How gastric sleeve is done 

Gastric sleeve involves cutting out a large portion of the stomach until about 15% of the stomach is left. There are two major types of gastric sleeve:

  • Normal Sleeve: About 80% of the stomach is removed. This method is for people with a BMI (Body Mass Index) of more than 40.
  • Mini Sleeve: About 60% of the stomach is removed. This method is undergone by people with a BMI that is between 30-40.

One way or another, the procedure permanently removes a majority of your stomach. Whatever is left of the stomach looks like a vertical tube or a sleeve with the size of a banana. The remaining sections of the stomach will hold a smaller volume of food (and calories) that can be consumed. It should be noted that sleeve gastrectomy is a physical as well as an emotional procedure. That's why some patients are required to visit a psychologist when considering gastric sleeve.

Laparoscopic sleeve gastrectomy

In most cases, sleeve gastrectomy is performed laparoscopically. That is, the surgeon makes some incisions in the abdominal area and inserts a camera (laparoscope) along with some surgical instruments through these incisions. The surgeon will then use them to operate the procedure. It is a popular way of performing sleeve gastrectomy. One of the most important benefits of this technique is that the scars will be almost invisible. The procedure will approximately take 2 hours and is performed under general anesthesia.

Will gastric sleeve work for me?

If you have a BMI between 30-50, are suffering from problems associated with obesity and have unsuccessfully tried other non-surgical weight-loss methods, you can certainly be a candidate of gastric sleeve. It is a very efficient procedure with a fast recovery. You can see immediate weight loss within the first six months and the side effects will be minor. Patients with diabetes or PCOS (Polycystic ovary syndrome) can benefit from the procedure; studies show that in some cases, VSG helps improve the symptoms of PCOS. It is vital that you stick to a healthy diet and exercise routine to ensure a fast recovery and optimal outcome. 

BMI range

When it comes to Gastric Sleeve or any type of bariatric procedure, BMI or Body Mass Index is a vital element to be taken into consideration. It determines whether the person needs to undergo the surgery or not; and if so, what type of sleeve gastrectomy he/she should try. Patients with a BMI higher than 30 are candidates for gastric sleeve surgery.  Calculate your BMI

Sleeve surgery weight loss timeline

With the gastric sleeve surgery, the weight-loss process begins almost immediately. Approximately 70% of your body's excess weight will be gone within a couple of years. With the proper diet and exercise, you will see more weight loss too. Your post-op average weight loss estimations can be as follows:

  • In 3 months: 33%
  • In 6 months: 50%
  • In 12 months: 65%
  • In 18 months: 70%

Some bariatric surgeries may need revision surgery after several years. The gastric sleeve surgery may not need a revision as often as other types such as gastric band surgery. According to some researches, after two years of sleeve surgery, the patient's volume of the stomach may increase; if he/she neglects to have a healthy lifestyle and diet plan, a revision sleeve gastrectomy may be needed.

What you need to do before getting gastric sleeve surgery 

  • Maintain a liquid diet 24 hours before the surgery
  • Both the previous night and the morning before the surgery, take a shower and wash the area with antibacterial soap and water.
  • Do not apply any kind of fragrance or lotion on the area.
  • Do some cardio workouts to burn some fat and help your heart's activity.

Aftercare and recovery tips

You can add flavors like lemon, cucumber or ginger to your water. Your post-op diet consists of mostly liquid food and then gradually you can go for puree. After 3 weeks you should be able to eat soft foods and in 4-5 weeks, you can resume your normal solid food.
  • Take daily supplements like zinc and biotin to minimize the post-surgery hair-loss.
  • Minimize drinking liquids during the meal
  • Drink 64 ounces of water daily
  • Eat small, frequent meals

Long-term weight-loss diet plan

About 1-2 months after your surgery, you can resume a healthy, solid food diet. You are required to have a diet of fresh, whole food with main focus on protein. A diet including protein shakes, lean meats, seafood, lentils, nuts, fruits, and vegetables will be extremely helpful.

Are gastric sleeves safe?

Compared to many other common surgeries, gastric sleeve is a relatively safe surgery. Deaths from this surgery are extremely rare and if done by a competent surgeon, it has minimal complications.

Does gastric sleeve surgery hurt?

In a laparoscopic gastric sleeve, the incisions the surgeon makes are minor (about 1.5-inch-long) and are unlikely to scar or lead to severe pain. Although, you may experience some tenderness and soreness in the area for one week or two.

Does gastric sleeve work long term?

You will continue to lose weight up to 5-10 years after the surgery. Continued success depends on whether or not you maintain a healthy lifestyle.

Studies show that any bariatric surgery can lead to hormonal changes. Being overweight results in more estrogen in the body. Consequently, weight-loss decreases estrogen levels and increases testosterone to estrogen ratio. Testosterone is associated with higher energy and sex drive.

Gastric sleeve reversal is rarely needed; and in the opinion of most surgeons, this invasive procedure is unable to be reversed. 

Does Gastric sleeve affect pregnancy?

It is best to wait at least 12 to 18 months after surgery and let your weight to be stabilized before you get pregnant. A pregnancy that occurs too soon after the weight loss surgery can lead to severe consequences for the mother and the baby.
