Pregnancy is a beautiful journey, but it’s also a very delicate one. During those nine months, a lot is happening inside the womb — and a baby’s future health depends heavily on both genetic and environmental factors.
While many women have healthy pregnancies and deliveries, some unfortunately give birth to babies with physical, mental, or developmental disabilities. In most cases, it’s not the mother’s fault, but rather the result of complex medical, genetic, or lifestyle-related issues.
Here are 4 common reasons why some babies are born with disabilities:
1. Genetic Disorders and Family History
Sometimes, disabilities are caused by genetic conditions passed down through families. These conditions happen when there’s an abnormality in the baby’s genes or chromosomes. Examples include Down syndrome, muscular dystrophy, and sickle cell disease.
Why it matters: Parents don’t always know they’re carriers of certain genes. That’s why genetic testing and early prenatal screening can help detect some conditions before birth and guide decisions later on.
2. Infections During Pregnancy
Certain infections during pregnancy can harm the development of the baby. These include rubella (German measles), toxoplasmosis, Zika virus, syphilis, and cytomegalovirus (CMV). Some of these infections, if caught early enough, can be managed — but if left untreated, they can lead to birth defects or hearing, vision, and brain development issues.
Regular prenatal checkups and early diagnosis help protect the baby from harmful infections. It’s important to avoid exposure to risky environments during pregnancy and always speak with a doctor if unusual symptoms appear.
3. Exposure to Harmful Substances
The baby’s development is affected by what the mother consumes or is exposed to. Taking certain medications without medical supervision, drinking alcohol, smoking, or using recreational drugs during pregnancy can interfere with brain and body development in the womb. This may result in conditions such as fetal alcohol syndrome or other physical and mental disabilities.
Many women may not know they’re pregnant for the first few weeks, which is one of the most critical stages. That’s why it’s important to be mindful of what’s going into your body if there’s a chance you could be pregnant — or when actively trying to conceive.
4. Poor Nutrition and Lack of Folic Acid
The baby gets all its nutrients from the mother, especially in the early stages. A lack of essential vitamins — especially folic acid — increases the risk of birth defects in the brain and spine, particularly neural tube defects like spina bifida.
Eating a balanced diet, taking prenatal supplements, and starting folic acid even before pregnancy can help prevent many of these issues. Doctors recommend at least 400 to 600 micrograms of folic acid daily during pregnancy.
