What is a common cause of uterine bleeding in the first trimester?

1. Placenta previa

2. Threatening abortion

3. Gestational diabetes

4. Placental abruption

The correct answer is: Threatening abortion

In the context of uterine bleeding during the first trimester, a threatening abortion, often referred to as a threatened miscarriage, is a common cause. This condition typically presents with vaginal bleeding and sometimes cramping, indicating a potential risk to the pregnancy. It occurs when there are signs that a miscarriage may happen but has not yet been confirmed. In many cases, the pregnancy may still continue, and further monitoring is usually required. Placenta previa and placental abruption, while they can cause bleeding in pregnancy, are generally more associated with later trimesters. Gestational diabetes does not typically cause uterine bleeding; instead, it is a condition related to glucose metabolism that can develop during pregnancy. Thus, the identification of a threatening abortion as a reason for bleeding makes this option the correct choice in the context of early pregnancy concerns. Understanding this can help in recognizing the signs and symptoms that warrant medical evaluation in pregnant patients.
