Stephen Colbert is dealing with a new illness that’s affecting his ability to stand up. He was diagnosed with a medical condition called benign positional vertigo. According to the Mayo Clinic, it’s a common form of vertigo that presents a sudden sensation of spinning in one’s head if the position of the head is changed in the wrong way. It can cause “mild episodes” of intense dizziness, nausea, and a loss of balance. Colbert is trying to make the most out of this condition saying, “It’s almost entertaining until I forget,” he said. “And then I go to stand up, and then I just fall down. So, I’m coming to you right now from a very weird angle, slightly listing to port.” He says he’s desperate for things to go back to normal.
