 Gastric bypass

Turkey’s leading clinic – Istanbul

Gastric bypass surgery is one of the most popular surgeries for obesity and weight loss. This surgical procedure is performed at the XA Clinic in two main steps:

Stage one: This is done by dividing the stomach into two chambers, an upper chamber called (gastric sac), which will take in food and redirect it to the small intestine without passing through the duodenal ducts; Where he gets a small amount of food, about 30 grams.

The lower chamber is the largest and connects to the isolated part of the duodenum to reconnect with the small intestine. This step aims to reduce the size of the stomach and thus reduce the amount of food consumed.

The second stage is the process of isolating the lower chamber and duodenum, which reduces the secretion of certain intestinal juices and appetite-inducing hormones such as ghrelin, thereby reducing appetite and stimulating satiety when eating small amounts of food.

This step will help type 2 diabetics avoid sugar intake and thus maintain blood sugar levels.

Everything You Need to Know About Gastric Bypass Surgery

How is the process of changing the gastric bypass?

The stages of gastric bypass surgery can be divided into three main stages:

Preoperative procedures:

  1. The doctor first requests a medical examination before scheduling an operation date to avoid any risks that may arise during or after the operation.
  2. The patient’s medical history is carefully reviewed and the usual dosage of medication is adjusted for the patient if he or she has some chronic illness or is taking any anticoagulants.
  3. Stop taking all tobacco products 4 weeks before surgery, so as not to reduce the body’s ability to recover.
  4. Eat a low-calorie, high-protein diet 2-3 weeks before surgery to reduce the amount of fat around the liver to help the body heal and increase the likelihood of success.
  5. Do not eat 8 hours before surgery.

Laparoscopic Gastric Bypass Procedures:

  1. The operation is performed under general anesthesia after an initial check of vital signs.
  2. The doctor makes several simple incisions that do not exceed 2 cm around the abdomen, where the endoscope and surgical instruments are inserted.
  3. The stomach is divided into two parts: the simple upper part, which is fixed with medical stitches and called (gastric pocket), where it is small in size to accept food coming directly from the mouth and only takes 30 grams of food and liquid.
  4. The doctor connects the upper stomach to the small intestine at a distance of 100 to 150 cm from the front of it – to bypass the part responsible for the secretion of satiety hormones and reduce the absorption of sugars and fats in this part – where he connects them with surgical sutures and staples preventing leakage of intestinal juice and food. Then a new alimentary canal forms.
  5. The lower part of the stomach is held together with staples and attached to the separated anterior part of the small intestine, where it is sutured again and connected to most of the small intestine.
  6. The doctor checks to see if the new intestinal ducts are plugged in and if there is any leaking digestive fluid.
  7. The incisions are sutured with a cosmetic method, then the anesthesia is discontinued and the patient is transferred to his room.

  2. These days, you may feel tired, nauseous, loss of appetite, bloating, which are normal, and will go away with some of the medicines prescribed by your doctor.
  3. Some light activities are performed with the help of medical personnel, such as standing by the bed, simple walking, and deep breathing exercises in the first days after surgery to maintain healthy circulation and speed up the recovery process.
  4. After making sure that the operation is successful and that there are no side effects, the doctor decides whether the patient is ready to leave the hospital and draws up a detailed treatment and nutrition plan to be followed at home.
  5. The patient remains on liquid food for 2-3 weeks after surgery, after which he is allowed to eat light and then regular food.
