Gastric Sleeve Surgery (Bariatric Surgery) for Weight Loss

Obesity is more than just a cosmetic concern—it’s a serious medical condition that increases the risk of other health problems such as heart disease, diabetes, high blood pressure, and certain cancers. When lifestyle changes such as diet and exercise are not enough to help with weight loss, bariatric surgery—specifically gastric sleeve surgery or sleeve gastrectomy—can be a life-changing option. Vibhavadi Hospital offers comprehensive care for patients seeking long-term weight loss solutions through this safe and effective surgical method.

Understanding Gastric Sleeve Surgery

What is Gastric Sleeve Surgery?

Gastric sleeve surgery, also known as sleeve gastrectomy or "เย็บกระเพาะลดความอ้วน" in Thai, is a type of bariatric surgery designed to aid in significant weight loss. This procedure involves removing approximately 75–80% of the stomach, leaving a narrow, sleeve-shaped tube. The reduction in stomach size limits food intake and affects hunger-related hormones, contributing to weight loss.

How It Works

The surgery works through two primary mechanisms:

Restriction: The smaller stomach can hold less food, which helps reduce caloric intake.
Hormonal Changes: The surgery alters hormones such as ghrelin (the “hunger hormone”), which plays a role in appetite, metabolism, and blood sugar control.

Who is a Candidate for Gastric Sleeve Surgery?

Eligibility Criteria

Gastric sleeve surgery is recommended for individuals who:

Have a Body Mass Index (BMI) ≥ 40, or
Have a BMI ≥ 35 with at least one obesity-related health condition such as type 2 diabetes, high blood pressure, or sleep apnea
Have unsuccessfully attempted weight loss through traditional methods
Are committed to long-term lifestyle changes post-surgery

Not Suitable For Everyone

The surgery may not be ideal for individuals with:

Certain gastrointestinal conditions
Severe heart or lung problems
Mental health disorders that may affect post-surgical behavior
Pregnancy or plans to conceive shortly after surgery

Health Risks of Untreated Obesity

If left unaddressed, obesity can lead to:

Type 2 diabetes
Cardiovascular disease
Stroke
Osteoarthritis
Sleep apnea
Fatty liver disease
Certain cancers

By addressing obesity early with the help of specialists, patients can reduce or even eliminate many of these risks.

The Gastric Sleeve Surgery Procedure

Before the Surgery

Patients undergo a comprehensive evaluation which includes:

Nutritional and psychological assessments
Blood tests and imaging
Consultations with a multidisciplinary medical team

Lifestyle changes such as dietary adjustments, quitting smoking, and moderate physical activity are encouraged pre-operatively.

During the Surgery

The surgery is performed laparoscopically under general anesthesia
Small incisions are made, and surgical instruments are used to remove part of the stomach
No foreign devices are implanted
The procedure typically takes 1–2 hours

After the Surgery

Hospital stay: Usually 2–3 days
Recovery: Most patients return to normal activities within 2–4 weeks
Diet: Progression from liquids to pureed and then soft foods over several weeks
Weight loss: Most patients lose 50–70% of excess weight within the first year

Benefits of Gastric Sleeve Surgery

Significant long-term weight loss
Improvement or resolution of obesity-related conditions (diabetes, hypertension)
Increased energy and mobility
Enhanced quality of life
Reduced risk of mortality from obesity-related diseases

Risks and Complications

While the procedure is generally safe, it carries potential risks, including:

Infection or bleeding
Leaks from the stapled stomach
Nutritional deficiencies

Blood clots

These risks are minimized when performed by experienced surgical teams with comprehensive aftercare support.

Frequently Asked Questions (FAQ)

Is gastric sleeve surgery reversible?
No. Unlike adjustable gastric banding, this procedure is irreversible as part of the stomach is permanently removed.

Will I need to take supplements after surgery?
Yes. Patients are advised to take multivitamins, calcium, vitamin B12, and iron to prevent deficiencies.

How much weight will I lose?
Most patients lose 50–70% of their excess weight within 12–18 months, depending on adherence to lifestyle changes.

Can I get pregnant after surgery?
Yes, but it's recommended to wait at least 12–18 months before conceiving to ensure stable weight and nutritional health.

Is it safe for older adults?
While age is a factor, the procedure can be safely performed on older individuals following a thorough pre-operative assessment.
