What causes lower abdominal distension and pain after intercourse?

Lower abdominal distension and pain after intercourse may result from excessive movement during intercourse, pelvic congestion during intercourse, pelvic inflammatory disease (PID), endometritis, or adnexitis. Symptoms can be alleviated through rest, adjusting sexual positions, and targeted medication. However, if the discomfort persists or recurs frequently, prompt medical consultation is advised.

1. Excessive movement during intercourse: Overly vigorous movements or inappropriate positions may stretch pelvic ligaments and irritate intra-abdominal organs, causing transient lower abdominal heaviness and pain post-intercourse. It is recommended to slow down movements during intercourse, adopt gentle and comfortable positions, and rest in bed with limited activity while symptoms persist.

2. Pelvic congestion during intercourse: Increased pelvic blood flow during intercourse leads to physiological pelvic congestion, resulting in mild swelling of pelvic tissues and a dull, achy sensation in the lower abdomen. After intercourse, lying supine and applying warm compresses to the lower abdomen, drinking ample warm water, and avoiding prolonged sitting or standing are advised to facilitate recovery of normal pelvic circulation.

3. Pelvic inflammatory disease (PID): Bacterial infection of the pelvis causes inflammatory edema; sexual stimulation exacerbates local congestion, leading to persistent lower abdominal distension and pain, often accompanied by increased vaginal discharge. Under physician guidance, medications such as Fuke Qianjin Tablets, Cefixime Capsules, and Kangfu Xiaoyan Suppositories may be used to alleviate symptoms.

4. Endometritis: Mild inflammation renders the endometrium fragile and hyperemic; sexual stimulation may trigger lower abdominal heaviness and pain, and some individuals may experience worsening menstrual cramps. Under medical supervision, Metronidazole Tablets, Jin Gang Teng Capsules, and Amoxicillin Capsules may help relieve discomfort.

5. Adnexitis: Mild inflammation of the fallopian tubes and ovaries may cause traction on surrounding tissues; mechanical stimulation during intercourse may aggravate inflammation, resulting in unilateral or bilateral lower abdominal distension and pain, which may worsen with fatigue. As prescribed, Levofloxacin Tablets, Hua Hong Tablets, and Kushen Gel may be used to improve symptoms.

Routine care includes maintaining genital hygiene, keeping the external genitalia dry and well-ventilated, ensuring warmth for the waist and abdomen, limiting intake of cold, raw, or spicy foods, maintaining regular sleep-wake cycles, engaging in moderate physical exercise, and promoting balanced regulation of pelvic health.
