Missed abortion is a type of miscarriage that occurs when the fetus has stopped developing or has died, but the body does not recognize the pregnancy loss or expel the pregnancy tissue. The term "missed abortion" is used to describe an in utero death of the embryo or fetus before the 20th week of gestation with retained conception products. Some key points about missed abortion are:

• It is also known as a missed miscarriage or a silent miscarriage.
• It is not an elective abortion.
• It is difficult to diagnose because it doesnt cause symptoms of bleeding and cramps that occur in other types of miscarriages.
• Signs of missed abortion may include brownish or red vaginal discharge, lessening or disappearing early pregnancy symptoms, and an underdeveloped fetus on ultrasound.
• Chromosomal abnormalities in the fetus are the most common cause of missed miscarriages.
• Medical, surgical, and expectant management are all options for managing missed abortion.
• Risk factors for missed abortion may include age, BMI, and the difference between mean gestational sac diameter and crown-rump length.

If you suspect that you have missed abortion, it is important to seek medical attention. Your healthcare provider can diagnose the condition and recommend the appropriate treatment based on your individual situation.
