A Raised Bilirubin with a Raised ALP and GGT
Bile is not getting out. ALP and GGT rise when the ducts are irritated or obstructed, and bilirubin rises once the blockage is complete enough that it backs up into the blood. That sequence makes this a mechanical problem until an ultrasound says otherwise, and two versions of it need seeing today rather than next week.
The pattern on your report
- Bilirubin High · moderate Key
- ALP High · marked Key
- GGT High · marked Key
- ALT High-normal Key
Printed as: ALT in U/LALP in U/LGGT in U/LBilirubin in umol/Lor mg/dL— Around seventeen times apart, so 51 umol/L is about 3.0 mg/dL. Reports may split it into direct and indirect, and here the direct fraction is the raised one.
Why the numbers look like this
Bilirubin leaves the liver conjugated, in bile, through a duct system that narrows into a single channel before joining the bowel. Anything narrowing that channel raises the pressure behind it. The cells lining the ducts respond by producing more ALP and GGT, which is why those two move first.
Bilirubin needs more than irritation. It needs the flow to be genuinely impeded, so it lags behind, and its appearance marks a later stage. The bilirubin that accumulates is the conjugated kind, already processed by the liver, which is why it dissolves in water and turns the urine dark while the stools lose their color.
That pigment story is diagnostic on its own. Dark urine with pale stools means conjugated bilirubin is being diverted to the kidney because it cannot reach the bowel, and it separates this pattern from the unconjugated kind that never reaches the urine at all.
Not being flagged is not the same as normal
Jaundice becomes visible in the whites of the eyes only once bilirubin is two or three times its printed ceiling, so a bilirubin can be clearly abnormal on paper while nothing is visible in the mirror. The pattern is defined by its shape, not its height: ALP and GGT disproportionately raised compared with ALT. A normal-looking bilirubin does not exclude obstruction either, because an incomplete blockage can leave it in range while the ducts are already dilated.
What else on the report can hide this
Fever is the first thing to establish, because fever with this pattern and pain means infected bile behind an obstruction. That is a surgical emergency treated by draining the duct, which is why urgency comes before any differential here.
Pain is the next question, and its absence is not reassuring. Painless jaundice with weight loss is the classic presentation of a tumor at the head of the pancreas, and it is the version that gets watched when it needs investigating fast.
Ultrasound answers the mechanical question first: dilated ducts mean something is obstructing them. If the ducts are normal, the problem lies inside the liver, and antimitochondrial antibodies, a drug history and a viral screen become the priorities instead.
What usually causes it
Listed from most to least common — not from most to least serious.
- Very common
Gallstone obstructing the bile duct
Often with episodic right upper abdominal pain after eating. A stone can pass on its own, so the numbers fluctuate, and a settling episode does not mean the stone has gone.
- Common
Ascending cholangitis
Infected bile behind an obstruction. Fever with right upper abdominal pain and jaundice is the recognized combination, and it needs the duct drained. This is the emergency on the list.
- Common
Cancer at the head of the pancreas or of the bile duct
Classically painless jaundice with weight loss and a steadily rising bilirubin. Absence of pain is a feature, not reassurance.
- Common
Drug-induced cholestasis
Co-amoxiclav is the archetype and can begin weeks after the course ended. Also flucloxacillin, anabolic steroids and some antipsychotics. Recovery is slow, over months.
- Uncommon
Alcoholic hepatitis
Jaundice with a tender enlarged liver in someone drinking heavily, usually with an AST-dominant transaminase pattern alongside.
- Uncommon
Primary biliary cholangitis or sclerosing cholangitis
Usually reach this stage after years of a raised ALP and GGT with a normal bilirubin. Antimitochondrial antibodies, or MRCP showing duct changes.
- Uncommon
Liver metastases or an infiltrative process
An enlarged liver, a known primary cancer, or a raised calcium. Imaging finds it.
- Uncommon
Pregnancy-related cholestasis — in the second half of pregnancy
Intense itching, often of the palms and soles and worse at night, with raised bile acids. It carries risk to the pregnancy and is managed by the obstetric team.
What is usually checked next
- Ultrasound of the liver and bile ducts, urgently Dilated ducts mean obstruction and change everything that follows. Normal ducts redirect the investigation inside the liver.
- Temperature, pulse and blood pressure, with a full blood count and CRP Identifies cholangitis, which is time-critical and treated by drainage rather than by antibiotics alone.
- MRCP or endoscopic ultrasound Images the ducts and the pancreatic head in detail when ultrasound is unrevealing or a tumor is suspected.
- A full medication history including anything stopped in the past three months Drug cholestasis often starts after the drug has been finished, so a current list misses it.
- Bile acids, in pregnancy Confirms obstetric cholestasis, which is managed differently and affects decisions about delivery.
When to seek care sooner
- Emergency Fever or shivering with pain under the right ribs
- Emergency Confusion or drowsiness with jaundice
- Emergency Low blood pressure, a fast pulse, or feeling faint
- Same day Jaundice with no pain, alongside unintentional weight loss
- Same day Pale stools with dark urine
- Same day Intense itching in pregnancy, particularly of the palms and soles
- Same day Bruising easily, or a rising INR
Questions worth bringing to your appointment
- Has an ultrasound been arranged, and how soon?
- Are my bile ducts dilated?
- Have I had any fever, and does that change how urgently this is handled?
- Could a medicine from the past few months be responsible?
- If the ultrasound is normal, what is the next imaging step?
