GallBladder Function


Gallbladder removal is one of the most commonly performed surgical procedures in the United States. Gallbladder surgery is almost always performed laparoscopically. The medical name for this procedure is Laparoscopic Cholecystectomy.

What is the Gallbladder?

  • The gallbladder is a pear-shaped organ that rests beneath the right side of the liver.
  • Its main purpose is to collect and concentrate a digestive liquid (bile) produced by the liver. Once bile is made by the liver, it gets stored in the gallbladder. When you eat, the stomach sends a signal to the gallbladder. The gallbladder contracts, bile is expelled and moves down the main common duct to enter the intestine. Once there, bile mixes with food, aiding in digestion.
  • Removal of the gallbladder is not associated with any impairment of digestion in most people

What are Gallstones made of?

Gallstones are small, pebble-like substances that develop in the gallbladder. The gallbladder is a small, pear-shaped sac located below your liver in the right upper abdomen. Gallstones form when liquid stored in the gallbladder hardens into pieces of stone-like material. The liquid—called bile—helps the body digest fats. Bile is made in the liver, then stored in the gallbladder until the body needs it. The gallbladder contracts and pushes the bile into a tube—called the common bile duct—that carries it to the small intestine, where it helps with digestion.

Bile contains water, cholesterol, fats, bile salts, proteins, and bilirubin—a waste product. Bile salts break up fat, and bilirubin gives bile and stool a yellowish-brown color. If the liquid bile contains too much cholesterol, bile salts, or bilirubin, it can harden into gallstones.

The two types of gallstones are cholesterol stones and pigment stones. Cholesterol stones are usually yellow-green and are made primarily of hardened cholesterol. They account for about 80 percent of gallstones. Pigment stones are small, dark stones made of bilirubin. Gallstones can be as small as a grain of sand or as large as a golf ball. The gallbladder can develop just one large stone, hundreds of tiny stones, or a combination of the two.


Why did I get Gallstones?

No one knows exactly why people get gallstones. We know there are certain risk factors for developing gallstones. They are:

  • women—especially women who are pregnant, use hormone replacement therapy, or take birth control pills
  • people over age 60
  • American Indians
  • Mexican Americans
  • overweight or obese men and women
  • people who fast or lose a lot of weight quickly
  • people with a family history of gallstones
  • people with diabetes
  • people who take cholesterol-lowering drugs

Do you need your Gallbladder?

You gallbladder is a storage device, essentially a reservoir, designed to concentrate bile, which is produced by your liver. When you eat, the gallbladder contracts, and pushes out its stored bile into your intestine. The bile helps dissolve the fatty component of foods. Without your gallbladder, your liver will still produce bile but it will no longer be stored in the gallbladder. The bile will constantly slowly enter your intestine.

Fortunately, the gallbladder is an organ people can live without. Your liver produces enough bile to digest a normal diet. Once the gallbladder is removed, bile flows out of the liver through the hepatic ducts into the common bile duct and directly into the small intestine, instead of being stored in the gallbladder. Because now the bile flows into the small intestine more often, softer and more frequent stools can occur in about 1 percent of people. These changes are usually temporary, but talk with your health care provider if they persist.

What causes Gallbladder Problems?

  1. Gallbladder problems are usually caused by the presence of gallstones: small hard stones consisting primarily of cholesterol and bile salts that form in the gallbladder.
  2. It is uncertain why some people form gallstones. There are certain risk factors. They are commonly referred to as the four Fs: Females, Forty, Fertile, and Fat. Thus, gallstones tend to form in women, during pregnancy, with weight gain, and as people age.
  3. There is no known means to prevent gallstones.
  4. Many people discover that they have gallstones during tests for other medical conditions. Gallstones that are not and have not cause symptoms or problems generally do not need to be removed.
  5. Gallstones can cause symptoms in many ways :
    1. when they block the block the flow of bile out of the gallbladder, the gallbladder swells which can result in:
    2. Sharp abdominal pain (usually below your liver on the right upper side of your belly or just below your breast bone)
    3. Pain may also be felt in your back or R upper shoulder
    4. Bloating and / or abdominal distension
    5. Nausea and / or vomiting
    6. Indigestion
    7. If the gallstone becomes lodged, an infection can result
    8. Fever and severe abdominal pain will result along with the above symptoms
    9. Stones can also lodge and block the main common bile duct resulting in jaundice, a yellowing of the skin
    10. Stones can also irritate the pancreas and lead to pancreatitis
