The prognosis of diabetes is related to the extent to which the condition is kept under control to prevent the development of the complications described in the preceding sections. Some of the more serious complications of diabetes such as kidney failure and cardiovascular disease, can be life-threatening. Acute complications such as diabetic ketoacidosis can also be life-threatening. As mentioned above, aggressive control of blood sugar levels can prevent or delay the onset of complications, and many people with diabetes lead long and full lives.
One of the most common ways people with type 2 diabetes attempt to lower their blood sugar is by drastically reducing their intake of carbs. The ADA agrees that carbohydrate counting is essential if you have diabetes, but extreme diets like the ketogenic diet, which reduces carb intake to as little as 5 percent of your daily calories, can be risky for some people with diabetes.

Pancreatic islet allo-transplantation is a procedure in which islets from the pancreas of a deceased oran donor are purified, processed, and transferred into another person. Immunosuppressive medications are needed to prevent rejection which is a typical challenge with any transplant. These medications carry a number of serious side effects such as decreased kidney function, high blood pressure, anemia and lowered white blood cells counts.
As of 2016, 422 million people have diabetes worldwide, up from an estimated 382 million people in 2013 and from 108 million in 1980. Accounting for the shifting age structure of the global population, the prevalence of diabetes is 8.5% among adults, nearly double the rate of 4.7% in 1980. Type 2 makes up about 90% of the cases. Some data indicate rates are roughly equal in women and men, 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.
Without insulin, that extra sugar starts to hang out in your blood with nowhere to go. Just like with honey or sweet syrup, high concentrations of sugar causes the blood to thicken. Physiologically, this pulls fluids and water from other parts of the body into the bloodstream, causing swelling and dryness. Early symptoms of diabetes are relatively mild, including excessive peeing, dry mouth, itchy skin, hunger, fatigue, and blurred vision.
A major feature of the disease is a condition known as insulin resistance. Insulin is a hormone that moves glucose (sugar), from the bloodstream into the body’s cells where it is used for energy. For a variety of reasons that are not fully understood, the body’s tissues don’t respond adequately to insulin and glucose then becomes elevated in the bloodstream.
The earliest surviving work with a detailed reference to diabetes is that of Aretaeus of Cappadocia (2nd or early 3rd century CE). He described the symptoms and the course of the disease, which he attributed to the moisture and coldness, reflecting the beliefs of the "Pneumatic School". He hypothesized a correlation of diabetes with other diseases, and he discussed differential diagnosis from the snakebite which also provokes excessive thirst. His work remained unknown in the West until 1552, when the first Latin edition was published in Venice.
