Frequent Abortion

What are the causes of recurrent abortion
 
Recurrent pregnancy loss is defined as loss of two or more consecutive pregnancies. There are many causes for this and it is recommended that any couple that has lost three consecutive pregnancies must be fully evaluated. Despite intensive evaluation, no cause may be found in some couples. A major cause of pregnancy loss is decreased maternal immune tolerance to the foetus. During pregnancy, the mother’s immune system is suppressed in order that it does not attack the foetus. In many women it is seen that this suppression may not occur due to many reasons. APLA, and Anti thyroid antibodies are two major reasons for this. In addition chromosomal anomalies in the parents or the foetus can cause loss of pregnancy. Endocrine disorders like hypothyroidism and diabetes mellitus, PCOS, Obesity, Thrombophilic disorders, hormonal factors, infections in the uterus, and structural abnormalities in the uterus can all lead to loss of pregnancy. Lifestyle factors like alcohol intake, smoking etc can also affect pregnancy. A complete evaluation will be required to find out the cause and to offer treatment.
