The most common is type 2 diabetes, usually in adults, which occurs when the body becomes resistant to insulin or doesn’t make enough insulin. In the past 3 decades the prevalence of type 2 diabetes has risen dramatically in countries of all income levels. Type 1 diabetes, once known as juvenile diabetes or insulin-dependent diabetes, is a chronic condition in which the pancreas produces little or no insulin by itself.
For people living with diabetes, access to affordable treatment, including insulin, is critical to their survival. There is a globally agreed target to halt the rise in diabetes and obesity by 2025. About 422 million people worldwide have diabetes, the majority living in low-and middle-income countries, and 1.5 million deaths are directly attributed to diabetes each year.
- Both the number of cases and the prevalence of diabetes have been steadily increasing over the past few decades.
- Symptoms of type 1 diabetes include the need to urinate often, thirst, constant hunger, weight loss, vision changes and fatigue.
- These symptoms may occur suddenly.
- Symptoms for type 2 diabetes are generally similar to those of type 1 diabetes but are often less marked.
As a result, the disease may be diagnosed several years after onset, after complications have already arisen. For this reason, it is important to be aware of risk factors. Type 1 diabetes cannot currently be prevented. Effective approaches are available to prevent type 2 diabetes and to prevent the complications and premature death that can result from all types of diabetes.
These include policies and practices across whole populations and within specific settings (school, home, workplace) that contribute to good health for everyone, regardless of whether they have diabetes, such as exercising regularly, eating healthily, avoiding smoking, and controlling blood pressure and lipids.
The starting point for living well with diabetes is an early diagnosis – the longer a person lives with undiagnosed and untreated diabetes, the worse their health outcomes are likely to be. Easy access to basic diagnostics, such as blood glucose testing, should therefore be available in primary health care settings.
What percentage of the population has diabetes mellitus?
World diabetes prevalence – It is estimated that 415 million people are living with diabetes in the world, which is estimated to be 1 in 11 of the world’s adult population.46% of people with diabetes are undiagnosed. The figure is expected to rise to 642 million people living with diabetes worldwide by 2040.
What is the prevalence of type 2 diabetes?
Other national databases, such as the Center for Disease Control and Prevention Diabetes Surveillance System, reported in 2022 a prevalence of diagnosed diabetes of approximately 11.3 percent of adults (37.3 million people, with 28.7 million with diagnosed diabetes, an estimated 8.5 million undiagnosed, and 95 percent
How common is type 1 or 2 diabetes?
The main difference between the type 1 and type 2 diabetes is that type 1 diabetes is a genetic condition that often shows up early in life, and type 2 is mainly lifestyle-related and develops over time. With type 1 diabetes, your immune system is attacking and destroying the insulin-producing cells in your pancreas.
Although type 1 and type 2 diabetes both have things in common, there are lots of differences. Like what causes them, who they affect, and how you should manage them. For a start, type 1 affects 8% of everyone with diabetes. While type 2 diabetes affects about 90%. Some people get confused between type 1 and type 2 diabetes.
This can mean you have to explain that what works for one type doesn’t work for the other, and that there are different causes. The main thing to remember is that both are as serious as each other. Having high blood glucose (or sugar) levels can lead to serious health complications, no matter whether you have type 1 or type 2 diabetes.
How many diabetics are there in the world in 2022?
How many people have diabetes? – According to the CDC, 463 million adults have diabetes worldwide. In the United States alone, 34.2 million adults have diabetes, 10.5% of the population.
What percentage of adults are diabetic or prediabetic?

What is the leading cause of diabetes worldwide?
Type 2 diabetes – Type 2 diabetes (formerly called non-insulin-dependent, or adult-onset) results from the body’s ineffective use of insulin. More than 95% of people with diabetes have type 2 diabetes. This type of diabetes is largely the result of excess body weight and physical inactivity.
