what is abortion?
Abortion is the termination or expulsion of a pregnancy before the fetus becomes viable and capable of independent life outside the uterus
causes of abortion
fetal causes
- Chromosomal abnormalities,Abnormal chromosomes prevent normal fetal development.
- Genetic defects ,Gene mutations cause severe developmental abnormalities.
- Congenital malformations ,Serious birth defects make survival impossible.
- Blighted ovum .The gestational sac develops, but the embryo does not.
- Molar pregnancy ,Abnormal fertilization leads to abnormal placental growth instead of a normal fetus.
- Intrauterine fetal death,The fetus dies in the uterus before birth.
- Abnormal embryonic development ,The embryo fails to develop normally.
- Multiple fetal anomalies ,Several severe defects affect the fetus simultaneously.
- Placental developmental defects ,Poor placental formation limits oxygen and nutrient supply.
- Fetal infections , Infections damage the fetus and may cause pregnancy loss.
Maternal Causes of Abortion
- Hormonal imbalances ,affect implantation and pregnancy maintenance.ie eostrogen and progesterone
- Diabetes mellitus ,poor control leads to fetal damage and miscarriage.
- Thyroid disorders ,disrupt normal fetal growth and pregnancy support.
- Severe anemia ,reduces oxygen supply to the fetus.
- Hypertension.decreases placental blood flow.
- Maternal infections damage the fetus (e.g., malaria, syphilis).
- Uterine/cervical problems ,structural defects or weak cervix cause pregnancy loss.
- Uterine fibroids,interfere with implantation and fetal development.
- Malnutrition & substance abuse ,impair fetal growth and survival.
- Systemic & environmental factors ,chronic illness, stress, advanced age, previous miscarriages, and exposure to toxins increase risk of abortion.
- Trauma direct blow to the gravid uterus
- unwanted pregnancy
Types of Abortion

- Infection that can progress sepsis especially if unsterile instrument use.
- Organ injury ,damage to the uterus and cervix.
- Infertility ,future inability to conceive due to complications.
- Ectopic pregnancy risk,increased risk in future pregnancies.
- Chronic pelvic pain,long-term abdominal discomfort.
- Menstrual disorders,irregular or painful periods.
- Psychological effects ,anxiety, depression, or emotional distress.
- Maternal death especially in unsafe abortion.
- Social problems like stigma, relationship issues, and financial burden.
Prevention of Abortion
- Family planning and contraception ,prevents unintended pregnancies.
- Early antenatal care (ANC),early detection and management of risks.
- Treatment of maternal diseases ,control of diabetes, hypertension, anemia, and thyroid disorders.
- Prevention of infections,screening, treatment, and good hygiene.
- Healthy lifestyle,eat balanced diet, rest well, and do moderate exercise.
- Avoid harmful substances like alcohol, smoking, drugs, or toxins.
- Avoid physical trauma ,prevent heavy work and anything that can lead to abdominal injury.
- Health education and counseling to create awareness on pregnancy care and danger signs.
- High-risk pregnancy care ,close monitoring of mother of high risk of abortion like
- Psychological support ,stress management and emotional care.
