Reduction in Cardiometabolic Disease Risk Following Gastric Bypass Surgery Among Hispanic Adults

• This study found that bariatric surgery significantly reduced the risk of serious heart and metabolic health problems — including type 2 diabetes, high blood pressure, high cholesterol, and metabolic syndrome — specifically among Hispanic adults. The benefits went well beyond weight loss alone.
• Hispanic adults in the United States face higher rates of type 2 diabetes, metabolic syndrome, and cardiovascular disease compared with the general population. This study provided important evidence that bariatric surgery is highly effective at improving these conditions in Hispanic patients specifically.
• The improvements in diabetes were particularly notable. Improvements in blood pressure and cholesterol were also significant, reducing the overall risk of heart disease and stroke.
• Dr. de la Cruz-Muñoz led this research as the first author, reflecting his commitment to studying outcomes in the community he serves. His practice in Miami treats a predominantly Hispanic patient population, and this study demonstrates that he has specifically researched and published on how bariatric surgery benefits Hispanic patients.
• For patients in the Miami area who are managing diabetes, high blood pressure, or high cholesterol alongside obesity, this study shows that bariatric surgery can address multiple health conditions at once — not just help with weight loss, but meaningfully improve the metabolic and cardiovascular health problems that often accompany severe obesity.

Why This Study Was Needed

Hispanic adults face high rates of obesity, diabetes and heart disease, but there was little information on how much bariatric surgery reduces their cardiometabolic risk, especially in Hispanic patients who are not Mexican American.

How the Study Was Done

The team reviewed 633 Hispanic adults from Central and South America and the Caribbean who had gastric bypass with Dr. de la Cruz-Muñoz’s program from 2002 to 2010. Weight, BMI, blood pressure, fasting glucose, HbA1c and cholesterol levels were compared before and one year after surgery.

What the Study Found

• Average weight fell from 127 to 109 kg and BMI from 46.4 to 39.9.
• Every cardiometabolic risk factor improved: systolic and diastolic blood pressure, fasting glucose, HbA1c, HDL, LDL, total cholesterol and triglycerides.
• Men had greater improvements in weight (21.7 vs 16.9 kg), HbA1c, HDL and triglycerides.
• Women had a greater improvement in LDL cholesterol.

What This Means for Patients

Gastric bypass reduces the cluster of risk factors known as metabolic syndrome, which drives heart disease. For Hispanic patients, this study provides direct evidence from people like them. See What Happens to Your Health Conditions After Bariatric Surgery.

Clinical Pearls

• All measured cardiometabolic risk factors improved one year after gastric bypass in Hispanic adults.
• Improvements differed by sex.
• Results apply to Hispanic patients of Caribbean, Central and South American origin.

Strengths and Limitations

A large, well-defined Hispanic cohort strengthens the findings. The study is retrospective and limited to one year.

Expert Commentary

My patients come from across Latin America and the Caribbean, and for years the research did not reflect them. This study showed that their heart risk improves dramatically after gastric bypass, which is exactly what I see in clinic.
