Differential Diagnosis for a 5-Month Pregnant Woman with White Discharge
Single Most Likely Diagnosis
- Leukorrhea: A common condition in pregnancy characterized by a thick, white, or off-white vaginal discharge. It is caused by hormonal changes and increased blood flow to the vagina. The absence of pain, bleeding, and normal vitals supports this diagnosis.
Other Likely Diagnoses
- Yeast Infection (Candidiasis): A fungal infection that can cause a white, cottage cheese-like discharge. Although it's typically accompanied by itching and irritation, some cases may be asymptomatic.
- Bacterial Vaginosis (BV): A bacterial infection that can cause a thin, white, or gray discharge with a fishy odor. However, the absence of odor and other symptoms makes this less likely.
- Trichomoniasis: A sexually transmitted infection that can cause a frothy, white, or yellow-green discharge. The lack of symptoms like itching, burning, and abdominal pain makes this less likely.
Do Not Miss Diagnoses
- Chlamydia: A sexually transmitted infection that can cause a white discharge, although it's often asymptomatic. If left untreated, it can lead to serious complications like preterm labor and neonatal infection.
- Gonorrhea: Another sexually transmitted infection that can cause a white discharge. Like chlamydia, it can have severe consequences if not treated promptly.
- Group B Streptococcus (GBS) Infection: A bacterial infection that can cause a white discharge. GBS can lead to serious illness in the newborn if not properly managed during delivery.
Rare Diagnoses
- Human Papillomavirus (HPV): Although HPV is a common infection, it rarely causes a white discharge. It's more commonly associated with cervical dysplasia and cancer.
- Cervical Cancer: A rare but potentially life-threatening condition that can cause abnormal vaginal discharge, including white discharge. However, it's unlikely to present with no other symptoms.
