Studies have identified at least 150 DNA variations that are associated with the risk of developing type 2 diabetes. Most of these changes are common and are present both in people with diabetes and in those without. Each person has some variations that increase risk and others that reduce risk. It is the combination of these changes that helps determine a person's likelihood of developing the disease.
Foodily is another popular app Apple has included on the list that doesn't have a specific diabetes application. Rather, the app helps users find, keep track of, and share recipes. As a "food social network" that lets people with similar tastes share recipes, though, the app could be helpful in creating a community of people with specific dietary needs and calorie requirements.
In type 1 diabetes, the pancreas loses its ability to make insulin because the body's immune system attacks and destroys the cells that produce insulin. No one knows exactly why this happens, but scientists think it has something to do with genes. But just getting the genes for diabetes isn't usually enough. A person probably would then have to be exposed to something else — like a virus — to get type 1 diabetes.
Diabetes is a number of diseases that involve problems with the hormone insulin. Normally, the pancreas (an organ behind the stomach) releases insulin to help your body store and use the sugar and fat from the food you eat. Diabetes can occur when the pancreas produces very little or no insulin, or when the body does not respond appropriately to insulin. As yet, there is no cure. People with diabetes need to manage their disease to stay healthy.
Findings from the Diabetes Control and Complications Trial (DCCT) and the United Kingdom Prospective Diabetes Study (UKPDS) have clearly shown that aggressive and intensive control of elevated levels of blood sugar in patients with type 1 and type 2 diabetes decreases the complications of nephropathy, neuropathy, retinopathy, and may reduce the occurrence and severity of large blood vessel diseases. Aggressive control with intensive therapy means achieving fasting glucose levels between 70-120 mg/dl; glucose levels of less than 160 mg/dl after meals; and a near normal hemoglobin A1c levels (see below).
In 2017, 425 million people had diabetes worldwide,[8] up from an estimated 382 million people in 2013[17] and from 108 million in 1980.[101] Accounting for the shifting age structure of the global population, the prevalence of diabetes is 8.8% among adults, nearly double the rate of 4.7% in 1980.[8] [101] Type 2 makes up about 90% of the cases.[16][18] Some data indicate rates are roughly equal in women and men,[18] but male excess in diabetes has been found in many populations with higher type 2 incidence, possibly due to sex-related differences in insulin sensitivity, consequences of obesity and regional body fat deposition, and other contributing factors such as high blood pressure, tobacco smoking, and alcohol intake.[102][103]
Diabetes Tracker –  The American Journal of Preventive Medicine ranked this app, which has no free version, No. 1. It boasts an intensive and easy-to-follow educational component in addition to features for monitoring blood glucose, carbs, net carbs and more. Easy to see the big picture with daily and weekly reports. For some, it may be worth the extra expense.
How long will diabetes stay away after weight loss? Long-term normal blood glucose control in previously diabetic individuals after bariatric surgery demonstrates that diabetes does not recur for up to 10 years, unless substantial weight gain occurs (86). These observations are consistent with the twin cycle hypothesis and the existence of a trigger level for adverse metabolic effects of fat in the pancreas. Hence, for a given individual with type 2 diabetes, reducing the liver and pancreas fat content below his or her personal trigger levels would be expected to result in a release from the fatty acid–mediated dysfunction. Individual tolerance of different degrees of fat exposure vary, and understanding this liposusceptibility will underpin the future understanding of genetically determined risk in any given environment. However, this should not obscure the central point: If a person has type 2 diabetes, there is more fat in the liver and pancreas than he or she can cope with.
Carb Manager is the preferred food app for Pamala Moberly, 56, a retired missionary in Tifton, Georgia. “I like that it helps me keep track of total carbs, net carbs, fiber, proteins, and fats. I can even make my own recipes in this app, and it will calculate all of those numbers,” she says. She uses the free version, but adding the subscription service allows you to also enter blood glucose values. (The current subscription price is $8.49 per month or $39.99 per year.)
SparkPeople bills itself as “your personal diet and lifestyle coach,” helping you track small details but also offer a bird's eye view of your wellness. You track your data using its food database, bar-code scanner, and exercise logs. It will sync with many fitness trackers and has built-in videos with exercise demonstrations, as well as a meal-planning function.
The major eye complication of diabetes is called diabetic retinopathy. Diabetic retinopathy occurs in patients who have had diabetes for at least five years. Diseased small blood vessels in the back of the eye cause the leakage of protein and blood in the retina. Disease in these blood vessels also causes the formation of small aneurysms (microaneurysms), and new but brittle blood vessels (neovascularization). Spontaneous bleeding from the new and brittle blood vessels can lead to retinal scarring and retinal detachment, thus impairing vision.
Glucosio is an app for people with type 1 and type 2 diabetes. It monitors important metrics such as weight, hemoglobin A1c, ketones, cholesterol, blood pressure, and more. The app also includes glucose target tools and an HbA1c conversion calculator. Set reminders to keep you in tune with taking medication, working out, and other important tasks. You can share data from the app anonymously if you choose.
