Upper right abdominal pain can feel deceptively simple—“something under my ribs hurts”—yet the right upper quadrant sits at a crossroads of digestion, breathing, and circulation. The gallbladder, liver, stomach and esophagus, bile ducts, and even the right lung and diaphragm can all send signals to the same neighborhood. The good news is that pain patterns often carry clues: when it starts, how it behaves, and what travels with it (nausea, fever, jaundice, burning reflux, or shoulder pain) can narrow the likely causes before any test is done. This guide walks you through the most common explanations—gallbladder issues, liver-related problems, and reflux or stomach irritation—plus the red flags that should change your timeline from “watch and plan” to “get urgent care.”
Quick Overview
- Notice the pattern: meal-related, wave-like pain often points toward the gallbladder, while burning that worsens when lying down suggests reflux.
- Pair location with “travel”: pain that radiates to the right shoulder blade can fit biliary pain, while central burning can fit acid reflux.
- Treat jaundice, fever, faintness, or persistent severe pain as urgent signals, not wait-and-see symptoms.
- Keep a 24–48 hour symptom log (timing, triggers, duration, severity 0–10, stool and urine color) to speed up accurate evaluation.

Upper right pain basics and body clues
“Upper right abdominal pain” usually means discomfort under the right rib cage, sometimes extending to the center upper abdomen. That area is busy: the liver sits there, the gallbladder tucks beneath it, and the bile ducts and duodenum (first part of the small intestine) run nearby. The diaphragm and lower right lung can also refer pain downward, and the right kidney, ribs, and abdominal wall muscles can contribute pain that feels “internal.”
Because several structures share nerves, the quality of pain matters as much as the location:
- Cramping or wave-like pain (colicky) that builds and eases can suggest spasms in a hollow organ, such as the gallbladder or bile ducts.
- Steady, intensifying pain that does not let up raises concern for inflammation (for example, an irritated gallbladder) or another process that needs timely evaluation.
- Burning or hot discomfort behind the breastbone or in the upper abdomen often fits reflux or acid-related irritation.
- Sharp pain on deep breaths or coughing can point toward the diaphragm, lung lining, or even gallbladder inflammation that becomes more noticeable when the diaphragm moves.
Pay attention to timing and triggers:
- After meals (especially heavy or fatty meals): more suggestive of gallbladder or acid-related causes.
- Worse when lying down or bending: often reflux.
- Worse with movement, twisting, pressing on a rib, or after exercise: can be musculoskeletal, though this does not fully exclude internal causes.
A two-minute self-check that helps clinicians
If the pain is not an emergency, write down:
- Onset: sudden vs gradual; first episode vs recurring
- Duration: minutes, hours, or constant for a day or more
- Severity: 0–10 scale and whether it prevents normal activity
- Radiation: right shoulder blade, back, chest, or down the abdomen
- Associated symptoms: nausea, vomiting, fever, chills, heartburn, bloating
- Color clues: dark urine, pale stools, or yellow eyes/skin
- What changes it: eating, antacids, bowel movement, position, or pain medicine
Patterns do not diagnose you, but they can strongly guide which causes are most likely—and which tests are most useful first.
Gallbladder pain patterns and triggers
Gallbladder-related pain is one of the most common reasons for right upper quadrant discomfort. The gallbladder stores bile and squeezes it out when you eat—especially when a meal contains fat. If a gallstone (or thick bile “sludge”) temporarily blocks the outflow, you can get pain that is memorable and repetitive.
Classic biliary colic (a gallbladder “attack”)
Many people describe:
- A deep ache or pressure under the right ribs or in the center upper abdomen
- Pain that builds over 15–60 minutes, then holds steady
- Duration often 30 minutes to a few hours
- Nausea is common; vomiting can happen
- Pain may radiate to the right shoulder blade or mid-back
A key clue is the trigger: symptoms often start within a few hours after a rich meal or at night after a late dinner. The name “colic” is misleading because the pain can feel steady once it peaks.
When it becomes more urgent: inflammation and complications
Pain is more concerning when it suggests inflammation or a blocked duct that is not clearing:
- Acute cholecystitis (inflamed gallbladder): pain tends to be constant, lasts more than 6 hours, and may come with fever, significant tenderness, and ongoing vomiting.
- Stone in the common bile duct: may cause jaundice (yellow skin or eyes), dark urine, and pale stools because bile cannot reach the intestine normally.
- Ascending cholangitis (infected bile ducts): classically combines fever, right upper abdominal pain, and jaundice—this is a medical emergency.
- Gallstone pancreatitis: can cause severe upper abdominal pain (often central) that may radiate to the back, commonly with persistent vomiting.
Risk factors that make gallbladder causes more likely
Gallstones are more common with:
- Rapid weight loss or very-low-calorie dieting
- Pregnancy and the postpartum period
- Obesity or central weight gain
- Insulin resistance and high triglycerides
- Family history, and increasing age
What you can do safely while arranging evaluation
If symptoms are mild and you are stable:
- Choose small, lower-fat meals for a few days (think grilled lean protein, soups, oats, rice, bananas).
- Avoid alcohol during an active flare.
- Use pain medicine cautiously: avoid exceeding label doses, and do not combine multiple products that contain acetaminophen.
Even if the pain resolves, recurring attacks are a reason to seek follow-up, because repeated obstruction can escalate into infection or pancreatitis.
Liver causes and warning signs
The liver is often blamed for right upper abdominal pain, but it is worth knowing a practical truth: many liver conditions are silent until they are advanced or until the liver’s outer capsule becomes stretched or inflamed. When liver-related pain is present, it is often described as a dull ache, pressure, or fullness under the right ribs rather than a sharp cramp.
Situations where the liver is a more likely source
Consider liver-related causes when right upper pain appears with systemic symptoms such as:
- Fatigue, low appetite, nausea, or “flu-like” feelings
- Fever without a clear stomach trigger
- Jaundice, dark urine, pale stool, or widespread itching
- A sense of abdominal fullness or swelling
- New bruising tendency or mental fog (more concerning signs)
Potential liver-related explanations include:
- Hepatitis (viral, medication-related, alcohol-related, autoimmune): can cause malaise and tenderness, sometimes with jaundice.
- Congestion of the liver from heart strain (for example, significant right-sided heart failure): may cause a heavy sensation in the right upper abdomen, often with swelling in the legs and shortness of breath.
- Liver abscess (a pocket of infection): may cause fever and localized pain and requires urgent care.
- Cysts, tumors, or vascular problems: can cause stretching discomfort or a persistent ache, especially when the liver capsule is irritated.
Fatty liver: common, often quiet
Metabolic dysfunction-associated steatotic liver disease (often still called “fatty liver”) is extremely common and frequently causes no pain at all. Some people report vague right upper discomfort, but the more typical path is that it’s discovered on blood tests or imaging done for another reason. Because symptoms are unreliable, risk factors matter: central weight gain, type 2 diabetes, high triglycerides, and sleep apnea can raise suspicion even when pain is mild.
What to avoid if liver irritation is possible
When liver involvement is on the table, the safest “pause” steps are:
- Avoid alcohol until you have clarity
- Do not exceed recommended acetaminophen doses, and avoid combining products that contain it
- Be cautious with new supplements and “detox” products—some can inflame the liver
- Bring a complete medication list to your clinician, including herbs and over-the-counter products
Liver-related pain is rarely something to self-diagnose; the right approach is to pair symptoms with targeted blood tests and, when appropriate, imaging.
Reflux and stomach causes that mimic
Acid reflux and upper-stomach irritation can create pain that overlaps with gallbladder and liver discomfort—especially because burning or pressure in the upper abdomen can drift to the right side. This is one reason people can feel stuck between “Is it my gallbladder or just reflux?”
Reflux patterns that fit the story
Reflux (GERD) is more likely when discomfort is:
- Burning in the upper abdomen or behind the breastbone
- Worse after large meals, late-night eating, bending, or lying flat
- Paired with sour taste, regurgitation, hoarseness, chronic cough, or throat clearing
- Improved by antacids or avoiding triggers
Reflux can sometimes present as pressure rather than burn. Some people feel it mainly in the upper abdomen, not the chest.
Gastritis and peptic ulcer disease
Inflammation of the stomach lining or an ulcer can cause:
- A gnawing or aching upper abdominal pain
- Symptoms that relate to meals (either worse right after eating or worse when the stomach is empty)
- Bloating, early fullness, nausea
- A history of frequent NSAID use (ibuprofen, naproxen) increases risk
A crucial safety note: black, tarry stools, vomiting blood, severe weakness, or fainting can signal gastrointestinal bleeding and needs urgent evaluation.
A practical, low-risk reflux plan for 7–14 days
If your symptoms fit reflux and you are otherwise stable, these steps are often worth trying while you arrange care:
- Stop eating 2–3 hours before lying down.
- Keep meals smaller and more evenly spaced (avoid the “one huge dinner” pattern).
- Identify and reduce common triggers: alcohol, mint, chocolate, fried foods, very spicy foods, and high-acid beverages can be triggers for some people.
- If nighttime symptoms dominate, elevate the head of the bed (a wedge pillow or bed risers tends to work better than extra pillows).
- Consider short-term over-the-counter options as directed on the label (antacids for quick relief; alginate-based products after meals; or an H2 blocker).
When reflux-like symptoms need a different timeline
Seek prompt medical guidance if you have progressive trouble swallowing, unexplained weight loss, persistent vomiting, anemia, or pain that reliably wakes you at night and is not responding to basic measures. “Reflux” should improve with targeted habits; if it does not, the diagnosis may be different—or you may need a more structured treatment plan.
Symptoms that mean urgent evaluation
Right upper abdominal pain ranges from benign to time-sensitive. The safest approach is to treat certain accompanying symptoms as “do not wait” signals. If any of the following are present, urgent care (same-day evaluation or emergency services) is the prudent move:
Red flags that should change your plan today
- Severe, escalating pain (especially if it prevents you from finding a comfortable position)
- Pain that is constant for more than 6 hours, particularly after a suspected gallbladder-type attack
- Fever (about 38°C / 100.4°F or higher), shaking chills, or appearing ill
- Jaundice (yellow eyes or skin), dark urine, or pale stools
- Repeated vomiting, inability to keep fluids down, or signs of dehydration (very dark urine, dizziness, dry mouth)
- Chest pressure, shortness of breath, or pain radiating to the arm or jaw (upper abdominal discomfort can occasionally be confused with heart-related symptoms)
- Black, tarry stool or vomiting blood
- New confusion, extreme drowsiness, or fainting
- Pregnancy, significant immune suppression, or a known history of cirrhosis (lower threshold for urgent assessment)
A classic emergency pattern to know
A combination of right upper pain + fever + jaundice is especially concerning because it can reflect an infected, obstructed bile duct. This is not a condition to watch at home.
What to do on the way to evaluation
If urgent evaluation is needed:
- Do not “test it” with a heavy meal.
- Avoid alcohol and avoid taking extra doses of pain medicine “to push through.”
- Bring a list of medications and supplements, and note your last meal.
- If you are dizzy, faint, or in severe pain, do not drive yourself.
If you are stable and none of the red flags apply, it is still reasonable to seek timely outpatient care—especially if episodes repeat, your pain pattern is changing, or symptoms are gradually intensifying.
Diagnosis and a practical next-step plan
When clinicians evaluate upper right abdominal pain, the goal is not just to label the pain, but to separate urgent causes from treatable chronic ones, and to choose tests that match the most likely anatomy involved.
What your clinician will usually ask
Expect focused questions about:
- Exact location and whether pain radiates to the back or shoulder
- Timing: minutes vs hours, and whether it follows meals
- Stool and urine color changes
- Medication and supplement use (including acetaminophen totals and NSAIDs)
- Alcohol intake patterns (daily use vs binge episodes)
- Pregnancy possibility and prior abdominal surgeries
- Prior episodes and what helped
A careful abdominal exam can identify localized tenderness, guarding, or pain that increases with a deep breath. Your vital signs—especially fever, heart rate, and blood pressure—matter as much as the pain description.
Common first-line tests and what they look for
- Blood tests: liver enzymes, bilirubin, inflammation markers, and sometimes pancreatic enzymes help identify bile duct obstruction, hepatitis patterns, or pancreatitis.
- Ultrasound: often the first imaging choice for suspected gallstones or gallbladder inflammation; it can also show bile duct dilation and some liver changes.
- Additional imaging (based on the story): CT can broaden the search when the diagnosis is unclear; specialized imaging can evaluate the bile ducts more closely.
- Upper endoscopy: considered when symptoms point strongly to reflux complications, ulcers, bleeding, or persistent upper abdominal pain with alarm features.
Your “do this now” plan if you are stable
While you arrange care, these steps are practical and generally low-risk:
- Track symptoms for 2–3 days: timing, triggers, duration, pain score, nausea, fever, stool and urine color, and any relief from antacids or dietary changes.
- Choose a gentle food pattern: small meals; limit fried and high-fat foods; reduce late-night eating.
- Hydrate steadily: frequent sips are better than large gulps if nausea is present.
- Use medications responsibly: follow label dosing, avoid doubling products with the same active ingredient, and stop NSAIDs if they worsen burning pain or nausea.
- Set a clear threshold for escalation: if pain becomes constant and severe, fever appears, jaundice develops, or vomiting prevents hydration, switch from “monitor” to urgent evaluation.
Prevention mindset for recurring symptoms
If episodes repeat, focus on the long game:
- Aim for gradual weight changes rather than rapid weight loss
- Emphasize fiber-rich foods and balanced fats rather than very high-fat meals
- Address reflux drivers: late meals, large portions, and lying down soon after eating
- Treat constipation when present, because bowel pressure can amplify upper abdominal discomfort
A clear pattern, a concise symptom log, and timely testing often turn a frustrating mystery into a focused, effective plan.
