Type 2 diabetes usually begins with insulin resistance, a condition in which muscle, liver, and fat cells do not use insulin well. As a result, your body needs more insulin to help glucose enter cells. At first, the pancreas makes more insulin to keep up with the added demand. Over time, the pancreas can’t make enough insulin, and blood glucose levels rise.
In addition, getting too little sleep can increase your appetite and reduce your level of satiety, causing you to crave carbohydrates and sugary foods, in particular. Over time, indulging in these cravings or overeating, in general, can wreak havoc on your insulin and blood sugar levels, as well as your body weight. (Remember: Obesity is a major risk factor for type 2 diabetes.) Plus, when you’re short on sleep, you’re more likely to feel tired and less inclined to exercise, which is a problem because regular exercise helps with weight management and blood sugar control.
Type 2 DM is primarily due to lifestyle factors and genetics. A number of lifestyle factors are known to be important to the development of type 2 DM, including obesity (defined by a body mass index of greater than 30), lack of physical activity, poor diet, stress, and urbanization. Excess body fat is associated with 30% of cases in those of Chinese and Japanese descent, 60–80% of cases in those of European and African descent, and 100% of Pima Indians and Pacific Islanders. Even those who are not obese often have a high waist–hip ratio.
On top of tracking your blood glucose and meals (with a nutrition database and bar-code scanner), the Diabetes:M app will calculate insulin boluses for you. Through the Apple Health app, Diabetes:M will sync with other devices, including glucose meters, Fitbit, Garmin, and many others. You’ll need to pay extra for the subscription to access the full food database, sync multiple devices, and get rid of the ads. (The current subscription cost is $4.99 per month or $49.99 per year.)
Gestational diabetes develops in pregnant women who have never had diabetes. If you have gestational diabetes, your baby could be at higher risk for health problems. Gestational diabetes usually goes away after your baby is born but increases your risk for type 2 diabetes later in life. Your baby is more likely to have obesity as a child or teen, and more likely to develop type 2 diabetes later in life too.
Sometimes the simplest technology is the most important. Jeniece Ilkowitz, CDE, a research nurse and diabetes educator at New York University Langone Health in New York City, recommends that all her patients have this app and set it to show a medical alert on the lock screen, information that can be critical to first responders in an emergency. The Medical ID app is part of the Health app that comes standard on iPhones (therefore, there's no rating on Apple), and it’s simple to set up. If you have an Android device, you’ll have to download it from Google Play.
Type 1 diabetes occurs because the insulin-producing cells of the pancreas (beta cells) are damaged. In type 1 diabetes, the pancreas makes little or no insulin, so sugar cannot get into the body's cells for use as energy. People with type 1 diabetes must use insulin injections to control their blood glucose. Type 1 is the most common form of diabetes in people who are under age 30, but it can occur at any age. Ten percent of people with diabetes are diagnosed with type 1.
Diabetes Companion is one of two apps on the list by mySugr, an Austrian company that raised money earlier this year. The company adds a little bit of gamification to the traditional diabetes management app. "The Companion is a charming, sometimes outspoken diabetes manager that focuses on making your diabetes data useful in everyday life," the app store description says. "Adding elements of fun, gamification, and immediate feedback (with attitude!) through a diabetes monster to help keep you motivated and involved in your therapy." The app works with Sanofi-Aventis' iPhone-connected IGBStar meter and is a registered class I medical device.
Lifestyle change has been proven effective in preventing or delaying the onset of type 2 diabetes in high-risk individuals. Based on this, new public health approaches are emerging that may deserve monitoring at the national level. For example, the Diabetes Prevention Program research trial demonstrated that lifestyle intervention had its greatest impact in older adults and was effective in all racial and ethnic groups. Translational studies of this work have also shown that delivery of the lifestyle intervention in group settings at the community level are also effective at reducing type 2 diabetes risk. The National Diabetes Prevention Program has now been established to implement the lifestyle intervention nationwide.
In type 2 diabetes, there also is a steady decline of beta cells that adds to the process of elevated blood sugars. Essentially, if someone is resistant to insulin, the body can, to some degree, increase production of insulin and overcome the level of resistance. After time, if production decreases and insulin cannot be released as vigorously, hyperglycemia develops.
You can manually enter your blood glucose values in the app or buy their special cable to upload your glucometer readings to the app. For every glucose entry, add notes about medications, mood, exercise, and meals (you can even add a photo of your meal for a quick record), and then track your trends over the course of the day and long term. This app also has features for tracking blood pressure, weight, and A1C.
The earliest predictor of the development of type 2 diabetes is low insulin sensitivity in skeletal muscle, but it is important to recognize that this is not a distinct abnormality but rather part of the wide range expressed in the population. Those people in whom diabetes will develop simply have insulin sensitivity, mainly in the lowest population quartile (29). In prediabetic individuals, raised plasma insulin levels compensate and allow normal plasma glucose control. However, because the process of de novo lipogenesis is stimulated by higher insulin levels (38), the scene is set for hepatic fat accumulation. Excess fat deposition in the liver is present before the onset of classical type 2 diabetes (43,74–76), and in established type 2 diabetes, liver fat is supranormal (20). When ultrasound rather than magnetic resonance imaging is used, only more-severe degrees of steatosis are detected, and the prevalence of fatty liver is underestimated, with estimates of 70% of people with type 2 diabetes as having a fatty liver (76). Nonetheless, the prognostic power of merely the presence of a fatty liver is impressive of predicting the onset of type 2 diabetes. A large study of individuals with normal glucose tolerance at baseline showed a very low 8-year incidence of type 2 diabetes if fatty liver had been excluded at baseline, whereas if present, the hazard ratio for diabetes was 5.5 (range 3.6–8.5) (74). In support of this finding, a temporal progression from weight gain to raised liver enzyme levels and onward to hypertriglyceridemia and then glucose intolerance has been demonstrated (77).
Exercise. Exercising helps your body use insulin and lower your blood sugar level. It also helps control your weight, gives you more energy, and is good for your overall health. Exercise also is good for your heart, your cholesterol levels, your blood pressure, and your weight. These are all factors that can affect your risk of heart attack and stroke. Talk with your doctor about starting an exercise program.
The classic oral glucose tolerance test measures blood glucose levels five times over a period of three hours. Some physicians simply get a baseline blood sample followed by a sample two hours after drinking the glucose solution. In a person without diabetes, the glucose levels rise and then fall quickly. In someone with diabetes, glucose levels rise higher than normal and fail to come back down as fast.
The development of type 2 diabetes is caused by a combination of lifestyle and genetic factors. While some of these factors are under personal control, such as diet and obesity, other factors are not, such as increasing age, female gender, and genetics. Obesity is more common in women than men in many parts of Africa. A lack of sleep has been linked to type 2 diabetes. This is believed to act through its effect on metabolism. The nutritional status of a mother during fetal development may also play a role, with one proposed mechanism being that of DNA methylation. The intestinal bacteria Prevotella copri and Bacteroides vulgatus have been connected with type 2 diabetes.

Tyler played college basketball at Utah State from 2007-2011, and had the opportunity to play in three NCAA tournaments. His coaches and trainers always had Gatorade or candy on hand in case his blood glucose dropped during a game. Tyler tested his blood glucose right before training, and during halftime breaks. He says working out and playing basketball has helped him to better control his T1D.
The connection may be hard to imagine. But the primary reason that regularly skimping on shuteye can increase your risk of type 2 diabetes is because your hormone levels get thrown out of whack. Specifically, with ongoing sleep loss, less insulin (a hormone that regulates blood sugar) is released in the body after you eat. Meanwhile, your body secretes more stress hormones (such as cortisol), which helps you stay awake but makes it harder for insulin to do its job effectively. The net effect: Too much glucose stays in the bloodstream, which can increase your risk of developing 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.
