Bindi Irwin underwent emergency surgery for a ruptured appendix and endometriosis lesions earlier this month, sharing a number of photos from her hospital bed.

But on Sunday, the wildlife queen, 26, looked to be back to her best, sharing a positive update on her health journey.

Irwin was forced to miss the annual Steve Irwin Gala in Las Vegas this month when she was hospitalised with a ruptured appendix. After undergoing surgery, Irwin appears to have taken a flight to New York City, sharing a number of photos in Manhattan.

“Healing,” Irwin began her Instagram post.

“Thank you for your incredible words of kindness. The reason I share my health journey is because more girls and women desperately need answers to their undiagnosed pain.”

Irwin went on to speak about the pain she endures as an endometriosis sufferer.

“I’ve battled endometriosis for more than 12 years.

“This disease is crippling and can make you feel incredibly isolated.

“We need to raise awareness and change the narrative for women’s health.

“I see you, your pain is real, and you deserve answers and genuine healthcare.”

Fans were delighted Irwin was on the mend.

“Thank you for always being so vulnerable, sharing and educating in everything you do,” one person wrote.

“So glad you’re on your way to feeling better and healing. Love you, Bindi! Keeping you in my prayers endo sister,” another wrote.

“I just found out I have it. Had surgery in March. Explains a lot. The chronic pain is crazy. Thank you for sharing.”

Irwin last shared an update from her hospital bed earlier this month.

“I had my appendix removed. I also had 14 new endometriosis lesions that had to be removed and they kindly stitched up my hernia as well,” the mother-of-one said in a video from her hospital bed.

“I’m sorry if I’m a little out of it in this video, but I just wanted you to know that I’m on the road to recovery one step at a time and I am so lucky to have so much love in my life from my beautiful family.”

Irwin has had a well-documented struggle with endometriosis, which causes the cells that line the uterus to grow in other parts of the body, creating painful scar tissue, according to Health Direct.

Irwin’s mother, Terri, rushed to be by her side when she was hospitalised, while her brother Robert gave an update to People magazine after the emergency.

“She’s going to be OK, but surgery — out of all the things we were ready for — that was not one of them,” Robert told the publication.

“She’s just come out the other side of endometriosis and now the appendix goes.

“She’s devastated that she and mum can’t be here, but I know she’ll make a speedy recovery.”
