Colic is a specific pattern of severe, wave-like cramping pain that occurs in both adults and infants.
Colic Pain in Adults
Colic occurs in hollow, muscle-lined organs – such as the stomach, intestines, gallbladder, kidneys, ureters, and uterus.
- Severe means it causes intense, sharp, squeezing cramps rather than a dull background ache.
- Wave-like means the pain rapidly intensifies to a sharp peak, subsides so the person feels temporary relief, and then intensifies again.
- Why It Happens: This pattern occurs when a passageway inside a hollow organ becomes blocked or irritated. The organ responds by squeezing its smooth muscles violently to push out the obstacle, resulting in sharp, repeating waves of cramping pain.
In adults, colic can be acute (a sudden episode caused by a temporary blockage like a kidney stone or gallstone) or chronic/recurrent (recurring episodes driven by underlying long-term conditions like IBS, recurrent stone formation, or endometriosis)
Colic Pain in Infants
Infantile colic refers to sharp, repeating gut cramps caused by an immature digestive system or trapped gas, leading to prolonged, inconsolable crying in an otherwise healthy baby.
Infantile colic is strictly temporary – it typically peaks around 6 weeks of age and resolves completely on its own by 3 to 4 months as the baby’s digestive tract and nervous system mature.
Where Does Colic Occur?
Colic only occurs in hollow organs structured like tubes or pouches – such as the stomach, intestines, gallbladder, bile ducts, kidneys, ureters, or uterus. Solid organs (like the liver or spleen) do not have muscular walls that squeeze in this manner, so they cannot cause colic pain.
The 4 Major Types of Colic in Adults
Depending on which hollow organ is obstructed or irritated, adult colic is categorized into four primary types:
- Intestinal Colic: Intestines squeezing against gas, food blockages, or IBS.
- Biliary Colic: Gallbladder squeezing against a gallstone blocking the bile duct.
- Renal Colic: Ureter squeezing against a kidney stone.
- Uterine Colic (Dysmenorrhea): Uterus squeezing violently to shed its lining during periods.
Because every form of acute adult colic shares the exact same biological mechanism – an irritated hollow organ combined with a squeezing smooth muscle – the first preferred line of treatment relies on a dual combination of NSAID (Non-Steroidal Anti-Inflammatory Drug) and Anti-Spasmodic medication.
