In the context of obstetrics, what does "G2P1001" signify about a patient's pregnancy history?

The notation "G2P1001" is a shorthand way to describe a woman's obstetric history. The first part, "G2," indicates that the patient has been pregnant twice. The "P" stands for "parity," which is further broken down into four numbers that provide specifics about the outcomes of those pregnancies.

In this case, "1001" means the following:

• The first digit (1) signifies that she has had one live birth.

• The second digit (0) indicates that she has had no pregnancies that resulted in premature births.

• The third digit (0) indicates that she has had no pregnancies that resulted in stillbirths.

• The fourth digit (1) signifies that she has had one pregnancy that ended in a miscarriage or abortion.

Putting this together, "G2P1001" correctly conveys that the patient has been pregnant twice, with one of those pregnancies resulting in a live birth. Therefore, the answer accurately reflects her pregnancy history.
