When women have hidden pain in the left lower abdomen, first of all, consider whether they are suffering from gynecological diseases. When inflammation or tumors appear in the pelvis and adnexa, the stimulation of inflammation will cause significant pain in the left lower abdomen, and when the pain is severe, gynecological ultrasound examination is required. Women of childbearing age check for ectopic pregnancy, corpus luteum rupture, pregnancy rupture, etc. Diseases in the female gastrointestinal tract, such as gastrointestinal spasm, colitis, abnormal bowel movements and blood in the stool, can be accompanied by pain in the left lower abdomen. Infection of the female urinary system and ureter and inflammatory stimulation can also cause pain in the abdomen, and ultrasound examination of the urinary tract is performed if necessary. It is recommended that women who have been experiencing vague pain in the lower left abdomen should take measures according to other symptoms of discomfort, go to the hospital for examination if necessary, pay attention to keeping the abdomen warm and avoid strenuous exercise.
