Odor in the pubic area may be related to vaginitis, pelvic inflammatory disease and reproductive organ tumors and other diseases. 1. Vaginitis: women will secrete leukorrhea, and the pubic area is often kept warm and moist, so if you don’t pay attention to local hygiene, it will easily lead to bacterial growth and cause vaginitis. When bacteria multiply in the vagina, odor will appear. 2. Pelvic inflammatory disease: when a woman suffers from pelvic inflammatory disease, under the stimulation of inflammatory factors, it will increase the secretion, and when the secretion is discharged along the vagina, a large amount of secretion is easy to trigger bacterial infection and odor. 3. Tumor of reproductive organs: such as cervical cancer, endometrial cancer, fallopian tube cancer, etc. Tumor grows fast, which can easily lead to ischemia and necrosis of local tissues and cause infection, leading to the appearance of large amount of abnormal secretion with foul smell. If you find bad smell in the pubic area, you should go to the hospital in time to do relevant examination, clarify the cause and then treat the cause.
