How is candidal vaginitis caused?

In general, candidal vaginitis refers to vulvovaginal candidiasis, which may be associated with various factors such as poor hygiene habits, sexual contact, pregnancy, weakened immunity, and diabetes. It is recommended to seek medical attention promptly and receive treatments under a doctor's guidance, including general management and medication. Specific analyses are as follows:

1. Poor Hygiene Habits

Poor hygiene practices—such as excessive vaginal douching, failure to change underwear regularly, and inadequate perineal hygiene—can create favorable conditions for the growth of Candida yeast, leading to vulvovaginal candidiasis. It is important to maintain good personal hygiene, wear breathable cotton underwear, and avoid using scented hygiene products.

2. Sexual Contact

Vulvovaginal candidiasis can be transmitted through sexual contact. If one partner is infected with Candida, the pathogen may be introduced into the other partner’s body during sexual activity, potentially causing infection. Protective measures should be taken during sexual intercourse.

3. Pregnancy

Hormonal changes during pregnancy can alter the vaginal environment, making it more conducive to Candida growth. In particular, elevated estrogen levels during pregnancy promote conditions favorable for yeast proliferation, potentially resulting in vulvovaginal candidiasis. Symptoms often include vaginal itching, increased vaginal discharge, and a burning sensation. Treatment may include clotrimazole suppositories, miconazole nitrate cream, or ornidazole capsules, used as directed by a physician.

4. Weakened Immunity

Weakened immunity is primarily caused by malnutrition, high stress levels, overuse of antibiotics, and aging. A compromised immune system reduces the body’s ability to effectively eliminate Candida, allowing it to multiply excessively in the vagina and cause infection. Symptoms may include itching, abnormal vaginal discharge, and others mentioned above. Treatments may include fluconazole injection, ketoconazole cream, or fluconazole capsules, used as prescribed.

5. Diabetes

Diabetes may result from pancreatic cell dysfunction, genetic predisposition, environmental factors, and immune system defects. The high blood glucose levels in diabetic patients provide abundant nutrients for Candida, and combined with reduced immune function, increase susceptibility to vulvovaginal candidiasis. Common symptoms include vaginal itching, increased discharge, frequent urination, and thirst. Medications such as metformin tablets, gliclazide modified-release tablets, or rosiglitazone hydrochloride tablets may be used under medical supervision.

In daily life, it is essential to maintain good hygiene practices, avoid indiscriminate use of medications, and strengthen the immune system.
