Prurigo of Pregnancy: Symptoms, Causes, Treatment

What are the symptoms of prurigo of pregnancy?

Prurigo of pregnancy, also known as pruritic folliculitis of pregnancy, is a condition that typically occurs during the second and third trimesters. The symptoms include:

• Intense Itching: The primary symptom is intense itching, which can be widespread or localized to certain areas of the body. The itching can be persistent and uncomfortable.
• Papules and Nodules: Small, red, itchy bumps (papules) or larger nodules may develop on the skin. These lesions often appear on the arms, legs, and trunk but can occur anywhere on the body.
• Scratching and Secondary Lesions: Due to the intense itching, scratching can lead to excoriations (skin sores) and secondary infections.
• Skin Discoloration: The affected areas may become darker or lighter than the surrounding skin due to repeated scratching and healing.
• Onset During Pregnancy: Symptoms usually begin during the second or third trimester of pregnancy and can persist until delivery. In some cases, the condition may last for a few weeks postpartum.

Prurigo of pregnancy is not harmful to the mother or baby but can significantly impact the mother’s comfort and quality of life. If you suspect you have this condition, it’s important to consult with a healthcare provider for proper diagnosis and management.

What are the causes of prurigo of pregnancy?

The exact cause of prurigo of pregnancy is not well understood, but several factors are believed to contribute to its development. These include:

• Hormonal Changes: The significant hormonal fluctuations that occur during pregnancy, particularly the increase in estrogen and progesterone levels, may play a role in triggering prurigo of pregnancy.
• Immune System Alterations: Pregnancy induces changes in the immune system, which may lead to the development of skin conditions such as prurigo. The immune system’s altered response can result in increased sensitivity and inflammation in the skin.
• Genetic Predisposition: Some women may have a genetic predisposition to developing prurigo of pregnancy. If a woman has a family history of similar skin conditions, she may be more likely to experience prurigo during pregnancy.
• Atopic Dermatitis History: Women with a history of atopic dermatitis (eczema) or other allergic skin conditions may be more prone to developing prurigo of pregnancy.
• Environmental Factors: External factors, such as stress, changes in weather, or exposure to certain allergens or irritants, might exacerbate the condition or trigger its onset.

Prurigo of pregnancy is a benign condition, and while it can be uncomfortable and bothersome, it does not pose any risk to the mother or the baby. However, it is important to consult with a healthcare provider to ensure proper diagnosis and management.

What is the treatment for prurigo of pregnancy?

The treatment for prurigo of pregnancy focuses on relieving itching and managing symptoms to improve comfort. Treatment options include:

Topical corticosteroids can help reduce inflammation and itching when applied directly to the affected areas. Mild to moderate corticosteroids are typically recommended.

Moisturizers and emollients keep the skin hydrated and reduce dryness and itching. These should be applied regularly to maintain skin moisture.

Antihistamines may be prescribed to help alleviate itching. Non-sedating antihistamines are preferred during pregnancy.

Topical calcineurin inhibitors, such as tacrolimus or pimecrolimus, may be used as an alternative to corticosteroids, especially for sensitive skin areas.

Soothing baths, such as oatmeal baths or using gentle, fragrance-free bath products, can help soothe the skin and reduce itching.

Keeping cool and avoiding heat and sweat can prevent worsening of itching. Wearing loose, breathable clothing can also help.

Avoiding triggers like harsh soaps, perfumes, and irritants can reduce skin irritation. Maintaining gentle skin care routines is important.

In some cases, a doctor may recommend low-dose oral corticosteroids if the symptoms are severe and not controlled by other treatments. This is done with caution and under medical supervision.

The symptoms of prurigo of pregnancy typically resolve after delivery, but if the condition persists, further evaluation and treatment may be necessary. Always consult with a healthcare provider before starting any treatment to ensure safety for both the mother and the baby.
