Fetal Health and Development
A normal pregnancy lasts nine months. Each three-month period of pregnancy is called a trimester. During each trimester, the fetus grows and develops. There are specific prenatal tests to monitor both the mother's health and fetal health during each trimester.
With modern technology, health professionals can
- Detect birth defects
- Identify problems that may affect childbirth
- Correct some kinds of fetal problems before the baby is born
- Fetal development
- Intrauterine growth restriction
Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs.
Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder.
You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.
There are three types of genetic disorders:
- Single-gene disorders, where a mutation affects one gene. Sickle cell anemia is an example.
- Chromosomal disorders, where chromosomes (or parts of chromosomes) are missing or changed. Chromosomes are the structures that hold our genes. Down syndrome is a chromosomal disorder.
- Complex disorders, where there are mutations in two or more genes. Often your lifestyle and environment also play a role. Colon cancer is an example.
Genetic tests on blood and other tissue can identify genetic disorders.

Health Problems in Pregnancy
Every pregnancy has some risk of problems. The causes can be conditions you already have or conditions you develop. They also include being pregnant with more than one baby, previous problem pregnancies, or being over age 35. They can affect your health and the health of your baby.
If you have a chronic condition, you should talk to your health care provider about how to minimize your risk before you get pregnant. Once you are pregnant, you may need a health care team to monitor your pregnancy. Examples of common conditions that can complicate a pregnancy include
- Heart disease
- High blood pressure
- Kidney problems
- Autoimmune disorders
- Sexually transmitted diseases
Other conditions that can make pregnancy risky can happen while you are pregnant - for example, gestational diabetes and Rh incompatibility. Good prenatal care can help detect and treat them.
Some discomforts, like nausea, back pain, and fatigue, are common during pregnancy. Sometimes it is hard to know what is normal. Call your doctor or midwife if something is bothering or worrying you.
