Itching during pregnancy is common and usually caused by hormonal shifts and your skin stretching as your baby grows. Most of the time it’s harmless, but intense or persistent itching, especially on your palms and soles, can signal a liver condition that needs prompt attention. Understanding what’s behind the itch helps you figure out which category yours falls into.
Hormonal Changes and Stretching Skin
The most common reasons for pregnancy itching are also the most benign. Rising levels of estrogen and other hormones change the way your skin retains moisture and responds to irritation. Meanwhile, your blood volume increases by nearly 50% over the course of pregnancy, which can make skin feel warm, flushed, and itchy, particularly on the belly, breasts, and thighs where stretching is most dramatic.
This type of itching tends to come and go, stays mild to moderate, and doesn’t produce a rash. Cool showers, fragrance-free moisturizers, and loose cotton clothing are usually enough to keep it manageable. If your skin feels dry or tight rather than inflamed, this is likely what you’re dealing with.
PUPPP Rash
PUPPP (pruritic urticarial papules and plaques of pregnancy) is the most common pregnancy-specific rash, showing up in about 1 in 160 pregnancies. It typically appears around week 35, starting as itchy, red, hive-like bumps in the stretch marks on your belly, then sometimes spreading to your thighs and arms. It looks alarming but poses no risk to your baby.
PUPPP is more common in first pregnancies and in people carrying multiples. The rash usually resolves on its own within a few weeks, often clearing up shortly after delivery. In the meantime, calamine lotion, oatmeal-based creams, and over-the-counter hydrocortisone cream (up to 1% strength) are all considered safe during pregnancy and can take the edge off. If the itching is severe enough to interfere with sleep, your provider may prescribe a stronger topical treatment or an oral antihistamine.
Prurigo of Pregnancy
Prurigo of pregnancy is actually the most common skin condition of pregnancy overall, occurring in about 1 in 300 pregnancies. It shows up as small, itchy, eczema-like bumps that can appear on your arms, legs, or torso. The bumps may be scattered or concentrated in areas where eczema typically flares: the inner elbows, backs of the knees, neck, and face.
Prurigo can start in any trimester and sometimes lingers for weeks after delivery. It’s benign and doesn’t affect the baby. Treatment is similar to managing eczema outside of pregnancy: regular moisturizing, avoiding hot water and harsh soaps, and using topical anti-itch creams. If you had eczema before pregnancy, you’re more likely to develop this.
Cholestasis of Pregnancy: The One to Watch For
Intrahepatic cholestasis of pregnancy (ICP) is a liver condition that causes intense itching, usually starting on the palms of your hands and the soles of your feet before spreading. It typically develops in the third trimester, and the itching is often worse at night. Unlike the other causes on this list, ICP carries real risks for your baby and requires medical management.
What happens in ICP is that bile acids, which your liver normally processes and sends to your digestive tract, build up in your bloodstream instead. Those excess bile acids can cross the placenta and reach your baby, potentially causing complications including preterm delivery and, in severe cases, stillbirth. The risk rises significantly when bile acid levels in your blood climb above a certain threshold, so your provider will monitor those levels with a simple blood test.
There are a few details that set ICP apart from ordinary pregnancy itching:
- Location: The itch starts on your palms and soles, which is unusual for other causes.
- Intensity: It’s often described as relentless, not just annoying. Many people say it feels like it’s coming from deep under the skin.
- No visible rash: Unlike PUPPP or prurigo, ICP doesn’t produce bumps or hives (though you may scratch enough to create marks).
- Other symptoms: Some people notice dark urine, pale or greasy stools, nausea, or yellowing of the skin and eyes.
If you’re diagnosed with ICP, treatment focuses on lowering your bile acid levels and planning an earlier delivery to reduce risk to the baby. Your provider will likely prescribe a medication that helps your liver process bile acids more efficiently and will monitor your baby more closely for the rest of the pregnancy. Many people with ICP deliver between 36 and 37 weeks, depending on bile acid levels and how the baby is doing.
Pemphigoid Gestationis
This is rare, affecting roughly 1 in 50,000 pregnancies, but worth knowing about. It starts as intense itching around the belly button, usually in the second or third trimester. Over the following weeks, red patches and hive-like bumps spread across the abdomen and limbs, and fluid-filled blisters may develop. It’s an autoimmune condition where your body’s immune system mistakenly targets a protein in your skin. Treatment typically involves prescription steroid creams or, in more severe cases, oral steroids. Your provider will monitor the baby more closely since the condition can occasionally cause preterm delivery or low birth weight.
Relief That’s Safe During Pregnancy
For everyday itching that isn’t linked to a specific condition, several over-the-counter options are considered safe. Calamine lotion is a classic standby that cools and soothes irritated skin. Colloidal oatmeal creams (like Aveeno’s anti-itch line) help restore the skin barrier and calm inflammation without steroids. Hydrocortisone cream at 1% strength can be used for short periods on small areas. Diphenhydramine-based creams and gels (the active ingredient in Benadryl cream) offer topical relief as well.
A few practical habits make a difference too. Lukewarm showers instead of hot ones help preserve your skin’s natural oils. Applying moisturizer immediately after bathing, while your skin is still slightly damp, locks in hydration. Wearing breathable fabrics and keeping your bedroom cool at night can reduce the nighttime itch flare that many pregnant people experience. If you’re using laundry detergent with fragrance, switching to a free-and-clear version sometimes helps more than you’d expect.
When Itching Needs Immediate Attention
Contact your provider right away if your itching is constant, worsening, or concentrated on your palms and soles. The same goes if you notice yellowing of your skin or the whites of your eyes, unusually pale stools, dark urine, or nausea alongside the itching. These can be signs of cholestasis, and a blood test can confirm or rule it out quickly. Early detection makes a significant difference in outcomes, so don’t wait for your next scheduled appointment if the itch feels different from normal dry-skin discomfort.
