Mini Gastric Bypass / Omega Loop Surgery in Dubai

What Is A Mini Gastric Bypass?

Mini Gastric Bypass, also known as an ‘Omega Loop Bypass’ is a recent and revolutionary weight-loss surgery. This technique involves the creation of a lesser gastric pouch connected to a shorter intestine loop.

The Mini Gastric Bypass procedure is available as part of  the King’s Weight Loss & Bariatric Programme, that includes an optional 6 month support package post surgery, to ensure you have the best opportunity to reach your weight loss goals.

Why Is the Surgery Done?

The mini gastric bypass is usually done to treat morbid obesity by creating a new malabsorption canal to restrict the amount of fat and calories absorbed from your diet. Typically, the procedure is applied in order to reduce the risk of potentially life-threatening weight-related health problems.

Who Is the Surgery Recommended For?

A mini gastric bypass is recommended for patients with serious health problems related to morbid obesity such as uncontrolled diabetes and hypercholesterolemia. This operation is not recommended for patients with BMI less than 45.  Summary of conditions patients should satisfy before being recommended this surgery include:

  • BMI of 45 or higher.
  • Obesity-associated serious health problems.
  • No history of gastrointestinal diseases.
  • Commit to healthy lifestyle changes.

Benefits & Potential Results

As with other weight-loss surgeries, the mini gastric bypass procedure can be a very effective long-term way to lose weight, depending on how much you change your lifestyle habits. Studies have shown that patients can lose approximately 30% of their excess weight within the first year after surgery.

Additionally, it may also improve or even reverse some health conditions related to being overweight, including:

  • Diabetes
  • Hypertension
  • Hyperlipidemia
  • Heart diseases
  • Sleep apnea
  • Osteoarticular diseases
  • Infertility


Due to the bypass configuration, it’s possible to have bile reflux, which is the movement of the gallbladder content into your stomach. In the long-term, this could be related to carcinogenic effects. However, so far, no evidence of this problem has been proved.

Micronutrient supplements may be required because of the malabsorption created.

Before Surgery

In order to be selected as a valid candidate for the procedure, your doctor might require some lab tests. Also, you need to inform them about your regular medication (blood-thinning, hypertension or diabetes medication) since there will be some restrictions on which you can take, as well as what you can eat and drink before the procedure.

During Surgery

Mini gastric bypass is performed is most cases through a laparoscopic technique. The procedure involves the following steps:

  • After making several small incisions in your abdomen, the surgeon will insert the laparoscopic instruments and cut across a lesser longitudinal portion of your stomach and make a small pouch.
  • A small part of your intestine is cut and sewed directly into the stomach pouch.
  • Food will now pass directly to your intestine, avoiding the absorption of fat and carbohydrates.

During the procedure, you will be sleeping under general anesthesia and monitored closely for any complication. The whole procedure will take a few hours.

After Surgery

Immediately after the procedure, you won’t be allowed to eat or drink for about 8 hours. After that, your diet will be gradually changing over liquid to solid and the amount of food you can take will be changing as well. Since mini gastric bypass is major surgery, you might be at the hospital at least 3-5 days.  Also, your doctor will recommend you take vitamin and mineral supplements after your surgery in order to avoid malnutrition.

Both mini gastric bypass, also known as omega loop, and conventional gastric bypass procedures are quite efficient for weight loss. Nevertheless, the latter is technically complex and poses a 6% drawback risk.  Mini-gastric bypass surgery is a comparatively easier lower-risk bariatric procedure, which reduces the possibility of a “staple leak.” This is because it simply requires one anastomosis, unlike roux-en-y, which requires two new connections.

To get mini gastric bypass surgery, patients should have a 35-40 Body Mass Index (BMI) and no track record of gastroesophageal reflux disease (GERD). If you have reflux disease, you could be a viable pick for standard bypass surgery instead. In addition, if repeated attempts to lose weight through diet and exercise yielded no results you could be a potential candidate.

The surgical treatment carries an array of concerns. The major ones include dehydration, hypoglycemia, gallstones, kidney stones, and the most common one, mineral and vitamin deficiency. Even so, obtaining the advice and assistance of a competent surgeon nearly eliminates the possibility of experiencing these problems.

If you want to get pregnant after surgery, you should wait roughly 3 months. This reduces the likelihood of experiencing complications during labor, such as eclampsia, macrosomia, and gestational diabetes. Furthermore, you will also have a lower risk of having a stillbirth or miscarriage compared to women who are overweight and have not had the operation.

Yes, it will. You will notice a considerable reduction in health issues associated with obesity, such as high blood pressure, asthma, heart disease, diabetes, osteoarthritis, gout, obstructive sleep apnea, and depression, along with many other ailments.

Considering the omega loop operation is performed under anesthesia, your body would require additional time to recuperate, which typically takes 3-6 weeks. After the procedure, swallowing meals may be problematic, therefore limit yourself to liquids for the initial two weeks. Be particularly cautious at this time; wait a few days following your operation to resume typical routines such as driving and avoid lifting heavy objects and vigorous workouts.
