Symptoms:

Colic most often begins at the same time every day. Usually, babies with colic are most fussy in the evening.

Colic symptoms often begins suddenly. The babies hands may be in a fist, the legs may curl up, and the belly may seem swollen. The episode may last for minutes or hours. It often winds down when the baby is exhausted, or when gas or stool is passed.

Despite apparent belly pain, infants with colic eat well and gain weight normally.

Signs and tests:

Your health care provider can often diagnose colic by asking questions about the baby's medical history and symptoms, including how long the crying lasts.

The health care provider will perform a physical exam to rule out other problems, such as a hernia, intussusception, or other medical problem. Further testing may be needed if the diagnosis is unclear.
