- We're gonna turn now to the GMA cover story and Bindi Irwin pulling back the curtain on her battle with endometriosis and sharing her message for women everywhere. Erielle Reshef is here with the story. Good morning, Erielle. - Good morning, Michael. So many women suffer from endometriosis in silence, and Bindi was no different. She says for years she lived with excruciating pain until finally, she underwent a major surgery and got the diagnosis and life-changing relief. This morning, conservationist Bindi Irwin is speaking out about her debilitating battle with endometriosis. - The pain, fatigue, nausea that I was feeling, it was tackling my whole life. ERIELLE RESHEF: The 24-year-old daughter of the late environmentalist and crocodile hunter, Steve Irwin, appearing by video with her mom and brother at the Endometriosis Foundation of America's Blossom Ball earlier this week. - Just two weeks ago underwent enormous surgery. They found 37 lesions. And now, for the first time in over 10 years, I feel like I have a second chance at life. ERIELLE RESHEF: Her surgeon telling us endometriosis is often overlooked, which can sometimes lead to a 10-year delay in proper diagnosis. - It doesn't show up in any imaging, and there is no blood test. Only by laparoscopy we can really tell, by looking inside directly with a camera, we can diagnose endometriosis. ERIELLE RESHEF: Bindi first revealing her decade-long search for answers in an Instagram post earlier this month, writing, "Validation for years of pain is indescribable." The mom to nearly two-year-old daughter Grace adding, "Please be gentle and pause before asking me or any woman when we'll be having more children. After all that my body has gone through, I feel tremendously grateful that we have our gorgeous daughter." Research shows 11% of women ages 15 to 44 suffer from endometriosis in the US, a condition where cells normally found in the lining of the uterus are found outside the uterus, which can cause severe cramps, pelvic pain, painful intimacy, scar tissue, and infertility. - When it comes to women's symptoms and painful periods, they don't associate with the disease. So the woman has to really pursue and find the doctor that they will be taken seriously. - Now I have this amazing opportunity to focus my energy and life on our conservation work around the world. Our family, my daughter, I feel so incredibly excited for this second chance at life, pain-free. - It is good to see her on the road to recovery. And Bindi says she wants to break the stigma about this disease, encouraging women to be their own health advocates, as you heard there, if they are in pain and not to ignore the signs. We have more about endometriosis and Bindi's story on GoodMorningAmerica.com. So important that she's speaking out. - Absolutely. Hopefully she can help a lot of people, Erielle. Thank you so much. We appreciate it.
