There are expected skin changes in pregnancy that may be a nuisance but do not require medical treatment. Sadly, there are a few skin conditions that do require medical input.

Our consultant dermatologist Dr Mary Sommerlad discusses them here, please note this is for your information only, remember to see a medical professional if you have any concerns.

Pemhigoid Gestationis: this is a rare autoimmune blistering disorder appearing usually in the second and third trimester although may occur earlier in subsequent pregnancies.

It manifests as intensely itchy, red or skin coloured or hyperpigmented bumps and blisters, typically starting around the navel and spreading to other areas of the torso and limbs. The face and mouth are usually spared. Prompt medical treatment is necessary.

Polymorphic Eruption of Pregnancy (PEP): this was formerly known as pruritic urticarial papules and plaques of pregnancy (PUPPP). It is a common condition occurring in the third trimester.

It features intensely itchy, red or hyperpigmented papules and plaques, often beginning within stretch marks and sparing the area around the navel. Medical treatment is necessary to relieve symptoms.

Prurigo of Pregnancy: This is characterised by itchy, crusted or excoriated papules (bumps) on the back of the arms and front of the legs (known as extensor surfaces) and trunk.

It can occur at any stage of pregnancy and may persist postpartum. Medical treatment is necessary to relieve symptoms

Intrahepatic Cholestasis of Pregnancy (ICP): This is a liver disorder that causes intense itching without a rash, typically in the third trimester. Itching often starts on the palms and soles before generalising.

ICP is associated with increased risks to the fetus, which requires close monitoring and treatment from the Obstetrics.

It’s crucial to remember that while this information provides a helpful overview of these specific pregnancy-related skin conditions, it should never replace a personalised consultation with a healthcare professional.
