Pregnancy is often painted as a glowing and joyful time — but behind the baby bump and excitement, many expectant mothers in South Africa are quietly facing health risks that go unnoticed, undiagnosed, and untreated.
“While most women know the basics of pregnancy care, there are lesser-known risks that can have serious consequences for both mom and baby,” says Sr Londe, an independent midwife and Vital Baby’s trusted advisor, working with families across South Africa.
“And too often, they’re only picked up when things go wrong.”
From vitamin deficiencies to high blood pressure and undetected anaemia, these “silent risks” are more common than you might think — and they’re especially relevant in the South African context.
1. Vitamin D Deficiency – The Hidden Threat
You’d think a sunny country like South Africa wouldn’t have to worry about Vitamin D levels — but studies show that up to 80% of South African women are deficient during pregnancy, especially those with darker skin tones or limited sun exposure.
Vitamin D is essential for calcium absorption and foetal bone development. Low levels have been linked to gestational diabetes, low birth weight, and even developmental delays after birth.
Most women are normally unaware that they’re deficient because symptoms like fatigue and mood swings are brushed off as ‘normal pregnancy symptoms’, but it’s worth testing and supplementing if necessary.
2. Pregnancy Hypertension – Not Just a Late-Pregnancy Problem
High blood pressure in pregnancy (also called gestational hypertension or pre-eclampsia) has become a growing concern, especially in women over 35, first-time moms, or those with underlying conditions.
In South Africa, pre-eclampsia is one of the leading causes of maternal mortality, according to data from the Department of Health.
Symptoms can include swelling, headaches, or visual disturbances — but often, there are no early warning signs at all. That’s why regular blood pressure checks at every antenatal visit are so critical.
“Hypertension doesn’t just affect the mother,” warns Sr Londe. “It can limit blood flow to the baby, leading to premature birth or growth issues.”
3. Anaemia – Common, but Often Ignored
Iron-deficiency anaemia is one of the most prevalent nutritional conditions in pregnant South African women — yet it’s often overlooked as just being “tired” or “run-down.”
Anaemia can increase the risk of preterm labour, low birth weight, and even postnatal depression.
“Many women assume exhaustion is just part of pregnancy,” says Sr Londe, “but if you’re struggling to get through the day, can’t catch your breath, or feel dizzy often — it’s worth checking your iron levels.”
While some of these risks may sound worrying, the good news is they are easily manageable with the right support. The key is awareness, routine checks, and not brushing off how you feel.
- Get regular antenatal care. Attend every check-up, even if you feel fine. Many of these risks are picked up in routine screenings.
- Ask about blood tests. Vitamin D and iron levels aren’t always tested automatically. Ask your healthcare provider if it’s worth checking.
- Speak up about symptoms. Fatigue, headaches, mood changes — don’t dismiss them. If something feels off, say so.
- Get some safe sunshine. If you’re indoors a lot, especially during winter or if you’re wearing sunscreen daily, try to get 10–20 minutes of safe sun exposure in the early mornings and late afternoons for natural Vitamin D.
Pregnancy isn’t just about baby scans and cravings — it’s also a time of massive change for a woman’s body. And while many risks fly under the radar, they don’t have to be scary.
“When moms are informed, they’re empowered,” says Sr Londe. “A healthy pregnancy starts with understanding your body, trusting your instincts, and never being afraid to ask questions.”
