Mr Lee took to Twitter on Thursday night, Australian time, to say he was doing OK, despite still remaining in intensive care.
"I am alive. Something went amiss on the summit push after [camp] two," he tweeted.
"In hospital, surprisingly mum is here, which is good to get medical advice.
"Body wrecked with liver problems, no phone and vision damage. Piecing together what happened."
The IT specialist has described himself as "just an average person chasing a long-term dream" - to climb the 14 highest peaks in the world without oxygen or drugs.
His attempt on the world's highest, Mount Everest, failed last week when he was rescued unconscious at 7500 metres.
A Department of Foreign Affairs and Trade spokesperson said on Thursday it was continuing to provide "consular assistance to an Australian man hospitalised in Kathmandu. For privacy reasons we are unable to provide further details".
Lee, formerly from Launceston in Tasmania, wrote on his blog that he wanted to conquer the world's 14 peaks over 8000 metres without oxygen or drugs, a goal he had held "since leaving university".
"Rather than sitting around dreaming about it, I have started trying to achieve this mountaineering challenge," Lee wrote on his blog.
"Maybe I will succeed, maybe not, but it'll be fun, and painful, to try to pursue this."
