The human gallbladder may be small, but its role in digestion is substantial. It stores and concentrates bile, releasing it into the small intestine when fatty foods are consumed. Yet, people often wonder: what is the size and weight of the gallbladder, and how do these characteristics relate to its function—or to health issues like gallstones or obesity?
In this detailed article, we’ll cover:
-
How much a gallbladder weighs in grams and kilograms
-
How gallbladder size and weight differ among individuals
-
Gallstones and their effect on gallbladder weight
-
Signs of gallbladder trouble
-
Whether weight loss is easier or harder after removal
This guide uses data from authoritative sources like NCBI, Healthline, and WebMD to ensure accuracy.
📏 Gallbladder Size and Weight: A Breakdown
What is the size and weight of the gallbladder?
The average gallbladder in a healthy adult measures:
-
Length: 7.6 to 10.2 cm (3–4 inches)
-
Diameter: 2.5 to 5 cm (1–2 inches)
-
Volume: Can hold 50 to 70 ml of bile
-
Weight (empty): ~40 to 50 grams (1.4 to 1.8 oz)
-
Weight (full): Up to 80 grams (2.8 oz)
-
In kilograms: 0.04–0.08 kg
-
In grams: 40–80 g
-
How much does a female gallbladder weigh?
Typically slightly less than males—averaging 35 to 70 grams.
These measurements vary based on age, gender, body composition, and underlying health.
🧬 Gallbladder Function: Why Size Matters
The gallbladder’s primary role is storing bile—produced by the liver—until it’s needed to break down dietary fats. During digestion, particularly after consuming high-fat meals, the gallbladder contracts, releasing bile through the common bile duct into the duodenum (the first part of the small intestine).
Here are the top 10 functions of the gallbladder:
-
Stores bile
-
Concentrates bile by absorbing water
-
Releases bile during digestion
-
Facilitates fat absorption
-
Supports cholesterol balance
-
Assists in vitamin A, D, E, K absorption
-
Neutralizes stomach acid in the intestine
-
Prevents bile reflux
-
Coordinates with liver for bile delivery
-
Responds to hormonal triggers (CCK)

⚖️ Gallbladder Weight with Gallstones
How much does a gallbladder with stones weigh?
Gallstones can significantly increase the gallbladder’s weight depending on their size, number, and composition. An empty gallbladder might weigh 30–40 grams, but with stones, it could weigh over 100 grams in severe cases.
| Stone Size | Estimated Added Weight |
|---|---|
| Small (100–200 stones) | 3–10 grams |
| Medium (20–50 stones) | 10–50 grams |
| Large (1–5 stones) | 50–100 grams |
Which size of gallbladder stone is dangerous?
Stones larger than 2 cm are most concerning. According to ScienceDirect, such stones are more likely to cause:
-
Duct obstruction
-
Cholecystitis
-
Pancreatitis
⚠️ What Are the First Signs of a Bad Gallbladder?
Recognizing early symptoms can help prevent complications.
What are the first signs of a bad gallbladder?
-
Pain in the upper right abdomen (especially after eating fatty foods)
-
Nausea and vomiting
-
Bloating or belching
-
Fever or chills
-
Jaundice (yellowing skin or eyes)
A chronically inflamed gallbladder may also lead to gallbladder polyps or scar tissue, affecting digestion and overall function.
🏥 Gallbladder Surgery: Will You Lose Weight?
Will I lose weight after gallbladder removal?
Some individuals report modest weight loss after surgery due to:
-
A transition to a low-fat recovery diet
-
Better portion control
-
Reduced intake of fried or greasy foods
However, the relationship isn’t always direct. For some, eating becomes more challenging initially due to digestive sensitivity.
How hard is it to lose weight without a gallbladder?
Weight loss is still possible without a gallbladder, but the body no longer stores bile. Instead, bile flows directly into the intestine, which can cause:
-
Irritation
-
Loose stools
-
Fat malabsorption
To manage weight and digestion:
-
Stick to a high-fiber, low-fat diet
-
Eat smaller, more frequent meals
-
Avoid high-fat, fried, or spicy foods
-
Increase hydration and physical activity

🥗 Recovery Tips & Gallbladder-Friendly Diet
After removal (cholecystectomy), most patients recover in 4–6 weeks. However, digestive adjustments may take longer.
Post-op dietary tips:
-
Start with clear liquids → broth, tea
-
Gradually reintroduce soft foods → applesauce, rice
-
Transition to normal meals over time
-
Prioritize lean proteins and whole grains
-
Limit sugar and high-fat foods
-
Avoid alcohol for several weeks
