Six High-Risk Pregnancy Conditions Every Expectant Mother Should Know

Understanding possible complications and attending regular antenatal appointments can help doctors detect problems early and provide appropriate care.

1. Molar Pregnancy

A molar pregnancy is an abnormal pregnancy caused by an error during fertilisation. Instead of developing into a healthy pregnancy, placental tissue grows abnormally and may form clusters of fluid-filled sacs inside the uterus.

There are two main forms:

๐ A complete molar pregnancy, in which no normal embryo develops

๐ A partial molar pregnancy, in which abnormal foetal tissue may be present but cannot develop normally

Possible symptoms include:

๐ Vaginal bleeding during early pregnancy

๐ Severe nausea and vomiting

๐ A uterus that is larger than expected for the stage of pregnancy

๐ Abnormally high pregnancy hormone levels

๐ Pelvic pressure or discomfort

Symptoms commonly appear during the first trimester. Heavy bleeding may cause weakness, dizziness, or fainting and requires urgent medical care.

2. Placenta Previa

Placenta previa occurs when the placenta attaches unusually low in the uterus and partially or completely covers the opening of the cervix.

The most common sign is painless vaginal bleeding during the second or third trimester.

Risk factors may include:

๐ Previous caesarean delivery

๐ Previous uterine surgery or curettage

๐ Multiple pregnancy

๐ Previous placenta previa

๐ Advanced maternal age

๐ Smoking

Women diagnosed with placenta previa require close monitoring because the condition may cause severe bleeding and affect the safest method and timing of delivery.

3. Gestational Diabetes

Gestational diabetes develops when hormonal changes during pregnancy reduce the body’s response to insulin, causing blood glucose levels to rise.

It can occur even in women who have never previously had diabetes.

Poorly controlled gestational diabetes may increase the risk of:

๐ A larger-than-average baby

๐ Difficult delivery or birth injury

๐ Caesarean delivery

๐ Premature birth

๐ High blood pressure or pre-eclampsia

๐ Low blood sugar in the newborn after delivery

๐ Breathing problems in the newborn

Treatment may include dietary changes, physical activity, blood glucose monitoring, and medication or insulin when necessary.

4. Threatened Miscarriage

A threatened miscarriage refers to vaginal bleeding during early pregnancy while the cervix remains closed and the pregnancy may still be viable.

Possible symptoms include:

๐ Light or moderate vaginal bleeding

๐ Lower abdominal discomfort

๐ Pelvic cramping

๐ Lower back pain

Possible causes or associated factors include chromosomal abnormalities, hormonal problems, uterine conditions, infection, or underlying maternal disease. In many cases, however, the exact cause cannot be identified.

Not every episode of bleeding results in miscarriage, but medical assessment is essential to confirm the location and condition of the pregnancy.

Heavy bleeding, severe abdominal pain, fainting, shoulder pain, or passing tissue requires immediate medical attention.

5. Pre-Eclampsia

Pre-eclampsia is a pregnancy complication involving high blood pressure and signs that organs such as the kidneys, liver, brain, or placenta may be affected. It usually develops after 20 weeks of pregnancy.

Possible warning signs include:

๐ High blood pressure

๐ Protein in the urine

๐ Sudden swelling of the face or hands

๐ Severe or persistent headache

๐ Blurred vision or flashing lights

๐ Pain beneath the right ribs or in the upper abdomen

๐ Nausea or vomiting later in pregnancy

๐ Sudden weight gain caused by fluid retention

Severe pre-eclampsia can lead to seizures, stroke, organ damage, placental complications, premature delivery, or life-threatening illness.

Swelling of the feet alone is common during pregnancy and does not confirm pre-eclampsia, but sudden or severe swelling should be assessed.

6. Oligohydramnios

Oligohydramnios is a condition in which the amount of amniotic fluid surrounding the baby is lower than expected for the stage of pregnancy.

Doctors usually diagnose it through ultrasound measurements rather than fluid volume alone.

Possible causes include:

๐ Leakage or rupture of the amniotic membranes

๐ Placental insufficiency

๐ High blood pressure during pregnancy

๐ Foetal kidney or urinary tract abnormalities

๐ Pregnancy continuing beyond the expected delivery date

๐ Certain medicines

Insufficient amniotic fluid may increase the risk of:

๐ Restricted foetal growth

๐ Compression of the umbilical cord

๐ Abnormal foetal heart-rate patterns

๐ Problems with lung development when the condition occurs early and is severe

๐ The need for early delivery in selected cases

Management depends on the gestational age, underlying cause, fluid level, and condition of the baby.

Depression During Pregnancy

Depression during pregnancy is another important condition that should not be overlooked.

Hormonal changes, physical discomfort, morning sickness, family or financial concerns, an unplanned pregnancy, previous mental health conditions, and anxiety about childbirth or parenting may all contribute.

Possible symptoms include:

๐ Persistent sadness or emptiness

๐ Loss of interest in usual activities

๐ Excessive guilt or hopelessness

๐ Severe anxiety

๐ Difficulty sleeping or sleeping excessively

๐ Changes in appetite

๐ Difficulty concentrating

๐ Withdrawing from family and friends

๐ Thoughts of self-harm or suicide

Support from partners, family members, and healthcare professionals is important. Relaxation techniques, suitable physical activity, counselling, psychological therapy, and medication when clinically appropriate may all form part of treatment.

Meditation may help some women manage stress, but it should not replace professional care when symptoms are persistent or severe.

Who May Need Closer Pregnancy Monitoring?

Closer antenatal supervision may be recommended for women who:

๐ Are younger than 15 or older than 35-40 years

๐ Have previously experienced miscarriage, stillbirth, or premature delivery

๐ Have diabetes, high blood pressure, heart disease, kidney disease, or an autoimmune condition

๐ Are carrying twins or multiple babies

๐ Have previously undergone uterine surgery

๐ Have significant anaemia or other chronic illness

๐ Develop vaginal bleeding, severe pain, or abnormal ultrasound findings

Warning Signs Requiring Immediate Medical Care

Pregnant women should seek urgent medical attention for:

๐ Heavy vaginal bleeding

๐ Severe or persistent abdominal pain

๐ Fainting or severe dizziness

๐ Severe headache or blurred vision

๐ Sudden swelling of the face or hands

๐ Difficulty breathing or chest pain

๐ High fever

๐ Fluid leaking from the vagina

๐ Reduced or absent foetal movement after movement has normally become established

๐ Seizures or loss of consciousness

Regular antenatal care, appropriate screening, and prompt evaluation of unusual symptoms can reduce the risk of serious complications and improve outcomes for both mother and baby.
