Type 2 diabetes is the most common form of diabetes. Read on to learn some of the key facts and statistics about the people who have it and how to manage it.
Many risk factors for type 2 diabetes include lifestyle decisions that can be reduced or even cut out entirely with time and effort. Men are also at slightly higher risk of developing diabetes than women. This may be more associated with lifestyle factors, body weight, and where the weight is located (abdominally versus in the hip area) than with innate gender differences.
Significant risk factors include:
- older age
- excess weight, particularly around the waist
- family history
- certain ethnicities
- physical inactivity
- poor diet
Type 2 diabetes is increasingly prevalent but also largely preventable. According to
- Research suggests that 1 out of 3 adults has prediabetes. Of this group, 9 out of 10 don’t know they have it.
- 29.1 million people in the United States have diabetes, but 8.1 million may be undiagnosed and unaware of their condition.
- About 1.4 million new cases of diabetes are diagnosed in United States every year.
- More than one in every 10 adults who are 20 years or older has diabetes. For seniors (65 years and older), that figure rises to more than one in four.
- Cases of diagnosed diabetes cost the United States an estimated
$245 billionin 2012. This cost is expected to rise with the increasing diagnoses.
In pregnancy and parenting
According to the
A child has a 1 in 7 chance of developing diabetes if one parent was diagnosed before age 50. If the parent was diagnosed after age 50, the child has a 1 in 13 chance. The child’s risk may be greater if the mother has diabetes. If both parents have diabetes, the child’s risk is about 50 percent.
In ethnic groups
Certain racial or ethnic groups have higher rates of prediabetes and type 2 diabetes. The risk is higher even after adjusting for other factors. Statistics from
In the United States, type 2 diabetes is more prevalent for certain groups than for white people. These people include:
- Native Americans
- Black people
- Asian Americans
Compared to non-Hispanic white adults in the United States, Asian Americans have a nine percent higher risk of diabetes. Non-Hispanic Black people have a 13.2 percent higher risk. Hispanics have a 12.8 percent higher risk, but this varies depending on national lineage. Currently, the rates of diagnosed diabetes are:
- 8.5 percent for Central and South Americans
- 9.3 percent for Cubans
- 13.9 percent for Mexican Americans
- 14.8 percent for Puerto Ricans
American Indian adults in southern Arizona have the world’s highest rate of type 2 diabetes. One in three are currently diagnosed.
Type 2 diabetes is rare for children of all racial and ethnic backgrounds. Still, it has higher rates in many minority groups than in white people. This is particularly true for Asian Pacific Islanders ages 10 to 19 years. Across all ethnic groups though, type 2 diabetes is increasing around the age of puberty.
The risk of developing type 2 diabetes increases with age.
The number of children diagnosed with type 2 diabetes is growing due to more overweight youth. Still, it is much less common in children and young adults than it is in older people.
For example, consider data from the
Adults ages 40 to 59 comprise the world’s age group with the highest diabetes rates. According to one study, this is expected to shift to adults ages 60 to 79 by 2030.
Type 2 diabetes is on the rise worldwide. The International Diabetes Federation reports that more than 400 million people were living with diabetes as of 2015. The
In 2012, diabetes caused an estimated
Both type 2 diabetes and its side effects can often be prevented or delayed. The most cost-effective methods include getting regular physical activity and maintaining a healthy weight. This means following a healthy diet plan. Regular visits to a healthcare provider are also essential. Medication may be necessary as well. Catching complications early allows for intervention, education, and referral to a specialist when needed.
Keeping a healthy weight is important. The
Get regular checks of your blood cholesterol levels, blood pressure, and blood sugar levels. Work to achieve and maintain healthy levels of each. Having healthy levels of these three indicators greatly reduces your risk of diabetes.
Recall of metformin extended release
In May 2020, the
Food and Drug Administration (FDA)recommended that some makers of metformin extended release remove some of their tablets from the U.S. market. This is because an unacceptable level of a probable carcinogen (cancer-causing agent) was found in some extended-release metformin tablets. If you currently take this drug, call your healthcare provider. They will advise whether you should continue to take your medication or if you need a new prescription.
Problems from type 2 diabetes are common and can be severe. People with diabetes have twice the risk of death of any cause compared to people of the same age without diabetes. In 2014, diabetes was listed as the seventh leading cause of death in the United States. The contribution of diabetes to death may be underreported on death certificates.
Side effects of type 2 diabetes can include:
- heart disease
- blindness and eye problems
- kidney disease
- nervous system complications
- foot problems
- dental disease
- pregnancy complications
- mental health problems, such as depression
- skin issues
WHO estimates that
Diabetes was also the primary cause of kidney failure in 44 percent of all new cases in 2011. During the same year, it was also reported that 228,924 people began treatment for kidney failure due to diabetes.
Sensation problems and amputation
Diabetes causes mild loss of sensation in the extremities in as many as 70 percent of adults who have it. Amputations of lower extremities may eventually be necessary, especially for people with blood vessel disease. More than 60 percent of all nontraumatic amputations of lower limbs occur in people with diabetes. Approximately 73,000 lower-limb amputations were performed in diabetics age 20 and older.
Uncontrolled diabetes during pregnancy can increase the chance of:
- birth defects
- large babies
- other issues that can be dangerous to the baby and the mother
Mental health effects
People with diabetes are twice as likely to suffer from depression as people without diabetes.
