Gallstones are hard, pebble-like pieces of cholesterol or bilirubin that form in the gallbladder, and they are startlingly common. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) estimates they affect 10 to 15 percent of the US population, or almost 25 million people.
Most of those stones sit silently and never cause trouble. Problems begin only when a stone shifts and blocks a bile duct, and the symptoms that follow are frequently written off as heartburn, gas or a bad meal. That confusion can delay diagnosis and let serious complications develop.
Why the signs get missed
A gallbladder attack usually hits in the evening or at night, often after a heavy meal. The pain can last several hours and then ease, which is part of why people talk themselves into believing it was indigestion.
The Cleveland Clinic notes that gallstones generally cause no symptoms until they create a blockage. When they do, the picture can escalate quickly, and untreated blockages of the bile or pancreatic ducts can be fatal, according to NIDDK.

8 warning signs worth taking seriously
1. Sudden, intense pain in the upper right abdomen. This is the classic sign, known as biliary colic. NIDDK describes attacks that "usually cause pain in your upper right abdomen, sometimes lasting several hours". Cleveland Clinic says people describe it as sharp, stabbing, cramping or squeezing.
2. Pain that spreads to the right shoulder or between the shoulder blades. The Cleveland Clinic notes some people feel gallstone pain in the right arm or shoulder, or in the back between the shoulder blades. It is easy to blame on muscle tension when the abdominal pain is not front and center.
3. Nausea or vomiting, especially after fatty meals. Attacks often follow heavy meals, per NIDDK, and nausea and vomiting are among the symptoms that should prompt a call to a doctor.
4. Jaundice. A yellowish tint to the skin or the whites of the eyes signals that bile is backing up. NIDDK lists "yellowish color of your skin or whites of your eyes, called jaundice" as a reason to seek care.

5. Dark, tea-colored urine. Another sign the bile flow is blocked, listed by NIDDK alongside jaundice.
6. Pale, clay-colored stools. When bile cannot reach the intestine, stools lose their normal color. NIDDK groups this with dark urine as a warning that a duct may be obstructed.
7. Fever or chills with abdominal pain. This combination is a red flag. NIDDK warns that fever, even low-grade, or chills alongside abdominal pain "may be signs of a serious infection or inflammation of the gallbladder, liver, or pancreas." If fever and pain arrive together, this is the point to seek emergency care, not to wait it out.
8. Abdominal swelling and tenderness. Cleveland Clinic lists abdominal swelling and tenderness, sweating and a fast heart rate among the symptoms that can develop when a blockage is severe or drags on.

When indigestion becomes an emergency
The reason accurate recognition matters is what can happen next. Cleveland Clinic lists three serious complications of gallstones: cholecystitis, meaning inflammation of the gallbladder; pancreatitis, or inflammation of the pancreas; and cholangitis, an inflammation of the bile ducts.
Anyone experiencing sudden stabbing pain in the upper right abdomen or shoulder, particularly after eating, should seek medical attention right away, according to the Cleveland Clinic. People with persistent upper-abdominal symptoms that keep getting written off as heartburn or IBS should talk to a doctor rather than self-manage. A simple ultrasound can usually settle the question.
