Little People, Big World star has had a "scary 72 hours" after undergoing emergency brain surgery, his wife has revealed.
The TV personality, 32, had to undergo a shunt revision procedure, with wife Tori Roloff taking to social media to update his fans with a number of photos from his bedside in hospital.
The images showed Zach with a bandage wrapped around his head and a number of wires attached to his chest. A second photo seemed to show Zach in good spirits as he shot a thumbs up in the direction of the camera.
Describing what had gone on to her Instagram followers, Tori wrote: "Not exactly how we saw our week going… Zachary had emergency shunt revision this morning. It's been a scary 72 hours but he is doing well and recovering!!"
She added: "Thank you so much to everyone for the prayers that you have covered us in. We feel them! We are so incredibly blessed by our neurosurgeon team and their attentiveness to Zach's needs!
"Thank you to our friends and family who have all reached out asking to help. We feel so loved and supported by you."
She went on to praise Zach's mum Amy for her help with the couple's three kids, before saying she's hopeful the surgery will help relieve Zach's migraines.
'You're a freaking bad a**, Zach," Tori said. "You just had brain surgery… and handled it like a rockstar. I'm so proud of you."
Amy also addressed the situation on her social media pages. She took to her account to apologise for cancelling a livestream she had planned so she could help the family in their time of need.
"'You have to rise to the occasion and I was happy to be able to for Zach and Tori," she told her followers.
"I'm over here watching the grandkids while... she can be there for Zach. Zach is in the hospital. He has to go through some surgery. We're just hoping and wishing for the best with lots of prayers."
She added that the family would appreciate everyone's prayers for her son. "I'm a firm believer in the power of prayer. And the Good Lord answers them. Regardless, he answers them."
