Blighted ovum is a condition where a woman feels pregnant but there is no baby in the womb. A woman who experiences it also feels pregnancy symptoms such as menstrual delay, nausea and vomiting in early pregnancy ( morning sickness ), hardened breasts, and abdominal enlargement. Even during pregnancy tests both test packs and laboratory results are positive.
At the time of conception, mature eggs (ovum) meet sperm. However, due to various factors, the fertilized egg sperm cannot develop fully, and only a fluid-filled placenta is formed. Nevertheless the placenta remains embedded in the uterus. The placenta produces the hormone HCG ( human chorionic gonadotropin ) where this hormone signals the ovaries and brain as a notice that there are already conception results in the uterus. The HCG hormone which causes the appearance of pregnancy symptoms such as nausea, vomiting, cravings and causes the pregnancy test to be positive. Because pregnancy tests both test packs and laboratories generally measure levels of the hormone HCG ( human chorionic gonadotropin ) which is often referred to as a pregnancy hormone.
Until now there is no way to detect early blighted ovum pregnancy. A new woman can be indicated to have blighted ovum if she has done a transvaginal ultrasound examination. But this action can only be done during pregnancy entering the age of 6-7 weeks. Because at that time the diameter of the pregnancy sac was greater than 16 millimeters so that it could be seen more clearly. From there it will also appear, there is a pregnancy sac that is empty and does not contain the fetus.
Because the symptoms are not specific, blighted ovum is usually found only after a spontaneous miscarriage will occur where bleeding complaints occur. In addition to blighted ovum, an enlarged abdomen such as pregnancy, can be caused by pregnant wine (hydatidiform mole), uterine tumor or intestinal disease.
About 60% of blighted ovum is caused by chromosomal abnormalities in the process of fertilizing eggs and sperm. TORCH infection, rubella and streptococci, uncontrolled diabetes (diabetes mellitus), low levels of beta HCG and immunological factors such as the presence of antibodies to the fetus can also cause blighted ovum. The risk also increases if the age of the husband or wife gets older because the quality of sperm or ovum drops.
If you have been diagnosed with blighted ovum, then the next action is to remove the conception from the uterus (curettage). The results of curettage will be analyzed to determine what causes blighted ovum and then overcome the cause. If due to infection it can be treated so that this incident does not recur. If the cause is antibodies, an immunotherapy program can be done so that later you can get real pregnancy.
To prevent the occurrence of blighted ovum, it can be done several precautions such as TORCH examination, rubella immunization in women who want to get pregnant, if they suffer from cured disease first, controlled their blood sugar, perform chromosomal examinations, especially if over 35 years of age, stop smoking for quality sperm / ovum is good, checking for a routine pregnancy and getting used to a healthy lifestyle.
