In obstetrics, G6P4+1 refers to a woman's obstetric history.
- G6: Gravida 6, which means the total number of pregnancies a woman has had, including the current pregnancy. - P4: Para 4, which means the total number of live births a woman has had. - +1: Refers to the number of pregnancies that ended in a miscarriage, abortion, or stillbirth before reaching viability (usually before 20 weeks gestation).
So, in this case, G6P4+1 would mean that the woman has been pregnant a total of 6 times, has given birth to 4 live babies, and has had 1 pregnancy that ended in a miscarriage, abortion, or stillbirth.
