An Ohio woman has confiscated the Xbox of her 15-year-old son who was hospitalized for dehydration after spending at least four days in his bedroom playing the Modern Warfare 3 video game, WCMH TV reports.

Jesse Rawlins tells the NBC affiliate in Columbus that her son, Tyler Rigsby, emerged from his bedroom Tuesday morning after a marathon round of game-playing, and collapsed three times.

She says he became very pale and his lips turned blue.

"I was very scared. I thought he was going to die," she tells WCMH. "He just fell over three times."

The TV station quotes an emergency physician at a children's hospital as saying dehydration can lead to decreased blood pressure and a lack of adequate oxygen to the brain.

Rawlins, who says Tyler had only left his bedroom to use the bathroom, pick up snacks and take a quick shower, adds that both have learned a lesson the hard way.

She says Tyler was shaken by the ordeal, and didn't complain about his punishment.

"The Xbox is gone," she says.
