The gallbladder is a small pouch located under the liver that stores and releases bile produced by the liver to help digest and absorb fats. Bile is released from the gallbladder after meals to break down fats into smaller components. While the gallbladder helps with fat digestion, it is not always necessary, as some people have their gallbladder removed due to gallstones or dysfunction with the ability to adapt to digesting fats without it over time.
