Hispanic and Latino Americans develop type 2 diabetes at roughly twice the rate of non-Hispanic white Americans, and the reasons go beyond diet and exercise. A combination of genetic factors, socioeconomic barriers, and lower rates of early screening means that many Hispanic people are already living with diabetes or prediabetes without knowing it. About 11.3% of Hispanic adults have been diagnosed with diabetes, compared to 10% of the general U.S. population, but that number underestimates the real gap because Hispanic communities also have higher rates of undiagnosed disease.
A Genetic Factor Unique to This Population
One of the most important discoveries in diabetes genetics directly affects people with Indigenous American and Latin American ancestry. A gene variant called SLC16A11, carried by roughly 30% of people with Mexican or Latin American descent, increases the risk of type 2 diabetes by about 25% per copy of the variant. By comparison, fewer than 2% of people with European ancestry carry it, and it’s essentially absent in people of African descent. Researchers estimate this single gene variant explains about 20% of the higher diabetes rates seen in Mexico.
The variant works in two ways. It reduces the amount of a transporter protein produced in the liver, and it prevents that protein from reaching the cell surface where it normally functions. People who inherit two copies of the variant may end up with roughly 85% less of this transporter active in their cells. The protein appears to play a role in how the liver processes fats and sugars, which helps explain why so many people with no obvious lifestyle risk factors still develop the disease. This doesn’t mean diabetes is inevitable, but it does mean that prevention efforts need to start earlier and be more aggressive for people in this population.
Most People With Prediabetes Don’t Know It
Prediabetes is the stage where blood sugar is elevated but not yet high enough for a diabetes diagnosis. It’s reversible with lifestyle changes, which makes catching it early critical. Among Hispanic adults with prediabetes, only about 14% are aware they have the condition. That means roughly 86 out of 100 Hispanic people with prediabetes have no idea they’re on the path toward full diabetes.
The American Diabetes Association recommends that all adults begin screening at age 35. But if you’re younger than 35 and have a BMI of 25 or higher along with at least one other risk factor (being Hispanic counts as a risk factor, along with family history, physical inactivity, or a history of gestational diabetes), screening should start earlier. A simple fasting blood sugar or A1C test is all it takes. If you have a parent or sibling with type 2 diabetes and you haven’t been tested, that’s worth prioritizing regardless of your age.
Kidney Disease Hits This Community Harder
Diabetes is the leading cause of kidney failure in the United States, and Hispanic Americans bear a disproportionate share of that burden. The prevalence of kidney failure linked to diabetes has been roughly twice as high in Hispanic people compared to non-Hispanic populations since at least 2001. In border communities near Mexico, as many as 90% of Mexican American patients with end-stage kidney disease also have type 2 diabetes, compared to about 50% of non-Hispanic white patients with kidney failure.
Some regional data paints an even starker picture. A survey in south-central Texas found that Hispanic residents developed kidney failure at four to nine times the rate of their non-Hispanic white neighbors. Between 1996 and 2006, the rate of new kidney failure cases grew faster among Mexican Americans than among African Americans or Native Americans. The takeaway is that blood sugar control isn’t just about avoiding diabetes complications in the abstract. For Hispanic people with diabetes, protecting kidney function through regular monitoring (a simple urine test can detect early damage) is one of the most important things you can do.
Vision Loss Is More Common Than Expected
Nearly half of Hispanic and Latino adults with diabetes have some degree of diabetic retinopathy, the condition where high blood sugar damages the tiny blood vessels in the back of the eye. Among those with diabetes, about 6% already have meaningful vision impairment, and more than 8% need laser treatment to prevent further vision loss. These numbers come from direct eye exams of study participants, not self-reported data, so they’re likely a reliable picture of what’s happening in the broader community.
Diabetic retinopathy often causes no symptoms in its early stages, which is why annual dilated eye exams matter. By the time you notice blurry vision or dark spots, permanent damage may already have occurred. If you have diabetes and haven’t had an eye exam in the past year, that’s one of the highest-value appointments you can make.
Gestational Diabetes and Long-Term Risk
About 6.2% of Hispanic women develop gestational diabetes during pregnancy, a rate slightly higher than the general population. But the pattern varies in an interesting way depending on how long someone has lived in the United States. Foreign-born Hispanic women who have been in the U.S. for fewer than 10 years have 46% lower odds of gestational diabetes compared to U.S.-born Hispanic women. After 10 or more years of U.S. residence, that protective effect disappears entirely, with rates climbing to 12.2% in that group. This suggests that adopting American dietary patterns and lifestyle habits plays a significant role.
What makes gestational diabetes especially important is the long-term consequence. Women who have had gestational diabetes are nearly 10 times more likely to develop type 2 diabetes later in life. The risk increases over time: about 20% will have type 2 diabetes within 10 years, and up to 60% within 50 years. If you had gestational diabetes with any pregnancy, regular blood sugar screening for the rest of your life is essential, not optional.
Type 2 Diabetes Is Rising in Hispanic Youth
Type 2 diabetes was once considered an adult disease, but that’s no longer the case. Hispanic youth develop type 2 diabetes at more than four times the rate of non-Hispanic white youth (0.079% versus 0.017%), and the overall rate in young people increased by 30% between 2001 and 2009. While the absolute numbers are still small, the trend is moving in the wrong direction, and Hispanic children are at the leading edge of it. For parents, this means paying attention to weight, physical activity, and sugary drink consumption in children, especially if there’s a family history of diabetes.
Traditional Foods Aren’t the Problem
A common misconception is that traditional Latin American diets are inherently bad for blood sugar. Research from the American Diabetes Association actually tested a Mexican-style diet built around low-glycemic foods and found it improved metabolic markers in people with type 2 diabetes over six weeks. The key distinction wasn’t avoiding cultural staples but choosing the right versions of them.
Corn tortillas, for instance, didn’t need to be eliminated. They had a neutral effect on blood sugar compared to the alternatives. Pinto beans, a cornerstone of many traditional diets, were actively beneficial because they release sugar slowly. The foods that caused problems were the ones that have crept into modern eating patterns: white bread, white long-grain rice, and potatoes. Swapping white rice for beans, choosing whole-grain bread over white, and favoring lower-sugar fruits made the difference. The traditional foundation of a Latin American diet, built around beans, corn, and vegetables, is actually well-suited for blood sugar management when it hasn’t been replaced by processed alternatives.
Income and Education Drive the Disparity
The diabetes gap between Hispanic and non-Hispanic Americans isn’t fully explained by genetics or food choices. A major decomposition analysis found that differences in education and income are the largest contributors to the disparity, even larger than differences in BMI or health behaviors. Over a third of the Hispanic population in the U.S. lacks a high school level of education, and nearly double the proportion of Hispanic people live below the federal poverty line compared to non-Hispanic people.
The analysis found that if Hispanic Americans had the same levels of education and income as their non-Hispanic peers, they would actually have lower rates of diabetes than the general population. Education accounted for up to 88% of the explainable gap in some models. This matters because it reframes diabetes in Hispanic communities as partly a problem of access: access to health information, access to affordable healthy food, access to preventive care. Hispanic Americans remain the group most likely to be uninsured in the United States, which means routine screening and early intervention often don’t happen until the disease is already advanced.
