What is biliary colic? (The name is misleading)
Biliary colic is the term used to describe the classic pain caused by gallstones. Despite the name, the pain is not colicky (wave‑like). Instead, it is a steady, dull, or sharp ache that builds to a plateau and then slowly resolves. The pain occurs when a gallstone temporarily blocks the cystic duct (the tube draining the gallbladder). The gallbladder contracts against the obstruction, causing pain. When the stone falls back, the pain stops.
Symptoms of biliary colic – pain location, radiation, triggers
Typical features of biliary colic:
- Location: Right upper quadrant (RUQ) of the abdomen, just below the ribs. May also be felt in the epigastrium (upper middle abdomen).
- Radiation: Pain may radiate to the right shoulder, right shoulder blade, or mid‑back (referred pain via the phrenic nerve).
- Trigger: Typically occurs 30‑60 minutes after a heavy, fatty meal (when the gallbladder contracts).
- Associated symptoms: Nausea, vomiting, bloating, belching, and intolerance to fatty foods.
- No fever: Biliary colic does not cause fever. Fever suggests acute cholecystitis (infection).
- No jaundice: Jaundice suggests a common bile duct stone, not simple biliary colic.
How long does biliary colic last?
Biliary colic typically lasts 15 minutes to 3‑4 hours. The pain peaks quickly and then plateaus before resolving. If pain persists for more than 6 hours, suspect acute cholecystitis (inflammation) rather than simple biliary colic. The pain resolves spontaneously when the stone falls back into the gallbladder.
Biliary colic vs acute cholecystitis – key differences
Differentiating biliary colic from acute cholecystitis is critical because cholecystitis requires antibiotics and often urgent surgery.
| Feature | Biliary colic | Acute cholecystitis |
|---|---|---|
| Pain duration | <6 hours | >6 hours, often constant |
| Fever | Absent | Present (often >38°C) |
| Nausea/vomiting | Mild to moderate | Often severe |
| Murphy’s sign (pain on palpation of RUQ) | Usually absent | Present (pain with deep inspiration) |
| White blood cell count | Normal | Elevated |
| Ultrasound findings | Gallstones only | Gallstones + gallbladder wall thickening (>4mm), pericholecystic fluid, sonographic Murphy’s sign |
How is biliary colic diagnosed?
Diagnosis is based on clinical history, physical exam, and imaging:
- History: Classic post‑prandial RUQ pain that resolves within hours.
- Physical exam: Mild tenderness in RUQ, but no peritoneal signs. Murphy’s sign is usually negative.
- Ultrasound (first‑line): Shows gallstones, no gallbladder wall thickening, no pericholecystic fluid.
- Liver function tests: Normal (unless a stone has migrated into the common bile duct).
- Complete blood count: Normal white cell count (if elevated, suspect cholecystitis).
Treatment of biliary colic – pain relief and definitive therapy
Acute pain relief:
- NSAIDs (ibuprofen, diclofenac): First‑line for biliary colic – they reduce inflammation and pain.
- Paracetamol (acetaminophen): Weaker but safe.
- Antispasmodics (hyoscine butylbromide – Buscopan): May help by relaxing smooth muscle.
- Avoid opioids if possible – they can cause sphincter of Oddi spasm and worsen pain.
Definitive treatment (prevent recurrence):
- Laparoscopic cholecystectomy (gallbladder removal): Gold standard for recurrent biliary colic. Ideally performed within 2‑4 weeks after diagnosis.
- Observation (low‑fat diet): For patients who cannot undergo surgery (high risk) or refuse surgery. However, recurrence is common (50% within 5 years).
- Ursodeoxycholic acid (UDCA): May dissolve small cholesterol stones but is not effective for symptom control.
Interactive FAQ – Biliary colic
Biliary colic itself is not dangerous, but it indicates you have gallstones that can cause complications (cholecystitis, pancreatitis, cholangitis) in the future. Recurrent colic is a reason to consider cholecystectomy.
Yes – biliary colic can cause epigastric pain, nausea, and sweating, similar to a heart attack. However, heart attack pain is central chest, may radiate to left arm or jaw, and is often triggered by exertion, not fatty meals. If uncertain, seek emergency care.
Fatty meals stimulate the gallbladder to contract and release bile. If a stone blocks the cystic duct during contraction, pressure builds and causes pain. Low‑fat meals cause less gallbladder contraction.
Take ibuprofen or diclofenac (if no contraindications). Apply a warm compress to the right upper quadrant. Avoid eating until pain subsides. If pain persists >6 hours or you develop fever, seek medical attention.
No – biliary colic resolves spontaneously. Surgery is elective, usually scheduled within 2‑4 weeks. However, if pain persists or you develop fever, you may have acute cholecystitis, which may require urgent surgery.
Low‑fat meals reduce the frequency of attacks, but they do not prevent stones or guarantee freedom from pain. Cholecystectomy is the only definitive cure.
It can occur at any time, but often after the evening meal (the largest meal of the day). Nighttime attacks are common.
Yes – referred pain to the right shoulder or shoulder blade is classic. This occurs because the gallbladder and diaphragm share phrenic nerve innervation (C3‑C5).
Immediately. Once the gallbladder is removed, the source of pain is gone. However, some patients may have post‑cholecystectomy syndrome (unrelated to biliary colic).
