10 Common Triggers of Left Abdominal Discomfort

6. Gynecological Conditions

Several gynecological conditions can cause left side of the abdomen pain.

• Ovarian cysts are fluid-filled pockets in the ovary. They are common and most resolve on their own, though they may cause abdominal discomfort.
• Mittelschmerz or ovulation pain occurs midway through a women's menstrual cycle when the ovary releases an egg. It is normal and rarely requires medical intervention.
• Ectopic pregnancy is a more dangerous cause of left-sided abdominal pain and occurs when a fertilized egg implants into the fallopian tube instead of the uterus. This condition is life-threatening as it can cause the fallopian tube to rupture. Pelvic pain and light spotting or bleeding are other signs of an ectopic pregnancy.
