Wel rinku,
Eclampsia, a life-threatening complicatio of pregnancy, results when a pregnant woman previously diagnosed with preeclampsia (high blood pressure and protein in the urine) develops seizures or coma. In some cases, seizures or coma may be the first recognizable sign that a pregnant woman has preeclampsia. Key warning signs of eclampsia in a woman diagnosed with preeclampsia may be severe headaches, blurred or double vision, or seeing spots. Toxemia is a common name used to describe preeclampsia and eclampsia.
There has never been any evidence suggesting an orderly progression of disease beginning with mild preeclampsia progressing to severe preeclampsia and then on to eclampsia. The disease process can begin mild and stay mild, or can be initially diagnosed as eclampsia without prior warning.
Approximately 5-7% of all pregnancies are complicated by preeclampsia.
Preeclampsia usually occurs in a woman's first pregnancy but may occur for the first time in a subsequent pregnancy.
Less than one in 100 women with preeclampsia will develop eclampsia or (convulsions or seizures) or coma.
Up to 20% of all pregnancies are complicated by high blood pressure. Complications resulting from high blood pressure, preeclampsia, and eclampsia may account for up to 20% of all deaths that occur in pregnant women.
Eclampsia Causes
No one knows what exactly causes preeclampsia or eclampsia.
Since we don't know what causes preeclampsia or eclampsia, we don't have any effective tests to predict when preeclampsia or eclampsia will occur, or treatments to prevent preeclampsia or eclampsia from occurring (or recurring).
Preeclampsia usually occurs with first pregnancies. However, preeclampsia may be seen with twins (or multiple pregnancies), in women older than 35 years, in women with high blood pressure before pregnancy, in women with diabetes, and in women with other medical problems (such as connective tissue disease and kidney disease).
For unknown reasons, African American women are more likely to develop eclampsia and preeclampsia than white women.
Preeclampsia may run in families, although the reason for this is unknown.
Preeclampsia is also associated with problems with the placenta, such as too much placenta, too little placenta, or how the placenta attaches to the wall of the uterus. Preeclampsia is also associated with hydatidiform mole pregnancies, in which no normal placenta and no normal baby are present.
There is nothing that any woman can do to prevent preeclampsia or eclampsia from occurring. Therefore, it is both unhealthy and not helpful to assign blame and to review and rehash events that occurred either just prior to pregnancy or during early pregnancy that may have contributed to the development of preeclampsia.
