Itchy Palms in Pregnancy: Why Cholestasis Must Be Ruled Out

Itchy skin is common in pregnancy. For many women, mild itching on the belly, breasts or thighs can simply be due to growing skin and rising hormones. However, when the palms and soles itch intensely, a more serious condition—intrahepatic cholestasis of pregnancy (ICP)—must be considered. ICP can affect the health of both mother and baby, so early recognition and testing are essential.

Understanding Itchy Palms in Pregnancy

During pregnancy, your body makes extra hormones (especially estrogen) that can slow down bile flow in the liver. Bile acids build up, spill into the bloodstream and settle in the skin, causing itching. While mild itching on the belly is often harmless, intense itching on the palms and soles should prompt an evaluation for ICP.

Common, benign causes of itching in pregnancy:

• Hormonal changes: Elevated estrogen levels
• Stretching skin: Rapid weight gain or growing belly
• Dry skin: Especially in colder months or low-humidity environments
• Atopic eruption: A flare of eczema/psoriasis

Warning sign:

• Itching localized to the palms and soles, without a rash, that intensifies at night.

What Is Intrahepatic Cholestasis of Pregnancy (ICP)?

ICP is a liver disorder unique to pregnancy. It usually appears in the late second or third trimester and affects about 0.5–2% of pregnancies in Western countries. ICP is characterized by:

• Pruritus (itching): Most often on palms and soles, no visible rash
• Elevated liver enzymes: Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)
• Increased serum bile acids: A key lab test for diagnosis

Why ICP Matters

If untreated, ICP can increase risks for:

• Preterm birth
• Fetal distress
• Meconium-stained amniotic fluid
• Stillbirth (particularly when bile acids exceed 100 µmol/L)

Early detection and management help reduce these risks.

Recognizing the Symptoms

Symptoms of ICP can vary, but the hallmark is intense itching without a rash, most noticeable on:

• Palms of hands
• Soles of feet

Other possible signs:

• Dark urine
• Pale stools
• Jaundice (yellowing of skin or eyes), though this is less common

Note: Sleep disturbance from itching can add to fatigue and stress, so it’s important to address symptoms early.

Diagnosing ICP

If you report itchy palms in pregnancy, your provider will likely recommend:

1. Blood tests

   • Serum total bile acids (primary test)
   • Liver function tests (ALT, AST, bilirubin)

2. Additional work-up

   • Viral hepatitis screen (to exclude other liver conditions)
   • Review of medications and family history

A bile acid level above 10 µmol/L generally confirms ICP. Levels above 40 µmol/L are associated with higher fetal risk.

Managing ICP

Once diagnosed, management focuses on:

• Relieving itching
• Monitoring maternal liver health
• Ensuring fetal well-being

Medical Treatments

• Ursodeoxycholic acid (UDCA)
  • First-line therapy to lower bile acids and improve liver tests
  • Helps reduce itching in many patients
• Symptomatic relief
  • Chill packs or cool showers
  • Moisturizers (fragrance-free)
  • Antihistamines (cautiously, under doctor supervision)

Fetal Monitoring

• Non-stress tests (NSTs)
• Biophysical profiles
• Ultrasounds for growth and amniotic fluid

Frequency depends on bile acid levels and gestational age.

Timing of Delivery

• Mild ICP (bile acids 10–40 µmol/L): Consider delivery at 37–38 weeks
• Severe ICP (>40 µmol/L): Often recommend delivery by 36–37 weeks to reduce stillbirth risk

Your obstetrician will tailor the plan based on:

• Severity of itching
• Bile acid levels
• Overall pregnancy health

Other Possible Causes of Itchy Palms

While ICP is crucial to exclude, other conditions can cause palm and sole itching:

• Allergic contact dermatitis: Reaction to lotions, gloves or chemicals
• Atopic eczema: Worsening of preexisting eczema
• Psoriasis: May flare in pregnancy
• Palmoplantar pustulosis: Rare, may cause pustules and scaling

Your provider may perform a skin exam or patch testing if ICP is ruled out.

Supporting You Through Investigation

It’s natural to worry when symptoms arise. To help decide if you need prompt medical attention, consider taking a quick self-assessment. Try a

When to Call Your Doctor

Contact your healthcare provider if you experience:

• Persistent itching of palms and/or soles, especially at night
• Any jaundice (yellowing of eyes or skin)
• Dark urine or pale stools
• Signs of preterm labor (cramping, contractions)

ICP can escalate rapidly. Early testing and management are key to keeping you and your baby safe.

Key Takeaways

• Itchy palms in pregnancy are not always harmless and require evaluation.
• Intrahepatic cholestasis of pregnancy is a liver disorder marked by elevated bile acids and intense itching of hands/feet.
• Diagnosis hinges on serum bile acid levels and liver function tests.
• Treatment with ursodeoxycholic acid, close monitoring, and timely delivery reduce risks.
• Always rule out serious causes before assuming itching is “just normal.”

Speak to a doctor about any concerning symptoms to rule out life-threatening conditions. Early detection of ICP can make a big difference for you and your baby.
