Gastric bypass is an operation that helps you lose weight by changing the way your stomach and small intestines process the food you eat. After the surgery, your stomach will become smaller. You will feel fuller by eating less food. The food you eat no longer ends up in some parts of the stomach and small intestine that absorb food. Because of this, your body will not get all the calories from the food you eat. You will be given general anesthesia before your surgery. You will sleep and pain-free.
The operation of the gastric bypass is performed in 2 stages:
In the first stage, the stomach becomes smaller. Your surgeon uses staples to divide the stomach into a small upper part and a large lower part. The top of your stomach (called the pouch) is where you eat. The bag is the size of a walnut. It only holds about 1 ounce (ounce) or 28 grams (g) of food. This will help you eat less and lose weight.
The second step is bypass. Your surgeon connects a small part of your small intestine (jejunum) to a small opening in your bag. The food you eat will move from the pouch into this new opening and into the small intestine. As a result, your body will absorb fewer calories.
A gastric bypass can be performed in two ways. In open surgery, the surgeon makes a large surgical incision to open the abdomen. Bypass surgery is performed by acting on the stomach, small intestine and other organs.
Another way to do this is to use a tiny camera called a laparoscope. This camera is in your stomach. The operation is called laparoscopy. The scope allows the surgeon to look inside your abdomen.
In this operation:
- The surgeon makes 4 to 6 small incisions in the abdomen.
- Through these incisions, the telescope and the instruments necessary to perform the operation are introduced.
- The camera is connected to a video monitor in the operating room. This allows the surgeon to look inside your abdomen during surgery.
The advantages of laparoscopy over open surgery include:
- Shorter hospital stays and faster recovery.
- Less pain.
- Fewer scars and less risk of hernia or infection.
- This operation takes 2 to 4 hours.
Who Is Eligible For Gastric Bypass Surgery?
In general, gastric bypass and other weight loss surgeries may be an option for you in the following situations:
Your body mass index (BMI) is 40 or higher (extremely obese).
Your BMI is between 35 and 39.9 (obesity) and you have serious weight-related health problems such as type 2 diabetes, high blood pressure, or severe sleep apnea. In some cases, if your BMI is between 30 and 34 and you have serious health problems related to weight, you may be eligible for certain types of weight loss surgeries.
But gastric bypass is not suitable for everyone who is overweight. To be candidate for weight loss surgery, you may need to follow certain medical guidelines. You will most likely go through a rigorous selection process to determine if you qualify.
You also need to be prepared for constant change in order to lead a healthier lifestyle. You may need to participate in long-term follow-up plans that include monitoring your diet, lifestyle and behavior, and your health.
How Much Weight Can You Lose With Gastric Bypass Surgery?
You can expect to lose 60 to 80 percent of your excess weight as a result of gastric bypass surgery. Most of the weight loss occurs in the first 18 months after surgery. There is a risk of weight regain after surgery, but gastric bypass surgery has one of the best long-term weight loss profiles compared to other primary treatments for morbid obesity.
Gastric bypass is a way to reduce weight to a healthy level. Once your weight has dropped, you will need to develop healthy habits that support or improve your weight loss. Below are a few healthy habits to help maintain and / or improve overall weight loss after surgery.
- Eat three small, high-nutrient meals a day.
- Exercise 3-5 times a week.
- Write down what you eat.
- See your surgeon as recommended. You will be surprised to know how many people are not coming back after 6 months.
- Attend support groups.
- Make friends, join forums.
- Encourage your family members to lead healthy lives.

Benefits of Gastric Bypass Surgery

Recovery After Gastric Bypass Surgery
Recovery time will depend on the size of your incision. If you have had laparoscopic gastric bypass surgery, you will most likely stay in the hospital for 2-3 days. If your surgery is an open procedure (larger incision), recovery and hospital stay may take longer.
In the first days after surgery, the incision area will be painful. In the hospital, this can be easily dealt with medication. Your surgeon will most likely ask you to get up and walk on the day of your surgery. This helps remove any gas left over from insufflation (air used to expand the abdomen and create space for work) used during the procedure. You will most likely be asked to walk around the hospital floor at least 3 times a day after your surgery.
After Gastric Bypass Operation
Most people stay in the hospital for 1 to 4 days after surgery.
- On the same day you have your surgery, you will be asked to sit on the edge of your bed and walk for a bit.
- You may have a (tube) catheter that goes through your stomach for 1 or 2 days. This tube helps drain fluid from the intestines.
- You may have a catheter in your bladder to remove urine.
- You will not be able to eat for the first 1–3 days. After that, you can eat liquids, and then mashed or soft foods.
- You may have a tube connected to most of your stomach that was bypassed. The catheter will come out of your side and drain fluid.
- You will wear special stockings on your legs to prevent blood clots.
- You will receive injections of medication to prevent blood clots.
- You will receive pain relievers. You will take pain pills or receive pain relievers through an IV line, a catheter that is inserted into your vein.
- You can eat liquid or pureed food without vomiting.
- You can walk without much pain.
Gastric Bypass Diet, Nutrition, Eating Plan
The postoperative diet plan consists of several steps. How long each stage lasts and what you can eat and drink will be determined by your healthcare professional or nutritionist. The importance of controlling your portions is emphasized at all stages. This habit will help you continue to lose weight and prepare you for how you will eat for the rest of your life.
1st process: liquid diet
In Stage 1, food intake is aimed at helping your body recover from surgery. Your diet will help you avoid postoperative complications.
For the first few days, you are only allowed to drink a few ounces of clear liquid at a time. It helps your stomach to heal without stretching from food.
2nd process: puréed diet
When the doctor decides that you are ready, you can proceed to step 2. This step consists of mashed foods that have a thick, pudding-like consistency.
Many foods can be chopped at home using a food processor, blender, or other device.
Hot spices can irritate your stomach, so avoid them entirely or try them once at a time. Avoid fruits and vegetables with lots of seeds, such as strawberries or kiwi. You should also avoid foods that are too fibrous to thin, such as broccoli and cauliflower.
3rd process: soft foods diet
For several weeks, you probably won’t eat anything other than mashed food. Once your doctor decides that you are ready, you can add soft, easy-to-chew foods to your diet.
4th process: solids diet
This is the last step in your simple post-op diet. Slow down. Introducing new foods too quickly can cause painful gas, bloating, heartburn, and dumping syndrome. Add one new food at a time. Wait a day before introducing another new food.
The goal of the fourth step is to bring back healthy food in small portions. It is still recommended to start with softer foods and gradually move to chewy and fibrous foods.
Monitor your protein intake and make sure you eat healthy vegetables as your main source of carbohydrates. Stay away from unwanted carbohydrates such as refined sugar, pasta, rice, bread, chips, etc. You can now reduce your daily meals to three small, nutrient-dense meals (protein and vegetable). Add protein shakes and don’t forget about essential vitamins and nutritional supplements. Your total calorie intake will eventually reach 1000 to 1500 calories per day, but don’t push it.
