An Effective, Time-Tested Solution for Severe Obesity

Gastric bypass surgery — also known as Roux-en-Y gastric bypass — is a powerful bariatric procedure that combines restriction and malabsorption to produce significant, long-term weight loss. Gastric bypass is one of the three obesity surgery procedures offered at Dr. Cinik Hospital in Istanbul. Here, this surgery is performed using the latest laparoscopic techniques, which ensures safety, reduced pain, and a faster recovery.

If you’re struggling with obesity and related health issues such as type 2 diabetes, high blood pressure, or metabolic syndrome, gastric bypass in Turkey may be the comprehensive solution you’ve been long searching for.

What Is Gastric Bypass Surgery?

Gastric bypass surgery involves two main changes:

  1. A small stomach pouch is created (roughly the size of a walnut), reducing the amount of food you can eat at one time.
  2. The small intestine is rerouted to bypass a portion of the digestive tract, which limits calorie and nutrient absorption.

Together, these changes lead to rapid and sustainable weight loss, hormonal balance, and improvement or remission of obesity-related condition

Who Should Consider Gastric Bypass?

Gastric bypass may be recommended if:

  • You have a BMI of 40 or higher, or BMI of 35+ with related conditions
  • You suffer from severe type 2 diabetes, insulin resistance, or GERD
  • You have failed to achieve lasting weight loss with lifestyle changes alone
  • You are committed to making lifelong dietary adjustments
  • You are between 18 and 65 years of age, physically and mentally prepared for surgery

This procedure may be especially beneficial for individuals with poorly controlled diabetes, as it can enhance insulin sensitivity and promote remission.

Step-by-Step: How Gastric Bypass Surgery Works?

Here’s what your treatment journey will look like:

1. Pre-Travel Requirements

Before your arrival in Turkey, you’ll need to provide results of:

  • C-peptide test
  • Hemoglobin A1c test

These tests evaluate your blood sugar control and pancreatic function, essential for planning bypass surgery, especially in diabetic patients.

2. Arrival and Hospitalization

You’ll arrive in Istanbul (our representative will meet you and help with transfer to the hotel, if necessary) and be admitted to the hospital the night before your surgery. A member of our international team will help you with check-in, translation, and hospital orientation.

3. Pre-Operative Workup

On your first day, you’ll undergo:

  • Full blood panel and imaging
  • Anesthesia clearance
  • Psychological and dietary assessments

4. Surgery Day

  • The operation is performed under general anesthesia
  • Duration: approx. 90–120 minutes
  • Entirely laparoscopic (keyhole incisions)
  • Both stomach pouch creation and intestinal rerouting are completed

5. Recovery and Stay

  • 3 nights in hospital for monitoring, pain management, and early mobility
  • 2 nights in a hotel with continued support
  • Return home on Day 5 post-surgery

What to Expect After Surgery

Gastric bypass produces faster and more pronounced weight loss compared to other bariatric procedures. Most patients lose from 60 to 80% of excess body weight within 12–18 months. In addition:

  • Type 2 diabetes often goes into remission within weeks
  • Blood pressure, cholesterol, and joint problems typically improve
  • Appetite is reduced due to hormonal changes

Long-term success depends on following a post-surgical diet, exercise, and supplementation pla

Risks and Complications

While gastric bypass is safe when performed by skilled surgeons, it is more complex than gastric sleeve surgery and carries some specific risks:

  • Anastomotic leaks or strictures
  • Dumping syndrome (rapid gastric emptying after eating sugar-rich foods)
  • Nutritional deficiencies (iron, B12, calcium)
  • Ulcers at the connection points
  • Internal hernias

We provide detailed post-op instructions and ongoing guidance to help minimize risks and support recovery.

What’s Required from the Patient?

The patient’s behavior before and after surgery plays a crucial role in long-term success. So, every patient should be ready to:

  • Commit to long-term lifestyle changes
  • Follow pre-op fasting and medication instructions
  • Quit smoking at least 2 weeks prior
  • Stick to the post-op four-phase diet
  • Take prescribed vitamins to avoid deficiencies
  • Attend follow-up dietitian consultations remotely if needed

Is Gastric Bypass Right for You?

This procedure may be more appropriate than gastric sleeve if you have:

  • Long-standing or insulin-dependent diabetes
  • Chronic acid reflux (GERD)
  • A higher BMI or rapid weight loss goals
  • Failed outcomes from previous bariatric procedures

Our medical team will advise on the best procedure for your individual condition.

Optional Post-Weight Loss Surgery

As your body transforms, you may choose to address excess skin or aesthetic concerns. Dr. Cinik’s hospital offers body contouring surgeries such as abdominoplasty (tummy tuck), breast lift, or arm lift. This procedure will be ideal after major weight loss and stabilization.

Gastric Bypass Surgery FAQ

What’s the difference between gastric bypass and gastric sleeve?

Gastric bypass both reduces stomach size and reroutes the intestines to limit absorption, while gastric sleeve only reduces stomach volume. Bypass may result in faster weight loss and better control of diabetes, but involves a slightly higher risk of nutritional deficiencies.

Will I be able to eat normally again?

Yes, but in much smaller amounts. You will go through certain diet phases — liquid food, then pureed, soft, and, finally, solid. You’ll eventually enjoy a wide range of foods in smaller portions, but must avoid sugar-heavy and fatty meals to prevent dumping syndrome.

Is the weight loss permanent?

Yes, if supported by a healthy lifestyle afterwards. However, without proper dietary control and exercise, weight regain is possible after any bariatric surgery.

Do I need to take supplements forever?

Most patients need lifelong supplementation with multivitamins, iron, calcium, and vitamin B12 to prevent deficiencies due to reduced nutrient absorption.

How soon will I see improvements in my diabetes?

In many cases, blood sugar control improves dramatically within days after surgery — often before significant weight loss occurs.

Can this be reversed if needed?

Gastric bypass is considered a permanent procedure. While technically reversible, reversal is complex and rarely performed unless medically necessary.
