Definition & Meaning of "colic"

What is "colic"?

Colic is a condition often seen in infants, characterized by prolonged periods of intense crying and fussiness, usually occurring in the late afternoon or evening. It often begins a few weeks after birth and can last until the baby is about three to four months old. The exact cause of colic is unknown, but it is thought to be related to digestive discomfort, gas, a developing nervous system, or an immature digestive system. Despite being distressing for both the baby and parents, colic is generally harmless and resolves on its own.
