The objective of the Gastric bypass surgery

It is an operation that helps you lose weight by modifying the way in which your stomach and small intestine manage the food you consume.

After the surgery, your stomach will become smaller. You will feel full with less food intake.

The food you eat will no longer go to specific parts of your stomach and your small intestine which absorb them.

Thereby, your body will not receive all calories derived from the food you eat.


The gastric bypass surgery is carried out under general anesthesia. You will be sleeping and would not feel any pain.

There are two steps during the gastric bypass:

The first step reduces the stomach. The surgeon uses staples to divide the stomach into a small upper section and a bigger low section. The upper part of the stomach (called a bag) is the place where the food you eat will go.

This bag has approximately the size of a nut and only contains about 28 grams of food. Therefore, you eat less and lose weight.

The second step is the circumvention. The surgeon links a little part of the small intestine (the jejunum) to a small hole in the bag. The food you integrate will now pass from the bag to this new opening in the small intestine. Consequently, your body will absorb less calories.

The gastric bypass can be done in two different ways. In open surgery, the surgeon performs a big surgical intervention in order to open the abdomen. The shunt is done while working on the stomach, the small intestine and other organs.

Another method for executing this surgery is to use a tiny camera, called laparoscope. The laparoscope allows the surgeon to see inside your abdomen.

In this surgery:

The surgeon makes 4 to 6 small incisions in your abdomen

The laparoscope and necessary instruments for the surgery are inserted in these incisions.

The camera is connected to a video monitor in the operating room. This enables the surgeon to see the interior of his abdomen while operating.

The advantages of the laparoscopy compared to the open surgery include:

A shorter hospitalization period and a faster recovery

Less pain

Smaller scars and weaker risks to have a hernia or an infection

This surgery lasts approximately from 2 to 4 hours.

Before the operation

The surgeon will ask you to pass tests and to consult other health care providers before undergoing this surgery. Some of them are:

A complete physical examination

Blood tests, a gall bladder scan and other tests to ensure that you are in a good health to go through an operation.

You consult your doctor to make sure that the other medical problems which you may have, such as diabetes, high blood pressure and other heart or lung issues are mastered.

Nutritional advice

Classes to help you understand what will be happening during the surgery, what to expect after the surgery, and the risks and problems that may occur later on.

You can consider consulting a professional advisor to make sure you are emotionally ready to be operated. You should be capable of making great changes in your lifestyle after the surgery.


The majority of people lose between 4,5 and 9 kilograms per month during the first year after the surgery. Weight loss process will decrease with time. By adhering to the diet and the exercice program, you lose more weight.

You can lose half or more of your additional weight during the first two years. You lose weight quickly if you always stick to a fluid or soft diet.

Losing weight after the surgery may improve several diseases, especially:

  • Asthma
  • Gastroesophageal reflux
  • High blood pressure
  • High cholesterol
  • Obstructive sleep apnea
  • Type 2 diabetes

Weighing less also helps you mobilize and carry out your daily activities.

To lose weight and avoid complications following the intervention, you will have to follow the exercice and food instructions that the doctor and the nutritionist have given you.
