Yeast infections late in pregnancy are common and treatable, but prompt care is essential to avoid discomfort and complications.
Understanding Yeast Infection At 37 Weeks Pregnant
Yeast infections, medically known as candidiasis, occur when the natural balance of yeast and bacteria in the vagina is disrupted. At 37 weeks pregnant, a woman is considered full-term, and her body undergoes significant hormonal changes that can increase the risk of developing a yeast infection. The hormone progesterone rises during pregnancy, creating an environment that encourages yeast overgrowth. This makes yeast infections more frequent and sometimes more severe during this stage.
The symptoms typically include intense itching, burning sensations, redness, swelling around the vulva, and a thick white discharge often described as cottage cheese-like. These symptoms can cause discomfort and anxiety for expectant mothers already preparing for childbirth.
Why Yeast Infections Are More Common Late in Pregnancy
Pregnancy triggers a cascade of hormonal shifts designed to support fetal growth. Estrogen levels surge throughout pregnancy, peaking near term. Estrogen increases glycogen in vaginal cells, which acts as food for Candida albicans—the fungus responsible for most yeast infections. This creates an ideal breeding ground for yeast.
Moreover, the immune system is naturally suppressed during pregnancy to prevent rejection of the fetus. This immunosuppression reduces the body’s ability to fight off fungal infections effectively.
Other factors contributing to yeast infection at 37 weeks pregnant include:
- Increased vaginal moisture: Hormonal changes lead to increased vaginal secretions.
- Antibiotic use: Antibiotics taken during pregnancy can disrupt normal bacterial flora.
- Diabetes or gestational diabetes: High blood sugar levels promote fungal growth.
- Tight or synthetic clothing: These can trap moisture and heat, fostering yeast growth.
The Impact on Mother and Baby
While uncomfortable for the mother, a typical vaginal yeast infection rarely causes harm to the baby directly. However, untreated infections near delivery can increase the risk of passing the infection to the newborn during birth. Newborns exposed to Candida may develop oral thrush or diaper rash shortly after delivery.
Additionally, severe itching and discomfort can affect a mother’s sleep quality and stress levels just before labor—a time when rest is crucial.
Treatment Options Safe for Yeast Infection At 37 Weeks Pregnant
Treating a yeast infection at this late stage requires careful consideration because certain medications are not recommended during pregnancy. The primary goal is to relieve symptoms quickly while ensuring safety for both mother and baby.
Topical Antifungal Medications
Topical antifungals are considered safe and effective during pregnancy. These include creams or suppositories containing:
- Clotrimazole
- Miconazole
- Terconazole
These medications are applied directly inside the vagina or on external areas affected by irritation. Treatment usually lasts between 3-7 days depending on severity.
Avoid Oral Antifungal Drugs
Oral antifungal medications like fluconazole are generally avoided in pregnancy because of potential risks to fetal development. Unless prescribed under strict medical supervision in severe cases, oral options should be off-limits.
Home Remedies That Help Relieve Symptoms
While medical treatments are best for clearing infections quickly, some home strategies may ease discomfort:
- Cotton underwear: Breathable fabrics reduce moisture buildup.
- Avoid scented soaps or douches: These irritate sensitive skin.
- Sitz baths with warm water: Can soothe itching temporarily.
- Maintain good hygiene: Keep genital area clean and dry.
However, home remedies alone won’t cure an infection; professional treatment remains necessary.
Differentiating Yeast Infection From Other Pregnancy-Related Issues
Not every vaginal irritation or discharge indicates a yeast infection—especially late in pregnancy when other conditions may mimic similar symptoms.
Bacterial Vaginosis (BV)
BV is caused by an imbalance of bacteria rather than fungus. It usually produces a thin grayish discharge with a fishy odor rather than thick white discharge seen in candidiasis.
Group B Streptococcus (GBS) Colonization
GBS is a bacterial presence that doesn’t cause symptoms but requires screening at around 36-37 weeks due to its potential risk to newborns during delivery.
Preterm Labor Signs vs. Infection Symptoms
Sometimes vaginal discomfort might be confused with early labor signs such as cramping or increased discharge. It’s important not to overlook any new symptoms at this stage without consulting your healthcare provider promptly.
The Role of Healthcare Providers in Managing Yeast Infection At 37 Weeks Pregnant
Medical professionals play a crucial role in diagnosing and treating late-pregnancy yeast infections safely:
- Accurate diagnosis: A pelvic exam combined with laboratory testing confirms candidiasis versus other infections.
- Treatment guidance: Providers prescribe safe antifungal treatments appropriate for late pregnancy.
- Monitoring complications: Ensuring that symptoms resolve before labor starts reduces neonatal risks.
- Counseling on prevention: Educating about hygiene practices minimizes recurrence chances.
Never self-diagnose or self-treat at this stage without medical advice due to overlapping symptoms with other potentially serious conditions.
Nutritional and Lifestyle Tips To Prevent Recurrence
Preventing recurrent yeast infections involves lifestyle adjustments that support vaginal health:
| Nutritional Tips | Lifestyle Changes | Avoid These Triggers |
|---|---|---|
| Avoid excessive sugar intake which feeds yeast growth. Cultivate probiotics through yogurt or supplements. Stay hydrated for overall health. |
Wear loose-fitting cotton underwear. Avoid prolonged damp clothing like wet swimsuits. Practice gentle cleansing without harsh soaps. |
Synthetic fabrics trapping heat. Scented feminine products. Avoid unnecessary antibiotic use without prescription. |
These measures help maintain natural flora balance while reducing irritation risks.
Addressing a yeast infection promptly at 37 weeks pregnant ensures comfort going into labor and guards against neonatal exposure during birth. Untreated infections could complicate labor by increasing inflammation or causing additional irritation that might interfere with medical exams or interventions needed during delivery.
Healthcare providers emphasize completing treatment courses fully even if symptoms improve early on because incomplete treatment can lead to resistant strains or relapse after birth.

Frequently Asked Questions
What causes a yeast infection at 37 weeks pregnant?
At 37 weeks pregnant, hormonal changes like increased progesterone and estrogen create an environment that encourages yeast overgrowth. The rise in vaginal glycogen and suppressed immune system during late pregnancy also contribute to the higher risk of developing a yeast infection.
What are the symptoms of a yeast infection at 37 weeks pregnant?
Common symptoms include intense itching, burning sensations, redness, swelling around the vulva, and a thick white discharge that looks like cottage cheese. These symptoms can cause significant discomfort during the final weeks of pregnancy.
Is it safe to treat a yeast infection at 37 weeks pregnant?

Can a yeast infection at 37 weeks pregnant affect my baby?
While yeast infections rarely harm the baby directly, untreated infections near delivery may increase the chance of passing Candida to the newborn. This can cause oral thrush or diaper rash in the baby shortly after birth.
How can I prevent a yeast infection at 37 weeks pregnant?
To help prevent yeast infections, wear loose, breathable clothing and avoid synthetic fabrics. Maintaining good hygiene, avoiding unnecessary antibiotics, and managing blood sugar levels if diabetic can also reduce the risk of developing an infection at this stage.
