The Effect of Pregnancy in the Haemoglobin Concentration of Pregnant Women
Background: Anemia is a major health problem that affects 25% to 50% of the population of the world and approximately 50% of pregnant women. Hence; the present study was conducted with the aim of assessing the Effect of Pregnancy in the Haemoglobin Concentration of Pregnant Women.
Materials & methods: A total of 200 pregnant subjects were enrolled. Data were collected using interview technique, reviewing the medical records, and using laboratory samples collection. Blood samples were obtained from the study participants before pregnancy, during the first trimester, during the second trimester, during the third trimester, during the onset of labor, after the third stage of labor, and at the 6-week postpartum period. Haemoglobin concentration was measured at different time intervals. A master chart was prepared and all the details were recorded and analysed.
Results: Out of these patients, 61.5 percent of the patients were of primigravida while the remaining were of multigravida. Mean Hb levels before pregnancy, at First trimester, at Second trimester, at Third trimester, Onset of labor, After third stage of labor and After 6 weeks was 13.2, 11.5, 11.1, 10.3, 10.1, 10.2, 9.5 g/dL respectively.
Conclusion: From the above results, the authors conclude that Pregnancy significantly depletes the hemoglobin concentration of the women.
