Diabetes and Asian American People

Nationwide, more than 1 in 5 people who have diabetes don’t know they have it. But for Asian American people, that number is higher—around 1 in 3. Why aren’t more getting diagnosed?

Risk for type 2 diabetes increases at a lower BMI.

Looks Can Be Deceiving

Body weight plays a big part. Being overweight is a risk factor for developing type 2 diabetes, but most Asian American people aren’t considered overweight and so may not seem to be at risk (their doctors may not think they are either!).

But people of Asian descent may have less muscle and more fat than other groups and can develop diabetes at a younger age and lower body weight. That extra body fat tends to be in the belly (visceral fat). Unlike fat stored just under the skin (subcutaneous fat), visceral fat is out of sight, wrapped around organs deep in the body. You can’t tell how much visceral fat someone has by just looking at them.

Visceral fat drives certain processes in the body that can increase the risk for heart disease, stroke, and other serious health conditions. Everybody has some visceral fat, but having too much is a major risk factor for developing type 2 diabetes.

How Much is Too Much?

Most health professionals rely on BMI, or body mass index, to assess whether their patients are in the overweight range (BMI of 25 or greater), which suggests they have excess visceral fat. All adults who are overweight should talk to their doctor about getting tested for type 2 diabetes. Like high blood pressure, diabetes often starts without symptoms, so a blood sugar test is needed to know for sure if someone has the condition.

But the standard BMI classification doesn’t catch Asian American people who are in the healthy weight range (18.5 to 24.9) but may have too much visceral fat and already be at risk for type 2 diabetes. Researchers now suggest that people of Asian heritage get tested for high blood sugar if their BMI is 23 or greater. Type 2 diabetes can be prevented or delayed, but only if people know they’re at risk and can take action!
