A birth defect is a difference in how a child’s body develops. These kinds of defects can impact their health, their ability to thrive, and their learning. Most birth defects are not preventable, but they can be treated or managed in most cases. Maintaining good health with birth defects is increasingly manageable due to advances in medical care related to these conditions.
Not all birth defects are detectable at birth, and not all of them are visible. Some patients do not develop symptoms of birth defects until they are teenagers or even adults. Some birth defects are quite severe and require surgeries and other interventions right away after birth. The symptoms of these conditions can vary widely depending on which kind of defect is present at birth.
Symptoms related to birth defects can range widely. They might include physical imperfections that are visible to the eye, problems with nutrition or feeding, or growth abnormalities that impact a child’s ability to thrive or to learn. Organ health might be impacted as well. Birth defects are very common, and there are many people who live into adulthood with a birth defect that is medically managed. Some birth defects impact people throughout their entire lives without being visible to anyone else.
Genetic changes can cause birth defects, but so can exposure to substances or chemicals before a baby is born. These genetic changes can also be caused by exposure to medications that the mother took during pregnancy. Additionally, they can also be the result of complications related to the pregnancy itself.
There are two major stages of development for foetuses while they are in the womb. The embryo stage lasts until week 10 after conception. This is the time when the foetus is the most vulnerable to genetic changes related to medications, chemicals, or pregnancy complications. That does not mean that these factors cannot impact foetal health in the second stage of a pregnancy, however.
Risk factors for genetic changes that cause birth defects are numerous and varied, but in general, mothers are told to avoid the use of alcohol, caffeine, and various medications during their pregnancy. Chromosomal changes can also lead to birth defects, and those who have a family history of certain genetic conditions will increase the risk that their child will be born with the same genetic mutations or changes.
An additional factor related to birth defects is an injury to the mother during pregnancy or a health condition that causes complications during the pregnancy. These conditions are usually unavoidable. Those who are pregnant should make sure to seek medical care as soon as possible for illnesses or injuries during their pregnancy.
Diagnosis of birth defects can vary based on the kind of birth defect that a child has. Some birth defects are present at birth, and diagnosis can be completed while the child is still in the hospital after birth. Other defects show up during health screenings later in life or when the child begins to present symptoms that could be related to a birth defect.
Blood tests, physical examinations, and imaging tests can all reveal birth defects in children and adults of any age. For mothers who submit to prenatal screenings, birth defects might be diagnosed before the child is even born.
Treatment of birth defects can vary greatly depending on the condition or defect that the patient is diagnosed with. Surgery might be necessary to help correct a physical limitation or to improve organ function. Medications can support healthy organ function and reduce symptoms as well. Supportive devices like wheelchairs, glasses, braces, and other items might also be of great assistance to these patients.
Developmental challenges can be addressed with physical therapy or mental health care. There are also sometimes school programs that are designed for those who suffer from birth defects to allow them to learn in a way that is designed for their unique needs.
Prevention of these kinds of defects is not usually possible. If genetic testing is done before someone chooses to get pregnant, a genetic counsellor can advise about the possibility that a child will suffer from genetic mutations that can be transferred from parents to their children. If the genetic defects show up during testing before the child is born, specialists can advise about any treatments that might be possible before the child is born.
