Your gallbladder is a storage unit, not an essential organ

In short: Most people carry gallstones without ever feeling a single symptom. This small, pear-shaped sac beneath your liver acts as a reservoir for bile, concentrating the fluid to help digest fats. Because it isn't strictly necessary for life, its removal is often a straightforward solution to chronic pain.

The gallbladder, or cholecyst, is a hollow organ that receives bile from the liver via the common hepatic duct. It stores and concentrates this fluid before releasing it into the small intestine through the common bile duct. Anatomically, it sits in a shallow depression beneath the right lobe of the liver. In adults, it typically measures 7 to 10 centimeters in length and about 4 centimeters in diameter, with a storage capacity of roughly 50 milliliters.

The primary issue associated with this organ is gallstones—pebble-like objects formed from undissolved material, usually cholesterol or bilirubin (a byproduct of hemoglobin breakdown). While many people have stones asymptomatically, they can cause 'biliary colic' if they block a bile duct. This manifests as severe, constant pain in the upper right abdomen or middle of the tummy, often lasting longer than 30 minutes and accompanied by nausea or vomiting.

Complications arise when these stones lead to inflammation (cholecystitis), pancreatitis, or jaundice—a condition where skin and eyes turn yellow due to bile backup. Because the gallbladder is not essential, the standard treatment for symptomatic stones or complications is a cholecystectomy (surgical removal). For stones specifically in the common bile duct, doctors may use ERCP, a procedure involving an endoscope passed through the mouth to widen the duct and clear the blockage.

Risk factors for developing these stones include being over 40, female gender, obesity, rapid weight loss, or conditions like diabetes. While rare, some individuals are born with gallbladder hypoplasia (underdeveloped organs) or agenesis (missing organs), which can present as chronic pain in later life and require specialized surgical management due to high risks of fibrosis.
