What causes lower abdominal bloating and pain along with increased vaginal discharge in women?

Lower abdominal discomfort or pain accompanied by increased vaginal discharge in women can stem from a variety of gynecologic and non-gynecologic conditions. Common causes include bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis—each associated with characteristic changes in discharge (e.g., thin grayish odoriferous discharge in bacterial vaginosis; thick, curd-like discharge in candidiasis; or frothy, yellow-green, malodorous discharge in trichomoniasis). Pelvic inflammatory disease (PID), often resulting from untreated chlamydial or gonococcal infection, may present with lower abdominal pain, fever, cervical motion tenderness, and purulent discharge. Other considerations include cervical ectropion, endometritis, or subclinical pelvic adhesions. Less commonly, gastrointestinal disorders such as irritable bowel syndrome or constipation, or urinary tract issues like cystitis, may mimic or coexist with gynecologic symptoms. A thorough clinical evaluation—including history, pelvic examination, wet mount microscopy, nucleic acid amplification testing (NAAT) for *Chlamydia trachomatis* and *Neisseria gonorrhoeae*, and possibly transvaginal ultrasound—is essential to determine the underlying etiology and guide appropriate treatment.
