This is the only app in the list designed for doctors, one of a series of Johns Hopkins Guides on different diseases. The diabetes guide, which is a $29.99 in-app purchase "contains the essential diagnosis, classification, and management information needed for diabetic care" and enables physicians to "answer questions with recommendations for complications, drugs, and other treatments," according to the app store description.

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]

“As soon as I noticed the leaking fluids and the hemorrhaging, I suspected that they might be symptoms of diabetes,” recalls Dr. Clary, who practices in the Washington, D.C., suburb of Ashburn, Virginia. “In my 12 years of experience as an eye doctor, that kind of bleeding usually signals that a buildup of sugar in the patient’s bloodstream has begun to break down the capillaries that feed the retina. The result is often what we call diabetic retinopathy – a condition in which continuing damage to retinal tissue from diabetes can lead to impaired vision or even blindness, if left untreated.”
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.
Diabetes is one of the first diseases described[21] with an Egyptian manuscript from c. 1500 BCE mentioning "too great emptying of the urine."[112] The first described cases are believed to be of type 1 diabetes.[112] Indian physicians around the same time identified the disease and classified it as madhumeha or honey urine noting that the urine would attract ants.[112] The term "diabetes" or "to pass through" was first used in 230 BCE by the Greek Apollonius Of Memphis.[112] The disease was rare during the time of the Roman empire with Galen commenting that he had only seen two cases during his career.[112]
“We usually see patients quarterly for appointments, which means the other 361 days of the year, they’re on their own,” says endocrinologist Amber Champion, MD, at Great Plains Health in North Platte, Nebraska. “They need to have the knowledge and tools to take care of themselves. Diabetes-related apps can be useful to help keep track of all the data and see it visually. They can also help educate and teach patients to spot trends and keep their data organized.”
What are symptoms of type 2 diabetes in children? Type 2 diabetes is becoming increasingly common in children, and this is linked to a rise in obesity. However, the condition can be difficult to detect in children because it develops gradually. Symptoms, treatment, and prevention of type 2 diabetes are similar in children and adults.

Change in fasting plasma glucose (A), 2 h post-oral glucose tolerance test (B), and homeostasis model assessment (HOMA-B) insulin secretion (C) during the 16-year follow-up in the Whitehall II study. Of the 6,538 people studied, diabetes developed in 505. Time 0 was taken as the diagnosis of diabetes or as the end of follow-up for those remaining normoglycemic.

Medications used to treat diabetes do so by lowering blood sugar levels. There is broad consensus that when people with diabetes maintain tight glucose control (also called "tight glycemic control") – keeping the glucose levels in their blood within normal ranges – that they experience fewer complications like kidney problems and eye problems.[84][85] There is however debate as to whether this is cost effective for people later in life.[86]

Yes. Once you get a new kidney, you may need a higher dose of insulin. Your appetite will improve so your new kidney will break down insulin better than your injured one. You will use steroids to keep your body from rejecting your new kidney. If your new kidney fails, dialysis treatment can be started while you wait for another kidney.

Though it may be transient, untreated GDM can damage the health of the fetus or mother. Risks to the baby include macrosomia (high birth weight), congenital heart and central nervous system abnormalities, and skeletal muscle malformations. Increased levels of insulin in a fetus's blood may inhibit fetal surfactant production and cause infant respiratory distress syndrome. A high blood bilirubin level may result from red blood cell destruction. In severe cases, perinatal death may occur, most commonly as a result of poor placental perfusion due to vascular impairment. Labor induction may be indicated with decreased placental function. A caesarean section may be performed if there is marked fetal distress or an increased risk of injury associated with macrosomia, such as shoulder dystocia.[50]
The majority of genetic variations associated with type 2 diabetes are thought to act by subtly changing the amount, timing, and location of gene activity (expression). These changes in expression affect genes involved in many aspects of type 2 diabetes, including the development and function of beta cells in the pancreas, the release and processing of insulin, and cells' sensitivity to the effects of insulin. However, for many of the variations that have been associated with type 2 diabetes, the mechanism by which they contribute to disease risk is unknown.
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.
Per the WHO, people with fasting glucose levels from 6.1 to 6.9 mmol/l (110 to 125 mg/dl) are considered to have impaired fasting glucose.[67] people with plasma glucose at or above 7.8 mmol/l (140 mg/dl), but not over 11.1 mmol/l (200 mg/dl), two hours after a 75 gram oral glucose load are considered to have impaired glucose tolerance. Of these two prediabetic states, the latter in particular is a major risk factor for progression to full-blown diabetes mellitus, as well as cardiovascular disease.[68] The American Diabetes Association (ADA) since 2003 uses a slightly different range for impaired fasting glucose of 5.6 to 6.9 mmol/l (100 to 125 mg/dl).[69]
Type 2 diabetes primarily occurs as a result of obesity and lack of exercise.[1] Some people are more genetically at risk than others.[6] Type 2 diabetes makes up about 90% of cases of diabetes, with the other 10% due primarily to diabetes mellitus type 1 and gestational diabetes.[1] In diabetes mellitus type 1 there is a lower total level of insulin to control blood glucose, due to an autoimmune induced loss of insulin-producing beta cells in the pancreas.[12][13] Diagnosis of diabetes is by blood tests such as fasting plasma glucose, oral glucose tolerance test, or glycated hemoglobin (A1C).[3]
Glucose Buddy Diabetes Tracker also allows you to track insulin, carbohydrates, weight, and ketones.  It allows users to save and view a history of their blood sugar records which helps you identify trends in your health.  You can schedule reminders to measure your blood sugar. The app tracks what time of day you are checking your blood sugar.  You can also add a note to each record.  Glucose integrates with HealthKit by writing all inputted entries to the Health app.  Subscriptions are available for premium features such as other apps, graphs, and custom tagging tools.
