The 10-episode prequel to "Game of Thrones," called "House of the Dragon," lays out how the House of Targaryen got entangled in a civil war known as the Dance of the Dragons. Fans are debating whether or not it pales in comparison to the original series.

While the verdict on that is not in yet, we know for sure that when kids have a prequel to diabetes — called prediabetes — they can be in for some pretty high drama if they don't get it under control.

Unfortunately, that's a challenge more and more kids are facing.

A 20-year study published in JAMA Pediatrics reveals that the incidence of prediabetes in 12- to 19-year-olds ballooned between 1999 and 2018.

Males were especially affected. Their rate jumped from 15.8% to 36.4% at the study's end. Females' rates went from 7.15% to 19.6%.

Prediabetes was defined as having an A1c of 5.7% to 6.4% or a fasting plasma glucose level of 100 mg/dL to 125 mg/dL. It increases the risks for premature diabetes, heart and kidney disease, arthritis, cancer, mental dysfunction, and more. Ask your pediatrician to administer a glucose test when your child is in for a checkup.

Weight gain and sedentary behavior are prime drivers of prediabetes in children and teens. The solutions are to eliminate fast foods, highly processed foods, and added sugars, and to encourage kids to play, join organized sports, and put down their digital screens.
