Though not routinely used any longer, the oral glucose tolerance test (OGTT) is a gold standard for making the diagnosis of type 2 diabetes. It is still commonly used for diagnosing gestational diabetes and in conditions of pre-diabetes, such as polycystic ovary syndrome. With an oral glucose tolerance test, the person fasts overnight (at least eight but not more than 16 hours). Then first, the fasting plasma glucose is tested. After this test, the person receives an oral dose (75 grams) of glucose. There are several methods employed by obstetricians to do this test, but the one described here is standard. Usually, the glucose is in a sweet-tasting liquid that the person drinks. Blood samples are taken at specific intervals to measure the blood glucose.
In the United States, children are becoming obese at triple the rate compared with the 1960s, making the study and treatment of this problem paramount. The epidemic of metabolic syndrome in children and adolescents is an international phenomenon, leading the International Diabetes Foundation to publish an updated consensus statement to guide diagnosis and further study of the condition.

Diabetes experts feel that these blood glucose monitoring devices give patients a significant amount of independence to manage their disease process; and they are a great tool for education as well. It is also important to remember that these devices can be used intermittently with fingerstick measurements. For example, a well-controlled patient with diabetes can rely on fingerstick glucose checks a few times a day and do well. If they become ill, if they decide to embark on a new exercise regimen, if they change their diet and so on, they can use the sensor to supplement their fingerstick regimen, providing more information on how they are responding to new lifestyle changes or stressors. This kind of system takes us one step closer to closing the loop, and to the development of an artificial pancreas that senses insulin requirements based on glucose levels and the body's needs and releases insulin accordingly - the ultimate goal.

Metabolic syndrome is similarly prevalent in men (24%) and women (22%), after adjusting for age.  However, several considerations are unique to women with metabolic syndrome, including pregnancy, use of oral contraceptives, and polycystic ovarian syndrome.  Metabolic syndrome and polycystic ovarian syndrome share the common feature of insulin resistance; they therefore share treatment implications as well.  Cardiometabolic risk is thought to be elevated in both groups.

Globally, an estimated 26% of the world’s population (972 million people) has hypertension, and the prevalence is expected to increase to 29% by 2025, driven largely by increases in economically developing nations.  The high prevalence of hypertension exacts a tremendous public health burden. As a primary contributor to heart disease and stroke, the first and third leading causes of death worldwide, respectively, high blood pressure was the top modifiable risk factor for disability adjusted life-years lost worldwide in 2013.

Not so anymore. Thanks to the rising obesity epidemic in young people, kids and teens are getting these conditions — and they're getting them earlier than ever before. Some estimates say that nearly 1 in 10 teens — and over a third of obese teens — have metabolic syndrome. And a study of 375 second- and third-graders found that 5% had metabolic syndrome and 45% had one or two risk factors for it. https://i.ytimg.com/vi/-wDavU9u0rQ/hqdefault.jpg?sqp
Monitoring your caloric intake may be helpful if you’re overweight, but everyone with type 2 diabetes should track how many carbs they’re taking in. That can be tricky because carbs are in many of the common foods you may already eat, but there are both good and bad sources of carbs. Fruits and vegetables, for example, are good sources, while pretzels and cookies are bad sources. (29)
In the US, 84.1 million adults—more than 1 in 3—have prediabetes, and 90% of them don’t know they have it. Prediabetes is a serious health condition where blood sugar levels are higher than normal, but not high enough yet to be diagnosed as diabetes. Prediabetes increases your risk for type 2 diabetes, heart disease, and stroke. But through the CDC-led National Diabetes Prevention Program, you can learn practical, real-life changes that can cut your risk for developing type 2 diabetes by as much as 58% (71% if you’re 60 or older).
