Underwear often smells bad

Frequent odor from underwear may be caused by poor hygiene habits, vaginitis, cervicitis, or other factors. Appropriate measures should be taken based on the specific situation. The detailed analysis is as follows:

1. Poor Hygiene Habits

Underwear comes into direct contact with the skin of the genital area. Substances such as vaginal secretions and urine can remain on the surface of the underwear. If not changed regularly, this may lead to the growth of odor-causing bacteria, resulting in persistent unpleasant smell. It is recommended to choose cotton underwear, change it frequently, and wash it with clean water to develop good hygiene habits.

2. Vaginitis

Individuals who engage in frequent sexual activity may develop vaginitis if proper cleaning is not performed before and after intercourse. Bacteria adhering to the genital area may enter the body, triggering an inflammatory response. Inflammatory factors can stimulate the vaginal mucosa, increasing secretions and causing the aforementioned symptoms. Patients are advised to use medications such as metronidazole clotrimazole effervescent tablets or ornidazole vaginal suppositories under a doctor's guidance.

3. Cervicitis

Cervicitis is mostly caused by pathogen infection. Most patients are asymptomatic, but some may experience increased vaginal discharge, intermenstrual bleeding, or postcoital bleeding. These conditions may contribute to the occurrence of smelly underwear. Patients are advised to take medications such as cefprozil tablets or cefixime dispersible tablets as prescribed by a physician.

In addition, conditions such as cervical polyps, uterine fibroids, or endometrial cancer could also be potential causes. It is recommended to maintain regular sleep patterns, engage in appropriate physical exercise, and enhance overall health.
