What is the Difference Between Yeast Infection and Bacterial Infection?

The main difference between a yeast infection and a bacterial infection (bacterial vaginosis, or BV) lies in their causes, symptoms, and treatments. Here are the key differences:

Causes: Yeast infections are caused by an overgrowth of Candida fungus, while BV results from an overgrowth of harmful bacteria in the vagina.
Symptoms: Both infections can cause vaginal itching, burning sensations, and discomfort. However, yeast infections typically present with thick, white, odorless discharge, while BV causes thin, grayish, foamy discharge with a fishy odor.
Treatments: Yeast infections are typically treated with antifungal medications, while BV is treated with antibiotics.

It is essential to consult a healthcare provider for a proper diagnosis, as self-diagnosing and treating these infections can lead to complications or incorrect treatment.

Comparative Table: Yeast Infection vs Bacterial Infection

Here is a table comparing the differences between yeast infections and bacterial infections:

Feature	Yeast Infection	Bacterial Vaginosis
Causal Agent	Candida fungus (usually Candida albicans)	Gardnerella vaginalis bacteria
Risk Factors	Antibiotic use, weak immune system, pregnancy, diabetes, new or multiple sexual partners	Multiple sexual partners, unprotected sex, vaginal douching
Symptoms	Pain, discomfort, itching, difficulty urinating, abnormal discharge	Similar symptoms as yeast infections, but discharge is thin, grey, or white with a fishy odor
Diagnosis	Examination, sample of discharge for analysis	Examination, sample of discharge for analysis
Treatment	Antifungal medications (e.g., clotrimazole, miconazole)	Antibiotics (e.g., metronidazole, clindamycin)

Both yeast infections and bacterial vaginosis (BV) cause inflammation of the vagina, known as vaginitis, and share similar symptoms. However, they have different causal agents (fungus vs. bacteria) and risk factors. While BV is not considered a sexually transmitted infection, having it can increase a person's chances of getting sexually transmitted diseases.
