Diabetes mellitus occurs throughout the world but is more common (especially type 2) in more developed countries. The greatest increase in rates has however been seen in low- and middle-income countries, where more than 80% of diabetic deaths occur. The fastest prevalence increase is expected to occur in Asia and Africa, where most people with diabetes will probably live in 2030. The increase in rates in developing countries follows the trend of urbanization and lifestyle changes, including increasingly sedentary lifestyles, less physically demanding work and the global nutrition transition, marked by increased intake of foods that are high energy-dense but nutrient-poor (often high in sugar and saturated fats, sometimes referred to as the "Western-style" diet). The global prevalence of diabetes might increase by 55% between 2013 and 2035.
Diabetes has grown to “epidemic” proportions, and the latest statistics revealed by the U.S. Centers for Disease Control and Prevention state that 30.3 million Americans have diabetes, including the 7.2 million people who weren’t even aware of it. Diabetes is affecting people of all ages, including 132,000 children and adolescents younger than 18 years old. (2)
Without insulin, that extra sugar starts to hang out in your blood with nowhere to go. Just like with honey or sweet syrup, high concentrations of sugar causes the blood to thicken. Physiologically, this pulls fluids and water from other parts of the body into the bloodstream, causing swelling and dryness. Early symptoms of diabetes are relatively mild, including excessive peeing, dry mouth, itchy skin, hunger, fatigue, and blurred vision.
Chronic pain creates several vicious cycles. For one, people tend to tense their muscles in response to pain, which often makes the pain worse. Pain also leads people to stop moving, which leads to increasing stiffness and more pain. Pain can interfere with sleep, and restless nights can increase pain. Pain also can contribute to depression and painful emotions such as anger, grief, fear, and frustration, which in turn contribute to pain.
In addition to the problems with an increase in insulin resistance, the release of insulin by the pancreas may also be defective and suboptimal. In fact, there is a known steady decline in beta cell production of insulin in type 2 diabetes that contributes to worsening glucose control. (This is a major factor for many patients with type 2 diabetes who ultimately require insulin therapy.) Finally, the liver in these patients continues to produce glucose through a process called gluconeogenesis despite elevated glucose levels. The control of gluconeogenesis becomes compromised.
Family or personal history. Your risk increases if you have prediabetes — a precursor to type 2 diabetes — or if a close family member, such as a parent or sibling, has type 2 diabetes. You're also at greater risk if you had gestational diabetes during a previous pregnancy, if you delivered a very large baby or if you had an unexplained stillbirth.
