Cause of Amy Schumer's shock diagnosis she received after internet 'came for her' over 'moon face'

Amy Schumer received a shock diagnosis after being trolled for her appearance, and her condition was caused by something you may not have heard of.

The Trainwreck actress was recently hounded with comments about her 'puffier face', leading to her to seek professional advice.

While at the time she admitted that she was dismissive of the comments, and chalked it down to petty online hate, she soon took notice that she was in fact ‘puffier than normal right now’.

Schumer admitted that at first, she shared that 'a woman doesn't need any excuse for her physical appearance and owes no explanation' for her changing face.

Speaking on the Call Her Daddy podcast: “I was like, ‘OK, everybody, like, relax’.”

Then physicians began to comment on her face.

Schumer said: “Doctors were chiming in in the comments and they were, like, ‘No, no … something's really up. Your face looks so crazy.’“

The actress said doctors thought she might have Cushing syndrome, which gives the appearance of a ‘moon face’.

“At first, I was like, ‘F**k off,’" Schumer said, until she realized, ‘wait, I have been getting steroid injections for my scars’ from her breast reduction and Cesarean section.

She added: “So I got these was getting these steroid injections and so it gave me this thing called Cushing syndrome — which I wouldn't have known if the internet hadn't come for me so hard.”

What is Cushing Syndrome?

As per Mayo Clinic, Cushing Syndrome 'happens when the body has too much of the hormone cortisol for a long time'.

The website adds: "This can result from the body making too much cortisol, or from taking medicines called glucocorticoids, which affect the body the same way as cortisol."

Symptoms of the illness includes slow wound healing; acne; weight gain in the face; weight gain around the trunk of the body; and skin that bruises easily.

The illness affects around 13 per million people annually, as per the National Organization of Rare Diseases (NORD).

The star may have developed it due to her steroid injections.

Schumer went on to share: "So I got these was getting these steroid injections and so it gave me this thing called Cushing syndrome — which I wouldn't have known if the internet hadn't come for me so hard."

Thankfully, she went on to admit that she 'got rid' of the condition, and that 'it just has to work itself out'.

The comic told Cooper that before she filmed Kinda Pregnant, which comes out next month: “I learned I had this condition, and that I had something called moon face, and I'm starring in a movie — and there's a camera right in my face.”

“Everyone's like, ‘You look great,'” she said.

But then one friend said to her: “Your face is looking, like, a little bit insane.”

Because of her syndrome, and starring in a film, she was feeling ‘down’ and explained: “I was feeling really down on myself before I started filming this movie … I was, like, really having trouble figuring out how I was going to star in a movie while I had this going on.”

Mayo Clinic says that people can treat the health issue by reducing glucocorticoid use; having a tumor removed if that's the cause; having radiation therapy; or by taking medications that control cortisol production.
