Can endometriosis cause miscarriage?

Endometriosis may increase the risk of miscarriage, but it is not the only factor that directly causes it.

The probability of miscarriage in patients with endometriosis is slightly higher than that in the general population, which is mainly related to pelvic inflammatory response, insufficient luteal function and reduced uterine receptivity. Ectopic lesions may cause local immune abnormalities and interfere with the embryo implantation process. When some patients are complicated with adenomyosis, structural changes in the myometrium may affect the embryonic development environment. For patients with mild disease and no other infertility factors, the risk of miscarriage after pregnancy is close to normal levels.

Patients with severe endometriosis have a relatively high risk of miscarriage, especially when combined with deep infiltrating lesions or reduced ovarian reserve. Anatomical abnormalities caused by lesions may increase uterine pressure, and chronic inflammatory states may affect placental formation. Patients undergoing assisted reproductive technology treatment need to pay attention to controlling the ovulation induction program to avoid hormonal fluctuations aggravating lesion activity.

It is recommended that patients with endometriosis undergo a detailed evaluation before pregnancy, including a gynecological examination, ultrasound and hormone level testing. After pregnancy, monitoring should be strengthened and progesterone and other miscarriage treatments should be supplemented in a timely manner. Maintain a regular schedule and avoid strenuous exercise and excessive tension on the pelvic floor muscles. Pay attention to supplementing vitamin E and Omega-3 fatty acids in the diet to help improve endometrial blood flow. If symptoms such as abdominal pain or vaginal bleeding occur, seek medical attention immediately.
