A person can live a normal lifespan without a gallbladder, states Everyday Health. The gallbladder, a small organ under the liver, stores bile, a liquid the liver produces to aid fatty food digestion. The liver continues to produce sufficient bile for normal digestion after gallbladder removal.
After a person without a gallbladder eats a meal, bile leaks from the liver directly into the small intestine, explains Everyday Health. The body adjusts to the missing organ, but some people may need to modify their diets. To minimize gas, bloating and discomfort, patients should avoid fried foods, processed meats and high-fat dairy products for a few weeks after gallbladder surgery.
