SAB in pregnancy stands for Spontaneous Abortion, which is also known as a miscarriage. It refers to the loss of a pregnancy before the 20th week of gestation.
Here's a more detailed explanation:
-
Definition: Spontaneous abortion (SAB) is the termination of a pregnancy before the fetus is able to survive outside the womb.
-
Causes: There are many potential causes of SAB, including:
- Chromosomal abnormalities in the fetus.
- Hormonal imbalances in the mother.
- Uterine problems.
- Infections.
- Lifestyle factors.
-
Clinical Significance: The provided reference ("Spontaneous Abortion (SAB) of Clinical Intrauterine Pregnancy (IUP) Following in Vitro Fertilization (IVF) Is Not Correlated With Follicle Stimulating Hormone (FSH)") specifically looks at SAB in the context of pregnancies achieved through in vitro fertilization (IVF). The study suggests that FSH levels are not related to SAB.
-
Symptoms: Symptoms of a spontaneous abortion can include:
- Vaginal bleeding.
- Cramping.
- Passage of tissue.
-
Diagnosis: A doctor can diagnose a spontaneous abortion through a physical exam, ultrasound, and blood tests.
-
Treatment: Treatment depends on how far along the pregnancy was and whether or not all of the tissue has passed from the uterus. Treatment options may include:
- Expectant management (waiting for the tissue to pass naturally).
- Medication to help the tissue pass.
- Surgical procedure (dilation and curettage, or D&C) to remove the tissue.
