Obesity Treatment in Dr. Gian Contreras

Dr. Gian Contreras leads a specialized bariatric surgery practice in Santo Domingo, Dominican Republic. The clinic focuses on surgical obesity treatments and general surgery support. It operates as a single-specialty center within the Torre Profesional Corazones Unidos.

Specialized Medical Team

Dr. Gian Contreras is a board-certified bariatric surgeon who manages the clinical pathway for every patient. He holds professional memberships in several major organizations:

• American Society for Bariatric and Metabolic Surgery (ASMBS)
• Dominican College of Surgeons (CDC)
• Dominican Medical Association (CMD)
• Dominican Association for the Study of Obesity (ASODEO)

Dr. Contreras completed his surgical training at Hospital Salvador B. Gautier. He then obtained specialized bariatric certification at Hospital Ángeles Tijuana in Mexico. He also holds a recertification in laparoscopic and bariatric surgery from Clínica Reyna Sofía in Colombia. A multidisciplinary team assists him with patient coordination and operating room logistics.

Bariatric Surgery Procedures

The clinic offers several surgical options for weight reduction. Each procedure follows a structured medical pathway.

Sleeve Gastrectomy involves removing approximately 60–80% of the stomach. This creates a slender gastric tube that limits food intake. The procedure also removes the portion of the stomach that produces ghrelin. With less of this hunger hormone, patients feel fuller sooner and experience reduced appetite. Hospital stays typically last 2 days. This method can lead to roughly 70% excess-weight loss.

The clinic also offers SADI-S – a single anastomosis duodeno-ileal bypass with sleeve gastrectomy. This procedure combines a gastric sleeve with a simplified intestinal bypass. During surgery, the small bowel length is typically fixed at 250 cm. This technique suits patients needing significant metabolic intervention.

Bypass SADI is a combined surgical option available at the clinic. Patients can lose 50–75% of their excess weight within one year. The surgical team evaluates each patient to determine which bypass or sleeve method fits their health profile.

Eligibility and Treatment Pathway

The practice uses specific medical criteria to identify surgery candidates. Patients must show that traditional diet and exercise have not worked for at least six months. The clinic accepts patients who meet these requirements:

• A BMI greater than 40
• A BMI greater than 35 with obesity-related health problems
• Commitment to permanent lifestyle changes

Treatment begins with an initial evaluation and a nutritionist consultation. Specialists work together to create a personalized plan for every patient. This approach addresses all health factors before surgery.

Support Services for Patients

Follow-up care is central to the clinic's obesity treatment program. The team provides specialized post-surgical monitoring to manage recovery. This focus on long-term care helps patients maintain their weight loss results.

Patients can join a virtual support group led by Dr. Contreras. This group provides guidance through each phase of the bariatric journey. The clinic team also coordinates care for international patients traveling to the Dominican Republic. All support helps patients understand the risks and benefits of their chosen procedure.
