Sometimes this is abbreviated to GDM. Gestational Diabetes can cause problems for you and your baby, during pregnancy and after birth. The risks can be reduced if the condition is detected and well managed. You may be offered this test at any stage during your pregnancy, up to 36 weeks. If you are more than 36 weeks gestation, your midwife or obstetrician will discuss your options, if there are any signs that GDM is developing.  \nGestational diabetes is high blood sugar that develops during pregnancy and usually disappears after giving birth. It can happen at any stage of pregnancy but is more common in the second or third trimester. It happens when your body cannot produce enough insulin – a hormone that helps control blood sugar levels – to meet your extra needs in pregnancy.  \nWe invite anyone within one or more of the following groups , to have an OGTT:  \n􀁸 Family history of Type 1 or Type 2 Diabetes (Close relatives such as your parents or siblings)  \n􀁸 Confirmed polycystic ovary disease  \n􀁸 Body Mass Index over 30kg/m²  \n􀁸 Previous unexplained still birth  \n􀁸 Previous baby weighing over 4 .5kg or plotting above 95th growth centile  \n􀁸 Previous Gestational Diabetes (GDM)  \n􀁸 South Asian, Black or African Caribbean or Middle Eastern background (even if you were born in the UK) .  \nYou may not have any of the above risk factors, but something may have been found during your pregnancy which might suggest Gestational Diabetes is developing, such as:  \n􀁸 Glucose detected on a urine dip test (either more than once or higher levels on one occasion)  \n􀁸 Polyhydramnios (excess fluid around the baby confirmed on ultrasound scan)  \n􀁸 Ultrasound scan showing the measurement of your baby’s tummy plots above the 97th growth centile  \n􀁸 Ultrasound scan measurement showing the estimated weight of your baby is increasing rapidly  \nIt may be suggested that you have this test repeated at different times during pregnancy if new risk factors develop. You can choose to decline this test or stop the test at anytime. Please talk to your midwife if you wish to discuss alternatives. However, management of GDM is more effective when detected early.  \nHow should I prepare?  \nFrom midnight the night before the test you can drink water but you must not  \n􀁸 eat or drink anything (except water)  \n􀁸 chew gum  \n􀁸 smoke  \n􀁸 vape  \n􀁸 apply nicotine patches  \nYou may only take any prescribed medications if required (if your medications need to be taken with food, or they are over the counter vitamins/supplements, delay the dose until after your OGTT test) .  \nWhat will happen?  \nThe OGTT consists of 2 blood tests taken 2 hours apart. After the first blood sample is taken, you will be given a very sweet drink called Polycal®, which you need to drink within 5 minutes. You will then be asked to sit in the waiting room for 2 hours , you may drink water to thirst, but we ask you to stay seated as much as possible, as moving around can affect the accuracy of the results. Then a further blood sample will be taken.  \nAfter the second blood sample has been taken, the test is complete and you can go home. You are welcome to have something to eat and drink in the waiting room before you leave.  \nDuring the test you must not eat, drink (except water) , chew gum, smoke, vape or apply nicotine patches because these things can affect the accuracy of the results.  \nWe ask you to stay at the hospital and sit down for the 2 hour wait, as physical activity can affect the accuracy of the results.  \nIf the above guidance is not adhered to, the test will be stopped, and we will  \nrebook it for another day.  \nIf you are feel","cbCainZVrnqcPDhU","https://ap.wps.com/l/cbCainZVrnqcPDhU","pdf",655075,"English","# Why am I having this test?\n# How should I prepare?\n# What will happen?\n# What should I bring with me?\n# How will I get my results?\n# Contact details","[{\"question\":\"Why have I been invited for the OGTT during pregnancy?\",\"answer\":\"The test is offered because you may have risk factors for developing Gestational Diabetes (GDM).
