Pregnancy brings many changes to the body, including changes to the skin. While most pregnancy rashes are harmless and temporary, understanding what to expect can help you manage discomfort and know when to consult your doctor.
This guide outlines the most common pregnancy-related rashes, their typical symptoms, and safe treatment options.
Common Types of Pregnancy Rashes
Several skin conditions may develop during pregnancy, each with distinct features and timing:
Itchy red rash on the belly (PUPPP): one of the most common pregnancy rashes is called PUPPP. It usually starts in the third trimester as itchy, red bumps on the belly. It can spread to the thighs, arms, or buttocks. This rash is uncomfortable but not harmful to you or your baby.
Severe itching with no rash (Cholestasis of pregnancy): causes intense itching, often on the palms and soles without a visible rash. This is caused by changes in liver function during pregnancy and needs medical attention, as it may affect the baby’s health.
Blistering rash around the belly button: A rare condition called pemphigoid gestationis causes itchy blisters that usually start near the belly button and spread. It’s uncommon but should be checked by a gynaecologist.
Itchy spots that look like insect bites: Some pregnant women develop small, itchy red bumps on their arms, legs, or chest. These spots may show up in the second or third trimester and are typically mild and not harmful but can be bothersome.
Recognising Symptoms by Trimester
Understanding when symptoms appear can help identify the underlying condition:
First trimester rashes: are less common but may include early hormonal changes affecting existing skin conditions like eczema or psoriasis
Second trimester onset: new itchy bumps may start to appear around this time, especially if you’re expecting twins or more.
Third trimester development: most pregnancy-related rashes develop in the final few months. This includes PUPPP and liver-related itching. Symptoms may get more noticeable as your due date approaches.
Postpartum persistence: varies by condition, with some resolving immediately after birth whilst others may continue for several weeks
Treatment Options
If your rash doesn’t improve or if you’re concerned, it’s best to consult your gynaecologist. Some treatments may help, especially if itching is severe:
Topical corticosteroids: Mild anti-inflammatory creams (called steroid creams) may be prescribed to reduce swelling and redness. These are generally safe when used in small amounts during pregnancy.
Antihistamines: Some antihistamines are considered safe to use in pregnancy and may help with severe itch.
Monitoring for cholestasis: If cholestasis is suspected, your gynaecologist may recommend regular blood tests (liver function tests) or adjusted delivery timing
Dermatology referral: Blistering skin changes or uncertain diagnoses may require further evaluation by a dermatologist. This is further explored in the detailed guide to pregnancy rashes and treatment options.
Conclusion
Managing pregnancy rashes requires a balance of self-care measures and appropriate medical guidance. Most conditions resolve after delivery, and appropriate identification with treatment can improve comfort during pregnancy.
If you develop intense itching without visible rash, blistering lesions, or any skin changes that concern you, speak to your gynaecologist to help ensure appropriate care throughout pregnancy.
