Diabetes mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels that result from defects in insulin secretion, or its action, or both. Diabetes mellitus, commonly referred to as diabetes (as it will be in this article) was first identified as a disease associated with "sweet urine," and excessive muscle loss in the ancient world. Elevated levels of blood glucose (hyperglycemia) lead to spillage of glucose into the urine, hence the term sweet urine.

With diabetes, the small blood vessels in the body are injured. When the blood vessels in the kidneys are injured, your kidneys cannot clean your blood properly. Your body will retain more water and salt than it should, which can result in weight gain and ankle swelling. You may have protein in your urine. Also, waste materials will build up in your blood.
The accepted view has been that the β-cell dysfunction of established diabetes progresses inexorably (79,82,83), whereas insulin resistance can be modified at least to some extent. However, it is now clear that the β-cell defect, not solely hepatic insulin resistance, may be reversible by weight loss at least early in the course of type 2 diabetes (21,84). The low insulin sensitivity of muscle tissue does not change materially either during the onset of diabetes or during subsequent reversal. Overall, the information on the inhibitory effects of excess fat on β-cell function and apoptosis permits a new understanding of the etiology and time course of type 2 diabetes.
A type 2 diabetes diet or a type 2 diabetic diet is important for blood sugar (glucose) control in people with diabetes to prevent complications of diabetes. There are a variety of type 2 diabetes diet eating plans such as the Mediterranean diet, Paleo diet, ADA Diabetes Diet, and vegetarian diets.Learn about low and high glycemic index foods, what foods to eat, and what foods to avoid if you have type 2 diabetes.
Prediabetes is a condition in which blood glucose levels are higher than normal, but a person does not yet have diabetes. Prediabetes and high blood glucose levels are a risk factor for developing diabetes, heart disease, and other health problems. Other warning signs prediabetes may include increased urination, feeling you need to urinate more often, and/or increased thirst.
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.
If the rapid changes in metabolism following bariatric surgery are a consequence of the sudden change in calorie balance, the defects in both insulin secretion and hepatic insulin sensitivity of type 2 diabetes should be correctable by change in diet alone. To test this hypothesis, a group of people with type 2 diabetes were studied before and during a 600 kcal/day diet (21). Within 7 days, liver fat decreased by 30%, becoming similar to that of the control group, and hepatic insulin sensitivity normalized (Fig. 2). The close association between liver fat content and hepatic glucose production had previously been established (20,22,23). Plasma glucose normalized by day 7 of the diet.
Insulin is a hormone that is produced by specialized cells (beta cells) of the pancreas. (The pancreas is a deep-seated organ in the abdomen located behind the stomach.) In addition to helping glucose enter the cells, insulin is also important in tightly regulating the level of glucose in the blood. After a meal, the blood glucose level rises. In response to the increased glucose level, the pancreas normally releases more insulin into the bloodstream to help glucose enter the cells and lower blood glucose levels after a meal. When the blood glucose levels are lowered, the insulin release from the pancreas is turned down. It is important to note that even in the fasting state there is a low steady release of insulin than fluctuates a bit and helps to maintain a steady blood sugar level during fasting. In normal individuals, such a regulatory system helps to keep blood glucose levels in a tightly controlled range. As outlined above, in patients with diabetes, the insulin is either absent, relatively insufficient for the body's needs, or not used properly by the body. All of these factors cause elevated levels of blood glucose (hyperglycemia).
When you hear the word “diabetes,” your first thought is likely about high blood sugar. Blood sugar is an often-underestimated component of your health. When it’s out of whack over a long period of time, it could develop into diabetes. Diabetes affects your body’s ability to produce or use insulin, a hormone that allows your body to turn glucose (sugar) into energy. Here’s what symptoms may occur to your body when diabetes takes effect.
A1C blood test. This test provides information about a person’s average levels of blood glucose over the previous 3 months. The results are reported as a percentage. A normal A1C level is below 5.7 percent. If your A1C is higher than that, it means your blood sugar has been higher than normal. A test result of 6.5 percent or above indicates diabetes. A result between 5.7 and 6.4 indicates prediabetes.

That’s a feature that Kelli Rush, 41, a homemaker in Fallon, Nevada, appreciates. She was diagnosed with type 2 diabetes in late 2017, and she’s since made huge strides in improving her A1C. She likes to see the estimated number in the app, and she says it closely matched the lab value when she had the blood test. “It’s nice to know that I’m making progress,” she says.

Diabetes can also result from other hormonal disturbances, such as excessive growth hormone production (acromegaly) and Cushing's syndrome. In acromegaly, a pituitary gland tumor at the base of the brain causes excessive production of growth hormone, leading to hyperglycemia. In Cushing's syndrome, the adrenal glands produce an excess of cortisol, which promotes blood sugar elevation.
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 mySugr Junior App was developed to make managing diabetes easier for kids. It also enables parents to keep control over the therapy, even when they're not around and their child is at school or out with friends. The app resembles a game in which the children get points for every entry. The goal is to score a particular amount of points every day. This encourages kids to take care of their diabetes regularly.
Dietary factors also influence the risk of developing type 2 diabetes. Consumption of sugar-sweetened drinks in excess is associated with an increased risk.[33][34] The type of fats in the diet are important, with saturated fats and trans fatty acids increasing the risk, and polyunsaturated and monounsaturated fat decreasing the risk.[26] Eating a lot of white rice appears to play a role in increasing risk.[35] A lack of exercise is believed to cause 7% of cases.[36] Persistent organic pollutants may play a role.[37]
Evidence linking hepatic insulin sensitivity to intraorgan triglyceride content has been steadily accumulating. In insulin-treated type 2 diabetes, insulin dose correlates with the extent of fatty liver (35), and in turn, this is associated with insulin sensitivity to suppression of hepatic glucose production (36). Decreasing the fat content of liver is associated with improvement in insulin suppression of glucose production and, thereby, with improvement in fasting plasma glucose (20,23).
With so many technologies in the marketplace, selecting the right app can be overwhelming. Remember that apps are tools designed to create accountability, track data and help users discover patterns and change behaviors. Trying several apps allows you to experiment with features to find the best fit for your lifestyle and needs. Focus on using app technologies that ease the burden of diabetes management instead of complicating it.
The WHO estimates that diabetes mellitus resulted in 1.5 million deaths in 2012, making it the 8th leading cause of death.[12][101] However another 2.2 million deaths worldwide were attributable to high blood glucose and the increased risks of cardiovascular disease and other associated complications (e.g. kidney failure), which often lead to premature death and are often listed as the underlying cause on death certificates rather than diabetes.[101][104] For example, in 2017, the International Diabetes Federation (IDF) estimated that diabetes resulted in 4.0 million deaths worldwide,[8] using modeling to estimate the total number of deaths that could be directly or indirectly attributed to diabetes.[8]

I just wanted to let you know about an app that I use and love. The app is called “Diabetes:M”. It is free and has helped me manage my diabetes. I am a Type 1. It lets you log carbs, insulin, etc. and you can send all of the info from it by e-mail to your provider. It has graphs and charts that help out a lot as well. Hope this helps someone else as much as it has helped me. Thanks.

Coheso also has an app specifically for pregnant women with gestational diabetes. "This Diabetes in Pregnancy App helps you track all of the factors that keep your blood sugar balanced during and after your pregnancy," the app description reads. "The app makes it a snap to log food (nutrition), blood sugar levels, exercise, oral medications and insulin. You can email the logbook as a PDF file or a spreadsheet that you can share with your doctor."

Diabetes was one of the first diseases described,[107] with an Egyptian manuscript from c. 1500 BCE mentioning "too great emptying of the urine."[108] The Ebers papyrus includes a recommendation for a drink to take in such cases.[109] The first described cases are believed to have been type 1 diabetes.[108] Indian physicians around the same time identified the disease and classified it as madhumeha or "honey urine", noting the urine would attract ants.[108][109]
The classic symptoms of untreated diabetes are unintended weight loss, polyuria (increased urination), polydipsia (increased thirst), and polyphagia (increased hunger).[20] Symptoms may develop rapidly (weeks or months) in type 1 DM, while they usually develop much more slowly and may be subtle or absent in type 2 DM. Other symptoms of diabetes mellitus include weight loss and tiredness.[21]

Up to 40 percent of people with type 2 diabetes eventually develop kidney failure — the kidney's inability to filter waste and fluid from the blood, according to the National Kidney Foundation. As blood flows through tiny vessels in the kidneys, waste products are filtered out and leave the body through urine. Too much sugar in the blood can stress these filters, making it hard for the kidneys to work effectively. After a while, the filters can break down and leak protein into the urine. If kidney damage continues, you may need dialysis or a kidney transplant.

Most cases of diabetes involve many genes, with each being a small contributor to an increased probability of becoming a type 2 diabetic.[10] If one identical twin has diabetes, the chance of the other developing diabetes within his lifetime is greater than 90%, while the rate for nonidentical siblings is 25–50%.[13] As of 2011, more than 36 genes had been found that contribute to the risk of type 2 diabetes.[38] All of these genes together still only account for 10% of the total heritable component of the disease.[38] The TCF7L2 allele, for example, increases the risk of developing diabetes by 1.5 times and is the greatest risk of the common genetic variants.[13] Most of the genes linked to diabetes are involved in beta cell functions.[13]

The GoMeals “Today’s Plate” feature helps monitor each day’s calorie intake, as well as the distribution of carbohydrates, fats and proteins. These three nutrient categories are also represented in a pie chart on the touch screen. A restaurant locator feature helps users locate restaurants based on their current location and the type of cuisine they prefer, as well.
You are more likely to develop type 2 diabetes if you are not physically active and are overweight or obese. Extra weight sometimes causes insulin resistance and is common in people with type 2 diabetes. The location of body fat also makes a difference. Extra belly fat is linked to insulin resistance, type 2 diabetes, and heart and blood vessel disease. To see if your weight puts you at risk for type 2 diabetes, check out these Body Mass Index (BMI) charts.
