Children born to mothers with GDM are
up to 8-times more likely to develop
type 2 diabetes and obesity in their
teens or early adulthood.
Gestational diabetes also increases the risk for
type 2 diabetes in both mother and child

• AmP kinase activity.
• Insulin resistance.
• Insulin sensitivity.
In a recent study (2015) from Tamil Nadu,
globally recognised risk factors were not
significant:1
Although risk factors, to some extent, point to
additional risk among certain women, testing
according to risk factors would imply missing
out on 20-30% of hypoglycaemia in pregnancy

Screening and diagnostic testing for diabetes are performed because
identifying pregnant women with diabetes followed by
appropriate therapy can decrease feotal and maternal
morbidity, particularly macrosomia, shoulder dystocia,
and pre-eclampsia.
Universal testing for GDM is recommended1

Considering the high prevalence of GDM in India and the maternal &
foetal morbidity associated with untreated GDM all pregnant women
should be tested for GDM
Testing for GDM
Presentation title Date 28
• Testing for GDM is recommended twice during antenatal care (ANC)
• First testing done during first ANC contact
• Second testing done during 24-28 weeks of pregnancy if first test is
negative
• There should be at least 4 weeks gap between the two tests
• If a woman presents beyond 28 weeks of pregnancy only one test is
done
• If the test is positive at any point, protocol management should be followed

• Single step testing using 75 g Oral Glucose Tolerance Test (OGTT) and
measuring plasma glucose 2 hours after ingestion
• 75 g glucose to be given orally after dissolving in approximately 300 ml
water whether woman comes in fasting or non-fasting state
• Intake of solution has to be completed within 5 min.
• A plasma standardised glucometer should be used to evaluate blood glucose
2 hours after the oral glucose load
• If vomiting occurs within 30 min of oral glucose intake the test has to be
repeated the next day. If vomiting occurs after 30 minutes the test continues
• The threshold plasma glucose level of ≥140 mg/dL is taken as cut off for
diagnosis of GDM

• In most cases GDM can be managed
by Medical Nutrition Therapy (MNT)
• Principles of MNT
• MNT for GDM primarily involves a
carbohydrate controlled balanced meal
plan
• Nutrition assessment should be
individualised
• Maternal weight gain is the important
measure in follow up visits to determine
whether energy intake is adequate to
support fetal growth

• Carbohydrate foods are essential for a healthy diet for mother and baby.
• Once digested, carbohydrate foods are broken down to glucose, which goes into
the blood stream. The type, amount and frequency of carbohydrate intake has a
major influence on blood glucose readings.
• Large amounts of carbohydrate foods eaten at one time will lead to high blood
glucose level and should be avoided. It is better to spread carbohydrate foods
over 3 small meals and 2-3 snacks each day than taking 3 large meals.
• Complex carbohydrates (e.g. whole grain cereals) should be preferred over
simple carbohydrates like foods with lots of added sugar or honey or foods that
are made from refined white flour.
• Counting the number of carbohydrates serves that a mother eats during the
days will help her to eat the right amount.
Medical Nutrition Therapy (MNT)
Careful Selection of Carbohydrates

Mellitus, page 11.
• Saturated fat intake (ghee, butter, coconut oil,
palm oil, red meat, organ meat, full cream milk
etc.) should be less than 10% of total calories
and dietary cholesterol should be less than 300
mg/day. In obese and overweight patients, a
lower fat diet overall can help slow down the
rate of weight gain.
• Recommendations
• Use less fat in cooking and avoid frying of foods
• Using low-fat dairy products in place of whole milk
or full cream products
• Choose low-fat snack (e.g. fresh fruit) instead of
high-fat snacks (cakes, biscuits etc.)
• Use lean mean instead of read meat

For more details, see: Sample Diet Chart and Food
Exchange Chart for MNT in the National GDM Guidelines.
• When and What
• Insulin therapy is the accepted medical management of
pregnant women with GDM not controlled on MNT in 2 weeks
• The National Guidelines recommend the use of Human
Premix insulin 30/70. Oral tablets for diabetes treatment in
pregnancy are not to be given as they are not considered
safe.
• All pregnant women in whom MNT fails to achieve a 2 hr
PPPG <120 mg/dL are started on insulin, along with MNT
• In case of very high 2 hr PPPG:
• If 2 hr PPPG is >200 mg/dL at diagnosis, starting dose of
insulin should be 8 units pre-mixed insulin
• The dose to be adjusted on follow-up and at the same time
MNT has been followed. Frequency of monitoring to be
decided by the treating Physician/Gynaecologist/Medical
Officer.
• If the pregnant women requires more than 20 units
insulin/day, she should be referred to a higher healthcare
centre.

• Any pregnant woman on insulin can develop hypoglycaemia at any
time
• Hypoglycaemia is diagnosed when blood glucose level is < 70 mg/dl
• Important to recognise symptoms of hypoglycaemia & treat
immediately
• Early symptoms - Tremors of hands, sweating, palpitations, hunger, easy
fatigability, headache, mood changes, irritability, low attentiveness, tingling
sensation around the mouth/lips or any other abnormal feeling
• Severe - Confusion, abnormal behaviour or both, visual disturbances,
nervousness or anxiety, abnormal behaviour.

• Antenatal care of a pregnant woman with GDM should be provided by a gynaecologist, if available.
• If GDM is diagnosed before 20 weeks of pregnancy, a foetal anatomical survey by USG should be performed at
18-20 weeks.
• For all pregnancies with GDM, a foetal growth scan should be performed at 28-30 weeks gestation & repeated at
34-36 weeks gestation. There should be at least 3 weeks gap between the two ultrasounds and it should include
fetal biometry & amniotic fluid estimation.
• Pregnant women with GDM in whom blood glucose level is well controlled and there are no complications, should
go for routine antenatal care as per GoI guidelines.
• In pregnant women with GDM having uncontrolled blood glucose level or any other complication of pregnancy,
the frequency of antenatal visits should be increased to every 2 weeks in second trimester and every week in
third trimester.
• Monitor for abnormal foetal growth (macrosomia/growth restriction) and polyhydramnios at each ANC visit PW
with GDM to be diligently monitored for hypertension in pregnancy, proteinuria and other obstetric complications
• In pregnant women with GDM between 24-34 weeks of gestation and requiring early delivery, antenatal steroids
should be given as per GoI guidelines i.e. Inj. Dexamethasone 6 mg IM 12 hourly for 2 days. More vigilant
monitoring of blood glucose levels should be done for next 72 hours following injection. In case of raised blood
glucose levels during this period, adjustment of insulin dose should be made accordingly.

• Pregnant women with GDM are at an increased risk for foetal death in
utero and this risk is increased in PW requiring medical management.
Hence vigilant foetal surveillance is required.
• Foetal heart should be monitored by auscultation on each antenatal visit.
• The pregnant woman should be explained about Daily Fetal Activity
Assessment
• Woman to lie down on her side after a meal and note how long it takes for the
foetus to kick 10 times.
• If the foetus does not kick 10 times within 2 hrs, she should immediately
consult a healthcare worker and if required should be referred to a higher centre
for further evaluation.

• Pregnant women with GDM on insulin therapy with uncontrolled blood glucose levels (2 hr PPPG ≥120
mg/dl) or insulin requirement >20 U/day should be referred for delivery at CEmOC centres under care
of gynaecologist at least a week before the planned delivery.
• Such referred cases must get assured indoor admission or can be kept in a birth waiting home with
round the clock availability of medical staff for monitoring.
Timing of delivery
• GDM pregnancies are associated with delay in lung maturity of the foetus; so routine delivery prior to
39 weeks is not recommended.
• If a woman with GDM with well controlled plasma glucose has not already delivered spontaneously,
induction of labour should be scheduled at or after 39 weeks of pregnancy.
• In woman with GDM with poor plasma glucose control, those with risk factors like hypertensive disorder
of pregnancy, previous still birth and other complications should be delivered earlier. The timing of
delivery should be individualised by the obstetrician accordingly.
• Vaginal delivery should be preferred and LSCS should be done for obstetric indications only.
• In case of foetal macrosomia (estimated foetal weight > 4 Kg) consideration should be given for a
primary caesarean section at 39 weeks to avoid shoulder dystocia.
Labour and Delivery

• Pregnant women with GDM on insulin
require plasma glucose monitoring
during labour by a glucometer.
• The morning dose of insulin is withheld
on the day of induction/labour and the
PW should be started on 2 hourly
monitoring of plasma glucose.
• IV infusion with normal saline (NS) to
be started and regular insulin to be
added according to blood glucose levels
as per the table to t to the right

• All babies born to mothers with GDM are at risk for development of hypoglycaemia irrespective
of treatment whether they are on insulin or not and should be observed closely.
• All babies are, hence, to be checked for hypoglycaemia at or within one hour of delivery by
glucometer.
• All neonates should receive immediately essential newborn care with emphasis with early
breastfeeding to prevent hypoglycaemia.
• If required, the sick neonates should be immediately resuscitated as per GoI guidelines.
• Newborn should be monitored for hypoglycaemia (capillary blood glucose <44 mg/dl).
Monitoring should be started at 1 hour of delivery and continued every 4 hours (prior to next
feed) till four stable glucose values are obtained.
• Neonate should be also be evaluated for other neonatal complications like respiratory distress,
convulsions, hyperbilirubinaemia.
• Further details are found in the National Guidelines

• Immediate postpartum care women with GDM is not different from women without GDM
but these women are at high risk to develop Type 2 Diabetes mellitus in future.
• Maternal glucose levels usually return to normal after delivery.
• Nevertheless, a FPG & 2 hr PPPG is performed on the 3rd day of delivery at the place of
delivery. For this reason, GDM cases are not discharged after 48 hours unlike other
normal PNC cases.
• 6 weeks post partum: 75 g GTT at 6 weeks to evaluate glycaemic status of woman.
• Cut offs for normal blood glucose values are:
• Fasting plasma glucose: ≥ 126 mg/dl
• 75 g OGTT 2 hour plasma glucose
• Normal: < 140 mg/dl
• IGT: 140-199mg/dl
• Diabetes: ≥ 200 mg/dl

Bringing blood glucose in good control is almost entirely in the hands of the
pregnant woman with GDM
It is important that:
• The pregnant woman understands both the short- and the long-term potential
consequences of her condition (for her and her unborn child)
• Her family (husband and in-laws) understand what GDM is and why a change in
the woman’s/family’s dietary habits may be necessary
• The pregnant woman understands the importance of attending the clinic for
observation and follow-up
• The pregnant woman understands that, while GDM is transitional, both her and her
child at at increased risk of type 2 diabetes in the future

    • Carbohydrate foodsare essential for a healthy diet for mother and baby. • Once digested, carbohydrate foods are broken down to glucose, which goes into the blood stream. The type, amount and frequency of carbohydrate intake has a major influence on blood glucose readings. • Large amounts of carbohydrate foods eaten at one time will lead to high blood glucose level and should be avoided. It is better to spread carbohydrate foods over 3 small meals and 2-3 snacks each day than taking 3 large meals. • Complex carbohydrates (e.g. whole grain cereals) should be preferred over simple carbohydrates like foods with lots of added sugar or honey or foods that are made from refined white flour. • Counting the number of carbohydrates serves that a mother eats during the days will help her to eat the right amount.

    • Antenatal careof a pregnant woman with GDM should be provided by a gynaecologist, if available. • If GDM is diagnosed before 20 weeks of pregnancy, a foetal anatomical survey by USG should be performed at 18-20 weeks. • For all pregnancies with GDM, a foetal growth scan should be performed at 28-30 weeks gestation & repeated at 34-36 weeks gestation. There should be at least 3 weeks gap between the two ultrasounds and it should include fetal biometry & amniotic fluid estimation. • Pregnant women with GDM in whom blood glucose level is well controlled and there are no complications, should go for routine antenatal care as per GoI guidelines. • In pregnant women with GDM having uncontrolled blood glucose level or any other complication of pregnancy, the frequency of antenatal visits should be increased to every 2 weeks in second trimester and every week in third trimester. • Monitor for abnormal foetal growth (macrosomia/growth restriction) and polyhydramnios at each ANC visit PW with GDM to be diligently monitored for hypertension in pregnancy, proteinuria and other obstetric complications • In pregnant women with GDM between 24-34 weeks of gestation and requiring early delivery, antenatal steroids should be given as per GoI guidelines i.e. Inj. Dexamethasone 6 mg IM 12 hourly for 2 days. More vigilant monitoring of blood glucose levels should be done for next 72 hours following injection. In case of raised blood glucose levels during this period, adjustment of insulin dose should be made accordingly.

    • Pregnant womenwith GDM are at an increased risk for foetal death in utero and this risk is increased in PW requiring medical management. Hence vigilant foetal surveillance is required. • Foetal heart should be monitored by auscultation on each antenatal visit. • The pregnant woman should be explained about Daily Fetal Activity Assessment • Woman to lie down on her side after a meal and note how long it takes for the foetus to kick 10 times. • If the foetus does not kick 10 times within 2 hrs, she should immediately consult a healthcare worker and if required should be referred to a higher centre for further evaluation.

    • Pregnant womenwith GDM with good control of blood glucose (2 hr PPPG < 120 mg/dl) levels may be delivered at their respective health facility. • Pregnant women with GDM on insulin therapy with uncontrolled blood glucose levels (2 hr PPPG ≥120 mg/dl) or insulin requirement >20 U/day should be referred for delivery at CEmOC centres under care of gynaecologist at least a week before the planned delivery. • Such referred cases must get assured indoor admission or can be kept in a birth waiting home with round the clock availability of medical staff for monitoring. Timing of delivery • GDM pregnancies are associated with delay in lung maturity of the foetus; so routine delivery prior to 39 weeks is not recommended. • If a woman with GDM with well controlled plasma glucose has not already delivered spontaneously, induction of labour should be scheduled at or after 39 weeks of pregnancy. • In woman with GDM with poor plasma glucose control, those with risk factors like hypertensive disorder of pregnancy, previous still birth and other complications should be delivered earlier. The timing of delivery should be individualised by the obstetrician accordingly. • Vaginal delivery should be preferred and LSCS should be done for obstetric indications only. • In case of foetal macrosomia (estimated foetal weight > 4 Kg) consideration should be given for a primary caesarean section at 39 weeks to avoid shoulder dystocia.

    • Pregnant womenwith GDM on insulin require plasma glucose monitoring during labour by a glucometer. • The morning dose of insulin is withheld on the day of induction/labour and the PW should be started on 2 hourly monitoring of plasma glucose. • IV infusion with normal saline (NS) to be started and regular insulin to be added according to blood glucose levels as per the table to t to the right Special precaution during labour Presentation title Date 49 Source: National Guidelines for Diagnosis & Management of Gestational Diabetes Mellitus

    • All babiesborn to mothers with GDM are at risk for development of hypoglycaemia irrespective of treatment whether they are on insulin or not and should be observed closely. • All babies are, hence, to be checked for hypoglycaemia at or within one hour of delivery by glucometer. • All neonates should receive immediately essential newborn care with emphasis with early breastfeeding to prevent hypoglycaemia. • If required, the sick neonates should be immediately resuscitated as per GoI guidelines. • Newborn should be monitored for hypoglycaemia (capillary blood glucose <44 mg/dl). Monitoring should be started at 1 hour of delivery and continued every 4 hours (prior to next feed) till four stable glucose values are obtained. • Neonate should be also be evaluated for other neonatal complications like respiratory distress, convulsions, hyperbilirubinaemia. • Further details are found in the National Guidelines Immediate neonatal care for baby of mother with GDM Presentation title Date 50 Source: National Guidelines for Diagnosis & Management of Gestational Diabetes Mellitus

    • Immediate postpartumcare women with GDM is not different from women without GDM but these women are at high risk to develop Type 2 Diabetes mellitus in future. • Maternal glucose levels usually return to normal after delivery. • Nevertheless, a FPG & 2 hr PPPG is performed on the 3rd day of delivery at the place of delivery. For this reason, GDM cases are not discharged after 48 hours unlike other normal PNC cases. • 6 weeks post partum: 75 g GTT at 6 weeks to evaluate glycaemic status of woman. • Cut offs for normal blood glucose values are: • Fasting plasma glucose: ≥ 126 mg/dl • 75 g OGTT 2 hour plasma glucose • Normal: < 140 mg/dl • IGT: 140-199mg/dl • Diabetes: ≥ 200 mg/dl Post-delivery follow-up of women with GDM Presentation title Date 51 Source: National Guidelines for Diagnosis & Management of Gestational Diabetes Mellitus

    Bringing blood glucosein good control is almost entirely in the hands of the pregnant woman with GDM It is important that: • The pregnant woman understands both the short- and the long-term potential consequences of her condition (for her and her unborn child) • Her family (husband and in-laws) understand what GDM is and why a change in the woman’s/family’s dietary habits may be necessary • The pregnant woman understands the importance of attending the clinic for observation and follow-up • The pregnant woman understands that, while GDM is transitional, both her and her child at at increased risk of type 2 diabetes in the future Patient Education - Key to good outcomes Presentation title Date 53
