Gastric bypass (known as Roux-en-Y) is considered the most precise procedure with the strongest long-term results. It combines two mechanisms simultaneously:

First: Reducing stomach size by creating a very small upper pouch.

Second: Reducing the body's absorption of calories and sugars by bypassing part of the small intestine.

Gastric bypass is not merely a weight-loss procedure — it is a "metabolic" operation that resets the body's hormones, making it the top choice for those suffering from severe obesity accompanied by diabetes or severe acid reflux.

Procedure Steps

With Dr. Abdulrahman Al-Sayigh's expertise in handling complex cases, the gastric bypass is performed using advanced laparoscopic techniques as follows:

  1. Creating the Gastric Pouch: A small portion of the top of the stomach is separated to become the new food receptor, helping you feel full quickly with minimal amounts.
  2. Rerouting the Intestine: The small intestine is connected directly to the new gastric pouch, bypassing most of the stomach and duodenum, which reduces absorption of fats and sugars.
  3. Laparoscopic Technique: The procedure is performed through very small holes, reducing the hospital stay (usually 24-48 hours) and ensuring faster tissue healing.
  4. Precision Checks: All surgical connections are verified using the latest technologies before the patient leaves the operating room to ensure maximum safety.

Advantages & Results

Why does Dr. Al-Sayigh prefer this procedure for certain cases?

  • Diabetes Remission: Studies have shown this procedure contributes to remission of type 2 diabetes in up to 80% of patients, with many returning to normal blood sugar levels immediately.
  • Permanent Solution for Acid Reflux: It is the optimal surgical treatment for those suffering from chronic heartburn and hiatal hernia.
  • Control of "Sugar Addiction": Thanks to the absorption-alteration mechanism, this procedure helps patients who struggle to resist sweets to control their appetite remarkably.
  • Weight Stability: It is distinguished by its very strong long-term results in preventing weight regain (more than 10 years).

Pre- and Post-Operative Instructions

Before Gastric Bypass:

  • Perform a thorough examination of the stomach and esophagus (the doctor may request a simple diagnostic endoscopy before surgery).
  • Follow a high-protein, low-carbohydrate diet 10 days before the appointment to reduce liver size and facilitate surgery.
  • Complete fasting (food and water) for 8 hours before surgery.

After Gastric Bypass (Your New Lifestyle):

  1. Strict Dietary Progression:
  • Phase 1 (Two weeks): Clear and full liquids only to ensure healing of surgical connections.
  • Phase 2 (Two weeks): Begin with pureed and very soft foods.
  • Phase 3: Return to normal food with complete focus on protein as a primary component.
  1. New Eating Behavior: Chew food very well and avoid drinking while eating — wait 30 minutes to prevent pressure on the small stomach.
  2. Lifelong Vitamins: Since the body now absorbs fewer nutrients, daily commitment to vitamins and minerals (B12, calcium, and iron) becomes a lifelong necessity to maintain health, hair, and energy.
  3. Fluid Intake: Make sure to drink water in small, continuous sips throughout the day (1.5-2 liters) to avoid dehydration.
  4. Avoid Carbonated Drinks and Sugars: Avoid carbonated beverages and concentrated sweets to prevent dizziness or dumping syndrome.
  5. Physical Activity: Start light walking as soon as you leave the hospital and gradually increase duration, avoiding heavy lifting for 6 weeks.
  6. Regular Follow-Up: Commit to follow-up appointments and periodic tests every 3-6 months to check vitamin and mineral levels.
