How Does it Work?

Gastric bypass surgery is an invasive surgical procedure that involves dividing the stomach into a small upper pouch and a larger lower pouch. The basic idea of this surgery is to shrink the size of your stomach so that you don’t eat as much food as you used to.

What Does a Gastric Bypass Surgery Involve?

Each and every gastric bypass surgery procedure is tailored to suit every individual’s needs, preferences, and the clinic’s best practices. when you arrive at the clinic, you will have your final consultation which will be done face-to-face between you and your surgeon.

When you have both gone through the details of the Gastric bypass surgery, your surgeon will begin to prepare you for the procedure. Here is what to expect during the surgery:

1.     Taking the anesthesia

To make you feel comfortable during the surgery, your surgeon will give you general anesthesia right before the surgery commences.

2.     Procedure

When you are anesthetized, the surgeon will start the procedure. Although some surgeries are still performed with traditional large (open) incisions, most are performed laparoscopically, which involves inserting instruments through multiple small incisions in the abdomen.

Once the general anesthesia is applied, your surgeon will make incisions and then cut across the top of the stomach. After dividing the top of the stomach from the rest of the stomach, the bottom end of the divided small intestine is brought up and connected to the newly created small stomach pouch.

This pouch is going to be a walnut-size, and it can hold only an ounce of food.

3.     Post-Op Instructions

You can start low-intensity activities immediately after the surgery and this is a very important part of your recovery process. It basically helps to prevent pneumonia, blood clots, and constipation, and it increases weight loss. Your surgeon can also guide you on pain control and postoperative medical tests.

The most important part of post-operative instructions contains diet.


What Should I Eat After Gastric Bypass Surgery?

  • For the first postoperative day and for the next few days, you can consume only clear liquids such as water, broth, and plain gelatin. It is important that you should sip slowly and consume up to 50-100 ml at a time.
  • If you do not experience a problem with clear liquids, you can start to consume other fluids such as fat-free or low-fat milk.
  •  If you don’t experience any problem with fluids for several days, you can start to eat mashed foods.
  • After you consume purees and mashed food for several weeks, small, easily chewable foods can be added to your diet with the consent of your surgeon
  • After 8 weeks, you can start eating solid foods, slowly. At this stage, you should slowly switch to normal foods to see which of them you can tolerate. Three to four months after surgery, you may switch to a normal healthy diet depending on your recovery level, physician guidance, and food tolerance.

Things You Should Do Before Surgery

  • A week before the procedure, you should stop taking Aspirin and any other meds associated with blood thinning.
  • If you are allergic to any drugs, you should inform your surgeon as soon as possible.
  • Patients are advised to avoid smoking 24 hours before the surgery.
  • Consuming any alcoholic beverages can affect anesthesia. So you should not take in anything alcoholic 24 hours prior to surgery.
  • If you are taking meds for chronic or acute diseases such as diabetes and heart disease, you should inform your surgeon before the surgery commences. 



Is Gastric Bypass Painful?

You may feel pain or soreness after the procedure is done. However, your surgeon may prescribe painkillers to relieve this pain and discomfort.

What Are the Effects of Gastric Bypass Surgery on Weight-Related Diseases?

Gastric bypass is one of the most effective methods for achieving the ideal weight of morbidly obese patients and it has a significant effect on the treatment of weight-related diseases caused by morbid obesity such as gastroesophageal reflux disease, heart disease, type 2 diabetes, high blood pressure, obstructive sleep apnea, and high cholesterol.

How Much Weight Will I Lose with The Gastric Bypass Surgery?

On average, gastric bypass surgery patients lose between 50 to 80 percent of excess body weight within 12 to 18 months after the procedure.

    I had a great experience! Flymedi were amazing, Kirsty would message back quickly and was always polite. Dr Murat Aynaci is a very kind and talented man. The hospital staff in the day was fantastic, however, my only dissatisfaction was staff didn’t answer the call bell at night. I waited 90 minutes before making my way to find someone and noticed every call light was on in my corridor. There was staff at the front desk. This happened the two nights I tried to request help. Once for pain and once because my drip came out. Overall my experience was great however if I traveled alone I would have been scared if no one came when requesting help in the night. Thank you so much, this is life-changing and I am so happy.
