How Much Does the Gallbladder Organ Weigh? Average Weight and More

Understanding Your Gallbladder and What It Weighs

The gallbladder is a small, pear-shaped organ that plays an important role in digestion. Situated just under the liver, the gallbladder stores and concentrates bile, a liquid produced by the liver that helps break down fats during digestion. But despite its usefulness, many people don't know basic facts about their gallbladder including how much does a gallbladder weigh.

What Is the Function of the Gallbladder?

The gallbladder plays a key role in the digestion of fats. After food is eaten, the gallbladder releases bile through ducts into the small intestine to help break down fats. Between meals, the gallbladder stores and concentrates bile, ready to release it when needed next time you eat.

So even though the gallbladder itself does not produce bile, it stores and concentrates bile produced by the liver. This allows the bile to become more potent so it can effectively break down fatty foods. Without a functioning gallbladder, the bile released after eating would be more diluted and less effective at digesting fats.

What Does a Healthy Gallbladder Look Like?

In a healthy adult, the gallbladder is typically a 3 - 4 inch sac that rests just underneath the liver. It is normally greenish-blue or maroon in color with a pear shape to it. The gallbladder tapers as it connects to the common bile duct and cystic ducts which carry bile between the gallbladder, liver, and small intestine.

The gallbladder wall has three layers. The innermost mucosal layer secretes mucus and enzymes and absorbs water and salts from bile. A muscular middle layer allows the gallbladder to contract and empty bile. Finally, the outer protective serosa layer consists of connective tissue that holds the gallbladder in place beneath the liver.

How Much Bile Does the Gallbladder Hold?

Even though the gallbladder is small, it can hold a surprisingly large amount of bile. Normally the gallbladder will hold about 50 mL or 1.7 fluid ounces when fully expanded. However this can increase to up to 60 mL or over 2 fluid ounces after a fatty meal when extra bile is released by the liver and stored in the gallbladder.

Determining the Weight of the Gallbladder

So how much does a gallbladder weigh? An average healthy gallbladder weighs approximately 27 grams or 0.95 ounces. However the weight can vary from person to person with normal gallbladder weights ranging from around 19 grams to greater than 31 grams.

Factors Affecting Gallbladder Weight

Many different factors can cause the weight of a gallbladder to increase or decrease including:

• Size - Larger gallbladders will weigh more than smaller ones
• Genetics - Some people inherit naturally heavier or lighter gallbladders
• Age - Gallbladder weight increases slowly with age
• Gender - Male gallbladders are generally heavier than female ones
• Diet and Lifestyle - Diets high in fat can lead to heavier gallbladders
• Disease States - Diseased gallbladders may be enlarged and weigh more
• Post-Surgery Changes - Gallbladder weights are lower after draining bile or removing stones

How Gallbladder Weight Compares to Other Organs

To better understand gallbladder weight, it helps to compare it to the weights of other human organs and tissues in the body:

• Brain: Approximately 1,400 grams or 3.1 pounds
• Liver: Approximately 1,500 grams or 3.3 pounds
• Skin: Around 3,800 grams or 8.4 pounds
• Kidneys: Roughly 320 grams or 0.7 pounds combined weight
• Heart: Male 278 grams, Female 252 grams on average

As shown above, the gallbladder is tiny compared to vital major organs like the brain, liver, skin, kidneys and heart. But despite its small size, the gallbladder still serves an important digestive role especially when it comes to processing fats.

When the Gallbladder Is Removed

In some cases, the gallbladder may need to be removed completely in a procedure called a cholecystectomy. This is often done laparoscopically through several minor incisions or sometimes through one larger open incision if needed.

Gallbladder removal is most often required when gallstones cause recurrent pain attacks or dangerous complications like infection or blockage of bile flow. Sometimes the gallbladder is taken out to treat gallbladder cancer or due to traumatic injury.

Living Without a Gallbladder

Fortunately, people can often live normal healthy lives without their gallbladders. Losing this organ does require some lifestyle adjustments though as the body can no longer store and concentrate bile.

After gallbladder removal, bile simply drips from the liver constantly into the small intestine. Some people notice more frequent bowel movements or looser stools after eating fatty foods. But dietary changes like eating smaller lower fat meals or taking bile salts with meals can often help manage these issues.

Over 700,000 gallbladders are removed from patients each year in the U.S. alone. Given how common this procedure is, most people are able to adapt well to day-to-day life without their gallbladder.
