In 2019, Wendy revealed to her audience that she had been diagnosed with lymphedema, which causes swelling in the arms or legs from a lymphatic system blockage. It can be brought on by damage to the lymph nodes or the removal of them. But, in Wendy’s case, it was easily treated. She explained on her show that she had been given a machine to use at home to reduce the swelling in her ankles and legs.

"It's not going to kill me, but I do have a machine — and how dare you talk about the swelling of it all," Wendy said at the time. "I’ve got it under control. If [the swelling] in my feet never goes all the way down, at least I have this machine. I sit for 45 minutes a day. It’s the best party entertainer ever. Everybody [that] comes over wants to do it."
