The bizarre physical phenomenon where your body swallows its own tissue

How Pilates Caused a Woman's Body to Swallow One of Her Breasts · 3:49 · Video: Today I Found Out · Watch at the source

In short: While performing a common fitness maneuver, a 59-year-old woman experienced a startling anatomical anomaly. This video explores the specific mechanics of how intense core pressure can cause the body to literally internalize breast tissue.

The incident occurred during a Pilates class while the woman was performing the Valsalva maneuver—a technique involving forceful exhalation against a closed airway or increased intra-abdominal pressure. This sudden spike in pressure led to her body "swallowing" one of her breasts.

The video provides a first-hand account from a Maryland resident to explain the strange set of circumstances and physiological mechanics that allowed for such an unusual physical outcome.
