Social Democrats TD Jennifer Whitmore is recovering in hospital after being admitted to an intensive care unit earlier this week.
A number of her political colleagues in the Dáil wished her well after it emerged that she had suffered a sudden medical emergency.
In a social post on her Facebook page, her husband said that it had been a “surreal few days”.
Her husband, Tony Duddy, posted: “I just wanted to send out a quick message – it’s been a surreal few days.
“After the excitement of last weekend’s elections, we had a bit of a fright Monday where Jennifer experienced a sudden medical emergency, and I had to call the ambulance.
“She is still in St Vincent’s hospital, and will be there for another few days at least.
“She is doing much better but there will be a recovery period, where she will be easing herself back to work.
“It’s great that we have the summer coming up, but it’s things like this that remind us what is important in life.
“A huge thank you to the incredible staff at St Vincent’s for their speedy intervention, particularly in the ICU.
“The very genuine care that we have experienced over the last few days has really touched us.
“Jennifer’s office continues to operate as normal, but anything requiring Jennifer directly will be slow, apologies in advance for this.”
Speaking in the Dáil on Thursday, Sinn Féin TD Pearse Doherty said: “I want to begin by wishing our colleague Jennifer Whitmore a speedy recovery and look forward to welcoming her back in the benches.
“I read this morning that she was taken to hospital and wish her a speedy recovery.”
The Minister for Finance Michael McGrath said: “Can I join with you in wishing our colleague deputy Jennifer Whitmore best all the best.
“I didn’t realise that she had taken ill but all of our thoughts are with her today.”
Dublin Labour TD Duncan Smith said: “Before I begin I also want to send the best wishes of the Labour Party to deputy Jennifer Whitmore.”
