One Anastomosis/Mini Gastric Bypass In Dubai

Mini Gastric Bypass (MGB) in Dubai, alternatively known as one anastomosis, is a surgical weight loss procedure which helps individuals achieve significant and sustainable weight loss. 

In this, the surgeon creates a smaller stomach pouch by sewing or stapling part of the stomach, connecting it to the small intestine- bypassing the major portion of the stomach and the digestive tract. This procedure results in reduced food intake and limited absorption of calories. 

MGB is considered a less invasive alternative to traditional gastric bypass surgery, offering effective weight loss with potentially fewer complications. Mini Gastric Bypass Dubai is gaining popularity as a solution for those struggling with obesity, providing a pathway to better health and improved life.


What is the difference between the Gastric and Mini Gastric Bypass procedures?

The main difference between Gastric Bypass and Mini Gastric Bypass lies in the surgical approach and anatomy alterations. In a Gastric Bypass, the stomach is divided into a small upper pouch, and the small intestine is rearranged to connect to this pouch. 

Mini Gastric Bypass simplifies the process by creating a longer, tubular stomach pouch and connecting it to a lower portion of the small intestine (with one joint anastomosis). Mini Gastric Bypass is less complex and time-consuming than traditional Gastric Bypass, potentially resulting in a shorter surgery with similar weight loss outcomes. 

However, both procedures aim to limit food intake and nutrient absorption to promote weight loss in individuals struggling with obesity. 

Who is recommended this surgery?

The surgery “ Mini Gastric Bypass Dubai” is recommended for individuals with serious health issues linked to morbid obesity, including uncontrolled diabetes and hypercholesterolemia. Dr. Balaji advises this operation for patients with a BMI of 50 or higher, presenting obesity-related health problems, and those committed to adopting a healthier lifestyle. It is also a backup operation if a traditional gastric bypass can not be performed due to difficulty or anatomical challenges.  It is also sometimes offered as a second-stage of a two-stage procedure following a sleeve gastrectomy for inadequate weight loss.

Benefits & Potential Results

Similar to gastric bypass surgery in Dubai, mini gastric bypass surgery offers an effective, long-term weight loss solution. Studies indicate a potential loss of approximately 30% of excess weight within the first year after surgery. Moreover, it may improve or reverse obesity-related health conditions such as diabetes, hypertension, hyperlipidemia, heart diseases, sleep apnea, osteoarticular diseases, and infertility.  However it is to be noted that there is a small chance of reflux/bile reflux which may get worse after surgery and may need conversion to a standard gastric bypass.

What’s Involved In “Mini Gastric Bypass”?

Before Surgery

Before undergoing surgery, Dr. Balaji may require lab tests and information about your regular medications. Certain medications, especially blood-thinning, hypertension, or diabetes medications, may have restrictions leading up to the procedure.

During Surgery

Dr. Balaji performs Mini Gastric Bypass using a laparoscopic approach. Small incisions are made in the abdomen, and a laparoscopic instrument is used to create a small stomach pouch. A portion of the intestine is cut and sewn directly into the stomach pouch.

Food passes directly to the intestine, avoiding the absorption of fat and carbohydrates.

The procedure is conducted under general anaesthesia, and patients are closely monitored for any complications. The entire procedure takes a few hours.

After Surgery

  • Recovery Period: Typically, 3-6 weeks are needed for full recovery, with caution needed when resuming regular activities.
  • Diet Transition: Gradual transition from liquids to solids post-surgery.
  • Hospitalization: Patients may stay in the hospital for one day after the procedure.
  • Supplements: Vitamin and mineral supplements are recommended to prevent malnutrition.

While the procedure is generally safe, there may be some potential risks associated with Mini Gastric Bypass in Dubai. One possible aftereffect may be bile reflux, which may occur when gallbladder content moves into the stomach. However, there is no conclusive evidence linking it to carcinogenic effects. Micronutrient supplements might be necessary due to malabsorption.  A small number of people get excess weight loss and may need further supplementation or rarely further surgery.

 Recovery generally takes 3-6 weeks, with caution needed to resume regular activities.

  It was advised to avoid pregnancy for up to 1-½ years after surgery.  

Yes, patients often experience a significant reduction in health issues associated with obesity, including high blood pressure, asthma, heart disease, diabetes, osteoarthritis, gout, obstructive sleep apnea, and depression. 

Although technically possible,  Mini Gastric Bypass is generally considered irreversible due to the structural changes made to the digestive system. However it may be converted to a standard gastric bypass for intractable reflux.
