Bariatric Surgery in Mexicali for U.S. Patients

Weight-loss surgery just across the border

For many patients in the U.S. Southwest, quality bariatric care is closer than they think. Mexicali sits directly across the border from Calexico, California, making it one of the most accessible destinations for weight-loss surgery for patients from Arizona, California and New Mexico. Instead of a long international trip, many patients reach Baja Surgeons Hospital within a short drive of the crossing.

What matters in this decision is not distance alone, but who performs the surgery, where, and with what follow-up. This page is meant to help you evaluate those factors clearly.

Why patients choose Dr. Calderón

Dr. Calderón is a general and bariatric surgeon who combines scientific rigor with a clear, patient-centered approach — explaining what your options are, what to expect at each stage, and what a realistic outcome looks like. His practice emphasizes education over pressure, so you can make an informed decision.

Care is delivered by a bilingual team, which removes one of the biggest sources of anxiety for cross-border patients: being understood, and understanding your own care plan.

Choosing the right procedure

Gastric sleeve (sleeve gastrectomy) is a laparoscopic procedure that reduces stomach size to lower appetite and support durable weight loss, with average excess-weight loss near 59% at five years or more and improvement of obesity-related conditions.

Gastric bypass (Roux-en-Y) is a reference bariatric procedure, especially considered in severe obesity and in the control of type 2 diabetes, with sustained weight loss beyond 15 years and lifelong supplementation. The gastric balloon is a temporary, non-surgical option for selected patients, and metabolic surgery targets type 2 diabetes in patients with obesity.

The right procedure depends on your BMI, comorbidities and goals, and is decided in a medical consultation — not chosen from a menu.

Accreditation and safety

Procedures are performed at Baja Surgeons Hospital in Mexicali, with anesthesiology and inpatient care on site. For U.S. patients, hospital accreditation and the surgeon's credentials are the two anchors of trust, so both are presented transparently.

Every surgery carries risks, which Dr. Calderón discusses directly and without guarantees of results. A proper evaluation, clear pre- and post-operative instructions, and structured follow-up are part of a safe process.

Cost, insurance and HSA/FSA

Many U.S. patients ask about cost first. Per Mexican health-advertising regulations, a fixed price is not published on this site; your exact cost is confirmed in your consultation, where financing options are also reviewed.

Some patients use HSA or FSA funds toward eligible medical expenses — check your plan's rules, as coverage for care abroad varies.

Planning your trip

Because Mexicali borders Calexico, travel logistics are simpler than for most medical-tourism destinations. In your consultation, the team reviews the recommended length of stay, the recovery timeline before traveling back, and what to arrange for your return.
