High-BMI patients
Specialised expertise in patients with a BMI over 50 — where the anatomy demands adapted surgical technique and considerably more pre-operative preparation than a standard case.
More than fifteen years in bariatric surgery and over 8,000 surgical procedures — with a practice built around the two groups other surgeons most often turn away: patients with a very high BMI, and patients whose first weight-loss surgery didn’t work.
Written for the patients who came to him at Pompeii Surgical. We’ve kept it as he wrote it.
“With over 15 years of experience in bariatric surgery, I have dedicated my career to helping patients achieve their weight loss goals, particularly those facing unique challenges.”
“Every patient deserves a chance at a healthier life, regardless of their starting point or previous surgical history.”
“My commitment extends beyond the operating room. I work closely with patients throughout their entire journey, from initial consultation through recovery and long-term follow-up care.”
Two of these are the cases patients most often struggle to find a surgeon for at all.

Corrective and conversion procedures for patients who have already had bariatric surgery elsewhere and need it put right. See revision surgery at Pompeii.
Experience managing patients carrying multiple comorbidities at once — diabetes, heart disease, sleep apnoea — where the surgery is only part of the problem to solve.
For high-BMI patients he took extra time before surgery: working with the nutritionist, managing comorbidities, and building a plan around that patient’s specific anatomy.
His approach to revision started with why the previous procedure didn’t deliver — then built a plan addressing those specific reasons while minimising added risk.
He kept current with advances in bariatric technique through ongoing professional development, on the view that a surgeon who stops learning hands the risk to their patients.
Thorough preparation, meticulous surgical technique and comprehensive follow-up were, in his own framing, the three things that decide outcomes — and the harder the case, the more each one matters.
Revision surgery in particular he treated as its own discipline rather than a repeat of a primary operation. The anatomy has already been altered once; the surgeon is working with someone else’s decisions and a patient who has already been let down once.
He worked alongside a wider team — nutritional counselling, psychological support, ongoing medical management — and encouraged patients to ask questions and take an active part in their own care.
Dr. Jesus Grimaldi — also written Doctor Grimaldi — is a board certified bariatric surgeon with more than 15 years in practice and over 8,000 surgical procedures performed. He specialised in high-BMI patients and revision bariatric surgery, and operated as a bariatric surgeon with Pompeii Surgical in Tijuana, Baja California.
Patients with a BMI over 50 need different surgical planning: more pre-operative optimisation, adapted technique for the anatomy, and closer management of conditions like diabetes, heart disease and sleep apnoea. Many centres decline these cases outright. Dr. Grimaldi’s practice concentrated on exactly them.
Revision surgery corrects or converts a previous bariatric procedure that didn’t achieve the intended result, or that caused problems. It’s a different discipline from a first-time operation — the surgeon works with anatomy that has already been altered, and has to understand why the original fell short. Pompeii performs revisions from $5,800; see revision surgery.

Higher-BMI patients and revision cases are among the most common reasons people are declined. They’re also among the things Pompeii does most. Approval is free and nothing is due before you reach the hospital.
