Understanding Hives During Pregnancy: Causes, Symptoms, and Treatment

Pregnancy is a beautiful journey marked by numerous bodily changes and experiences, but it can also bring its share of discomforts. One common skin condition many expecting mothers encounter is hives, also known as urticaria. This article delves into the causes, symptoms, treatment options, and concerns regarding hives during pregnancy, ensuring you are informed and prepared.

What Are Hives?

Hives are itchy, elevated welts on the skin, typically red or skin-colored, that can appear anywhere on the body. These welts may vary in size and can change location over a short period. According to the Office on Women’s Health, approximately 20% of pregnant women experience itchiness during their pregnancy — a condition that can sometimes lead to hives.

Is It Normal to Have an Outbreak of Hives During Pregnancy?

Research does not indicate a heightened risk of developing hives during pregnancy as compared to non-pregnant times. While hormonal changes and skin sensitivities can lead to outbreaks, the general risk remains the same. A useful tip to keep in mind: if you press the center of a red hive, it will blanch, turning temporarily white — a phenomenon known as blanching.

Causes of Hives During Pregnancy

As your body changes throughout pregnancy, your immune system may misinterpret these changes as foreign invaders, leading to the release of histamine into your bloodstream — a key factor behind hives development. Potential triggers during this period may include:

• Animal dander
• Medicines
• Chemicals
• Insect bites
• Pollen
• Food allergies (e.g., fish, shellfish, eggs, nuts, milk)
• Hormonal fluctuations
• Environmental factors (e.g., exposure to sun, cold, or water)
• Emotional stress
• Sweating and physical activity
• Infections

A specific type of hives known as pruritic urticarial papules and plaques of pregnancy (PUPPP) often surfaces in the third trimester. This condition typically manifests in the stretch marks of the abdomen and may spread to the chest and legs.

Symptoms of Hives During Pregnancy

Hives can manifest as small clusters of welts on various body parts, including the arms, legs, and back. Symptoms include:

• Raised red welts on the skin
• Localized swelling (angioedema)
• Intense itching
• Dry skin
• Severe pain in some cases

Cami, a pregnant blogger, shared her experience: “I have now broken out in hives all over my body. Red, weltish, itchy, itchy, itchy hives! Constant itch… then constant pain… then constant itch all over.”

While most cases of hives do not require specific testing, your doctor may perform a blood test or skin biopsy if the cause of the allergy needs to be identified.

Treatment for Hives During Pregnancy

If you experience hives, consulting a healthcare professional is crucial. Self-medicating with over-the-counter drugs is not advisable. For the treatment of hives, your doctor may recommend the use of over-the-counter antihistamines, such as:

• Benadryl
• Allegra
• Claritin
• Chlor-Trimeton
• Zyrtec

In cases of severe rashes like PUPPP, they may prescribe oral medications or anti-itch creams. In more severe instances, a low dose of corticosteroids or topical creams with corticosteroids might be suggested, though these should only be used under medical advice.

Natural Remedies for Hives During Pregnancy

Some expecting mothers prefer natural remedies to alleviate symptoms. Here are several effective options:

• Oatmeal baths: Known for their anti-inflammatory properties, oatmeal can help relieve itching.
• Aloe vera: Apply fresh aloe vera gel to the affected area for its soothing effects.
• Lukewarm baths: Avoid hot baths as they can worsen the itching. Opt for cooler water instead.
• Green tea: Drinking green tea might help eliminate toxins and allergens, providing relief from itching.
• Milk compress: Dab a clean cloth in milk and apply it to the affected areas to ease inflammation.
• Baking soda: Adding baking soda to a bath or creating a paste can help relieve itching.
• Witch hazel: This natural remedy can be applied directly to the skin to reduce irritation.
• Peppermint oil: When diluted with a carrier oil, peppermint can provide a cooling sensation and ease discomfort.

Tips to Prevent Hives During Pregnancy

If you are susceptible to hives, implementing these preventative measures may reduce your risk:

• Choose loose-fitting cotton clothing over tight, synthetic fabrics.
• Avoid hot baths and showers which may aggravate your skin.
• Minimize skin pressure and refrain from scratching.
• Practice stress-reduction techniques to maintain emotional well-being.
• Use unscented cosmetics and avoid harsh detergents or fabric softeners.

Do Hives Go Away After Pregnancy?

Typically, pregnancy-related hives resolve within a week of delivery. However, in some instances, they may persist for up to six weeks post-delivery, a condition referred to as postpartum hives.

Are Hives Dangerous During Pregnancy?

Generally, hives during pregnancy are harmless and often resolve without intervention. However, severe allergic reactions can occur, manifesting as swelling around the eyes, lips, and throat, leading to breathing difficulties. This situation constitutes a medical emergency, demanding immediate hospital attention.

Common Questions About Hives in Pregnancy

1. Do hives predict the baby’s gender?
   There is a myth that rash and itchy skin during pregnancy indicates a baby girl, but there is no scientific evidence supporting this.

2. Can hives develop early in pregnancy?
   Women prone to hives might experience outbreaks early in their pregnancy.

3. Do hives affect the baby?
   Hives during pregnancy do not harm fetal health, and no risks to the baby in the womb or post-birth have been reported.

4. Are hives linked to miscarriage?
   There is no evidence linking hives to miscarriage.

5. Why do hives worsen at night?
   Allergic reactions, including hives, may intensify at night due to increased plasma histamine levels.

Conclusion

Hives, characterized by itchy raised bumps on the skin, can be an uncomfortable experience for pregnant women. While they are generally not harmful and often resolve on their own, being informed about their causes, symptoms, and treatment options is essential. If hives develop, it’s crucial to consult a healthcare professional rather than relying on self-medication. By following preventative measures and utilizing home remedies, many women can find relief, allowing them to enjoy this unique chapter of their lives with greater comfort.
