"I have lupus and deal with kidney issues and high blood pressure, so I deal with a lot of health issues, and for me that’s when I really started noticing more of the body image stuff," she said. "So for me, I really started to notice when people started attacking me for that."

Gomez continued, "And in reality, that's just my truth, I fluctuate... And that got to me big time. I think for me, that really messed me up for a bit."
