Gestational diabetes can be a scary diagnosis, but like other forms of diabetes, it’s one that you can manage. It doesn’t mean that you had diabetes before you conceived or that you will have diabetes after you give birth. It means that, by working with your doctor, you can have a healthy pregnancy and a healthy baby. No matter what, know that you have all the support you need for both you and your baby to be at your best.
In the 10-year follow-up to the UKPDS, patients in the previously intensively treated group demonstrated a continued reduction in microvascular and all-cause mortality, as well as in cardiovascular events, despite early loss of differences in glycated hemoglobin levels between the intensive-therapy and conventional-therapy groups.  The total follow-up was 20 years, half while in the study and half after the study ended.
According to the National Institutes of Health, the reported rate of gestational diabetes is between 2% to 10% of pregnancies. Gestational diabetes usually resolves itself after pregnancy. Having gestational diabetes does, however, put mothers at risk for developing type 2 diabetes later in life. Up to 10% of women with gestational diabetes develop type 2 diabetes. It can occur anywhere from a few weeks after delivery to months or years later.
The top 10 countries in number of people with diabetes are currently India, China, the United States, Indonesia, Japan, Pakistan, Russia, Brazil, Italy, and Bangladesh. The greatest percentage increase in rates of diabetes will occur in Africa over the next 20 years. Unfortunately, at least 80% of people in Africa with diabetes are undiagnosed, and many in their 30s to 60s will die from diabetes there.
Most cases of diabetes involve many genes, with each being a small contributor to an increased probability of becoming a type 2 diabetic. 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%. As of 2011, more than 36 genes had been found that contribute to the risk of type 2 diabetes. All of these genes together still only account for 10% of the total heritable component of the disease. 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. Most of the genes linked to diabetes are involved in beta cell functions.

Prediabetes, as defined by the American Diabetes Association, is that state in which blood glucose levels are higher than normal but not high enough to be diagnosed as diabetes. It is presumed that most persons with prediabetes will subsequently progress to diabetes. In 2015, according to the CDC report, prediabetes was present in 23.1 million persons aged 65 years or older (48.3%). 
Some people with diabetes use a computerized pump -- called an insulin pump -- that gives insulin on a set basis. You and your doctor program the pump to deliver a certain amount of insulin throughout the day (the basal dose). Plus, you program the pump to deliver a certain amount of insulin based on your blood sugar level before you eat (bolus dose).
Maturity onset diabetes of the young (MODY) is a rare autosomal dominant inherited form of diabetes, due to one of several single-gene mutations causing defects in insulin production. It is significantly less common than the three main types, constituting 1-2% of all cases. The name of this disease refers to early hypotheses as to its nature. Being due to a defective gene, this disease varies in age at presentation and in severity according to the specific gene defect; thus there are at least 13 subtypes of MODY. People with MODY often can control it without using insulin.
Gestational diabetes mellitus (GDM) resembles type 2 diabetes in several respects, involving a combination of relatively inadequate insulin secretion and responsiveness. It occurs in about 2–10% of all pregnancies and may improve or disappear after delivery. However, after pregnancy approximately 5–10% of women with GDM are found to have DM, most commonly type 2. GDM is fully treatable, but requires careful medical supervision throughout the pregnancy. Management may include dietary changes, blood glucose monitoring, and in some cases, insulin may be required
