Some people wear their heart on their sleeve, but one woman has discovered that hers is sitting on the wrong side of her chest.
Claire Mack, 19, from Chicago, recently went to the doctors with a "persistent cough" only to be told that her organs were "flipped" inside her body — a condition called dextrocardia.
The teen, who now lives in New York, shared her story in a series of TikTok videos that have been viewed over three million times and have thousands of comments.
"Me getting a chest x-ray for a cough that wouldn't go away," she wrote in a clip of her walking down the street.
She then changes the frame to reveal her shocking diagnosis.
"The doctors: 'Did you know your heart is on the wrong side of your chest?'"
The acting and humanitarian studies student later posted another video showing her x-ray, comparing it to what a normal person's insides look like.
"All of my organs are flipped!" she exclaimed, pointing out where they should be sitting in her body.
The videos have left many viewers asking why her condition wasn't picked up earlier.
What is dextrocardia?
According to Healthline, Dextrocardia is a rare heart condition in which your heart points toward the right side of your chest instead of the left side.
The condition is congenital, which means people are born with it. Less than 1 per cent of the general population is born with dextrocardia and it is not usually life threatening.
There are two types of dextrocardia.
Dextrocardia situs inversus, which means the heart is pointing towards the right side of the body and Dextrocardia with situs inversus totalis.
With dextrocardia with situs inversus totalis, the other organs such as the abdominal and chest organs, as well as the liver, stomach, and spleen sit in a mirror-image reversal of where they should be.
Dextrocardia affects an estimated 1 out of every 12,000 people worldwide, according to Medical News Today.
