Why Does Gallbladder Pain Occur on the Right Side of the Abdomen?
A clear explanation of gallstones, gallbladder infections, and why right sided abdominal pain often leads doctors to this small organ.
A Moment in the ER
Angela, a 38 year old teacher, sits quietly on the stretcher holding the right side of her upper abdomen. She tells me the pain started shortly after dinner and feels sharp beneath her ribs. It comes in waves and has already made her vomit twice tonight.
When I press gently under her right rib cage, she suddenly stops breathing in and grabs my hand.
Some pain patterns point doctors toward very specific organs.
The Gallbladder: A Small Organ With One Main Job
The gallbladder is a small storage pouch that holds bile.
It sits tucked beneath the liver on the right side of the upper abdomen. The liver constantly produces bile, a digestive fluid that helps break down fats. The gallbladder stores this bile and releases it when you eat a meal, especially one containing fat.
When the gallbladder squeezes bile into the digestive system, it helps your body digest foods like oils, butter, and other fatty meals. Most of the time this process works quietly in the background.
When Gallstones Block the Flow
Gallstones are small hardened deposits that form inside the gallbladder.
These stones develop when bile components, such as cholesterol or bile salts, crystallize and clump together. Many people have gallstones without symptoms, but problems begin when a stone temporarily blocks the flow of bile leaving the gallbladder.
When bile cannot move freely, the gallbladder contracts against the blockage. This causes sudden, intense pain called biliary colic. The pain often appears in the right upper abdomen and frequently starts after eating fatty foods.
When Gallstones Turn Into an Infection
Sometimes the blockage leads to inflammation or infection of the gallbladder.
When the gallbladder becomes inflamed, doctors call the condition cholecystitis. Patients often develop more severe pain along with fever, nausea, and vomiting. Blood tests may show elevated white blood cells, suggesting infection.
In the emergency department, ultrasound is usually the best test to evaluate the gallbladder. Ultrasound can show gallstones, thickening of the gallbladder wall, or fluid around the organ. Doctors also watch for a reaction called the Murphy sign, where pressing over the gallbladder causes sharp pain during the exam.
Why Surgery Is Often the Best Treatment
Gallbladder problems often return once they start.
While medications can sometimes help dissolve gallstones, they work slowly and are not always effective. Because of this, the most common treatment for repeated gallbladder attacks or infection is surgery to remove the gallbladder.
The surgery is called a cholecystectomy and is usually performed using small incisions with minimally invasive techniques. Most patients go home the same day or the next. The body can function normally without a gallbladder because the liver continues to produce bile for digestion.
THE BOTTOM LINE
• Gallbladder disease often causes sudden pain in the right upper abdomen, especially after fatty meals
• Gallstones can block the flow of bile and trigger severe pain called biliary colic
• When infection develops, surgery to remove the gallbladder is usually the most effective treatment
