The admission comes weeks after 64-year-old Amy Price was diagnosed with idopathic pulmonary fibrosis, a lung condition with no known cure.
The pair have already appeared on Loose Women to discuss the diagnosis, although Katie has been putting on a brave face when it comes to her public appearances.
Now, speaking during the Stevenage leg of her live show, An Audience with Katie Price, she told fans that she would go to any lengths necessary to prolong her mum's life. Currently, life expectancy for those with the condition is around three to five years.
'We're talking about me giving her one of my lungs,' she told the audience, 'but I'm not sure it will save her.'
The star also revealed that she was training to be a nurse before she went into modelling, and shared surprising plans to go back into healthcare.
'I'm training to be a paramedic – I've started the course and I'm 5 years on from being qualified. I like helping people.'
Speaking on Loose Women earlier this month, brave Amy opened up about how she planned on living every day to the fullest in the time she has left, and insisting she wasn't going anywhere until she saw Katie settled.
'I'm not going to peg off until she's settled,' she told the show's panellists, whom Katie herself joined the ranks of in 2016.
'I think it's about time you got yourself together properly and took life more seriously and be settled,' she told her 39-year-old daughter.
Of her condition, she explained: 'It's like scarring of the lungs and it actually stops you breathing.'
'It's progressive so it goes up your lungs and in the end you won't be able to breathe.'
