5 Signs of a Gallbladder Problem Most People Mistake for Indigestion

By Mike Harper · August 11, 2026

You assumed it was something you ate. You took an antacid. It didn’t help. The pain isn’t in your stomach — it’s under your ribs on the right side, and it may be your gallbladder.

Gallbladder disease affects roughly 20 million Americans, and the symptoms overlap so heavily with acid reflux and ordinary indigestion that many people treat themselves with antacids for months before discovering the real cause. The gallbladder — a small organ tucked beneath the liver — stores bile and releases it to help digest fat. When gallstones block the bile duct, the result is pain that can mimic almost every common digestive condition.

The pain is under your right rib cage — not behind your breastbone. Indigestion and acid reflux produce a burning sensation that’s typically centered behind the breastbone or in the upper middle abdomen. Gallbladder pain settles in the upper right side of the abdomen, just below the rib cage, and often radiates to the back or right shoulder blade. If the discomfort is consistently on the right side, the source is more likely your gallbladder than your stomach.

Antacids don’t help — and neither does changing position. One of the clearest diagnostic clues is response to treatment. Acid reflux usually improves with antacids, dietary changes, or simply sitting upright. Gallbladder pain doesn’t respond to antacids, posture changes, or bowel movements. If you’ve been taking Tums or Prilosec for weeks and the pain keeps coming back unchanged, the problem may not be acid at all.

The pain comes in episodes — often after fatty meals. Gallbladder attacks are frequently triggered by meals high in fat, which stimulate the gallbladder to release bile. The pain builds over 15 to 30 minutes, plateaus, and can last anywhere from 30 minutes to several hours before subsiding. The episodic pattern — fine for days, then a sudden severe episode — is characteristic. Indigestion tends to be more constant and less dramatic.

You feel nauseous after eating — even small meals. Nausea and bloating after eating are common with both conditions. But gallbladder-related nausea tends to be more persistent and is often accompanied by a sense of fullness that feels disproportionate to what you ate. If a small meal makes you feel like you ate Thanksgiving dinner, the bile system may not be processing fat efficiently.

The pain wakes you up at night. Acid reflux can worsen when lying down, but gallbladder attacks frequently strike in the middle of the night — severe enough to wake you from sleep. The pain is intense, doesn’t respond to position changes, and can last for hours. Gallbladder pain that is severe, constant, or accompanied by fever or jaundice requires urgent medical evaluation.

The risk factors include being over 40, female, overweight, having a family history of gallstones, or having lost weight rapidly. Diagnosis typically requires an abdominal ultrasound — a quick, noninvasive test that can identify gallstones in minutes. If you’ve been treating what you assumed was acid reflux and it keeps coming back despite medication, asking your doctor about your gallbladder could end months of misdiagnosis.
