Entertainment reporter Peter Ford told The Morning Show that Oldfield was diagnosed with pulmonary edema as a result of medication she was taking. It is unclear what medication the mother-of-two was taking or what it is being used for.
"She is in hospital and you can see the oxygen mask attached," he said. "There were seven litres of water retention, a lot on her lungs."
He added: "She is in good hands. She is on the mend. As we know, she is a special friend of The Morning Show."
Lisa, the wife of former One Nation leader David Oldfield, appeared fragile and withdrawn while laying in a hospital bed, in a photo shared on Sunrise, reports The Daily Mail Australia.
Oldfield gave an update on her health via Instagram. The controversial reality star shared a picture of some nice flowers with the following caption: "#fluid starting to drain from my #lungs and feeling much better ! Then just felt like a #princess when my dear darling @johnmcaldwell_ sent me these divine #heritage #roses ! Thank you JC you are one of #naturesgentlemen @kiis1065."
