The tennis star had to withdraw from the US Open in 2011 after being diagnosed with the disorder, which is a disease that attacks the cells that produce saliva.

“The fatigue is hard to explain unless you have it,” Williams said. “Some mornings I feel really sick, like when you don’t get a lot of sleep or you have a flu or cold. I always have some level of tiredness. And the more I tried to push through it, the tougher it got.”

She still battles with the disease.
