Pregnancy
Pregnancy is the period during which a fetus develops in the uterus, typically lasting about 40 weeks. It is divided into three trimesters, each with its own physical and hormonal changes. While pregnancy is a natural process, it involves significant changes in the body and requires regular medical care to support the health of both the mother and baby.
Quick Facts
- Typically lasts about 40 weeks
- Divided into three trimesters
- Involves major hormonal and physical changes
- Requires regular prenatal care
- Each pregnancy experience can be different
- Home pregnancy tests are generally highly accurate when taken after a missed period, but early testing may lead to false negatives
Symptoms
Symptoms vary by stage but commonly include:
- Missed period
- Nausea or vomiting (morning sickness)
- Fatigue
Other symptoms may include breast tenderness, frequent urination, and mood changes. As pregnancy progresses, symptoms may include back pain, swelling, or shortness of breath.
Hormonal changes during pregnancy can increase the risk of yeast infections, which may cause itching, irritation, or discharge.
Some symptoms can overlap with hormonal conditions or digestive issues, especially early on.
Causes
Pregnancy occurs when a fertilized egg implants in the uterus and begins to develop. Hormonal changes support the growth and development of the fetus throughout the pregnancy.
While most pregnancies develop normally in the uterus, some eggs may implant outside the uterus, known as an ectopic pregnancy, which requires urgent medical attention.
Risk Factors
While pregnancy is a natural process, certain factors may increase risk for complications:
- Age under 20 or over 35
- Pre-existing medical conditions (such as diabetes or high blood pressure)
- Multiple pregnancy (twins or more)
- Lack of prenatal care
Treatments
Pregnancy care focuses on monitoring and supporting both maternal and fetal health.
This includes regular prenatal visits, screenings, and lifestyle guidance. Providers monitor growth, development, and any potential complications, such as preeclampsia.
In some cases, additional care or specialist referral may be needed for high-risk pregnancies.
When to Seek Care
Seek medical care right away if you experience severe abdominal pain, heavy bleeding, dizziness, or fainting, as these may be signs of complications such as ectopic pregnancy.
Pregnancy care is typically managed by an obstetrician-gynecologist (OB/GYN) or a midwife, but many patients also work with a primary care provider as part of their care team.
Regular prenatal visits are essential throughout pregnancy to monitor both maternal and fetal health.
