Written by Swathi E, Certified Skin Care Coach

Over 90% of women see changes in their skin in one form or the other during pregnancy (1). One of the most common changes they notice during this time is pregnancy skin rashes. These rashes can occur anywhere on the body and may fade away after childbirth. However, some of them can cause serious health issues. Therefore, you may need to seek immediate medical attention.

Read on to learn all about pregnancy skin rashes, their types, causes, and treatment options available.

What Causes Rash During Pregnancy?

Skin rashes during pregnancy could be due to hormonal changes, changes in pre-existing conditions, or the development of new pregnancy-specific dermatoses (defects or lesions) (1).

Dr. Daniel Grabell, a board-eligible dermatologist, says, “Rashes in pregnancy occur for a number of reasons, including changes in hormones as well as the immune system adapting to having a baby.”

These pregnancy rashes can vary in severity and duration. They may appear anywhere on the body and look different depending on the cause and type.

“Most rashes are not severe, but a few can raise concerns requiring medical attention to keep both the baby and mother safe,” says Dr. Grabell.

To treat a pregnancy rash, you need to know what type of pregnancy rash you have. Keep reading to learn about the different types of pregnancy rashes.

Types Of Pregnancy Skin Rashes

  • Heat Rash

During pregnancy, increased blood supply to the skin can lead to increased sweating and heat rashes (2). A heat rash may cause itching, red spots, and swelling. Staying cool and avoiding activities that cause sweating can help control heat rashes.

Heat rashes do not require any specific treatment as they fade away on their own in a few days. However, you may use antihistamines or calamine lotion to soothe the skin.

  • Hives

Hives are itchy, raised bumps caused by a reaction to food, medicine, or other irritants. Hormonal changes during pregnancy may also lead to hives (3). They can burn or sting. Usually, hives appear suddenly and fade away within a few days or six weeks.

To treat hives, you may take antihistamines or medications that soothe inflammation. However, if the hives don’t heal even after six weeks, or if they swell or make breathing difficult, you should consult a doctor at the earliest.

  • PUPPP Rash

Pruritic urticarial papules and plaques of pregnancy, also known as PUPPP, occur in 1 out of 130 to 300 pregnancies. A PUPPP rash usually causes itchy bumps on the stretch marks on the abdomen. It occurs in the third trimester of pregnancy and goes away after childbirth. It is also more common in first pregnancies and women pregnant with twins or triplets (4), (5).

According to Dr. Grabell, the exact cause is unknown. But he says, “It is believed to be caused by stretching of the connective tissue in the skin exposing proteins to the immune system.”

You may treat a PUPP rash with antihistamines or topical steroids.

  • Pemphigoid Gestationis

This is a rare autoimmune disease that affects 1 in 50,000 pregnant women. This condition causes an itchy, hive-like rash around the abdomen and spreads to other parts of the body. It may also turn into blistering lesions. It occurs around the second or third trimester of pregnancy and fades away after childbirth. It may also flare up at delivery (1).

Though there has been no proof of any fetal risks, newborns were born with skin lesions in some cases (1).

You may treat the condition with steroids, lotions, or antihistamines.

  • ICP

Intrahepatic cholestasis of pregnancy is a serious liver condition that causes itching on the palms of the hands and soles of the feet. It may also spread to other parts of the body and may not always start as a rash. Usually, it occurs in the third trimester and may cause jaundice (6).

It is important to seek medical attention at the earliest. Dr. Grabell says, “The build-up of bile acid causes ICP in the bloodstream. This is a pregnancy emergency as high levels of bile acid are harmful to the fetus. Care is needed right away to lower the bile level.”

  • Atopic Eruption Of Pregnancy

This is the most common pregnancy-related skin disorder (6). There are three skin conditions under this category:

    • Atopic Eczema: Symptoms include a dry and itchy rash during pregnancy’s first and second trimesters (6).
    • Prurigo Of Pregnancy: It is a rash with small bumps filled with fluids. It may occur during all trimesters (6).
    • Pruritic Folliculitis Of Pregnancy: Skin lesions resembling pimples or acne occur in the fourth to the ninth month of pregnancy (6).

These rashes often disappear after delivery and do not cause any risk to you or your child. You may treat them with topical medications, emollients, or oral antihistamines.

  • Impetigo Herpetiformis

This rash appears as lesions in the skin folds. It occurs during the last trimester and is similar to pustular psoriasis, which causes severe skin inflammation. The affected person may also experience fever, diarrhea, dehydration, seizures, and rapid heartbeat. Though this condition heals after childbirth, there has been a rare case of stillbirth associated with it (7).

You may consult a doctor to reduce the risk and manage the condition.

Since most of these pregnancy skin rashes are not a cause for concern, you may use several home remedies to soothe your skin and heal the inflammation. Read on to learn more.

Home Remedies For Pregnancy Skin Rashes

You may try the following remedies to soothe your skin affected by eczema, hives, or heat rash:

  • Always use cold or lukewarm water for washing your hands, face, and bathing.
  • Use a gentle, unscented cleanser to keep your skin clean.
  • Moisturize your skin with emollients soon after taking a shower.
  • Always wear loose clothing made of cotton or any natural fibers.
  • Drink adequate amounts of water and avoid caffeinated beverages.
  • Take colloidal oatmeal baths and use calamine lotion to soothe itching.
  • Avoid scratching the skin.

These simple home remedies may help you heal the inflammation and soothe your skin. But, first, you should know when to consult a doctor. Read on to know when to consult a doctor and the treatment options available.

When Should You Consult A Doctor?

Most pregnancy skin rashes respond well to home remedies. But, it is always good to consult a doctor to identify the cause and confirm if you need medical treatment.

You may seek immediate medical attention if:

  • You experience severe itching without a rash.
  • A rash appears and spreads quickly.
  • You notice breathing difficulty and swelling along with the rash.
  • The rash looks infected.
  • You notice yellowing of the skin, pain, or fever.

Diagnosis And Treatment

For diagnosis, your doctor may ask about your symptoms, when they started, and how they spread. Then, they may prescribe additional tests based on the type of rash and the complications. Blood tests, allergy tests, and skin biopsies are all different diagnosis methods to determine the treatment needed for the rash.

According to Dr. Grabell, “Treatment varies by the type of rash but ranges from good moisturizing creams to topical steroids.” Your doctor may prescribe systemic steroids, antihistamines, or topical steroids based on the rash and severity.

Most women face skin rashes during pregnancy, among other skin and health-related issues. Studies suggest that hormonal changes or changes in pre-existing conditions may cause pregnancy skin rashes. Once you identify whether you have hives, PUPPP, or heat rash, you can treat them accordingly. As most pregnancy skin rashes are not severe, you can use a gentle cleanser to soothe your skin and drink lots of water to provide relief. However, if the rash spreads quickly and is accompanied by itching and fever, consult your doctor immediately.
