Halsey has said she is dealing with a number of health issues, in a revealing update on Instagram.

Wearing a heart monitor, the singer posted on her Instagram Story saying she’d recently been “hospitalized for anaphylaxis a few times”.

“My health has changed a lot since I got pregnant and gave birth. I started getting really sick, I’ve been kind of sick most of my adult life.”

But the 27-year-old is still “excited and confident” for her next tour.

Halsey has previously spoken about her struggles with endometriosis in the past – which is a condition that affects one in 10 women of any age in the UK – where cells like the ones in the lining of the womb uterus are found elsewhere in the body – including the bowel, ovaries or bladder.

‘Looking for the root cause’
After seeing multiple doctors, the three-time Grammy nominee says she was diagnosed with different conditions.

“I’m still looking for the root cause of some of these things,” Halsey said.

“It could potentially be another type of auto-immune disease, and I’ve known about auto-immune issues for most of my life, especially having endometriosis.”
