What causes yellowish discharge on underwear?

Yellowish discharge on underwear refers to the presence of yellowish secretions on the underwear. In most cases, yellow discharge on underwear may be caused by residual urine, post-exercise secretions, ovulation-related discharge, vaginitis, cervicitis, or other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified healthcare provider. Specific analyses are as follows:

1. Residual Urine

Human urine is acidic or alkaline and may leave small amounts of residue on underwear. Over time, this residue can accumulate and form yellowish stains. It is recommended to wipe thoroughly with toilet paper after urination and maintain the habit of changing underwear daily.

2. Post-Exercise Secretions

After intense physical activity, increased sweating may lead to yellowish-colored secretions. It is advisable to change clothes promptly after exercising, keep the external genital area dry, and prevent bacterial growth.

3. Ovulation-Related Discharge

During ovulation, elevated estrogen levels in women may result in increased vaginal discharge, which may sometimes appear yellowish. It is recommended to maintain good personal hygiene, change underwear frequently, and use mild cleansing products to clean the external genital area.

4. Vaginitis

Vaginitis is usually caused by bacterial invasion leading to imbalance in the vaginal microbial environment, which may result in abnormal overgrowth of anaerobic bacteria. The discharge may appear yellow and be accompanied by a fishy odor. Other symptoms commonly include increased discharge and unpleasant smell. Treatment should follow medical advice and may include medications such as metronidazole tablets, fluconazole tablets, or clindamycin hydrochloride gel.

5. Cervicitis

Cervicitis is caused by pathogen infection of the cervix. Inflammation may lead to increased discharge that appears yellow or purulent. Symptoms may also include cervical redness and swelling, lower back pain, and a sensation of pelvic pressure. Treatment should follow medical advice and may include medications such as ceftriaxone sodium for injection, cefixime capsules, or Jieeryin effervescent tablets.

In daily life, maintaining good personal hygiene, frequently changing undergarments, and preventing bacterial growth can effectively help prevent yellowish discharge on underwear.
