About Dr. García López
Dr. Ernesto García López is a highly experienced bariatric and metabolic surgeon at Hospital Ángeles Tijuana — one of the most respected private hospitals in northwest Mexico and a leading destination for medical tourism from the United States and Canada. With 15 years of specialized practice in bariatric surgery, Dr. García López has performed over 3,500 bariatric procedures, establishing himself as one of the most sought-after weight loss surgeons serving the US-Mexico border region.
Tijuana's proximity to San Diego, California — just minutes from the international border crossing — makes it an exceptionally accessible destination for patients from California, Arizona, and across the western United States who seek high-quality bariatric surgery at a fraction of the cost of US-based procedures. Hospital Ángeles Tijuana is a fully accredited facility with modern operating theaters, advanced laparoscopic equipment, and a bilingual medical staff, ensuring that English-speaking patients receive care in a familiar, comfortable clinical environment.
Dr. García López's surgical philosophy prioritizes patient safety above all else. He performs a meticulous pre-operative assessment for every bariatric candidate, including cardiopulmonary evaluation, psychological readiness assessment, nutritional counselling, and endoscopic upper GI evaluation, to ensure each patient is optimally prepared for surgery. His program incorporates a comprehensive pre-operative and post-operative support structure including dietitians, psychologists, and exercise specialists.
Fluent in both Spanish and English, Dr. García López is equally comfortable serving Mexican patients and international patients from the United States and beyond. He is a firm believer that bariatric surgery is not a quick fix but a powerful tool that, combined with lifelong nutritional and lifestyle commitment, delivers transformative and durable results.
Education & Training
Dr. García López completed his medical degree (Médico Cirujano) at the Universidad Autónoma de Baja California (UABC) before completing his specialty in General Surgery (Cirugía General) at the Hospital General de Tijuana — a high-volume public hospital providing rigorous surgical training. During his general surgery residency, he developed a strong foundation in laparoscopic techniques and minimally invasive abdominal surgery.
Following general surgery certification, Dr. García López completed a dedicated bariatric and metabolic surgery fellowship, training with experienced bariatric surgeons in Mexico City and undertaking additional training at accredited bariatric centers in the United States. This training equipped him with comprehensive proficiency in sleeve gastrectomy, Roux-en-Y gastric bypass, mini gastric bypass, and revisional bariatric surgery.
He holds specialist certification from the Consejo Mexicano de Cirugía General and is a certified member of the Sociedad Mexicana de Cirugía de la Obesidad y Enfermedades Metabólicas (SMCOEM) — Mexico's national body for bariatric surgery standards and certification. He is also an active member of the American Society for Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity (IFSO).
Clinical Expertise & Procedures
Dr. García López's primary surgical expertise is in laparoscopic bariatric and metabolic procedures. He performs laparoscopic sleeve gastrectomy (LSG) — currently the most commonly performed bariatric procedure worldwide — with a technique that emphasizes standardized staple line reinforcement, careful bougie sizing, and meticulous hemostasis to minimize leak and bleeding risk.
For patients requiring greater metabolic impact, particularly those with poorly controlled type 2 diabetes, he performs laparoscopic Roux-en-Y gastric bypass (RYGB) and mini gastric bypass (MGB). He is also experienced in the duodenal switch procedure for super-obese patients and in revisional bariatric surgery for patients who have had inadequate weight loss or complications from prior bariatric procedures.
Dr. García López has particular expertise in metabolic surgery for type 2 diabetes — recognizing that for eligible patients, bariatric surgery can achieve diabetes remission in a way that no medication can match. Conditions he regularly treats include morbid obesity (BMI > 40 kg/m²), obesity with type 2 diabetes, hypertension, obstructive sleep apnea, dyslipidemia, metabolic syndrome, and obesity-related osteoarthritis.
Research & Publications
Dr. García López's work is primarily grounded in clinical practice and high-volume surgical experience, reflecting the practice model at Hospital Ángeles Tijuana where clinical excellence and patient outcomes are the primary focus. He has contributed case series and outcome reports on sleeve gastrectomy and gastric bypass results in Mexican patients to regional and national surgical conferences.
He participates in the SMCOEM national bariatric surgery outcomes registry, contributing data that supports Mexico-wide analysis of bariatric safety and efficacy. He has presented clinical outcomes data at the annual Congreso Nacional de Cirugía de la Obesidad and at regional surgical meetings in Baja California.
Dr. García López regularly attends the ASMBS Annual Meeting and IFSO World Congress to remain current with the latest evidence on bariatric techniques, long-term outcomes research, and emerging metabolic surgery indications. He applies international evidence-based protocols — including those from the ASMBS Clinical Issues and Guidelines committee — to his practice at Hospital Ángeles Tijuana.
International Patient Services
Dr. García López and Hospital Ángeles Tijuana have extensive experience serving international patients — particularly from the United States and Canada — who choose Tijuana for bariatric surgery due to the significant cost advantage (often 50–70% less than equivalent US procedures) and the hospital's convenient location steps from the US-Mexico border.
He offers pre-operative telemedicine video consultations in both Spanish and English, during which he reviews the patient's medical history, BMI, comorbidities, and prior surgical history to assess candidacy for bariatric surgery and recommend the most appropriate procedure. For US-based patients, the care pathway typically involves a telemedicine consultation, completion of pre-operative labs and studies near the patient's home, followed by travel to Tijuana for a same-day or next-day procedure with a 2–3 night hospital stay.
Hospital Ángeles Tijuana provides English-speaking nursing and patient relations staff, and Dr. García López conducts post-operative consultations and follow-up in English via telemedicine for international patients who have returned home. He provides a complete surgical report, dietary guidelines, and follow-up protocol documents tailored for handoff to the patient's primary care physician in their home country.
