What causes yellow discharge after intercourse postpartum, and what should be done?
Yellowish discharge after intercourse during the postpartum period may result from incomplete resolution of lochia, irritation during vaginal mucosal healing, vaginitis, pelvic inflammatory disease, or acute urethritis. Symptoms can be improved through proper hygiene, avoiding irritants, and medical treatment. If the discharge is accompanied by odor, itching, or abdominal pain, prompt medical attention is recommended.
1. Incomplete resolution of postpartum lochia: During uterine recovery after childbirth, small amounts of residual lochia may remain and be expelled following sexual intercourse, appearing as light yellow discharge in small quantity without odor. It is recommended to maintain external genital cleanliness, change underwear frequently, wash the external genital area with warm water after intercourse, and avoid frequent intercourse.
2. Irritation during vaginal mucosal healing: The vaginal mucosa may not be fully healed after childbirth. Friction during intercourse can increase mucosal exudation, resulting in light yellow discharge that may be accompanied by mild burning sensation. It is advised to refrain from intercourse until the mucosa has completely healed, avoid spicy foods, and minimize local irritation.

3. Vaginitis: Reduced immunity after childbirth may lead to bacterial or candidal infections causing inflammation, resulting in yellow, thick discharge accompanied by vulvar itching and odor. Under a doctor's guidance, medications such as metronidazole suppositories, clotrimazole suppositories, or Honghe Fuyan cleansing solution can be used to relieve symptoms.
4. Pelvic inflammatory disease: Infection of pelvic tissues after childbirth causes inflammation, leading to yellowish discharge accompanied by lower abdominal heaviness and low back or sacral pain. Under medical supervision, patients may take medications such as cefixime dispersible tablets, levofloxacin hydrochloride capsules, or Fuyankang tablets to alleviate discomfort.
5. Acute urethritis: Poor hygiene after childbirth may allow bacteria to invade the urethra, causing inflammation with yellow urethral discharge, frequent urination, urgency, and dysuria. As directed by a physician, medications such as amoxicillin capsules, cefaclor capsules, or Sanjin tablets may be used to improve symptoms.
Maintain clean and dry external genitalia, frequently change into breathable underwear, practice good hygiene before and after intercourse, follow a light and easily digestible diet, drink plenty of warm water, and maintain regular sleep patterns to support recovery and reduce discomfort.
