Nick Cannon revealed on Instagram that he has been hospitalized with the autoimmune diseases lupus.

“For all who have been trying to contact me the last few days this is where I’ve been,” Cannon wrote. “And I will be in the Hospital through Christmas. All good though, Doctors say I will be back to normal before the New Year. #LupusSucks #ncredible #warrior.”

Cannon was diagnosed with the disease in 2012. He spoke about it during an interview with HuffPost Live earlier this year.

“It was super scary just because you don’t know… you’ve never heard of [lupus],” he said. “I knew nothing about it until I was diagnosed… But to me, I’m healthier now than I’ve ever been before.”

The entertainer told The Huffington Post that he is the only member of his family to have been diagnosed with the disease and explained that a balanced diet and medication helps him stave off potential complications.

“When you hear the words ‘autoimmune disease’ or ‘lupus,’ it’s like, ‘Whoa, what is that?'” he said. “That’s how I felt, and that’s how my family and friends felt as well…. But you realize it’s something that you can live with and actually overcome with the proper research and with the proper support system."
