Gastric Sleeve: All You Need to Know
What Is a Gastric Sleeve?
Are you tired of maintaining diets and lifestyle changes and still not being able to lose weight? Or are you overweight with a BMI of 40 or more? Bariatric Surgery is an option for rapid weight loss, in which a part of your stomach will remove. Gastric Sleeve or sleeve gastrectomy is one of many types of bariatric surgery and is a surgical procedure opted for weight loss in which a portion of the stomach is surgically removed along its curvature to get a sleeve-like structure in reduced weight.
In this surgery, the stomach will reduce to 10 to 15 percent of its original size, which results in a sleeve or banana-like stomach being full early and restricting too much eating. You will lose weight by being able not to eat too much and also due to fewer appetite-stimulating hormones. If you are looking to have a gastric sleeve for weight loss, you must know all its aspects as described below.
How Gastric Sleeve Performed?
Gastric sleeve is generally performed under general anesthesia as a minimally invasive procedure via laparoscopy (in which a long thin tube with instruments and a camera is passed inside your stomach via small incisions and surgery is performed). In the surgery, the stomach is divided into two unequal parts, with the outer 80 to 90 percent removed and the inner being made into a sleeve.
The surgery will continue for an hour, after which you will monitor for another hour in which you will wake up from anesthesia and your vitals will monitor. After that, you will monitor for a day or two for post-operative care and then be discharged. As the surgery is minimally invasive, it generally heals quickly without any complications. Unless you have any complications, you’ll be able to go home after 2 to 3 days.
How Gastric Sleeve Is Different from Gastric Bypass?
In gastric bypass, the surgeon makes a small pouch that skips most of your stomach, going straight into your stomach. On the other hand, a gastric sleeve is a surgery for dividing your stomach and removing a part of it. A gastric sleeve is best for people who have a BMI of 40 or more, which means weighing 100 pounds above your ideal level. Gastric sleeve surgery is a good alternative surgery for those people who are too heavy for bypass surgery.
How Effective Is a Gastric Sleeve?
You must be wondering if the gastric sleeve is effective, yes, it is, it helps you lose weight in two ways.
- Your stomach is relatively smaller now and you will feel full early which means you will consume fewer calories in total and will lose weight.
- The part of the stomach that produces ghrelin (a hormone that stimulates hunger) is now removed and you will feel less hunger and less food intake.
Both these factors help you in losing weight and according to studies, the majority of people can expect to lose half their excess weight in just 18 to 24 months following gastric sleeve surgery, and some others may lose even more. (as per the American Society of metabolic and bariatric surgery).
Are There Any Risks and Complications?
Is gastric sleeve surgery completely safe, absolutely not, as with any other surgery, there are also some minor risks and complications, although it is a relatively much safer procedure. This is why it’s imperative to find a trustworthy surgeon, like Dr. Joshua Long of BMCC, that is willing to take the time to listen and understand your individual needs. Some complications that may occur following surgery are,
- Hemorrhage from the incision site or internally.
- Deep vein thrombosis (DVT) following the surgery.
- Vitamin deficiencies (part of the stomach removed is responsible for vitamin absorption)
- Pulmonary embolism.
- Irregular heartbeat. (especially atrial fibrillation)
- Gastric leaks. (due to improper stitching or incomplete wound healing)
- Heartburn (GERD)
How Will Be Your Diet After Gastric Sleeve?
You’ll have to agree to a certain lifestyle and diet modifications; before you opt for gastric sleeve surgery, as diet helps to achieve and maintain weight loss. Your surgeon will recommend a healthy diet for the rest of your life and the guidelines may include increasing protein, lowering carbohydrates, and eliminating sugar from your diet two weeks before surgery.
Use only liquids two days before and a week after the surgery; you can add pureed food for the next week. After that, you’ll follow a recommended good diet. Some Other points to keep in mind are as below,
- You must chew your diet properly before you swallow it.
- Do not drink while you eat as this may overfill your relatively small stomach, and drink liquids before or after half an hour of your meal.
- Avoid high-calorie sodas/snacking and take vitamin and mineral supplements every day.
After 2 or 3 months, you will be able to have regular meals but keep in mind that you will not be able to eat as much as you used to.
Gastric sleeve surgery works by making your stomach smaller; so you eat less, consume fewer calories, and you’ll also find that you’re less hungry.
Before opting for gastric sleeve surgery, you must have tried other weight-loss methods; including diet, exercise, and weight loss medications — and they have not shown any significant benefits. Moreover, your BMI must be 40 or more to qualify.
After surgery, following diet and lifestyle modifications, you see significant weight loss in 24 months. Although a safe surgery, it may have some risks, so talk to your doctor and clarify all your queries beforehand.
