Many new mothers face real struggle losing the weight gained during pregnancy. But reducing only 4 kg during pregnancies may help many women diagnosed with a dangerous complication (Preeclampsia) for the duration of the first pregnancy to keep away from a reappearance the second time around.
Preeclampsia, characterized by high blood pressure, protein in the urine and puffiness during pregnancy can have an effect on liver, kidneys and the body's blood clotting system. Researchers don't know why several women develop preeclampsia and others don't but being overweight appears to be a risk factor.
An earlier American study showed that pre-pregnancy weight is one of the strongest risk factors for reappearance and losing even a small amount of weight offers health benefits, such as reduced risk of heart disease. To find out whether change in weight after first pregnancy affects risk of repeated preeclampsia, researcher studied 17,873 American women who gave birth two times between 1989 and 2005 and developed preeclampsia during the first pregnancy. The participants were divided into three groups: those who decreased their BMIs, those who maintained their BMIs and those who increased their BMIs between their first two pregnancies.
Before their second pregnancies, 1417 of the women had weighed less than before their first, 8,783 had remained the same, and 8,798 had weighed more. The women who maintained their weights were used as the control group.
It was found that about 16 percent of women developed preeclampsia during their second pregnancies. Of the women who had lost weight between pregnancies, 13 percent had a recurrence while 15 percent of women who maintained their weight and nearly 19 percent of those who gained weight had a recurrence. Small changes in maternal weight between pregnancies - as little as 4 kg for an average height overweight woman - significantly alter the risk of preeclampsia recurrence across all weight categories.
The result of this study recommend that if you are overweight and you lose weight, your rate of preeclampsia recurrence is as low as somebody in the normal weight group, and if you are overweight and gain weight, your rate is as high as someone in the obese category. Similarly, if normal weight people gain weight they have as high a risk as overweight people.
Few options survive for lowering a woman's risk of rising preeclampsia in her second pregnancy but this study shows that losing weight between pregnancies is the most reasonable measure to significantly lower this risk.
