What causes miscarriage at 5 months?

1. Placental abruption

- In this condition, the placenta separates from the wall of the uterus before the baby is born, causing bleeding and depriving the baby of oxygen and nutrients.

- Risk factors: smoking, high blood pressure, drug abuse, advanced maternal age, multiparity, malnutrition

2. Cervical insufficiency (incompetent cervix)

- This is a condition in which the cervix is unable to hold the weight of the growing uterus, leading to premature dilation and expulsion of the baby.

- Risk factors: previous cervical surgery, multiple miscarriages, congenital anomalies of the cervix

3. Preeclampsia

- A pregnancy complication characterized by high blood pressure and protein in the urine.

- Risk factors: first pregnancy, multiple pregnancy, advanced maternal age, history of preeclampsia, chronic hypertension, diabetes, obesity.

4. Infection

- Infections such as listeriosis, toxoplasmosis, and rubella can cross the placenta and cause miscarriage at any stage of pregnancy.

5. Fetal anomalies

- Major structural or genetic abnormalities in the fetus can lead to miscarriage.

6. Maternal health conditions

- Certain medical conditions, such as uncontrolled diabetes, thyroid problems, autoimmune diseases, and uterine abnormalities, can increase the risk of miscarriage.

7. Lifestyle factors

- Smoking, excessive alcohol consumption, and illegal drug use can increase the risk of miscarriage.

8. Unexplained miscarriage

- In some cases, the cause of miscarriage remains unknown, despite extensive testing and evaluation.
