Types of Bariatric Surgery
Types of Bariatric Surgery
There are many ways to lose weight, but there is a procedure suitable for each person based on their health condition and many other factors. Weight loss usually takes a long time and often poses an obstacle for people who want to lose weight after many other failed attempts.

Gastric Sleeve
Gastric sleeve is one of the most common operations in the Arabian Gulf and the Middle East in general. The operation is relatively simple and safe for most people with few risks of complications. It involves removing a large part of the stomach, approximately 80%, leaving a small tube-shaped portion. Sleeve gastrectomy helps reduce the amount of food you can eat in one meal naturally, making you feel full faster. In addition, hunger hormones that are usually produced in your stomach decrease, which helps stabilize your metabolism, reduce your appetite, and automatically regulate blood sugar levels as a result of weight loss.
Operation Mechanism
The operation is performed under local anesthesia and takes one to two hours. The surgery begins with several small incisions in the abdomen, followed by the insertion of a precise endoscope ending with a camera in one of these incisions. The camera helps transmit the image to the screen in front of the doctor, then the surgeon inserts small tools through those other incisions to remove the large part of the stomach, leaving only a quarter of it in the form of a small tube. After that, the doctor stitches these small incisions so that they do not leave scar marks after healing. A person usually needs to stay in the hospital for two days until the doctor allows them to return home.
Advantages of Gastric Sleeve:
- You can eat various types of food naturally and safely, you just need to reduce the quantity
- Your desire to eat will decrease as a result of removing the upper part of the stomach, which is responsible for secreting hunger hormones
- Less chance of stomach ulcers, as stomach acids will decrease
Gastric Bypass
In gastric bypass surgery, surgeons create a small pouch in the upper part of the stomach, separating it from the lower part using surgical staples. Then the small intestine is divided and the new part is raised to connect to the stomach pouch. Thus, food will flow through the smaller stomach and the lower part of the small intestine. Gastric bypass is characterized by reducing the amount of food your stomach can hold as well as the amount of nutrients that the small intestine can absorb. The doctor recommends it when diet and exercise don't work, as well as when the obese patient is unable to control their appetite or if they are exposed to health problems due to excess weight such as high blood pressure, heart disease, type 2 diabetes, and other diseases.
Advantages of Gastric Bypass
- Gastric bypass helps you lose more weight than other operations in the long term
- Improves some problems associated with being overweight, such as: gastric reflux, heart disease, cholesterol, diabetes, and other diseases
- Enables you to reduce the amount of food you can eat and feel full faster
Classic Gastric Bypass
Classic gastric bypass is one of the operations that makes a difference in the patient's life if the specialist doctor's instructions are followed and a healthy lifestyle is maintained. The operation aims to eliminate morbid obesity by reducing the size of the stomach and shortening the intestines. The operation helps reduce food absorption from the intestines as the patient's food consumption decreases and their feeling of hunger decreases due to the removal of the ghrelin hormone. There are a number of patients who resort to classic gastric bypass after sleeve gastrectomy, due to not reaching the desired weight after the operation or in case of any complications resulting from the wrong choice of operation. The patient usually starts getting results after 3 months and gets rid of the side effects of the previous sleeve operation if they faced any complications.
Classic Gastric Bypass Procedure
An upper pouch is made at the top of the stomach and separated from the rest of the stomach using modern staplers, which reduces the stomach to 20%. Then the small intestine is connected to the pouch and then the intestines are connected to the intestines. Dr. Abdulrahman is keen to take all the procedures that precede the operation and diagnose the case to choose the most suitable operation for the patient.
Advantages of Classic Gastric Bypass
- Loss of more than 70% of excess weight within a year
- Reduction of symptoms of diseases associated with obese patients, such as: type 2 diabetes, and improvement has been observed in type 1 diabetes patients
- The operation is characterized by its ability to be modified, where the stomach can be returned to its normal state
Mini Gastric Bypass
Mini gastric bypass is one of the most successful operations. The operation performed using advanced surgical endoscopes includes two main parts, as it involves reducing the stomach by isolating approximately 65% to 85% of the stomach size and isolating approximately 20% to 40% of the intestinal length. This is done by inserting small tools through small openings in the upper part of the abdominal wall. In the mini gastric bypass operation, the non-isolated part of the stomach is connected to the intestines. Reducing the size of the stomach limits the amount of food consumed, which makes the patient feel full quickly. The intestines' absorption of sugars and starches also decreases, which helps prevent weight gain even when eating high-calorie foods.
Advantages of Mini Gastric Bypass
- Loss of approximately 70% of excess weight within a year
- Improving the patient's health status and reducing the severity of diseases associated with obesity
- Faster recovery and less pain due to using the endoscope through small incisions
Revision Bariatric Surgery
Revision surgery is resorted to after the patient has undergone one of the bariatric surgeries previously, but the operation performed did not achieve the desired results or perhaps the patient suffered from one of the complications after surgery. Performing revision bariatric surgery usually depends on medical evaluation by the specialist doctor to assess your health status and know the reasons that require revision surgery.
Most Famous Obesity Revision Procedures:
- Operation to restore the normal shape of the stomach and digestive system, and cancel all the steps that were taken in the first operation
- Modification of bariatric surgery steps
- Changing the type of operation to another form of bariatric surgery, such as: changing gastric banding to gastric bypass
Reasons for Resorting to Revision Operations
- Poor choice of surgeon
- Weight regain
- Stomach expansion due to non-compliance with doctor's instructions
- Wrong choice of the most suitable type of operation for the patient

Obesity Diseases
Diagnosis of Obesity Diseases
Before any obesity surgery is performed, Dr. Abdulrahman evaluates the patient's health status and performs all necessary examinations and preparations that precede the operation, to ensure they get satisfactory results that achieve patient satisfaction and rid them of the problems they face. These are the most important benefits of obesity surgery:

Significant and Sustainable Weight Loss
Bariatric surgeries have proven their effectiveness in the long term for class III obesity, as they have contributed to achieving permanent weight loss.

Reducing Hunger Hormones and Improving Metabolism
Reprograms the body's metabolism after obesity, which prevents weight regain.

Improving Cholesterol and Blood Sugar Levels
Bariatric surgery alleviates symptoms of type 2 diabetes and improves the cumulative rate. But most importantly, continuous follow-up to maintain the operation result.


Improving Physical Activity
Losing excess weight helps you become lighter in movement, which leads to improved ability to perform physical activities more easily.

Improving Sleep Quality
The majority of obese people have sleep apnea problems, so bariatric surgeries can effectively alleviate symptoms of sleep apnea and get better sleep.

Reduces Your Desire to Eat
Bariatric surgeries reduce the amount of food you can eat, thus consuming fewer calories and losing weight faster.
