About 10 to 15 percent of adults in the United States have gallstones, or roughly 25 million people, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Most never realize it.
But when a stone starts blocking a bile duct or the gallbladder becomes inflamed, the early symptoms often look and feel like ordinary indigestion or reflux.
Around 1 million Americans are diagnosed with gallstones each year, and about a quarter of them will need treatment, usually surgery.
The condition strikes women, people with obesity, pregnant patients and adults in their 40s at the highest rates, according to a peer-reviewed clinical review in the NIH StatPearls collection.

Early gallbladder pain, known clinically as biliary colic, is a steady gnawing ache in the upper right abdomen that can radiate to the back. Here are the seven signals worth taking seriously.
The 7 signs worth taking seriously
1. Right-side pain that follows a fatty meal. The pain usually starts 30 to 60 minutes after eating something rich or greasy and can last from half an hour up to six hours, according to Atlantic Health System. It often radiates to the back or the right shoulder blade.
2. Nausea and vomiting. These symptoms typically show up alongside the pain and rank among the most consistent early signs listed by both NIDDK and Atlantic Health.
3. Bloating, gas and belching after eating. Persistent post-meal discomfort is one of the symptoms most easily blamed on heartburn, reflux or a passing stomach bug.

4. Sudden intolerance to greasy or fried food. If a burger or a fried breakfast reliably triggers pain or queasiness where it did not before, that can point to a gallbladder that is no longer emptying properly.
5. Fever or chills. Even a low-grade fever alongside abdominal pain may signal a serious infection or inflammation of the gallbladder, liver or pancreas, NIDDK warns.
6. Dark urine and pale, chalky stools. Tea-colored urine paired with light, clay-colored stool suggests bile is not draining as it should. It is one of the warning signs that call for prompt medical attention.
7. Yellowing of the skin or the whites of the eyes. Jaundice means bile is backing up into the bloodstream and points to a blocked duct or a more serious complication.

When gallbladder pain becomes an emergency
Fever, jaundice or chalky stool alongside abdominal pain should be treated as urgent, per NIDDK.
Atlantic Health System advises going to the emergency room if the pain is severe, lasts more than six hours, or is accompanied by fever or jaundice. Waiting risks acute cholecystitis, a serious inflammation of the gallbladder that typically requires hospitalization.
Who is at highest risk
Female sex, obesity, pregnancy and being in your 40s are the strongest risk factors for gallbladder disease, per the NIH StatPearls clinical reference. Sickle cell disease and hyperparathyroidism can also raise the odds.
Rapid weight loss, diabetes, oral contraceptives, gastric bypass surgery and certain drugs, including the newer GLP-1 medications used for diabetes and weight loss, also increase the risk, according to Atlantic Health System.

Anyone recognizing several of these signals in themselves should book an appointment with a primary care doctor rather than reach for another antacid.
When imaging confirms gallstones that are causing symptoms, cholecystectomy, the surgical removal of the gallbladder, is the standard treatment.
