Nick Cannon is opening up about the series of health problems he's faced over the last couple of months.
The 31-year-old has revealed that the kidney disease he was hospitalized for earlier this year was a result of an autoimmune disease, People magazine reported.
The kidney disease was caused by "autoimmune disease that [doctors] found in my system," Cannon told People, and went on to say that the doctors told him his "autoimmune [disease] is -- like a lupus type of thing, but no one else in my family has it."
While Cannon didn't explain further what his disease was, we know that autoimmune diseases occur when the body's immune system attacks its own healthy cells. There are more than 100 autoimmune diseases, according to the American Autoimmune Related Diseases Association.
Lupus in particular is when the immune system attacks the body's tissues and organs, according to the Mayo Clinic, and is most known for the butterfly-wing-like rash that appears on the face. Symptoms of lupus are different from case to case, but common symptoms include fever, fatigue, joint pain, the facial rash, chest pain, headaches, dry eyes and skin lesions, the Mayo Clinic reported.
Cannon was hospitalized in January with what his wife Mariah Carey described as a "mild kidney failure." Doctors say she probably meant that Cannon had something called acute kidney injury, or acute kidney failure, which is when the kidneys stop functioning properly and allow fluids, waste and electrolytes to store up in the body, according to the Mayo Clinic.
And just last month, the "America's Got Talent" host was hospitalized again for blood clots in his lung and an enlarged heart ventricle, the New York Daily News reported. Cannon told People that the blood clots were linked with his kidney disease.
Shortly after being hospitalized for the blood clots, Cannon stepped down from his "Rollin" radio show on 92.3 NOW.
He said in a statement on the 92.3 NOW website:
Under doctor's orders, I have been asked to put my health first and cut back on some of my professional commitments in order to allow my body to get the rest that it needs to keep up with the demands of my multi-tasking schedule.
