What is Miscarriage? Causes and Symptoms of Miscarriage

Miscarriage is a spontaneous abortion.

World Health Organization

(WHO) defines miscarriage as an unsurvivable state of a fetus or an embryo weighing less than 500 grams. Some women do not even discover they are pregnant, but they experience miscarriage. 15 percent of fertilized eggs are lost before they implant into the uterus wall.

Causes of Miscarriage:

Reasons for miscarriage are not always easy to determine. Common reasons for miscarriage is in the first trimester are:

Collagen:

Vascular diseases of collagen are problems in a person’s own immune system which attacks the organs. This is very dangerous either during or in between pregnancy. Antibody syndrome and Systemic lupus erythematous are the instances for collagen vascular diseases.

Diabetes:

This should be managed well during pregnancy. If diabetes is not controlled, risk of miscarriage increases, or the baby may develop major birth defects.

Chromosomal abnormalities:

The most common cause of early miscarriage is chromosomal abnormalities of the fetus, including blighted ovum.

Hormonal infection problems:

Hormonal problems like thyroid disease, poly-cystic ovary syndrome and Cushing’s Syndrome are risks for miscarriage and also cause birth defects to the baby.

Symptoms of miscarriage:

Vaginal or implantation bleeding and cramping

These are the most common signs of a spontaneous abortion. Bleeding and cramping can be mild, moderate or even severe. No particular pattern is known for the symptoms to last.

During early pregnancy, vaginal bleeding is referred to as:

Threatened abortion

The term “threatened abortion” is used because miscarriage is always preceded by vaginal bleeding during early pregnancy.
