You wake at 1 a.m. with a deep, steady ache under your right ribs after a rich dinner. It hurts to breathe in. You feel a bit sick, and nothing you do settles it. Is this just indigestion-or the start of a gallstone problem? Here’s how to tell, what to do tonight, and what to ask your GP in Australia this week.
Short on time? Start here.
Use this simple flow to make sense of that belly pain and plan your next move.
Map the pain
Scan for triggers and context
Check for danger signs
If any of these are present, don’t wait it out-use urgent care or emergency services.
Try safe symptom relief (if you’re otherwise well)
Book the right tests
Plan the fix
What not to do: Don’t ignore fever or jaundice, don’t fast for long if you’re diabetic, don’t self-start old antibiotics, and don’t push through severe pain because it “might pass.”
Australia-specific tip: Your GP is the first stop for ultrasound and bloods. If you’re very uncomfortable tonight but stable, after-hours GP clinics and urgent care centres can assess and organise imaging. Go straight to emergency if red flags are present.
Stories are easier to recognise than lists. See which one matches you.
Classic biliary colic (gallstones): After fish and chips, a dull, rising ache under the right ribs builds over 30-45 minutes, peaks, and holds steady for an hour or two. You pace, feel nauseous, and can’t get comfy. Breathing in hurts under the right ribs. Then it fades, leaving you tired but okay.
Acute cholecystitis (inflamed gallbladder): Like biliary colic, but the pain doesn’t let up and you feel feverish or shivery. Pressing under the right ribs is sharp, and you guard the area. This needs urgent assessment.
Stone in the common bile duct (choledocholithiasis/cholangitis): Pain similar to biliary colic, plus jaundice (yellow eyes), dark urine, sometimes fever. When infection sets in (cholangitis), you feel very unwell. This is an emergency.
Gallstone pancreatitis: Severe upper belly pain straight through to the back, worse lying flat, often with vomiting. You feel wiped out and can’t get comfortable. Go to emergency.
Not gallstones-common lookalikes:
Checklist: Does this sound like gallstones? Tick the boxes that fit right now:
If you checked 4 or more, your story fits gallstones symptoms pretty well-book an ultrasound via your GP. Any red flag lifts this from “maybe” to “assess now.”
Quick decision guide (plain language):
Special groups worth a separate note:
Evidence notes: The patterns above match guidance from RACGP clinical reviews, NICE (UK) gallstone disease guideline (updated 2023), and the American College of Gastroenterology (2021). Ultrasound is the first-line test; HIDA is useful when ultrasound is equivocal for cholecystitis. Bloods help spot complications like bile duct stones or pancreatitis.
Common follow-up questions people ask once gallstones are on the radar.
Can gallstones cause bloating or diarrhoea? During attacks, nausea is common; some people get loose, pale, or greasy stools if bile flow is blocked. If your stools are persistently pale or greasy, see your GP-this can signal a duct problem.
Will stones show on CT? Often not. CT can miss cholesterol stones. Ultrasound is better for the gallbladder. MRCP is excellent for bile ducts when needed.
Can I “pass” a gallstone? Stones don’t pass from the gallbladder into the gut on their own; they can slip into the common bile duct. A small stone may pass into the bowel, causing brief jaundice or pancreatitis on the way. That’s why even small stones aren’t “safe.”
Are smaller stones safer? No. Smaller stones are actually more likely to migrate into the duct and irritate the pancreas. This is one reason guidelines often recommend surgery after clear symptomatic attacks.
Do I need surgery after one attack? Many people who have one attack will have another within months. NICE and ACG suggest offering laparoscopic cholecystectomy for symptomatic gallstones to prevent complications, especially if attacks are severe or recurrent. Your surgeon will weigh your risks and preferences.
Is there a diet that “dissolves” stones? No proven diet dissolves stones. A lighter, lower-fat plan may reduce attacks while you’re waiting for surgery. Steady weight loss beats crash diets.
Do home “gallbladder cleanses” work? No credible evidence, and they can trigger severe pain or pancreatitis. Major guidelines advise against them.
Could this be heart-related instead? Upper abdominal pain can be cardiac-especially in older adults or those with risk factors. If pain comes with breathlessness, sweating, or spreads to the jaw/arm, get urgent help.
What if my ultrasound is normal but the pain matches? Two options: repeat imaging during or soon after an attack, or consider a HIDA scan to check gallbladder function. Your GP may also look for other causes (ulcer, reflux, pancreas).
What if I’ve had my gallbladder removed and get similar pain? Rarely, a stone remains in the duct, or the sphincter muscle at the duct opening can spasm. Get checked-bloods and imaging can sort it out.
Are GLP-1 weight-loss injections a problem? These medicines are linked with a small increase in gallbladder events, especially with rapid weight loss. Don’t stop on your own-raise symptoms with your prescriber.
Can kids get gallstones? It’s uncommon but happens, especially with certain blood conditions or obesity. Paediatric assessment is important.
Next steps and troubleshooting by scenario
It fits biliary colic and I’m okay now: Book your GP within 24-48 hours. Ask for an abdominal ultrasound (gallbladder and bile ducts) and bloods (LFTs, bilirubin, lipase). Keep meals low in saturated fat until you have a plan.
It’s my first attack and it was brutal: Still see your GP promptly. Strong early attacks tend to recur, and early surgical referral can save repeat ER visits.
Pregnant and in pain: Don’t wait. Get assessed. Ultrasound is safe; hydration and pain control are key. If attacks recur, surgeons may operate in the second trimester when safer.
Diabetic or immunosuppressed: Lower your threshold for urgent care. Infections are more serious and may look subtle.
On holiday or far from home: Prioritise an urgent-care assessment for persistent or severe pain. Keep notes on timing, triggers, and any fever/jaundice to speed triage.
Ultrasound negative, pain classic: Ask about repeat ultrasound during symptoms, a HIDA scan, or MRCP if labs suggest duct involvement. Consider reflux/ulcer testing if the pattern doesn’t fully fit.
Waiting for surgery: Stick with modest-fat meals, avoid known triggers, and keep rescue pain relief on hand as advised by your doctor. Sudden fever or jaundice while waiting means urgent reassessment.
How sure can you be at home? You can’t diagnose conclusively without imaging, but the pattern is powerful. A steady, right-upper-quadrant ache after fatty food that lasts up to a few hours and recurs at night is very suggestive. The moment fever, jaundice, or unrelenting pain enters the picture, the conversation changes from “maybe gallstones” to “must be checked now.”
Credibility snapshot (no links): This guide reflects patterns and recommendations from the Royal Australian College of General Practitioners, NICE (UK) Gallstone Disease guideline (latest update 2023), the American College of Gastroenterology guideline on gallstone disease (2021), and standard emergency care pathways used across Australia. The Australian Institute of Health and Welfare reports gallbladder and biliary disease as a common reason for hospitalisation; most people do well with timely imaging and, when needed, laparoscopic surgery.
