means choosing the right foods and portions, along with supplementing your meals with vitamins, since your overall intake will be reduced. Additionally, the portion of your stomach that is removed produces a hormone called ghrelin. This hormone is responsible for making you feel hungry. After surgery, a smaller amount of this hormone is in the body. Patients often report feeling less hungry after their operation.

Benefits Of Gastric Sleeve Surgery

Gastric Sleeve surgery is a largely successful method for weight loss. A sleeve gastrectomy surgery not only assists our Los Angeles and OC patients with losing weight, but is also an essential component in maintaining a healthy weight in the long-term.

Gastric Sleeve surgery is a great alternative to more major weight loss surgeries, such as Gastric Bypass surgery or Duodenal Switch surgery, and can be performed laparoscopically, involving small incisions much like those made during the LAP-BAND and Realize Band procedures.

Unlike other surgical approaches to weight loss, Gastric Sleeve procedures can have a quicker recovery time, involve fewer risks, and typically don’t have to be adjusted over time. Gastric Sleeve procedures may vary in intricacy, but most can be completed using minimally invasive techniques that reduce post-operative pain and scarring, and allow for a quicker recovery time.

At West Medical, we prioritize your safety, comfort, and health. Your Los Angeles or Orange County gastric sleeve surgeon will explain your options clearly so you can make an informed, empowered decision if you think the sleeve is a good choice.

Gastric Sleeve Surgery Results

With the assistance of continued exercise and healthy eating, many patients who have undergone a Gastric Sleeve lose more than half of their excess weight and are able to keep it off. At West Medical we are not focused on just the weight loss results from the bariatric surgery, but also improvements in quality of life, reduction or remission of weight-related diseases, and longer life. Many patients report improvements in health conditions related to obesity, after bariatric surgery.

According to the American Society for Metabolic and Bariatric Surgery (ASMBS), bariatric surgery often results in significant weight loss and improvement of negative health conditions. They say a “large population study comparing mortality rates of bariatric and non-bariatric patients found a greater than 90 percent reduction in death associated with diabetes and a greater than 50 percent reduction in death from heart disease.”

Gastric Sleeve Risks

Like with all surgical procedures, some risks may be associated with Gastric Sleeve procedures. These risks include:

  • Acid leakage can occur along the stapling line, which may require a follow-up operation or the use of a tube for fluid draining.
  • Particular foods may cause nausea, discomfort and vomiting.
  • Risk of vitamin or nutrient deficiency. This is why it’s important to come to follow up visits and take advantage of the comprehensive after-surgery support that our team offers.

When you meet with a surgeon at West Medical, whether in our Los Angeles or Orange County office, or one of are many other offices, he or she will explain the risks and benefits of the procedure in detail. When you make a decision about your health, you are taking an important step. That step should be taken with all the education needed to feel as though you’re in control of your journey. We are here to guide and support you every step of the way.

FAQs About Gastric Sleeve

What is the pre-op diet like for gastric sleeve surgery?

Your pre-op diet begins about two weeks prior to surgery. A low-calorie, low-fat diet, with very limited carbohydrates, eating only lean proteins, veggies, and low-calorie, non-sugar liquids are allowed. Two days prior to your surgical appointment, you must switch to a diet of clear liquids along with one sugar-free protein shake each day. No caffeinated or carbonated beverages should be consumed, although you can drink decaf tea or coffee, water, or broth. These actions will shrink the fat surrounding your liver, making the surgery safer and easier to perform.

What is the post-op diet like for gastric sleeve?

The post-op diet involves only clear liquids during the first phase. Only sugar-free, clear liquids are safe, and will help you avoid unpleasant symptoms. No caffeinated or carbonated liquids should be consumed. The second week after surgery involves protein shakes, thin broths and soups, with no chunks, sugar-free pudding, yogurt, diluted, pulp-free juices and thinned hot cereals. At week three you move onto baby food, soft scrambled eggs, soup, cottage cheese, canned fruit and other bland, easy to digest foods.

Will I have excess loose skin after the procedure? What are my options?

After losing a great quantity of weight, it is not uncommon to be left with an excess of skin. Each person is different in the quantity of excess skin and tissue that remains. To remove it and have a slimmer, fit look may involve a tummy tuck, breast lift, or body lift. Body contouring procedures are customized to address the individual patient at West Medical, but often include removing excess skin, tissue, and residual fat on the lower abdomen. This procedure can help you achieve your final goal – a fit, firm looking body.
