Tarek El Moussahas been diagnosed with celiac disease, and his fiancée Heather Rae Young has been there to support him from the start.

“It turns out you have celiac,” Internal Medicine Specialist Dr. Ellen Song tells El Moussa, 40, as he holds hands with Young, 34.

El Moussa slowly nods his head at the news as theSelling Sunsetstar, 34, turns to him and quips, “You don’t even know what that is!”

“No idea what that is,” he admits with a smile, as the doctor says, “You have a gluten allergy,” and explains how the disease works.

Dr. Song adds, “If you stay gluten-free, one, you’ll feel better and two, the risk of cancer is much, much lower.”

El Moussa is already a two-time cancer survivor, havingendured battles with both testicular cancerand thyroid cancer.

“So, my favorite foods or living better and healthier and longer?” El Moussa asks. He then looks to Young, who has been vocal about her vegan diet, and asks, “Gluten is in everything. What am I gonna eat?”

In a separate on-camera interview, theFlip or Flopstar says, “I wasn’t really expecting that news and it’s just gonna be a really big change for me. But the good news is I know what’s wrong and hopefully things will get better.”

“Heather has made a lot of changes in my life. She feeds me, cooks for me, she tells me what to eat, she makes sure I’m taking my vitamins. She’s all over it,” he said at the time.

El Moussa also noted that in 2020 he felt “healthier than I’ve ever been in my life.”
