How can I tell if it is vaginitis or a vaginal yeast infection?
Both bacterial vaginitis (colpitis) and a vaginal yeast infection (vaginal mycosis) can be accompanied by discharge, itching, and burning. The main difference lies in the type of discharge and the skin condition in the intimate area. While a bacterial infection often causes a thin, gray-white, unpleasant-smelling discharge, a vaginal yeast infection typically shows a whitish, crumbly, odorless discharge accompanied by intense itching. Additionally, with yeast infections, the outer labia are often strongly reddened and swollen, which is less common in bacterial colpitis.

How do the symptoms differ between yeast infection and bacterial vaginosis?
A vaginal yeast infection usually causes strong itching, a Burning when urinating as well as a clearly visible redness and swelling of the vulva. Bacterial vaginosis, on the other hand, is more characterized by increased discharge with a fishy odor, without severe irritation of the external mucous membranes. Pain during sex can occur in both forms, but is more common with yeast infections due to mechanical friction, while in colpitis the mucous membrane generally reacts more sensitively.

What color and consistency does the discharge have in a yeast infection compared to colpitis?
Vaginal discharge often provides the first clue to the underlying cause. In a yeast infection, the discharge is usually whitish, curd-like, or creamy, odorless, and difficult to wipe away. In bacterial vaginitis, on the other hand, the discharge appears gray-yellowish, thin, and often has an unpleasant odor. Additionally, discharge in a mixed infection can be foamy or greenish, especially with trichomonads.

Does the discharge smell different in a yeast infection than in bacterial vaginitis?
Yes, and this difference is clinically very relevant. Bacterial vaginosis is typically associated with a fishy, unpleasant odor that is especially noticeable after sexual intercourse or during menstruation. The discharge in a vaginal yeast infection, on the other hand, usually remains neutral in odor. If an originally odorless discharge suddenly develops an unpleasant smell, this may indicate an additional bacterial infection.
What causes more itching – vaginal inflammation or yeast infection?
The most intense itching usually occurs with a yeast infection. The mucous membrane is not only irritated but reacts allergically to the yeast colonization, leading to severe scratching, burning, and in some cases even small cracks. In bacterial vaginosis, itching is rather rare or mild. If itching is prominent in colpitis, this may indicate a mixed infection or additional irritation from hygiene products.
How reliably can I distinguish myself whether I have a yeast infection or a bacterial infection?
The distinction is often not clear for laypeople, as some symptoms overlap. A typical yeast infection is usually easy to recognize when itching, redness, white coating, and odorless discharge occur together. In cases of atypical or mild symptoms, especially with altered pH values or unpleasant odor, a medical examination through microscopic smear or pH test is advisable. pH test strips are available in pharmacies and can provide clues about the type of infection.
What role does pH value play in distinguishing between colpitis and yeast infection?
The pH value of the vagina in healthy women is acidic (3.8–4.5). In bacterial vaginosis, the pH value rises above 4.5 because the lactic acid bacteria are displaced. In yeast infections, the pH value usually remains unchanged, which is an important diagnostic aid.

Can a bacterial vaginal infection occur simultaneously with a yeast infection?
Yes, so-called mixed infections are not uncommon. Especially after antibiotic therapies or with disturbed vaginal flora, fungi and bacteria can settle simultaneously. Treatment then becomes more complex, as both an antifungal and an antibiotic or an antiseptic combination preparation may be necessary. In addition, pH-regulating and regenerating preparations, such as CANNEFF® suppositories with CBD and hyaluronic acid, should be used for mucous membrane care and flora stabilization, especially if vaginal dryness occurs during and after treatment.
Which treatment helps with yeast infections—and which with bacterial infections?
For a vaginal yeast infection, local antifungals such as clotrimazole or miconazole are used—usually as suppositories or cream. For a bacterial infection, metronidazole or clindamycin are preferred, sometimes as vaginal gel or tablets. Additionally, the use of lactic acid preparations can be useful to restore the acidic environment.

When should I definitely see a gynecologist for unclear symptoms?
A doctor visit is always recommended if the symptoms persist for more than three days, recur, worsen, or if fever, bleeding, or pain occur. A gynecological examination should also be obtained during pregnancy, at the first occurrence, or if self-treatment does not lead to improvement.
