Gallstones. Cutaway computer artwork showing gallstones (blue, round, lower left) in a human gall bladder (oval, sac-like, lower left). The gall bladder is a small muscular sac lying under the liver (top left). It expels bile (a fat emulsifier) into the intestines (not shown) through the bile duct (tube, centre left). Gallstones are hard deposits of salts or cholesterol that form in the gall bladder when the chemical composition of bile is upset. They are most common in women, the elderly and the obese. They usually cause no symptoms unless one becomes stuck in the bile duct, which can lead to acute pain, jaundice and infection. Surgical removal of the gall bladder is sometimes necessary.
