Meaning of Birth Defects

Birth defects, medically which are also coined as “congenital anomalies” or “congenital malformation” are defined as any physical abnormality that occurs during the time of the pregnancy and before a baby is born and is present at the time of the birth as well. The most common defect in children is heredity birth defects. 


Heredity birth defects are the result of a genetic mutation. These mutations will affect the appearance or functioning of a child in some way. These defects are usually due to the usage of alcohol and other drugs during pregnancy. However, there can also be many other causes, discussed in detail in the article.

Types of Birth Defects

A birth defect can be internally (inside a body), visibly (like a missing arm or a birthmark), or chemically abnormal (a defect in a chemical reaction that results in developmental delay) in a newborn baby’s body. There can be numerous birth defects. 

  • Congenital Heart Disease (CHD): This birth defect in kids is termed an umbrella defect as it is used to represent any heart issue that directly or indirectly affects the working of other organs of the body. 

  • Down Syndrome: The extra chromosome causes a developmental delay in the child; the eyes are slanted downwards, the muscles are quite weak, and there are birth defects in the heart and intestines. 

  • Ventricular Septal Defect: It is popularly known as a hole in the heart and is the most common heart condition or defect. 

  • Clubfoot: It is an abnormality found in the feet. In this, the foot is found to be turned inwardly. 

  • Cleft Lip (a gap in the upper lip) and Cleft Palate (a hole in the roof of the mouth): Cleft lip birth defects occur when both lips are not joined entirely. Cleft palate, as a birth defect in kids, occurs when the lip cannot join in the uterus only. 

  • Limb Defects: This is the second most common defect during birth after clubfoot. A limb defect is an abnormality in the arms or the legs. This birth defect can be found in 1 in every 1,943 births.

The above-mentioned birth defects have known to affect around 10,000 babies each year.


Causes of Birth Defects

There can be different causes and it depends on the type of birth defect. For most birth defects in kids, the causes are unknown as we all think that there could have been multiple causes.

  • Exposure to Harmful Substances: For example, radiation. Most pregnant women when exposed to high radiation, may increase their chance of birth defects in kids. 

  • Exposure to Drugs: If a mother before or during the pregnancy has been taking drugs, whether, in large or even small quantities, it can directly affect the health of the child.

  • High Intake of Alcohol: Another reason for defects is smoking and drinking alcohol in large quantities during pregnancy.

  • Nutrition: An expecting mother must have a balanced and nutritious diet. Not being able to feed the unborn baby with healthy food might lead to many complexities and sometimes defects during birth. 

  • Genetic Factors: Sometimes genetic conditions play a vital role in the health of the child. If someone in your family tree has a birth defect, your child might likely display the same disorder. 

  • Infections: If an expecting mother had an infection like chickenpox, rubella, syphilis, etc., during pregnancy, then there is a slight chance of the baby getting infected too.


Diagnosis of Birth Defects

Certain defects can be diagnosed before birth to mentally prepare the parents and so that some measures can be taken to rectify them further. There can be different diagnoses and it depends on the type of birth defect. The types are as follows.

  • Prenatal ultrasounds

  • Genetic screenings

  • Newborn exam

  • Prenatal/Postnatal MRI 


Precautions to be Taken to avoid Birth Defects

To make sure that a mother has a healthy pregnancy, the parents should follow some important points:

  • Avoid alcohol at any cost.

  • Completely quit drugs and smoking, if taken earlier.

  • Must at any cost visit the doctor regularly.

  • Should take all the vitamins and folic acid prescribed by the doctor.

  • Should eat a healthy diet at all times to pass on the required nutrients to the child.
