Gastric Sleeve Surgery

If you are living with obesity and can't seem to lose weight through diet and exercise alone, it may be time to consider bariatric surgery.

The gastric sleeve procedure is one of the most popular and most effective weight loss surgeries in modern bariatrics.

At Northwest EndoSurgical serving Houston, Texas, we help patients lose weight with the gastric sleeve. Could it be right for you?

​How Does Gastric Sleeve Surgery Work? The Basics of Sleeve Gastrectomy

image depicting how gastric sleeve works

Gastric sleeve surgery (sleeve gastrectomy) involves removing a significant amount of stomach tissue so the stomach is reduced in size to a small tube or sleeve. When the size of the stomach is reduced, patients require less food to feel full. Meanwhile, the reduction can trigger hormonal changes in the body which contribute to additional weight loss and improvement of weight-related health conditions.

​The Benefits of Gastric Sleeve Surgery

Appetite Suppression

Gastric sleeve surgery involves reducing the stomach to less than half of its original size. A smaller stomach will result in you feeling full after eating less food, gradually producing healthy weight loss.

Minimal Scarring

Because Dr. Matthew St. Laurent is a surgeon who prefers to operate laparoscopically, the scarring from the surgery is minimal. The procedure only requires four or five small incisions in the abdomen that are less than half an inch long.

Improved Health

As you lose weight after your gastric sleeve surgery, obesity-related health conditions like Type 2 diabetes, obstructive sleep apnea, high cholesterol, high blood pressure, and more can improve.

Life-Changing Weight Loss

Within a year, many patients lose around 60-70 percent of their excess body weight, if not more. A healthier body and slimmer figure can help you take on the world with improved energy and confidence.

"​I'm so thankful."

"I had the Gastric Sleeve procedure on 9.8.2016. I have lost 92 pounds to date and still losing. For the first time in a long, long time I feel like I have control over my food consumption and addiction instead of it controlling me. I can't begin to tell you how much this procedure and this journey has changed me as a person both mentally and physically. This was a major decision in my life and I'm so thankful I had Dr. St. Laurent as my doctor. I wish I could give him more than 5 stars!" Tracy Mross, 5-Star Review

Our Bariatric Expert Discusses the Life-Changing Gastric Sleeve Procedure

Houston patients are often reassured by the way Dr. St. Laurent clearly explains his procedures. In less than two minutes, he describes the benefits and advantages of the gastric sleeve. This procedure is especially popular for its simplicity and swift recovery. After your gastric sleeve, you can begin working within the week and lose more than two-thirds of your excess weight in the first year. 

Watch Our Surgeon Perform Gastric Sleeve Surgery

With a gastric sleeve, or sleeve gastrectomy, Dr. St. Laurent can remove a major portion of your stomach before reshaping it into a much thinner, tube-like sleeve. This reduces hunger and allows you to feel more full with less food. The video above showcases our Dr. St. Laurent's immense skill at performing laparoscopic gastric sleeve surgery. 

Dr. St. Laurent's Team Elevates Patient Results

How Much is Gastric Sleeve Surgery?

Gastric sleeve surgery falls in the mid-price point of bariatric surgeries. It's less than gastric bypass surgery but slightly more than gastric band surgery. Pricing will vary but can be as low as $335 per month, thanks to our financing plans.

Gastric Sleeve Timeline What to Expect


During a consultation with Dr. St. Laurent, he will conduct an examination and recommend if he thinks bariatric surgery is right for you. He will cover all possible risks, costs, and necessary lifestyle changes. If you and the doctor decide gastric sleeve is the best choice, your procedure can be scheduled.


In the two-week period leading up to your surgery, Dr. St. Laurent's dietitians will recommend a dietary program for you, which will include low-carb foods and protein shake supplements. He may also advise you to stop taking certain medications or forgo smoking and alcohol.


When you come in for your weight loss surgery, you will be put under general anesthesia, so you will be totally unconscious during the procedure.


Dr. St. Laurent will make several small incisions around one-fourth to one-half of an inch in length in the abdomen. The surgeon will insert a laparoscope, or tiny camera, through one of these small incisions to broadcast images to a nearby video monitor. These images will guide Dr. St. Laurent in performing the operation.

Sleeve Gastrectomy

The surgeon will remove a sizable section of stomach tissue, reducing it to less than half of its normal size. The remaining stomach tissue will be a thin, vertical “sleeve,” which is then stapled shut. Dr. St. Laurent will then remove all of his surgical tools and sew the incisions closed.


To reduce the chances of serious complications after bariatric surgery, it is important to follow our recovery instructions very carefully. A patient manual will be provided. Your diet will be restricted for around one month after surgery. In the beginning, you may consume only liquids and will gradually add solid foods back into your diet over time. You will also need to minimize the amount of food you eat at one time. It’s important to drink plenty of fluids during the recovery period to avoid dehydration and avoid constipation.

Weight Loss

As you recover from bariatric surgery and eventually resume normal activity, you will become full after eating less food. As your body absorbs fewer calories, you should experience dramatic weight loss in the first year. For the healthiest possible results, it is important to eat a nutritious diet and exercise regularly.

What Makes 
A Good Candidate?

This is what we look for when we meet with candidates in our Houston office:

Failed Weight Loss Efforts

The gastric sleeve, like any bariatric surgery, is only recommended when consistent diet, exercise, and weight loss medications have been unable to treat weight issues. 

Severe Obesity

A BMI of 40 or higher would put you in this category. Genetic factors can play a role in causing extreme obesity and can make it incredibly difficult to overcome weight issues without medical intervention such as a gastric sleeve.

Weight-Related Conditions

If your BMI is under 40, you may still be a suitable candidate for a gastric sleeve if you suffer from major health conditions caused by your weight, such as type 2 diabetes. 

Reflux and Esophageal Disease

Too much acid reflux can make a gastric sleeve the wrong decision. This is because the new shape of the stomach can worsen reflux. Similarly, certain esophageal diseases can be exacerbated by a gastric sleeve. If you suffer from these conditions, a gastric bypass should be discussed instead.

Find Out If Gastric Sleeve Is Right for You

Dr. Matthew St. Laurent has dedicated his life to providing solutions for people struggling with obesity and weight-related conditions.

Having performed thousands of bariatric procedures, Dr. St. Laurent has the experience to determine if the gastric sleeve is the right option for you, and to provide results that help you enter a new chapter of health and happiness in your life.

Our practice offers advanced body contouring with cutting-edge InMode technology. This contouring system allows us to tighten your body without additional surgical procedures. We proudly offer this service to patients so they can enjoy the effects of weight loss to the fullest.

Gastric Sleeve  or Gastric Bypass?

There are many different forms of weight loss surgery, but the most well-known are gastric sleeve surgery and gastric bypass surgery. Both are effective in helping patients lose weight, and both have similar recovery times and potential complications. The best surgical option for you is based on a variety of factors, including your weight and what underlying health conditions you have (for example, patients who suffer from acid reflux are better served by gastric bypass).

When you come into our Houston, TX, area office for your bariatric consultation, Dr. St. Laurent will help you determine which weight loss procedure is right for you.
