In maternal diabetes, 90% of pregnancy losses happen in the first trimester due to oxidative stress. Diabetic embryopathy abortions in the second-trimester are most likely due to severe birth defect , maternal metabolic derangement, placental insufficiency and fetal hypoxia due to membrane rupture.
Gestational diabetes is a condition in which a woman without diabetes develops high blood sugar levels during pregnancy. [2] Gestational diabetes generally results in few symptoms; [2] however, obesity increases the rate of pre-eclampsia, cesarean sections, and embryo macrosomia, as well as gestational diabetes. [2]
[36] [34] During pregnancy the placenta concentrates B 12, so that newborn infants have a higher serum concentration than their mothers. [33] What the mother-to-be consumes during the pregnancy is more important than her liver tissue stores, as it is recently absorbed vitamin content that more effectively reaches the placenta.
Miscarriage is the loss of a pregnancy prior to 20 weeks. [43] [44] In the UK, miscarriage is defined as the loss of a pregnancy during the first 23 weeks. [45] Comprehensive support, consists of the consultation of the genomics as well as the provision of the medical or surgical operations required. The psychological relevance of family ...
Pre-gestational diabetes can be classified as Type 1 or Type 2 depending on the physiological mechanism. Type 1 diabetes mellitus is an autoimmune disorder leading to destruction of insulin-producing cell in the pancreas; type 2 diabetes mellitus is associated with obesity and results from a combination of insulin resistance and insufficient insulin production.
Intrauterine hypoxia can be attributed to maternal, placental, or fetal conditions. [12] Kingdom and Kaufmann classifies three categories for the origin of fetal hypoxia: 1) pre-placental (both mother and fetus are hypoxic), 2) utero-placental (mother is normal but placenta and fetus is hypoxic), 3) post-placental (only fetus is hypoxic).
Progesterone causes many changes to the genitourinary system. A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increase blood volume and vasculature. Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureter, which are normal. [33]
Screening for diabetes during pregnancy continues to require fasting and glucose-tolerance measurements for gestational diabetes at 24 to 28 weeks gestation, although glycated hemoglobin may be used for screening at the first prenatal visit. [37]
