Gastric Bypass

About Gastric Bypass

Gastric bypass surgery is a weight loss surgery to shrink the size of stomach and prevent the patient to eat as much as before. During the surgery, the surgeon re-routes or bypasses part of the digestive system to avoid absorbing much food.

 

You should know that the gastric bypass is not a reversible procedure. This surgery is done when diet or exercise haven’t worked and the person faces serious health problems because of the obesity or being overweight.

 

This surgery also helps cure type 2 diabetes. Up to 70% of type 2 diabetic patients are cured or their need for insulin is significantly decreased.

 

Gastric bypass surgery is not the only solution for surgical weight loss. Gastric Sleeve, Gastric Pelication, and Gastric Band are among other procedures leading to the same result.

Before Gastric Bypass

Before surgery the patient will meet with the surgeon for an examination. The surgeon will explain how the procedure is done and let the patient know the risks and complications of the surgery. Some lab tests are required to make sure the patient is in good health for this surgery.

 

Other general recommendations before the procedure are:

 

  • Tell the healthcare provider if you are allergic to any medicines
  • Get lab testing or a medical evaluation
  • Avoid taking any medication without the prescription of your doctor.
  • Stop smoking and drinking alcohol two weeks before the surgery
  • Exercises might be needed before the surgery
  • Tell the doctor about your medical history or if you have any health problems such as diabetes
  • Discuss any concerns with your healthcare provider before the surgery and make sure you are aware of every steps of this procedure

How is Gastric Bypass performed?

To do the gastric bypass surgery, the patient needs to go under general anesthesia. Depending on the patient's condition, there are two techniques to do the surgery. The traditional technique, in which large and open incisions are made, and the laparoscopical technique, which is done by inserting an instrument through multiple small incisions.

 

In both techniques, the surgeon cuts part of the upper stomach making a small pouch, then sews it directly to the part of the intestine. As the result, the food bypasses most of the stomach and goes directly to the middle part of the intestine.  

 

The surgeon then stitches the incision part and wraps it with bandages. The patient goes to recovery room and will need to stay in hospital for a few days.

  • Follow doctor instructions to care surgical site. Keep the surgical area clean and dry.
  • Follow the diet program that the doctor offers:
  • For the first two days after the operation, eating is not permitted;
  • For the first two weeks, liquids and soft foods (wholemeal soup, juices, stew, milk and other soft foods with rich nutrition) are recommended;
  • For the second two weeks, pureed foods are recommended;
  • After 4 weeks, you are permitted to eat solid foods, like small slices of meat or chicken, fruits and cooked vegetables;
  • Drink 6 to 8 glasses of water every day during the recovery period;
