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.
For her part, St Clair thought she was inquiring about a technical glitch. Her brother—the brother who along with three other siblings had gifted her the DNA test for her birthday—wasn’t showing up right in her family tree. It was not a glitch, the woman on the line had to explain gently, if this news can ever land gently: The man St Clair thought of as her brother only shared enough DNA with her to be a half-sibling. In fact, she didn’t match any family members on her father’s side. Her biological father must be someone else.
“The field has suffered from a checkered history 20, 30 years ago, when there were operations that were dangerous. But modern metabolic surgery is very safe,” Cummings said. “The risk of dying from a laparoscopic gastric bypass is a little bit less than the risk of dying from having your gallbladder or appendix removed. But we never consider those risky surgeries; they’re totally bread-and-butter procedures.”
You are more likely to develop type 2 diabetes if you are age 45 or older, have a family history of diabetes, or are overweight. Physical inactivity, race, and certain health problems such as high blood pressure also affect your chance of developing type 2 diabetes. You are also more likely to develop type 2 diabetes if you have prediabetes or had gestational diabetes when you were pregnant. Learn more about risk factors for type 2 diabetes.
Type 2 diabetes: Type 2 diabetes affects the way the body uses insulin. While the body still makes insulin, unlike in type I, the cells in the body do not respond to it as effectively as they once did. This is the most common type of diabetes, according to the National Institute of Diabetes and Digestive and Kidney Diseases, and it has strong links with obesity.
