Substantial and Sustained Weight Loss Surgery

Gastric Sleeve

Sleeve Gastrectomy, or Gastric Sleeve is a type of bariatric surgery, intended to treat obesity by inducing weight loss. It is gaining popularity thanks to the simplicity of the procedure and the substantial amount of initial weight loss seen by patients.
Clinic 360 has been able to help many patients change their lives by offering this type of lifesaving procedure. Considered to be the new gold standard in weight loss surgeries, gastric sleeve is not only able to reduce the amount of food that the stomach can hold, but it can lower the overall body fat by modifying the signals that work between your stomach and your brain.

Is Gastric Sleeve Right for Me?

After exhausting diet and exercise options and finding out that these methods are not potent enough for your weight-loss needs, you may be ready to consider bariatric options, especially if your health is at risk.

Body Mass Index or BMI, which is a calculation based on your height and weight is one of the most determining factors that can help with your candidacy for gastric sleeve. Candidates need to have a BMI of 30 or higher. To find out what your BMI is, you can use the table below:

Other factors to consider are if you have a realistic expectation of the outcome of surgery, and if you are able to grasp what the surgery can and cannot do for you. Gastric Sleeve surgery is a tool that is intended to jumpstart your commitment to sensible eating habits and regular exercise. With that being said, the surplus of benefits that you can gain from Sleeve Gastrectomy including a longer and happier life can definitely make surgery worth it.

Once you have decided that you are ready for a change and are able to sustain a healthy, active lifestyle, the best way to find out if you are a candidate for gastric sleeve is to call Clinic 360 and make an appointment for a consultation. During your consultation you will be provided with the resources and professional advice to guide you in the right direction.

Advantages of Sleeve Surgery

There are 3 main bariatric surgeries available to patients: gastric bypass, gastric banding and gastric sleeve. They all have their advantages and disadvantages, however let’s run through the advantages of gastric sleeve:

  • Faster recovery
  • Shorter clinic stay
  • Minimally invasive
  • Small scars
  • Less risk of complications

Most of these advantages stem from the fact, that sleeve gastrectomy uses a minimally invasive technique, with a short operation time (ie- less time for you to be under anesthesia, which reduces complications of surgery that much more).

Health Benefits of Gastric Sleeve

With gastric sleeve you can lose 60-70% of your excess weight. This calculation is also referred to as Expected weight loss, and it is an estimate as to how much of your excess weight you will lose after surgery. The result of losing so much weight, and one of the other main goals of sleeve gastrectomy is to provide you with a healthier life. Within the first year to 18 months after surgery patients are expected to see the most results, which include many obesity related diseases such as:

  • Dramatic Weight Loss
  • Reduced Cholesterol
  • Reduced Blood Pressure
  • Control/Remission for Type II Diabetes
  • Controls Sleep Apnea & Improves Sleep Quality
  • Decreases Joint/Muscle pain
  • Overall Better Quality of life
  • Increased Mobility
  • Improved Confidence

How Does Gastric Sleeve Cause You to Lose Weight?

Gastric sleeve is a two-fold procedure as it not only changes how much food a person is able to hold, but how much food a person wants, both which help to induce weight loss.

  1. Since your stomach is now smaller in size then it was before, you now feel satisfied (full) with smaller amounts of food.
  2. Ghrelin, which is known as the hunger hormone, is mainly produced in the stomach, especially in the portion of the stomach that gets removed during sleeve gastrectomy. Normally in between meals when the stomach is empty, ghrelin is produced and signals are sent to the brain to give us the urge to eat. By removing a large concentration of ghrelin, which is what happens after gastric sleeve surgery, you can wait longer in between meals before feeling the need to eat again, and you also feel satisfied with less amounts of food.

The gastric sleeve surgery is permanent, but it does not affect anything critical as to how the stomach naturally works. The surgery has minimum effects on the digestive process, which reduces the risk of malabsorption complications, which can be seen in other types of bariatric procedures such as gastric bypass.

How is Gastric Sleeve Performed?

The Gastric Sleeve procedure takes about 1.5 hours and is completed under General Anesthesia, meaning you will be put to sleep. Surgery is performed in one of our two operating rooms at Clinic 360, with the best possible surgical team.The surgeon(s) will mark the incision sites pre-operatively forming a ‘U’ shape around your abdomen. These incision sites are very miniscule, leaving the scars to be almost invisible.

The surgeon(s) enter the stomach laparoscopically using trocars. A camera is inserted through one of the trocars, this allows them to have a visual of the stomach through a video monitor and to precisely guide other instruments. Other instruments are then inserted through the other trocars for the removal and stapling of the stomach.

They remove 75-80% of the original stomach, leaving a sleeve-like portion, very similar looking to a banana. The connections to your esophagus and small intestines are left intact.

The remaining stomach is sealed using staples, and the incisions on the abdomen are sutured up. Before surgery the average stomach is able to hold 4-6 cups, after surgery it will be able to hold ½ – 1½ cups.

A Glimpse into Gastric Sleeve Recovery

Once the surgery is finished you may think that the roughest part is over, however surgery is just the beginning of the journey you will undergo to a healthier new you. It will be a great help to you to have as many loving and supporting family members as possible around you before surgery, and the months after surgery. This will help give you courage and strength to keep an active lifestyle, since you will go through many emotional and physical changes. One of the most important things to remember to ensure your sleeve gastrectomy is a success is to understand that surgery is not just a “quick fix”, and you must commit to a “complete lifestyle change” for the rest of your life.

Directly after surgery you will need to stay overnight at Clinic 360. For the first week you will be on a liquid only diet, with restriction as to what you can and cannot consume. This is why you meet with a nutritionist weeks before your surgery in preparation for this phase. The next day you will be discharged and sent home. For the next couple of weeks you will be consuming liquid to blended foods, to settle your stomach. Once you reach the 2 month mark you can progress to a regular diet as tolerated with restrictions to portion sizes.

It will take up to 18 months to lose the expected weight. Most patients lose about 60%-70% of their excess weight. You will lose weight rapidly after the first few months and this loss will most likely plateau. This is expected; however don’t let this discourage you from losing the rest of your weight. Plateauing is just a way of your body getting used to the grand change it has undergone. There are many ways to overcome this such as adding in a new external change to your exercise regime.

Knowledge and preparation of the gastric sleeve surgery are two great ways to help you with the success of the procedure and to changing your life for the better. At Clinic 360, we are here to help you every step of the way!

Steps to Booking Sleeve Gastrectomy at Clinic 360

The initial step at Clinic 360 is booking a free consultation. This can be achieved over the phone with our highly trained surgeons, or at our clinic. In this step, the surgeon(s) will determine what course of action should be taken to help you maintain a healthy lifestyle while also achieving your weight loss goals.

Following this, once you feel comfortable and confident in the diagnosis from the doctors and you are a viable candidate for the Gastric Sleeve procedure, a surgery date can be secured.

Once your date is secured there are a few things that need to be completed by you. You would need to:

  • Review and complete the provided consent forms
  • Fill out a patient health questionnaire
  • Get bloodwork and an ECG done at your local lab
  • Book a pre-op appointment with the anesthesiologist
  • Book an appointment with our nutritionist

The pre-operative appointment is done with the Anesthesiologist so that he/she can get a better understanding of your medical history. At Clinic 360 we want to address all and any health concerns that may come up, to ensure you receive a comfortable and at most, pain free experience.

The appointment with the nutritionist is important as it becomes the stepping stone to help with the adjustments which are going to be made in your diet. Figuring out what foods you will be comfortable with and what kind of diet will best help your weight loss journey are vital.

Question we get asked a lot - “Does your stomach stretch after surgery?”
Simple answer is yes, stomach stretching is normal and is expected to happen, but it is unlikely that it will stretch back to the original size.

Stomach stretching is mostly due to overeating, which can lead to a permanent increase of the stomach size. As the stomach grows, it demands more food to feel satiated, as hunger and fullness signals are skewed. This is one of the reasons why some people find it difficult to maintain weight loss after one year post-op.

Ways to Minimize Stomach Stretching
🔹Avoid overeating by planning small meals
🔹Eat slow and chew chew chew, so your stomach can properly digest the food
🔹Don’t drink while you eat. Wait 30 mins before or after you eat
🔹Schedule small snacks to avoid grazing
🔹Make sure you are having enough protein, so you will feel fuller for longer
