Definition

Pregnancy is the condition of carrying one or more embryos or fetuses in the uterus. It typically lasts around 40 weeks from the last menstrual period to childbirth.

5 Must Know Facts For Your Next Test

1. During pregnancy, the immune system undergoes changes to tolerate the fetus, which can impact susceptibility to infections.
2. Pregnant women are at higher risk for severe respiratory infections such as influenza and COVID-19 due to altered immune responses.
3. Urinary tract infections (UTIs) are common during pregnancy because of hormonal and anatomical changes in the urogenital tract.
4. Certain fungal infections, like candidiasis, can be more prevalent during pregnancy due to changes in vaginal microbiota and immune function.
5. Parasitic infections such as toxoplasmosis can pose significant risks during pregnancy, potentially leading to severe complications for both mother and fetus.
