Ramadan Fasting and Maternal and Fetal Outcomes in Pregnant Women with Diabetes Mellitus: Literature Review.

ABSTRACT: There is an emerging Muslim and diabetic population in the United States and other Western countries and majority of pregnant women and patients with diabetes mellitus choose to fast during Ramadan. Fasting during Ramadan in pregnant women with diabetes may represent a 'perfect storm' of metabolic disturbances including hyperglycemia, hypoglycemia and ketosis. Recent continuous and flash glucose monitoring data suggests increased glycemic variability (fasting hypo- and post-Iftar hyperglycemia) in non-pregnant patients with diabetes during Ramadan. Only five small-scale studies, predominantly focused on women with gestational diabetes mellitus in Muslim-majority nations have explored maternal glycemic outcomes during Ramadan which is associated with lower mean blood glucose levels and higher frequency of fasting hypoglycemia. Data is limited however on important clinical outcomes such as symptomatic and serious hypoglycemia requiring hospitalization. Results have been conflicting regarding maternal Ramadan fasting and association with fetal outcomes in women without diabetes. Only one recently published study reported on perinatal outcomes in pregnant women with gestational diabetes which found no effect of Ramadan exposure on mean birthweight or macrosomia frequency but lower neonatal hypoglycemia prevalence, however a significant limitation was lack of documentation of maternal fasting status. At this stage, due to paucity of data, the current medical recommendation is against Ramadan fasting for pregnant Muslim women with diabetes. Large-scale population-based studies are warranted regarding maternal and fetal outcomes in pregnant fasting women with diabetes and such studies should characterize maternal fasting status and have meaningful and consistent clinical outcomes. High-quality data derived from these studies can assist clinicians in providing more evidence-based advice to safely navigate both mother and fetus through a potentially challenging pregnancy.

Project description:OBJECTIVES: To assess the maternal and fetal complications of pregnancy in mothers with gestational diabetes mellitus (GDM) compared with non-diabetic patients who delivered in the hospital during the study period. METHODS: The outcome of pregnancy in 220 Saudi patients with GDM identified from the delivery register/hospital database and matched for age, parity and body mass index with 220 non-diabetic controls were studied retrospectively from their case files. Patients with multiple pregnancies and abnormal presentation of the fetus were excluded from the study. RESULTS: The GDM patients were treated with either diet alone or with additional insulin in some patients who required better control of their blood sugar levels. Patients with GDM had a significantly higher incidence of pre-eclampsia (p<0.0001); preterm delivery (p=0.0226); induction of labor (p<0.0001); cesarean section (p=0.0019); higher mean birth weight (p<0.0001) of babies; large for gestational age infants (p=0.0011); macrosomia (p=0.0186); and admission to the neonatal intensive care unit (p=0.0003), compared with the control group. However, the rates of Apgar score <7 at 5 minutes, respiratory distress syndrome, neonatal hypoglycemia, hyperbilirubinemia and the need for phototherapy were similar in both groups of patients. Congenital anomalies and perinatal mortality rates were not significantly different in the two groups. CONCLUSION: GDM is recognized to be associated with increased rates of adverse maternal and neonatal outcomes, which are supported by the findings of this study. Even the mild form of GDM seems to have significant consequences for women and their offspring and is recommended to be aggressively treated. Evidence suggests that early diagnosis and strict control of blood sugar levels throughout the pregnancy can significantly reduce maternal and fetal complications. A multicenter, randomized controlled trial, based on universally accepted criteria for GDM screening test, standardized diagnostic OGTT and management of all patients with GDM versus the standard obstetric management of the control is warranted.

Project description:BackgroundThere are controversies over the effects of Ramadan fasting on pregnancy outcomes, and women's perspectives of fasting are diverse. This study aimed to assess the perspectives and pregnancy outcomes of maternal Ramadan fasting in the second trimester of pregnancy.MethodsA case-control study was conducted at Hawler Maternity Teaching Hospital of Erbil, Iraq from October 2017 to January 2018. Out of 301 participating women, 155 fasted during the second trimester of their current pregnancy, while the remaining 146 did not. Mothers were asked concerning their fasting behaviors and perception of fasting during pregnancy. The main outcomes of this study were gestational diabetes, preterm labour, preeclampsia, low birth weight, Apgar score, height, weight, and head circumference of the newborn.ResultsAbout 80% of the women in the fasting group fasted for 21-29 days during Ramadan, out of whom 38.7% completed fasting for the entire Ramadan period. The results revealed that the decision to fast during pregnancy was negatively associated with the mother's educational level and occupation. Weight gain during pregnancy in the fasting women was approximately 0.4 kg less than those who did not fast. The incidence of gestational diabetes was 2.6% in the fasting women, while it was 8.3% in the non-fasting mothers (P = 0.02). Regression analysis showed that women who did not fast during the second trimester of pregnancy were 1.51 times more likely to develop gestational diabetes [odd ratio (OR) 1.51; 95% confidence intervals (CI) 0.06, 0.74, P = 0.01]. It was also found that among the women in the fasting categories, those who fasted for 21-29 days during pregnancy had a lower risk of gestational diabetes compared to the other groups. More than half of the mothers in the fasting group (60%) perceived that fasting during pregnancy was compulsory for healthy and non-healthy women, comparing with those who did not fast.ConclusionIt was found that fasting during the second trimester of the pregnancy decreased the risk of gestational diabetes and excessive weight gain during pregnancy. Most of Iraqi women did not fully recognize their right to be exempted from fasting during pregnancy by the Islamic law.
