Pregnant
Pregnancy is a period in a woman's life when she carries a developing offspring, known as an embryo or fetus, in her uterus. This condition usually lasts about 40 weeks, or slightly over 9 months, as measured from the last menstrual period to delivery. Pregnancy is divided into three trimesters, each lasting about three months.
Signs and symptoms[edit | edit source]
The initial signs of pregnancy usually include missed periods, nausea, increased urination, and fatigue. Other symptoms may include tender breasts, increased appetite, and changes in taste. Pregnancy tests can confirm a pregnancy by detecting the presence of human chorionic gonadotropin (hCG).
Diagnosis[edit | edit source]
Pregnancy can be diagnosed using pregnancy tests that detect hCG, a hormone released by the placenta. These tests can be performed around the time of the missed menstrual period. Ultrasound imaging can also be used to confirm the presence of a developing fetus.
Physiology[edit | edit source]
During pregnancy, the woman's body undergoes many physiological changes, including cardiovascular, hematologic, metabolic, renal, and respiratory changes, to support the developing fetus and prepare the body for childbirth.
Complications[edit | edit source]
Complications of pregnancy may include disorders of high blood pressure, gestational diabetes, iron-deficiency anemia, and severe nausea and vomiting. In the ideal case, pregnancies are managed by a multidisciplinary team that includes an obstetrician, midwife, and doula.
Society and culture[edit | edit source]
Pregnancy is typically celebrated with baby showers and the taking of maternity photographs. Many countries have laws protecting pregnant women's rights.
