Flesh-like material discharged from menstrual blood is a clinical abnormality. Normal menstrual blood is dark red non-clotting blood, and the discharge of fleshy material in menstrual blood is often due to excessive activity of the endometrium or inflammation of the endometrium, which results in a large piece of the endometrium falling off, and the endometrium is discharged from the vagina with the menstrual blood, which manifests itself as the discharge of fleshy material, and it may be accompanied by more severe menstrual cramps, which are significantly alleviated after the fleshy material has been discharged. In addition, in clinical cases where menopause is actually a miscarriage caused by pregnancy, the fleshy tissue discharged is actually embryonic tissue, which is mistaken for menstruation. It is recommended to go to the hospital for blood HCG test or urine HCG test to find out whether it is caused by miscarriage, and ultrasound should also be done to find out whether there are still residual tissues in the uterine cavity, and treat accordingly.
