We've come a long way in our understanding of diabetes. Less than a century ago, the most advanced "treatment" for the condition was a starvation diet, marked by repeated fasting and undernourishment, according to the ​Nutrition Journal​. Thank goodness that line of thinking didn't last more than a few years.

The more we know about diabetes, the better we're able to manage the condition. That's where statistics play a role. Looking at the numbers around diabetes helps us better understand who the condition affects and how, which advances our ability to prevent, screen for and treat it, ultimately improving the lives of those with diabetes.

In the U.S., that's 34 million adults, and most of them have type 2 diabetes, according to a 2020 report by the Centers for Disease Control and Prevention (CDC). Read on to learn more type 2 diabetes statistics.

Type 1 vs. Type 2 Diabetes

Both type 1 and type 2 diabetes are characterized by high blood sugar levels. People with type 1 diabetes have trouble producing a hormone called insulin, which helps shuttle glucose out of the bloodstream and into the body's cells to be stored as energy. In people with type 2 diabetes, the cells don't absorb insulin properly, so the body's blood sugar levels stay elevated, according to the American Diabetes Association (ADA).

Worldwide Prevalence of Diabetes

Diabetes is one of the fastest-growing health conditions in the world, according to the International Diabetes Federation (IDF). Here's a look at just how common it is across the globe.

  • Worldwide, about 463 million adults ages 20 to 79 have diabetes (type 1 and type 2), according to the IDF.
  • Those numbers are expected to grow by about 50% by 2045, when approximately 700 million people are estimated to be living with diabetes.
  • The vast majority of people with diabetes — 90% to 95% of cases — have type 2 diabetes, according to the CDC and IDF.
  • An estimated 1.1 million children under the age of 20 have type 1 diabetes, according to the IDF. (The IDF says it's not possible to estimate the number of children with type 2 diabetes.)
  • Slightly more men than women have diabetes (type 1 or type 2), according to the IDF. About 9.6% of men have diabetes, while about 9% of women have diabetes.
  • In 2019, an estimated 4.2 million people died from diabetes and diabetes complications, according to the IDF.

Prediabetes Statistics

Prediabetes is a condition marked by higher-than-average blood sugar levels that aren't quite high enough to be considered diabetes, according to the CDC. People who have been diagnosed with prediabetes have a 50 percent chance of progressing to type 2 diabetes within the next five to 10 years, according to the National Institute for Diabetes and Digestive and Kidney Diseases.

Here are a few key prediabetes stats:

  • In the U.S., an estimated 88 million adults ages 18 and older have prediabetes, according to the CDC.
  • An estimated 1 in 5 American adolescents ages 12 to 18 have prediabetes, according to a December 2019 study in ​JAMA Pediatrics​.

Gestational Diabetes Data

Gestational diabetes — a form of diabetes that develops during pregnancy — affects 2 to 10 percent of pregnancies in the United States, according to the CDC. Gestational diabetes usually develops around week 24 of pregnancy.

About 50 percent of those who have gestational diabetes will later develop type 2 diabetes, according to the CDC.

Diabetes Complications

Unfortunately, there's a long list of diabetes comorbidities that can contribute to a lower quality of life or even death, including conditions like high blood pressure and kidney disease, as well as mental health concerns like depression and anxiety. Below is a look at data on health issues that commonly coexist with diabetes (both type 1 and type 2).

  • People with diabetes are two to three times more likely to have depression than people who don't have diabetes, according to the CDC.
  • Only 25% to 50% of people with diabetes who have depression will get diagnosed and treated for it, according to the CDC.
  • People with diabetes are 20% more likely than people without diabetes to have anxiety, according to the CDC.
