Mild itching during pregnancy is common and usually harmless. But intense itching — especially on your palms and soles, and worse at night — can be a sign of intrahepatic cholestasis of pregnancy (ICP), a liver condition that needs attention. Don't dismiss it as "just pregnancy itch" without mentioning it to your doctor.
What is ICP?
Intrahepatic cholestasis of pregnancy is a liver condition that usually develops in the third trimester, where bile acids build up in the mother's blood instead of flowing normally through the liver and out of the body. The buildup of bile acids is what causes the itching.
The symptoms to watch for
- Severe itching, especially on the palms of the hands and soles of the feet
- Usually no visible rash — the skin can look completely normal despite intense itching
- Sometimes dark urine, pale stools, or mild jaundice (yellowing of the skin or eyes)
- Itching that tends to be worse at night
Why it matters
ICP can increase the risk of preterm birth, fetal distress, and, in severe cases, stillbirth. This is why it's treated as a genuine warning sign rather than a cosmetic discomfort. The reassuring part: with timely diagnosis, medication, and close monitoring, these risks can be significantly reduced.
If you're pregnant and experiencing severe itching — especially on your palms and soles, worse at night — don't ignore it. Consult your obstetrician.
How it's diagnosed
Your doctor will typically order:
- Serum bile acid levels — the key diagnostic test
- Liver function tests (LFTs) — to check how your liver is handling the bile acid buildup
These are simple blood tests, and a diagnosis is usually confirmed once bile acid levels come back elevated.
What treatment looks like
- Medicines to reduce bile acid levels — prescribed by your doctor once ICP is confirmed
- Regular fetal monitoring — to track the baby's wellbeing through the rest of the pregnancy
- Planned delivery, often around 36-37 weeks depending on severity, rather than waiting for labour to start on its own
The exact timing and treatment plan depends on how high your bile acid levels are and how your pregnancy is otherwise progressing, so this is a conversation to have directly with your doctor rather than a fixed rule.
Does it go away, and can it come back?
ICP usually resolves on its own after delivery. However, it can recur in future pregnancies, so if you've had it once, mention this history early in any subsequent pregnancy so your doctor can monitor for it from the start.
How this is different from ordinary pregnancy itching
Our guide on early pregnancy symptoms covers mild, generalised itching — including itchy palms and feet — as a usually-harmless hormonal change. The difference with ICP is intensity, location, and timing: itching that is severe, concentrated on the palms and soles, and noticeably worse at night, especially in the third trimester, is what should prompt a call to your doctor rather than being written off.
Frequently asked
How is ICP different from normal pregnancy itching?
Normal pregnancy itching tends to be mild, spread across the body (especially the belly as skin stretches), and doesn't come with a specific pattern. ICP itching is typically intense, concentrated on the palms and soles, worse at night, and not accompanied by a rash.
At what point in pregnancy does ICP usually develop?
Most commonly in the third trimester, though it can occasionally start earlier.
Will I need an early delivery if I'm diagnosed with ICP?
Often, yes — delivery is typically planned around 36-37 weeks depending on how severe your bile acid levels are, rather than waiting for spontaneous labour. Your doctor will decide the exact timing based on your bile acid levels and fetal monitoring.
Can ICP harm the baby if treated?
With timely diagnosis, bile-acid-lowering medication, close fetal monitoring, and planned delivery, the risks associated with ICP can be significantly reduced. Untreated or late-diagnosed ICP carries higher risk, which is why reporting severe itching promptly matters.
If I had ICP in a previous pregnancy, will I get it again?
It can recur. Tell your doctor about a prior ICP diagnosis as soon as you confirm a new pregnancy so monitoring can start early.
