The pop superstar has just completed her Revival World Tour when she revealed her health condition.
"As many of you know, around a year ago, I revealed that I have lupus, an illness that can affect people in different ways. I've discovered that anxiety, panic attacks and depression can be side effects of lupus, which can present their own challenges," she said as quoted by People Magazine.
She vowed to focus on maintaining her health and happiness while thanking her fans for their support.
"You know how special you are to me, but I need to face this head on to ensure I am doing everything possible to be my best. I know I am not alone by sharing this, I hope others will be encouraged to address their own issues," she added.
Prior to this announcement, Gomez involved in a feud between her former boyfriend Justin Bieber and his fans, which prompted him to deactivate his Instagram account. She rebuked Bieber and urged him to refrain from threatening his fans who dislike his current girlfriend Sophia Richie.
Selena's friends were worried that her resurrected clash with Bieber may have taken toll on her health.
