Discharge, trichomoniasis infection?


For the past six months, I have been experiencing a yellowish-green discharge resembling mucus a few days before my menstrual period, and the amount is somewhat significant—sometimes my underwear is completely soiled.
The odor is also unpleasant.
However, this discharge disappears after my period, replaced by a small amount of white, cottage cheese-like discharge, which also has an unpleasant smell.
Could you please explain what might be causing this and how I can improve the situation? I am currently taking oral contraceptives; could this be related? Thank you for your hard work, doctor.

Hello, Xiro: This is a vaginal bacterial infection.
It is recommended to use vaginal suppositories, topical ointments, and antibiotics for treatment.
This is not directly related to the contraceptive pills taken beforehand.

Understanding abnormal vaginal discharge is crucial for maintaining reproductive health. The symptoms you describe—yellow-green, mucus-like discharge with an unpleasant odor before your menstrual period, followed by a white, curd-like discharge after menstruation—can be indicative of several underlying conditions.
Firstly, the yellow-green discharge you experience prior to menstruation could suggest a possible infection, such as bacterial vaginosis (BV) or a sexually transmitted infection (STI) like trichomoniasis. Bacterial vaginosis is characterized by an imbalance in the normal bacterial flora of the vagina, leading to an increase in certain bacteria and a decrease in others. This condition often results in a fishy odor and can produce a thin, grayish discharge, but it can also present as yellow-green in some cases. Trichomoniasis, on the other hand, is caused by a parasite and can lead to a frothy, yellow-green discharge, often accompanied by itching and irritation.

The white, curd-like discharge you notice after your period is typically associated with a yeast infection, particularly if it is thick and has a cottage cheese-like consistency. Yeast infections are caused by an overgrowth of Candida, a type of fungus that normally resides in the vagina in small amounts. Factors that can contribute to yeast infections include hormonal changes, antibiotic use, and certain medical conditions like diabetes.

Regarding your use of oral contraceptives, it is important to note that hormonal fluctuations can influence vaginal discharge. Birth control pills can alter the natural balance of hormones, which may lead to changes in the vaginal environment and potentially contribute to abnormal discharge. However, they are not directly responsible for infections but can affect the body's susceptibility to them.

To improve your situation, consider the following steps:
1. Consult a Healthcare Provider: It is essential to see a gynecologist or healthcare provider for a thorough examination. They can perform tests to determine if you have an infection and prescribe appropriate treatment.

2. Maintain Good Hygiene: Practice good vaginal hygiene by washing the external genital area with mild soap and water. Avoid douching, as it can disrupt the natural balance of bacteria in the vagina.

3. Wear Breathable Fabrics: Opt for cotton underwear and avoid tight-fitting clothing to reduce moisture and irritation in the vaginal area.

4. Monitor Symptoms: Keep track of your symptoms, including the timing, consistency, and odor of your discharge. This information can be helpful for your healthcare provider.

5. Consider Probiotics: Some studies suggest that probiotics may help restore the natural flora of the vagina, potentially reducing the risk of infections.

6. Avoid Irritants: Be cautious with scented products, such as soaps, lotions, and feminine hygiene sprays, as they can irritate the vaginal area.

7. Diet and Lifestyle: A balanced diet and healthy lifestyle can support your immune system, which plays a role in preventing infections.

In conclusion, while hormonal contraceptives can influence vaginal discharge, they are not the sole cause of abnormal discharge. A proper diagnosis from a healthcare provider is crucial to determine the underlying cause and appropriate treatment. By taking proactive steps and seeking medical advice, you can effectively manage your symptoms and maintain your reproductive health.
