Pruritic Urticarial Papules and Plaques of Pregnancy
This is the most common form of rash during pregnancy. About 1 in 250 pregnant women are affected by it.
It involves the development of an itchy red rash in the last three months of pregnancy, which can spread over almost the entire body. The lesions resemble hives (urticaria) and vary from small bumps to large patches. In severe cases, blisters can even form in these patches.
The cause of PUPPP is unknown. It is likely an autoimmune process where the mother's skin reacts to certain proteins from the baby or the placenta.
PUPPP is not dangerous for the baby.
Symptoms
- Red, raised bumps and larger inflamed patches on the skin.
- Intense itching, primarily on the abdomen, but also on the legs, arms, and buttocks.
- The rash may spread but rarely reaches the face, palms, or soles.
Causes
The exact cause of PUPPP is unknown and it is not considered hereditary. Theories suggest that rapid abdominal skin stretching during pregnancy may trigger natural defensive reactions of the skin, leading to the rash.
Diagnosis
Diagnosis is mainly based on the appearance of the rash and symptoms, possibly supplemented by a skin biopsy to rule out other conditions.
Treatment
- Corticosteroid creams for itching and inflammation.
- Antihistamines to relieve itching.
- Moisturizing creams to keep the skin hydrated.
- In severe cases, oral steroids may be prescribed.
Self-care Tips
- Wear loose cotton clothing.
- Use gentle, hypoallergenic soap.
- Take lukewarm baths with oatmeal or baking soda.
- Apply a cold compress to itchy areas.
- Avoid scratching the rash.
