USA TODAY -- Regis Philbin has been battling acid reflux-type stomach issues for months.
Today, he needed a glass of water while on air, prompting Kelly Ripa to ask if he was ok.
"I"m not alright," said Philbin. "I've got the indigestion problem. It's more than indigestion. I just decided yesterday to go in for a ... scope." He explained, "So annoying. Sometimes you have a meal and there's blockage and you can't get the food down. I have to drink the barium and they'll put me under the x-ray or MRI."
"I have done that," said Kelly. "I'm still here."
"Can we film this procedure, Reege?" yelled exec Michael Gelman, off-camera.
"Do you have food allergies?" asked Kelly.
"Who are you, Nurse Nancy?" barked Reege.
Philbin, 79, who has had hip replacement and heart surgery, said, "Everything's fine. I'm going to find out. I'm sure it's nothing. I just don't want to go in for another operation. I'm up to here with that. Do you know what I mean?"
At the end of the chat, Kelly said, "And that was the Regis Philbin medical update!"
