Pregnancy can lead to gestational diabetes, increasing the chances of developing type 2 diabetes and heart disease.
By making dietary improvements and staying active, you can reduce these risks for yourself and your family.
Here are some additional tips to help lower your future risk of type 2 diabetes:
- Monitor your blood sugar levels regularly to catch any potential issues early.
- Stay active and incorporate exercise into your daily routine to help maintain a healthy weight.
- Eat a balanced diet rich in fruits, vegetables, whole grains, and lean proteins to support overall health.
- Avoid sugary drinks and processed foods high in added sugars to help manage blood sugar levels.
- Work with your healthcare provider to develop a personalized plan for monitoring and managing your risk factors for type 2 diabetes.
By taking these steps, you can significantly reduce your risk of developing type 2 diabetes and improve your overall health and well-being.
What is gestational diabetes?
About 1 in 7 to 8 pregnant women in Australia experience gestational diabetes.
Screening for gestational diabetes typically occurs between 24-28 weeks through a glucose tolerance test.
If diagnosed, managing the condition involves monitoring blood sugar levels, maintaining a healthy diet, and engaging in physical activity to lower risks.
It is important for women with gestational diabetes to work closely with their healthcare providers to ensure proper management of the condition and to minimize potential risks for both the mother and the baby.
Managing gestational diabetes also includes regular check-ups and monitoring of fetal growth to ensure the health and well-being of both mother and baby throughout the pregnancy.
Type 2 diabetes
If left undiagnosed, type 2 diabetes can have severe health implications when complications arise.
Early symptoms include excessive thirst, frequent urination, blurred vision, and fatigue.
Long-term effects may include heart disease, nerve damage, kidney disease, and diabetic retinopathy.
Who’s at risk of gestational diabetes
Gestational diabetes can develop at any stage during pregnancy, impacting the body’s insulin production.
Identifying and managing the condition early can decrease risks for both mother and baby.
Other symptoms of gestational diabetes may include increased hunger, weight loss despite increased appetite, frequent infections, and slow healing of cuts and bruises.
It is important to consult with a healthcare provider if you experience any of these symptoms during pregnancy, as early detection and management of gestational diabetes are crucial for the health of both the mother and the baby.
How gestational diabetes can affect your pregnancy
Most women with gestational diabetes have normal pregnancies, but complications can arise, such as having a larger baby.
Managing gestational diabetes risks involves adopting a healthy diet, regular physical activity, and consistent monitoring.
- Having a larger-than-average baby
- Baby developing low blood sugar or jaundice
- Risk of stillbirth
- Increased risk of pre-eclampsia
- Premature birth
Gestational diabetes increases the risk of developing type 2 diabetes later on. It is important to follow your healthcare provider’s recommendations for managing gestational diabetes to ensure a healthy pregnancy and reduce the risk of future health complications.
Screening for gestational diabetes
During the first antenatal appointment at 8 to 12 weeks, healthcare providers assess the risk of gestational diabetes through a series of questions.
If you have risk factors, you may undergo an oral glucose tolerance test (OGTT) lasting approximately 2 hours.
The OGTT involves fasting, consuming a glucose drink, and a blood sample taken after 2 hours.
Typically conducted between 24 and 28 weeks of pregnancy, earlier if a history of gestational diabetes is present.
Regular prenatal appointments are important for monitoring the health of both the mother and baby.
In some cases, insulin injections may be necessary to control blood sugar levels effectively.
It’s essential to follow the treatment plan provided by healthcare professionals to ensure a healthy pregnancy and delivery.
Managing gestational diabetes can reduce the risk of complications for both mother and baby, such as macrosomia (large birth weight) and hypoglycemia after birth.
Long-term effects of gestational diabetes
Gestational diabetes typically resolves postpartum but increases the likelihood of future gestational diabetes or type 2 diabetes.
A blood test between 6 to 13 weeks after childbirth checks for diabetes, with yearly tests if results are normal.
Maintaining a healthy weight, balanced diet, and regular exercise can help reduce the risk of diabetes.
Babies born to mothers with gestational diabetes may have a higher risk of diabetes or obesity later in life.
Planning future pregnancies
If you have a history of gestational diabetes, undergo diabetes screening before planning a pregnancy.
If diabetes is present, seek assistance from a pre-conception clinic to manage the condition before conceiving.
If you experienced gestational diabetes in a prior pregnancy, undergo tests earlier and between 24-28 weeks of pregnancy.
Monitor blood sugar levels as recommended by your healthcare provider, and seek guidance from a GP if uncertain.
After giving birth, it is important to continue monitoring your blood sugar levels regularly as gestational diabetes can increase the risk of developing type 2 diabetes later in life.
Follow up with your healthcare provider for postpartum screening to assess your risk for developing type 2 diabetes and to ensure your blood sugar levels are within a healthy range.
Make lifestyle changes such as maintaining a healthy diet, engaging in regular physical activity, and maintaining a healthy weight to reduce the risk of developing type 2 diabetes.
If you plan to have more children in the future, discuss your history of gestational diabetes with your healthcare provider to develop a plan for managing your risk during pregnancy.
Postnatal and future follow-up care
Gestational diabetes may disappear post-birth but increases the risk of type 2 diabetes within 5 years.
Some individuals with gestational diabetes may have had undiagnosed diabetes before pregnancy, requiring lifelong treatment.
Postpartum testing and annual evaluations are recommended, emphasizing the importance of maintaining a healthy lifestyle for prevention.
Inform healthcare providers about any pregnancy complications for continued care.
Children born to mothers with gestational diabetes are at a higher risk of obesity and diabetes.
Breastfeeding if you have gestational diabetes
Well-controlled gestational diabetes should not interfere with breastfeeding.
Breast milk quality remains unaffected with proper diabetes management.
Tips for getting breastfeeding established
Express and store colostrum by 37 weeks of pregnancy for potential baby use.
Seek support from healthcare providers regarding lactation and ensure immediate skin-to-skin contact after birth for initiating breastfeeding.
Maintain regular breastfeeding sessions to stabilize the baby’s blood glucose levels.
Planning future pregnancies
The risk of developing diabetes in future pregnancies is higher for women with a history of gestational diabetes.

It is important for women with a history of gestational diabetes to monitor their blood sugar levels regularly, especially during future pregnancies. They should work closely with their healthcare provider to develop a plan for maintaining healthy blood sugar levels during pregnancy. Making lifestyle changes, such as eating a balanced diet and staying physically active, can also help reduce the risk of developing diabetes in future pregnancies. Regular follow-up appointments with a healthcare provider are essential to monitor and manage diabetes risk factors.
Abstract
The diagnosis of gestational diabetes mellitus (GDM) identifies patients with a pancreatic β-cell defect that can lead to a higher risk of diabetes after pregnancy. The causes of β-cell defects in GDM involve genetic variants and autoimmunity related to type 1 diabetes. Lifestyle changes and medications can prevent or delay type 2 diabetes in individuals at risk. Postpartum glucose tolerance assessments are essential for identifying diabetes and evaluating diabetes risk. Monitoring blood sugar levels and making necessary lifestyle changes can lower the risk of type 2 diabetes. Close follow-up and timely medical intervention may be required if diabetes develops. Children of mothers with GDM require education, monitoring, and lifestyle guidance to mitigate obesity and diabetes risks.
Upon completing the educational activity, participants should be able to recognize the diabetes risk after GDM, understand β-cell dysfunction causes, select clinical approaches to lower diabetes risk, and assess the effectiveness of these approaches. The activity is valuable for endocrinologists.

A case study of a Hispanic woman with GDM illustrates the challenges associated with the condition, emphasizing its increasing incidence and physiological implications. GDM indicates an underlying β-cell defect, necessitating postpartum screening and diabetes prevention strategies to reduce long-term health risks for both mothers and children.
The article discusses current postpartum screening guidelines for diabetes, factors increasing diabetes risk, strategies for preventing or delaying diabetes, and uncertainties in managing children born to mothers with GDM pregnancies.
Professional organizations generally recommend diabetes screening for women with gestational diabetes mellitus (GDM) around the time of the first postpartum visit. The American Diabetes Association (ADA) suggests screening at 6–12 weeks after delivery, while the World Health Organization recommends screening at least 6 weeks after delivery. Both organizations advise a 75-g oral glucose tolerance test (OGTT). The United Kingdom’s National Institute for Health and Clinical Excellence (NICE) recommends screening with a fasting glucose at the 6-week postpartum visit. There are no official guidelines for hemoglobin A1C (A1C) as a screening test in the postpartum period. Other measures like fructosamine testing could be considered because of their stability during the postpartum period.
What we recommend
Regular monitoring for diabetes postpartum is essential. The ADA recommends reevaluation no more than every 3 years if initial glucose levels are normal. If postpartum glycemia is impaired, reassessment at 1 year is suggested. Long-term screening options include A1C, fasting glucose, and a 75-g OGTT. Criteria for a diabetes diagnosis include an A1C of at least 6.5%, fasting plasma glucose of at least 126 mg/dl, and/or 2-hour plasma glucose of at least 200 mg/dl on a 75-g OGTT.
Factors That May Influence Diabetes Risk
For those with a history of GDM, monitoring glucose levels for any rise is crucial. Increasing glucose levels may indicate worsening β-cell function. Lifestyle adjustments can aid in preventing weight gain and monitoring for metabolic disorders associated with insulin resistance is recommended.
Contraceptive options
Ensuring proper family planning is crucial for women who have experienced GDM to lower their risk of diabetes. The use of hormonal contraception may have varying effects on diabetes risk. Additionally, breastfeeding could potentially improve glucose tolerance for women who have recently had GDM.
Breast-feeding
Detecting GDM is typically done during routine clinical care. Women who have had GDM are an important group to focus on for diabetes prevention efforts. Lifestyle changes and medication intervention can help reduce the risk of developing diabetes.
Prevention and Treatment
Following GDM, prioritizing lifestyle modifications is key in preventing diabetes. These changes can offer numerous benefits beyond just reducing diabetes risk, such as addressing other health concerns related to obesity. Regular physical activity can help improve metabolic issues, even without significant weight loss. It is essential to encourage lifestyle adjustments for women with past GDM who are at risk of developing T2D. Consideration of pharmacological intervention should only happen if lifestyle changes do not yield the desired results. Regularly monitoring A1C levels is critical for early detection and management of diabetes.
Children born to mothers with GDM face a higher risk of obesity and diabetes later in life. Breastfeeding has been shown to be protective against childhood obesity and the development of T2D. By implementing lifestyle interventions and monitoring glucose levels in childhood, these risks can be minimized. Promoting breastfeeding and advocating for healthy lifestyle habits are vital in preventing obesity in children whose mothers had diabetes.
Women with T2D risk factors, such as obesity and certain ethnic backgrounds, require close monitoring. Some women who have had GDM may exhibit other forms of β-cell dysfunction, like autoantibodies targeting islet antigens. Screening and consistent monitoring are crucial for early detection and effective management. In some cases, genetic testing may be necessary to identify specific types of diabetes.
The updated diagnostic criteria for GDM may lead to more cases being identified. Under the new criteria, lifestyle changes and regular monitoring are recommended to mitigate the long-term risk of diabetes. Monitoring glucose levels postpartum and conducting regular assessments are essential for women at risk of developing diabetes after GDM. Lifestyle modifications and early monitoring can aid in maintaining or restoring β-cell function.
By implementing lifestyle changes and routine monitoring, the risk of developing diabetes post-GDM can be reduced. Weight management, counseling, and prompt intervention are crucial aspects of diabetes risk management. Breastfeeding and lifestyle adjustments can also positively impact the health of the child in the future. Medication should only be considered after thorough monitoring and diagnosis.
