Cellulitis in pregnancy
Informed by recognized medical guidance
Overview
Cellulitis is a bacterial skin infection that causes redness, swelling, warmth, and pain in the affected area. During pregnancy, your immune system is naturally weaker, which may make you more prone to infections like cellulitis.
Key facts
- Cellulitis can occur anywhere on the body but most often affects the legs, arms, or face.
- It is treated with antibiotics that are safe to use during pregnancy.
- Without treatment, the infection can spread to deeper tissues or the bloodstream, which is serious for both mother and baby.
Cellulitis is not very common in pregnancy, but it does happen. Pregnant women are at a slightly higher risk due to changes in the immune system and increased fluid in the body (edema).
It can affect any pregnant woman, especially those with breaks in the skin such as cuts, insect bites, tears, or areas of swelling.
Symptoms
- Fever with chills and shaking
- Rapid heart rate or breathing
- Confusion or feeling very unwell
- Redness spreading quickly even after starting treatment
- Difficulty moving the affected limb
- ⚠Redness that is growing in size
- ⚠You have a fever (temperature above 38°C or 100.4°F)
- ⚠You feel generally unwell or in pain
Common symptoms
- Redness that spreads over the skin
- Swelling and warmth in the affected area
- Pain or tenderness
- Fever and chills
Symptoms in children
- Cellulitis in pregnancy does not directly affect the unborn baby, but if the mother becomes very ill with a high fever or sepsis, it can affect the baby's health.
Symptoms in older adults
- This article focuses on pregnancy. In older adults, cellulitis can be more severe and take longer to heal.
Causes
Main causes
- Bacteria (most often streptococcus or staphylococcus) entering the skin through a cut, scratch, insect bite, or surgical wound
- Areas of swelling (edema) in pregnancy can make the skin more prone to infection
Risk factors
- Having a break in the skin, even a small one
- Being overweight or having diabetes
- Lymphedema (chronic swelling in a limb)
- Previous cellulitis
- Skin conditions like eczema that cause cracks in the skin
When to see a doctor
See a doctor urgently if:
- If you have a fever, redness spreading quickly, or feel very unwell, see a doctor or go to the nearest urgent care centre the same day.
Book a routine appointment if:
- If you have a small area of redness without fever, and it does not improve after 2 days of resting and elevating the area.
Diagnosis
Your doctor will examine your skin and ask about your symptoms and pregnancy. They will also check your temperature.
Tests that may be done
- Usually no tests are needed. Sometimes a blood test to check for infection or a swab of the skin to identify the bacteria.
What to expect at your appointment
The doctor will confirm if it is cellulitis and prescribe antibiotics that are safe during pregnancy. They may advise raising the affected area and taking rest.
Treatment
Cellulitis is treated with antibiotics to kill the bacteria. These are safe to take during pregnancy. You may also need rest and to elevate the affected area to reduce swelling.
Self-care at home
- Rest and elevate the infected limb (for example, on pillows) to reduce swelling.
- Drink plenty of fluids to help your body fight the infection.
- Keep the skin clean and dry. Do not scratch or pick at the area.
- Take paracetamol (if recommended by your doctor) for fever and pain.
Medical treatments
Your doctor will prescribe a course of antibiotics that is safe for you and your baby. Take all the doses as directed, even if you start feeling better. In severe cases, you may need antibiotics through a drip in hospital.
When is surgery considered?
Very rarely, if an abscess (a pocket of pus) forms, a doctor may need to drain it with a small procedure.
Living with this condition
While you have cellulitis, you may need to rest more and avoid standing for long periods. Continue with your regular antenatal check-ups and let your midwife or doctor know about the infection.
Lifestyle tips
- Rest the affected area as much as possible.
- Elevate it when sitting or lying down.
- Wear loose clothing to avoid rubbing.
- Do not use hot compresses unless your doctor advises.
Diet and exercise
Eat a healthy, balanced diet to support your immune system. Gentle walking is usually fine, but avoid exercise that puts pressure on the infected area.
Mental health and emotional wellbeing
Having an infection during pregnancy can be worrying. Talk to your midwife or doctor about any concerns. It's normal to feel anxious, and support is available.
Prevention
You can lower the risk by cleaning and covering any cuts, scratches, or insect bites. If you have leg swelling (edema) during pregnancy, ask your midwife about ways to manage it, such as elevating your legs.
Vaccines
There is no vaccine specifically for cellulitis, but staying up to date with vaccines such as tetanus can help prevent infections from wounds.
Screening programmes
No routine screening is done for cellulitis. Your doctor may check your skin if you have a history of cellulitis or a higher risk.
Complications
If left untreated
- The infection can spread into the bloodstream, causing sepsis (a life-threatening reaction).
- It can also spread to deeper tissues (necrotizing fasciitis), which is very serious.
- For the baby, severe infection in the mother can lead to preterm labour or low birth weight.
Long-term outlook
With prompt antibiotic treatment, most cases of cellulitis in pregnancy improve within a week. The outlook is very good. Taking the full course of antibiotics and following your doctor's advice helps prevent the infection from returning.
