In a word, diabetes is a condition in which the body improperly produces or utilizes insulin. However, what is insulin? It is a hormone, insulin. To assist convert the food you eat into the energy and energy reserves that your body needs to function effectively, your body needs insulin. Your entire body is out of balance when your insulin levels are abnormal.

Sounds easy enough, doesn’t it? Of course, not every diabetic experience the same challenges when using insulin. Some people don’t produce any insulin at all, while others produce too little or don’t use it well.

For this reason, there are various varieties of diabetes, with type 1 and type 2 being the most prevalent. Gestational diabetes, which affects certain women, is another condition that can develop while they are pregnant.

Other forms of diabetes can be brought on by genetic flaws, illnesses like cystic fibrosis, organ transplants, or anti-AIDS medications. Others don’t cleanly fall into either the type 1 or type 2 diabetes categories. Actually, there are over ten distinct types of diabetes!

Despite the fact that you might think you’re the only one with diabetes, you’re most definitely not. Diabetes affects hundreds of millions of people worldwide including millions of Americans. Eight out of every 100 Americans who are 20 years of age or older have diabetes. According to recent data from the Centers for Disease Control and Prevention, that equals close to 26 million people and children with diabetes.

You probably know someone else who has diabetes, so. Someone at your school, in your yoga class, or in your apartment complex could be the culprit. Diabetes can affect everyone, regardless of color or ethnicity, whether they are in good physical condition or not.

But not all diabetics flash a huge neon sign proclaiming, “I have diabetes too!

Each diabetic individual has unique symptoms and therapies. The diabetics you know probably take a subtle and individual approach to controlling their condition.


Famous People with Diabetes

However, some people—celebrities—are very candid about having diabetes. Numerous notable persons with diabetes manage their serious illness while balancing the demands of entertainment, athletics, or politics.

  • Actor Halle Berry
  • Nicole Johnson, 1999’s Miss America
  • The NFL quarterback Jay Cutler
  • Singer Aretha Franklin
  • Larry King, host of a talk program
  • Mike Huckabee, a former Arkansas governor

Although it sounds cliche, this list demonstrates just how much you can do while living with diabetes. It’s comforting to know that having diabetes won’t prevent you from competing in the Olympics, like Gary Hall, or from performing as the lead singer of a ’80s glam rock band, like Bret Michaels.


Diabetes Undiagnosed

In the US, there are around 26 million people who have diabetes. However, only 18.8 million people with diabetes have been diagnosed. This indicates that about a quarter of those who have diabetes are completely unaware of their condition. How could so many of these patients go undiagnosed? Diabetes occasionally begins without any evident signs, unlike many other diseases.

Diabetes affects more than 7 million people who are unaware of it. Since few people are aware that anything is wrong, they are going about with possible minor symptoms of diabetes but haven’t seen a doctor for the necessary testing and diagnosis.

Type 2 diabetes affects the majority of undiagnosed persons. Contrarily, type 1 diabetes rarely goes unnoticed for an extended period of time. The symptoms of type 1 diabetes are so severe, as you’ll discover in later chapters, that the patient seeks medical attention.

Growing Diabetes Rate

You may have heard that diabetes is becoming a more common disease. This is regrettably unquestionably true. According to recent data from the Centers for Disease Control and Prevention, the number of Americans who have diabetes climbed by 3 million over a two-year period.

However, type 1 and type 2 diabetes in youngsters is on the rise. Additionally, diabetes rates are rising among several ethnic groups. The prevalence of diabetes is highest among Native Americans (16.1%), followed by African Americans (12.6%) and Hispanics (11.8%). In contrast, 7.1% of white Americans and 8.4% of Asian Americans in the US have diabetes.

Elderly people are more likely to have diabetes

Diabetes continues to have a greater impact on older persons. For instance, diabetes affects 26.9% of adults 65 and older compared to 11.3% of adults 20 and older.

A World Pandemic

Diabetes rates are rising outside of our boundaries. By 2030, more than 430 million people will have diabetes, according to estimates made in 2010 by the International Diabetes Federation. The World Health Organization predicts that between 2005 and 2030, the number of deaths from diabetes would more than double (WHO). The prevalence of diabetes is among the highest in the United States, as you might assume. However, it isn’t yet first on the list.

Five nations in 2000 with the highest rates of diabetes

  • India
  • China
  • The United States
  • Indonesia
  • Japan

To increase knowledge and aid in the prevention and control of diabetes worldwide, the WHO and other organizations like the International Diabetes Federation are working. For instance, the Life for a Child Program of the International Diabetes Federation aids in providing insulin and other supplies to diabetic children all around the world. Additionally, funding is provided by the Federation to support research into diabetes treatment and prevention.

Diabetes is a disease that is as common as it is old. One of the earliest known diseases in the world is diabetes. In fact, before people fully realized what the illness was, they began to describe it in writing. Some of the oldest known medical publications in the world contain references to diabetes.

Early Diabetes References

  • An ailment known as “passing too much urine” is described in an ancient Egyptian medical treatise from circa 1550 BCE.
  • Aretaeus, a Greek physician who lived in the second century CE, noticed that his patients’ bodies seemed to “melt down” into urine. Aretaeus gave diabetes its name from a Greek term that means “siphon” or “pass through.”
  • Early on, people noticed that diabetics’ urine was exceptionally sweet. In fact, pouring urine close to an anthill was one approach to detect diabetes. If the pee attracted the ants, it contained sugar and was therefore attractive to them.
  • By the 18th century, doctors gave diabetes the Latin name mellitus (honey-sweet), which reflects its sweet flavor.
