As of 2015, an estimated 415 million people had diabetes worldwide, with type 2 DM making up about 90% of the cases. This represents 8.3% of the adult population, with equal rates in both women and men. As of 2014, trends suggested the rate would continue to rise. Diabetes at least doubles a person's risk of early death. From 2012 to 2015, approximately 1.5 to 5.0 million deaths each year resulted from diabetes. The global economic cost of diabetes in 2014 was estimated to be US$612 billion. In the United States, diabetes cost $245 billion in 2012.
Though not routinely used any longer, the oral glucose tolerance test (OGTT) is a gold standard for making the diagnosis of type 2 diabetes. It is still commonly used for diagnosing gestational diabetes and in conditions of pre-diabetes, such as polycystic ovary syndrome. With an oral glucose tolerance test, the person fasts overnight (at least eight but not more than 16 hours). Then first, the fasting plasma glucose is tested. After this test, the person receives an oral dose (75 grams) of glucose. There are several methods employed by obstetricians to do this test, but the one described here is standard. Usually, the glucose is in a sweet-tasting liquid that the person drinks. Blood samples are taken at specific intervals to measure the blood glucose.
Though the Oxford English Dictionary traces wellness (meaning the opposite of illness) to the 1650s, the story of the wellness movement really begins in the 1950s. New approaches to healthful living were emerging then, inspired in part by the preamble to the World Health Organization’s 1948 constitution: “Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” Halbert L. Dunn, chief of the National Office of Vital Statistics, was looking for new terminology to convey the positive aspects of health that people could achieve, beyond simply avoiding sickness. In a series of papers and lectures in the late ’50s, Dunn sketched out his concept of “high-level wellness,” defined as “an integrated method of functioning, which is oriented toward maximizing the potential of which the individual is capable.”
The primary complications of diabetes due to damage in small blood vessels include damage to the eyes, kidneys, and nerves. Damage to the eyes, known as diabetic retinopathy, is caused by damage to the blood vessels in the retina of the eye, and can result in gradual vision loss and eventual blindness. Diabetes also increases the risk of having glaucoma, cataracts, and other eye problems. It is recommended that diabetics visit an eye doctor once a year. Damage to the kidneys, known as diabetic nephropathy, can lead to tissue scarring, urine protein loss, and eventually chronic kidney disease, sometimes requiring dialysis or kidney transplantation. Damage to the nerves of the body, known as diabetic neuropathy, is the most common complication of diabetes. The symptoms can include numbness, tingling, pain, and altered pain sensation, which can lead to damage to the skin. Diabetes-related foot problems (such as diabetic foot ulcers) may occur, and can be difficult to treat, occasionally requiring amputation. Additionally, proximal diabetic neuropathy causes painful muscle atrophy and weakness.
Diabetes doesn’t cause nearly as much of a stir in the media compared to HIV or cancer, but a few well-known names are associated with the disease – Halle Berry, Tom Hanks, and Paula Deen. And who doesn’t love that Food Network maven and American celebrity chef? Scandals aside, diabetes comes in two versions – Type I or Type II. In Type I, the pancreas decides to drop out of the physiological rat race and go on to discover its own metabolic purpose in life. As a result, the body generates little or no insulin, a hormone important in sugar metabolism. In Type II, unfortunate dietary choices, such as eating tons of sugar and carbohydrates, jam up the sugar absorption process, causing the body to become resistant to the insulin hormone. Type 2 makes up 90 percent of all cases of diabetes, which is going to be our focus here as we talk about when there will be a cure for diabetes. (Spoiler alert: Probably only after we ban the Big Gulp and the Big Mac.)
In the picture to the right you can see the lunch that I was unbelievably served at the 11th International Congress on Obesity in Stockholm 2010. This is a major international conference for obesity doctors and scientists. The food contains almost exclusively energy from sugar and starches, things that are broken down to simple sugars in the stomach.
The combination of diabetes and excess body weight puts individuals at high risk of complications. For people who are overweight or obese, a five percent reduction in body weight has been shown to improve glycemic control, lipids and blood pressure and to reduce the need for medication. Weight loss always sound easy: Just eat less and exercise more. If only it were that simple! There are numerous reasons why people struggle to lose weight including mindset, practical problems (like a busy lifestyle or limited access to healthy food) and stress eating. Many benefit from joining a support group, advice from a dietician or using online tracking applications such as the Body
In animals, diabetes is most commonly encountered in dogs and cats. Middle-aged animals are most commonly affected. Female dogs are twice as likely to be affected as males, while according to some sources, male cats are also more prone than females. In both species, all breeds may be affected, but some small dog breeds are particularly likely to develop diabetes, such as Miniature Poodles.
