The gallbladder is a storage organ for bile which is produced by the liver. Bile helps in the digestion of fats in the intestines. During fasting, the gallbladder receives bile from the liver and concentrates this bile. When a fatty meal is consumed, this concentrated bile is released into the intestines to help in fat digestion and absorption. The most common disease affecting the gallbladder is the formation of stones in the gallbladder. There are 3 types of gallstones, namely cholesterol stones, pigment stones and mixed stones.
Cholesterol stones form as result of excessive amount of cholesterol in bile. Pigment stones form as result of breakdown in the red blood cells in the body. The presence of stones in the gallbladder affects the normal functions of the gallbladder, resulting in feeling of indigestion after food intake. Prolonged low grade infection of the gallbladder can occur due to the gallstone. Large gallbladder stones can block the opening of the gallbladder. Smaller gallbladder stones can migrate out the gallbladder and block the bile duct, causing several symptoms and complications.
