Gestational diabetes increases the risk of developing type 2 diabetes after pregnancy. Statistics from Diabetes UK show that women with diabetes are seven times more likely to develop type 2 diabetes later in life. According to NISS, 50% of women with gestational diabetes will develop type 2 diabetes within 2 years.
In the year A comparison of 28 studies published in Diabetes in 2002 found that fasting during pregnancy was the most common risk factor for future type 2 diabetes.
The cumulative incidence of type 2 diabetes increased significantly within 5 years after delivery and was observed 10 years later. Fasting glucose levels during pregnancy generally increase the risk of type 2 diabetes. Postpartum diabetes diagnosis
It is recommended to have a 6-week fasting glucose blood test or HbA1c blood test after 6 weeks to make sure you are free of diabetes.
A repeat GTT is not recommended to confirm the presence of overt diabetes (NICE guidelines February 2015). However, it may still be offered in Scotland and Ireland or in hospitals that do not follow NICE recommendations.
Many women worry about having a fasting glucose test when they are breastfeeding or when their newborn baby is too young to participate in blood tests. If you have these concerns, you may want to opt for an HbA1c blood test after 13 weeks. You don’t need to fast, and it’s a simple blood test that can be done at your local GP surgery.
After your baby is born, you should eat normal food. Some hospitals recommend that you continue to monitor your blood sugar levels after giving birth. If you do, get ready to see some top reads. It may take some time for your hormones to stabilize, so it is recommended that you get an accurate diabetes test after at least 6 weeks.
If you feel sick or have hypo or hyper type symptoms, you should check your blood sugar level and consult a medical professional.
The World Health Organization recommends the following blood glucose levels for diabetes.
NICE guidelines for England and Wales. [2008] 1.6.9 State the symptoms of hyperglycemia in women with gestational diabetes. ] ] Offer a plasma glucose test 6-13 weeks postpartum to rule out diabetes (for practical reasons this may be as early as 6 weeks postpartum). If a fasting plasma glucose test is not performed within 13 weeks, offer a plasma glucose or HbA1c test after 13 weeks. Do not offer 75 g of 2-hour OGTT frequently. [NEW 2015] TEST RESULTS 1.6.12 Fertility Test for Fasting Women: Women with fasting plasma glucose levels below 6.0 mmol/L are at low risk of current diabetes, should continue postpartum, lifestyle (including weight control) diet and physical activity exercise), require annual blood glucose testing to determine their risk of developing type 2 diabetes, and are given advice and guidance. It is in line with NICE guidelines for the prevention of type 2 diabetes [11]. Advise women with plasma glucose levels between 6.0 and 6.9 mmol/liter of their risk of developing type 2 diabetes and provide them with advice, guidance and interventions based on NICE guidelines to prevent type 2 diabetes [11]. Advise women with a fasting plasma glucose level of 7.0 mmol/L or greater that they have type 2 diabetes and offer diagnostic testing to confirm diabetes. ] Postpartum lifestyle counseling (including weight management, diet, and exercise) requires annual blood glucose testing and counseling and guidance to determine their risk of developing type 2 diabetes. According to NICE guidelines for the prevention of type 2 diabetes [11]. Women with HbA1c levels between 39 and 47 mmol/mol (5.7% and 6.4%) are at risk for type 2 diabetes and advised on type 2 diabetes prevention according to NICE guidelines. [11] Advise women with an HbA1c level of 48 mmol/mol (6.5%) or higher to have type 2 diabetes and refer them for further care. [NEW 2015] Annual Screening 1.6.14 Offer women with gestational diabetes an annual HbA1c test, negative for diabetes. [New 2015] Future pregnancy 1.6.15 For women with diabetes during pregnancy, self-monitoring of blood glucose or OGTT. If the first OGTT result is positive for early pregnancy, follow-up OGTT (see recommendation 1.2.6). [2008, revised 2015]
SIGN guidelines for Scotland 7.12 Follow-up of women with GDM A diagnosis of GDM indicates that women are at increased risk of developing type 2 diabetes in the future. The rate of progression to type 2 diabetes in women with previous GDM varies (15–50% cumulative incidence over five years) and is influenced by other risk factors such as ethnicity, obesity, and physical activity. A Cochrane review concluded that combining exercise or diet can promote weight loss. Pharmacological and intensive lifestyle interventions reduce the onset of type 2 diabetes in people with impaired glucose tolerance, including women with previous gestational diabetes. No evidence was found to determine when the next test should be performed. C Women who develop GDM need diet, weight management, and exercise. Women who develop GDM should remember that preconception counseling and appropriate testing are needed to detect the development of type 2 diabetes. If diabetes does not occur after induction, glucose tolerance should be assessed clinically after at least six weeks with minimal fasting glucose and 75 g OGTT. Thereafter, glycemic assessment using fasting glucose or HbA1c should be performed annually. The World Health Organization recommends that blood glucose levels for diabetes should be as follows: venous plasma glucose (FPG) ≥7.0 mmol/L; or intravenous plasma glucose ≥11.1 mmol/L after a 75 g oral glucose load (oral glucose tolerance test (OGTT)). A HbA1c of 48 mmol/mol (6.5%) is recommended for the diagnosis of diabetes.
HSE Guidelines for Ireland 5.5 Childbirth 5.5.1 Postpartum Blood Glucose Monitoring After delivery of the placenta, maternal blood glucose and insulin levels can return to normal rapidly. ● Insulin therapy should be discontinued after delivery. SMBG should be discontinued when blood glucose returns to normal. If hyperglycemia persists, diabetes should be suspected and investigated. Pregnant 75g OGTT, using WHO criteria, for nonpregnant women, 6 weeks postpartum and annually WHO recommendations for diabetes screening and intermittent hyperglycemia in nonpregnant women: Diabetes diagnosis: fasting plasma glucose ≥7.0 mmol/L or 2- hour plasma glucose* ≥11.1 mmol/l Impaired glucose tolerance test (IGT): Impaired fasting plasma glucose (IFG) test: plasma glucose 6.1 to 6.9 mmol/l or 2-hour plasma glucose*
HSE Guidelines – Antenatal and Postnatal Guidelines for the Management of Diabetes in Pregnancy and Diabetes.
An annual HbA1c blood test is recommended for diabetes. Type 2 diabetes occurs when your body does not produce enough insulin or when your body’s cells do not respond to insulin, resulting in insulin resistance.
Knowing the reasons for the diagnosis of type 2 diabetes later, it is recommended to consider diet and lifestyle changes that reduce the chance of the diagnosis.
We rarely see women with type 1 diabetes after pregnancy, but gestational diabetes can be a trigger for a diagnosis of type 1 diabetes.
As a result of gestational diabetes, your baby is six times more likely to develop diabetes, and is more likely to be obese (body mass index greater than 30) later in life.
