Pregnancy offers a window of opportunity to program the future health of both mothers and offspring. During gestation, women experience a series of physical and metabolic modifications and adaptations, which aim to protect the fetus development and are closely related to both pre-gestational nutritional status and gestational weight gain.

This article reviews maternal metabolic strategies for accommodating fetal nutrient requirements in normal pregnancy and in gestational diabetes mellitus GDM. Pregnancy is characterized by a progressive increase in nutrient-stimulated insulin responses despite an only minor deterioration in glucose tolerance, consistent with progressive insulin resistance. Metabolic adaptations do not fully compensate in GDM and glucose intolerance ensues. GDM may reflect a predisposition to type 2 diabetes or may be an extreme manifestation of metabolic alterations that normally occur in pregnancy. Commensurate with the increased rate of glucose appearance, an increased contribution of carbohydrate to oxidative metabolism has been observed in late pregnancy compared with pregravid states.

Glucose Metabolism in Pregnancy

Maternal lipids are strong determinants of fetal fat mass. Here we review the overall lipid metabolism in normal and gestational diabetes mellitus GDM pregnancies. During early pregnancy, the increase in maternal fat depots is facilitated by insulin, followed by increased adipose tissue breakdown and subsequent hypertriglyceridemia, mainly as a result of insulin resistance IR and estrogen effects. The response to diabetes is variable as a result of greater IR but decreased estrogen levels. The vast majority of fatty acids FAs in the maternal circulation are esterified and associated with lipoproteins. These are taken up by the placenta and hydrolyzed by lipases.

Metrics details. Maternal diet restriction might be associated with adverse maternal and perinatal outcomes due to metabolic changes. This study aimed to investigate the prevalence of changes in glucose levels due to Ramadan fasting in Emirati pregnant women. The two groups of pregnant women had similar physiological parameters. Caregivers need to consider the 1-hour postprandial glucose level response after fasting in Muslim pregnant women. Research of an interventional design is required to determine remedial actions for this issue.

Infant macrosomia is a classic feature of a gestational diabetes mellitus GDM pregnancy and is associated with increased risk of adult obesity and type II diabetes mellitus, however mechanisms linking GDM and later disease remain poorly understood. We examined the effects of GDM on maternal insulin resistance, fetal growth, and postnatal development of hepatic insulin resistance.

Determinants of Maternal Insulin Resistance during Pregnancy: An Updated Overview

Gestational diabetes is a risk factor for perinatal complications; include shoulder dystocia, birth injuries such as bone fractures and nerve palsies. It is associated with later development of type 2 diabetes, the risk of macrosomia and other long-term health effects of infants born to diabetic mothers. The study assesses placental peptides and maternal factors as potential predictors of gestational diabetes among pregnant women. A total of pregnant women were recruited for the study, pregnant women without pre gestational diabetes including 50 women with low risk factors of diabetes as controls and 50 other pregnant women with pregestational diabetes as control. Glycated haemoglobin was assessed using the Cation Exchange resin method.

Principles of Perinatal-Neonatal Metabolism pp Cite as. Pregnancy is a state of ever-increasing fetal demand for fuel. This demand is met through increased caloric intake, hyperinsulinemia, insulin resistance, and maternal pancreatic islet hypertrophy. In addition, fasting in the pregnant state results in maternal hypoglycemia, elevated plasma lipid concentrations, and hypoaminoacidemia. These maternal adaptive changes serve the unique purpose of self-preservation, with an attempt to use lipid as an alternative fuel in the face of the uninterrupted siphoning of glucose and amino acids to the fetus. The regulation of maternal glucose homeostasis, nutrient flow, and hormonal regulation of maternal and fetal pancreatic function is the subject of this chapter. This discussion of glucose metabolism in pregnancy is divided into three time periods: the first, second, and third trimesters, and a discussion of the postpartum changes is included.

Insulin resistance changes over time during pregnancy, and in the last half of the pregnancy, insulin resistance increases considerably and can become severe, especially in women with gestational diabetes and type 2 diabetes. Numerous factors such as placental hormones, obesity, inactivity, an unhealthy diet, and genetic and epigenetic contributions influence insulin resistance in pregnancy, but the causal mechanisms are complex and still not completely elucidated. In this review, we strive to give an overview of the many components that have been ascribed to contribute to the insulin resistance in pregnancy. Knowledge about the causes and consequences of insulin resistance is of extreme importance in order to establish the best possible treatment during pregnancy as severe insulin resistance can result in metabolic dysfunction in both mother and offspring on a short as well as long-term basis. The physiology of insulin resistance during pregnancy is fascinating, from an evolutionary point of view designed to limit maternal glucose utilization and thereby shunt an adequate amount of supply to the growing fetus, which requires most of its energy source as glucose.

Diet restriction in Ramadan and the effect of fasting on glucose levels in pregnancy

Pregnancy offers a window of opportunity to program the future health of both mothers and offspring. During gestation, women experience a series of physical and metabolic modifications and adaptations, which aim to protect the fetus development and are closely related to both pre-gestational nutritional status and gestational weight gain. Moreover, pre-gestational obesity represents a challenge of treatment, and nowadays there are new evidence as regard its management, especially the adequate weight gain.

Тот огляделся вокруг, указательным пальцем разгладил усы и наконец заговорил: - Что вам нужно? - Он произносил английские слова немного в нос. - Сэр, - начал Беккер чуть громче, словно обращаясь к глуховатому человеку, - я хотел бы задать вам несколько вопросов. Старик посмотрел на него с явным недоумением. - У вас какие-то проблемы.

 Сьюзан. По ее щеке скатилась слеза. - Что с тобой? - в голосе Стратмора слышалась мольба.

Мы ищем различие, выражаемое простым числом. Через несколько секунд всем стало ясно, что эта затея бессмысленна. Числа были огромными, в ряде случаев не совпадали единицы измерения.

Он должен был бы удариться в панику, но этого не произошло: он точно знал, куда держит путь. Свернув влево, на Менендес-пелайо, он прибавил газу. Мотоцикл пересек крохотный парк и выкатил на булыжную мостовую Матеус-Гаго - узенькую улицу с односторонним движением, ведущую к порталу Баррио - Санта-Крус. Еще чуть-чуть, подумал. Такси следовало за Беккером, с ревом сокращая скорость. Свернув, оно промчалось через ворота Санта-Крус, обломав в узком проезде боковое зеркало. Беккер знал, что он выиграл.


In fact, the consequences to the fetus of uncontrolled maternal diabetes are so severe that successful termination of a diabetic pregnancy in the pre-insulin era.


Review ARTICLE

Сьюзан смотрела на эти буквы, и они расплывались перед ее слезящимися глазами. Под вертикальной панелью она заметила еще одну с пятью пустыми кнопками. Шифр из пяти букв, сказала она себе и сразу же поняла, каковы ее шансы его угадать: двадцать шесть в пятой степени, 11 881 376 вариантов. По одной секунде на вариант - получается девятнадцать недель… Когда она, задыхаясь от дыма, лежала на полу у дверцы лифта, ей вдруг вспомнились страстные слова коммандера: Я люблю тебя, Сьюзан. Я любил тебя. Сьюзан.

Сьюзан прошла мимо него с поразившим его выражением человека, потрясенного предательством. Коммандер не сказал ни слова и, медленно наклонившись, поднял пейджер. Новых сообщений не. Сьюзан прочитала их .
