Innie

An innie, or inward navel, is a term used to describe a navel that is recessed or indented rather than protruding. It contrasts with an outie, a navel that protrudes from the abdomen.

Anatomy and development: After birth, the umbilical stump dries and falls away, and the surrounding scar tissue and abdominal structures determine whether the navel forms a depression (innie) or a protrusion (outie). Variation in depth and shape is common, with some innies being shallow and others deeper. Body fat distribution and abdominal muscle tone can influence the visible depth of the navel.

Medical perspective: An innie is typically a normal anatomical variation and not a medical condition. An outie can result from circumstances such as an umbilical hernia or granuloma, but many navels that protrude are not dangerous unless accompanied by symptoms. If an innie changes suddenly in depth or is associated with pain, redness, discharge, or swelling, medical evaluation is advisable.

Cultural and cosmetic notes: The terms innie and outie are widely used in popular language to describe navel appearance. Some individuals seek cosmetic procedures, such as umbilicoplasty, to alter the navel’s appearance for aesthetic reasons.
