The process involves wearing a corset-like device to make the waist smaller without exercise or surgery. The corset is worn for four hours a day to start and then it's made tighter in increments. Experts say it can actually move the lower ribs, making the waist smaller by several inches.
But one expert says it could lead to problems like weakened muscles, constipation and more.
"Your joint movement is not going to be nearly as normal as it should be," Andrew Pitkim, DPT, said. "The lungs can't inflate as well as they should because the ribs are going to be constrained. If there are any women out there with any heart conditions, that would be a red flag."
The medical corsets cost about $150 and should be worn under medical supervision.
