After some commenters suggested Sel was trying to hide her body, she responded by detailing her struggle with an intestinal bacterial overgrowth.

Selena Gomez has hit out at trolls on TikTok and in the process revealed that she has been diagnosed with the intestinal condition SIBO. The actor and singer is currently promoting her new Netflix movie, Emilia Perez, which was called “one of the most divisive films” after it premiered at the Cannes Film Festival, earlier this year.

Many people living with SIBO experience difficulty with getting a diagnosis. That's because the symptoms of SIBO closely resemble signs of other GI conditions like IBS or indigestion, according to the Cleveland Clinic. However, experts believe that IBS tends to be more pain-predominant, while SIBO is more bloating-predominant, per Yale Medicine.
