How Does Gastric Sleeve Work?

Overview Gastric Sleeve

A surgical weight-loss surgery is a sleeve gastrectomy, sometimes known as a vertical sleeve gastrectomy. Laparoscopic surgery is frequently used for this operation, which entails introducing tiny instruments through numerous tiny incisions in the upper belly. The stomach is removed from the body during a sleeve gastrectomy, leaving behind a tube-shaped stomach that is roughly the size and shape of a banana.

Your ability to eat depends on how much food you can fit in your stomach. The surgery also triggers hormonal adjustments that help with weight loss. The same hormonal changes also aid in treating diseases like high blood pressure or heart disease that are linked to obesity.

Why it’s done Gastric Sleeve

Sleeve gastrectomy is performed to assist you in losing excess weight and lower your risk of serious, maybe fatal, weight-related health issues, such as:

  • Heart disease
  • High blood pressure
  • High cholesterol
  • Obstructive sleep apnea
  • Type 2 diabetes
  • Stroke
  • Cancer
  • Infertility

Only after you’ve made an effort to reduce weight by altering your eating and exercise routines is a sleeve gastrectomy often performed.

In general, you might be a candidate for sleeve gastrectomy surgery if:

  • Your body mass index (BMI) is 40 or higher (extreme obesity).
  • Your BMI is 35 to 39.9 (obesity), and you have a serious weight-related health problem, such as type 2 diabetes, high blood pressure or severe sleep apnea. In some cases, you may qualify for certain types of weight-loss surgery if your BMI is 30 to 34 and you have serious weight-related health problems.

To live a healthier lifestyle, you must also be prepared to make long-term adjustments. Long-term follow-up programs that track your diet, way of life, and behavior as well as your health issues may be expected of you.

Find out if your health insurance coverage covers weight-loss surgery by contacting your local Medicare or Medicaid office or your health insurance plan.

  • Excessive bleeding
  • Infection
  • Adverse reactions to anesthesia

  • Gastroesophageal reflux
  • Low blood sugar (hypoglycemia)
  • Malnutrition
  • Vomiting

How you prepare Gastric Sleeve

You might need to establish a physical activity routine and give up smoking in the weeks before your operation.

You could have limitations on what you can eat, drink, and which drugs you can take before your surgery.

Planning ahead for your post-operative rehabilitation is an excellent idea right now. Organize assistance at home, for instance, if you anticipate needing it.

During the Gastric Sleeve

The specifics of your procedure will rely on your unique condition and the policies of the hospital or doctor. Some sleeve gastrectomies are performed with conventionally large (open) abdominal incisions. However, a laparoscopic sleeve gastrectomy requires introducing tiny devices through several tiny incisions in the upper abdomen.

Before your procedure, a general anesthetic is administered. During surgery, anesthesia is a medication that keeps you relaxed and drowsy.

When performing a sleeve gastrectomy, the surgeon removes the bigger, curved portion of the stomach and stitches the stomach vertically to make a narrow sleeve.

A typical surgery lasts one to two hours. You awaken in a recovery room following surgery, where medical personnel keep an eye out for any issues.

After the Gastric Sleeve

Your diet after sleeve gastrectomy starts with sugar-free, noncarbonated drinks for the first seven days, then shifts to pureed foods for the following three weeks, and then, about four weeks after surgery, to ordinary foods. For the rest of your life, you must take a multivitamin twice daily, a calcium supplement once daily, and a monthly shot of vitamin B-12.

In the initial months following weight-loss surgery, you will have numerous medical examinations to track your health. You could require numerous checkups, bloodwork, and laboratory tests.

In the first three to six months following a sleeve gastrectomy, you can notice changes as your body adjusts to the fast weight reduction, including:

  • Body aches
  • Feeling tired, as if you have the flu
  • Feeling cold
  • Dry skin
  • Hair thinning and hair loss
  • Mood changes


Long-term weight reduction may be possible after a sleeve gastroplasty. You must alter your living patterns in order to reduce weight. Within two years, you could drop 60% or even more of your extra weight.

The following problems associated with being overweight may be improved or resolved by sleeve gastrectomy in addition to weight loss:

  • Heart disease
  • High blood pressure
  • High cholesterol
  • Obstructive sleep apnea
  • Type 2 diabetes
  • Stroke
  • Infertility

How Does Gastric Sleeve Work?

Gastric Sleeve, as mentioned above, involves removing a large part of the stomach. Therefore, it reduces the stomach volume of the patient. In addition to the shrinking stomach volume, the patient’s stomach has a part that provides ghrelin hormone. With the removal of this part, the hunger hormone of the patient will also decrease. Thanks to both less secretion of hunger hormone and a smaller stomach volume, the patient will start to lose weight quite easily. With Gastric Sleeve treatment, you can lose weight by feeling less hungry and eating less portions.

Is Gastric Sleeve a Painful Procedure?

Gastric sleeve surgery does not involve making a large incision in your abdomen. Instead, it involves removing your stomach with the laparoscopic method with 5 small incisions. Therefore, it is not a painful treatment. According to the evaluations, gastric sleev gets 3 pain points out of 10. This also allows the patient to relax after the painkillers given. Therefore, they are not painful treatments.
