Pregnancy is an interesting time in women's lives, because it creates a new human being in the world. Although it is an interesting time for the mother, it could also be dangerous for the mother and baby. Pregnancy is divided into three trimesters and each trimester consists of three months. Complications occur throughout the trimester, but the third trimester has many complications. Complications in the third trimester are not only dangerous for the baby, but also for the mother. The Healthline editorial team said that several complications could occur during the third trimester. These complications are gestational diabetes, preeclampsia, preterm labor, premature rupture of membranes, problems with the placenta (previa and abruption), intrauterine growth restriction, post-term pregnancy and incorrect presentation. National DataAnn Abercrombie stated that “Every year in the United States, more than 500,000 babies are born prematurely and approximately 28,000 babies die before their first birthday” DataGestational diabetes is one of the complications that occur during the third trimester of pregnancy. It occurs at due to hormonal changes during pregnancy. Gestational diabetes may seem normal to most women as no symptoms are usually detected, but it could be dangerous for the fetus. It could cause macrosomia of the fetus which increases the chances of cesarean delivery and the risk of birth injuries. To prevent or reduce the risk of gestational diabetes, all pregnant women should be tested for gestational diabetes and the test result is positive, the mother will need to change her diet, exercise and use. insulin to normalize the glucose level. After having the baby, gestational diabetes usually r...... middle of paper ... ... rupture of membranes, abnormal CTG and prolonged labor clearly increase with age. 91.0% of women < 22 years and 84.5% of women > 32 years had a normal cephalic presentation. Regarding the mode of birth, 77.1% (< 22 years) and 53.1% (> 32 years) had a spontaneous birth, 14.5% (< 22 years) and 32.3 % (>32 years) have had a cesarean section. CONCLUSIONS: Older primiparas have a higher percentage of previous miscarriages and pregnancy terminations. They more commonly present pathological presentations and also more frequently require cesarean section. This means that a delayed first pregnancy - an increasingly common phenomenon in Germany - goes hand in hand with a greater likelihood of risks of childbirth, caesarean sections and peripartal interventions. Older primiparous women constitute a special risk group who may require a more intensive level of care.
