COLIC DIAGNOSIS

Pediatricians and family physicians suspect colic in an infant who:

• has cried loudly for at least three hours a day at least three times a week for three weeks or longer
• is not hungry but cries for several hours between dinnertime and midnight
• demonstrates the clenched fists, rigidity, and other physical traits associated with colic

The baby's medical history and a parent's description of eating, sleeping, and crying patterns are used to confirm a diagnosis of colic. Physical examination and laboratory tests are used to rule out infection, intestinal blockage, and other conditions that can cause abdominal pain and other colic-like symptoms.
