In women, lower abdominal swelling or a pulling sensation and flatulence may be caused by indigestion, pelvic inflammatory disease, pelvic effusion, and other factors. 1. Indigestion: In indigestion, food may accumulate in the gastrointestinal tract. At this time, the bacteria in the intestines may break down the food, thus producing large amounts of gas. When this gas travels to the colon, it may cause a woman’s lower abdomen to feel tugging and bloating. Symptoms can be relieved by moderate exercise to promote bowel movement. 2. Pelvic inflammatory disease: When pelvic inflammation occurs, the local inflammatory cells will release a large number of inflammatory mediators, and under the stimulation of these inflammatory mediators, women’s lower abdominal distension with tugging sensation and flatulence may occur. Symptoms can be relieved by medication, such as the use of amoxicillin, levofloxacin and metronidazole. 3. Pelvic effusion: when the ectopic pregnancy ruptures, pelvic blood accumulation may occur, and under the pressure of the blood accumulation, the symptoms of lower abdominal distension or tugging sensation and flatulence may occur. Symptoms can be relieved by surgical treatments such as salpingectomy and drainage of blood accumulation. There may be other reasons for women’s lower abdominal cramping or tugging sensation and flatulence. When women’s lower abdominal cramping or tugging sensation and flatulence occurs, they should consult a doctor and improve the examinations such as standing X-ray, bacteriological culture and vaginal ultrasound under the doctor’s guidance to clarify the cause and treat it actively.
