How Do You Get Tested For Gestational Diabetes?

Glucose Screening Tests During Pregnancy

Glucose Screening Tests During Pregnancy

TWO-STEP TESTING During the first step, you will have a glucose screening test: You DO NOT need to prepare or change your diet in any way. You will be asked to drink a liquid that contains glucose. Your blood will be drawn 1 hour after you drink the glucose solution to check your blood glucose level. If your blood glucose from the first step is too high, you will need to come back for a 3-hour glucose tolerance test. For this test: DO NOT eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.) You will be asked to drink a liquid that contains glucose, 100 grams (g) . You will have blood drawn before you drink the liquid, and again 3 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked. Allow at least 3 hours for this test. ONE-STEP TESTING You need to go to the lab one time for a 2-hour glucose tolerance test. For this test: DO NOT eat or drink anything (other than sips of water) for 8 to 14 hours before your test. (You also cannot eat during the test.) You will be asked to drink a liquid that contains glucose (75 g). You will have blood drawn before you drink the liquid, and again 2 more times every 60 minutes after you drink it. Each time, your blood glucose level will be checked. Allow at least 2 hours for this test. Continue reading >>

Gestational Diabetes

Gestational Diabetes

Between three and eight per cent of women will get gestational diabetes between the 24th and the 28th week of pregnancy, sometimes earlier. It usually goes away after the baby is born. Women who are more likely to get gestational diabetes are: older mothers women who have a family history of type 2 diabetes women who are overweight women who are from certain ethnic backgrounds, including South Asian, Vietnamese, Chinese, Middle Eastern and Polynesian/Melanesian. Other women at risk include those who have had gestational diabetes, polycystic ovarian syndrome, large babies or birth complications in the past What is gestational diabetes? The hormone insulin moves glucose or sugar from your blood and into your body’s cells, where it is used for energy. When you have diabetes, this process is blocked and your cells become 'insulin resistant'. This causes you to have too much glucose in your blood. In pregnancy, the hormones from the placenta, which help your baby to grow, can cause your cells to become insulin resistant. Usually in pregnancy the body produces more insulin to counter this. In some women, however, this doesn’t happen and they develop gestational diabetes. There are many health issues associated with gestational diabetes, including that both the mother and baby will have an increased risk of developing type 2 diabetes later in life. During the pregnancy, gestational diabetes can lead to excessive sugars and fats crossing the placenta, which can have an effect on the baby’s growth, usually making them bigger. Giving birth to larger babies can also lead to problems with the birth. Sometimes, even though it might not seem to make sense, some babies (particularly larger babies) are born with blood sugar levels that are too low – this is called hypoglycaemia Continue reading >>

Gestational Diabetes

Gestational Diabetes

Gestational diabetes is high blood sugar that develops during pregnancy and usually disappears after giving birth. It can occur at any stage of pregnancy, but is more common in the second half. It occurs if your body cannot produce enough insulin – a hormone that helps control blood sugar levels – to meet the extra needs in pregnancy. Gestational diabetes can cause problems for you and your baby during and after birth. But the risk of these problems happening can be reduced if it's detected and well managed. Who's at risk of gestational diabetes Any woman can develop gestational diabetes during pregnancy, but you're at an increased risk if: your body mass index (BMI) is above 30 – use the healthy weight calculator to work out your BMI you previously had a baby who weighed 4.5kg (10lbs) or more at birth you had gestational diabetes in a previous pregnancy one of your parents or siblings has diabetes your family origins are south Asian, Chinese, African-Caribbean or Middle Eastern If any of these apply to you, you should be offered screening for gestational diabetes during your pregnancy. Symptoms of gestational diabetes Gestational diabetes doesn't usually cause any symptoms. Most cases are only picked up when your blood sugar level is tested during screening for gestational diabetes. Some women may develop symptoms if their blood sugar level gets too high (hyperglycaemia), such as: But some of these symptoms are common during pregnancy anyway and aren't necessarily a sign of a problem. Speak to your midwife or doctor if you're worried about any symptoms you're experiencing. How gestational diabetes can affect your pregnancy Most women with gestational diabetes have otherwise normal pregnancies with healthy babies. However, gestational diabetes can cause problems s Continue reading >>

Diagnosis

Diagnosis

Print Medical experts haven't agreed on a single set of screening guidelines for gestational diabetes. Some question whether gestational diabetes screening is needed if you're younger than 25 and have no risk factors. Others say that screening all pregnant women is the best way to identify all cases of gestational diabetes. When to screen Your doctor will likely evaluate your risk factors for gestational diabetes early in your pregnancy. If you're at high risk of gestational diabetes — for example, your body mass index (BMI) before pregnancy was 30 or higher or you have a mother, father, sibling or child with diabetes — your doctor may test for diabetes at your first prenatal visit. If you're at average risk of gestational diabetes, you'll likely have a screening test during your second trimester — between 24 and 28 weeks of pregnancy. Routine screening for gestational diabetes Initial glucose challenge test. You'll drink a syrupy glucose solution. One hour later, you'll have a blood test to measure your blood sugar level. A blood sugar level below 130 to 140 milligrams per deciliter (mg/dL), or 7.2 to 7.8 millimoles per liter (mmol/L), is usually considered normal on a glucose challenge test, although this may vary by clinic or lab. If your blood sugar level is higher than normal, it only means you have a higher risk of gestational diabetes. You'll need a glucose tolerance test to determine if you have the condition. Follow-up glucose tolerance testing. You'll fast overnight, then have your blood sugar level measured. Then you'll drink another sweet solution — this one containing a higher concentration of glucose — and your blood sugar level will be checked every hour for three hours. If at least two of the blood sugar readings are higher than normal, you'll Continue reading >>

Gestational Diabetes Test: What To Expect

Gestational Diabetes Test: What To Expect

Gestational diabetes occurs only during pregnancy, and it usually goes away once you’ve delivered your baby. Pregnant women with gestational diabetes have higher than normal blood sugar. This is because their bodies aren’t producing enough insulin. Insulin is a hormone that regulates blood sugar. Gestational diabetes can happen at almost any time during pregnancy, but it typically occurs between 24 to 28 weeks. This is also when testing typically takes place. Getting tested for gestational diabetes is an important part of prenatal care. Doctors test all pregnant women at least once during pregnancy. Your doctor will consider your risk factors when determining when you should have this test and how often you should have it. Learn what to expect during this test and how to prepare. Many women who have gestational diabetes have no symptoms. If symptoms do appear, it’s possible you may overlook them because they’re similar to typical pregnancy symptoms. These symptoms may include: frequent urination extreme thirst fatigue snoring You should call your doctor if you’re experiencing these symptoms to a greater degree than is normal for you. The exact cause of gestational diabetes is unknown, but it may be due to hormones your placenta produces. These hormones help your baby grow, but they can also stop insulin from doing its job. If your body can’t make enough insulin, the sugar in your bloodstream stays put. The sugar is then unable to convert into energy in the cell. This is called insulin resistance. If it’s left untreated, gestational diabetes can have significant consequences for both you and your baby. Once your doctor knows you have this condition, they’ll work with you on a treatment plan to ensure your and your baby’s health. Any pregnant woman can g Continue reading >>

Diagnosis And Management Of Gestational Diabetes Mellitus

Diagnosis And Management Of Gestational Diabetes Mellitus

Gestational diabetes occurs in 5 to 9 percent of pregnancies in the United States and is growing in prevalence. It is a controversial entity, with conflicting guidelines and treatment protocols. Recent studies show that diagnosis and management of this disorder have beneficial effects on maternal and neonatal outcomes, including reduced rates of shoulder dystocia, fractures, nerve palsies, and neonatal hypoglycemia. Diagnosis is made using a sequential model of universal screening with a 50-g one-hour glucose challenge test, followed by a diagnostic 100-g three-hour oral glucose tolerance test for women with a positive screening test. Treatment consists of glucose monitoring, dietary modification, exercise, and, when necessary, pharmacotherapy to maintain euglycemia. Insulin therapy is the mainstay of treatment, although glyburide and metformin may become more widely used. In women receiving pharmacotherapy, antenatal testing with nonstress tests and amniotic fluid indices beginning in the third trimester is generally used to monitor fetal well-being. The method and timing of delivery are controversial. Women with gestational diabetes are at high risk of subsequent development of type 2 diabetes. Lifestyle modification should therefore be encouraged, along with regular screening for diabetes. Evidence for screening, diagnosing, and managing gestational diabetes mellitus has continued to accrue over the past several years. In 2003, the U.S. Preventive Services Task Force1 (USPSTF) and the Cochrane Collaboration2 found insufficient evidence to recommend for or against screening for or treating gestational diabetes. However, a subsequent randomized controlled trial (RCT) found that screening and intervention for gestational diabetes were beneficial.3 Nonetheless, in 2008, Continue reading >>

Glucose Screening And Glucose Tolerance Tests

Glucose Screening And Glucose Tolerance Tests

Why do I need a glucose screening test during pregnancy? Most healthcare practitioners routinely recommend a glucose screening test (also called a glucose challenge test or GCT) between 24 and 28 weeks of pregnancy to check for gestational diabetes. Gestational diabetes is a high blood sugar condition that some women get during pregnancy. Between 2 and 5 percent of expectant mothers develop this condition, making it one of the most common health problems during pregnancy. And because the condition rarely causes any symptoms, testing is the only way to find out whether you have it. Like any screening test, the GCT won't give you a diagnosis. Instead, it's designed to identify as many women as possible who may have a problem and need more testing to find out. So a positive result doesn't mean that you have gestational diabetes. In fact, only about a third of women who test positive on the glucose screen actually have the condition. If you test positive on the screening, you'll need to take the glucose tolerance test (GTT) – a longer, more definitive test that tells you for sure whether you have gestational diabetes. Your practitioner may want you to be screened earlier than 24 weeks if a routine urine test shows a lot of sugar in your urine or if you're considered high risk. If the results are normal, you'll be screened again at 24 to 28 weeks. Of course, if you were diagnosed with diabetes before pregnancy, you won't need to be screened. Instead, you'll continue to work with your practitioner to manage your condition during pregnancy. How is the glucose screening test done? When you arrive for the test, you're given a sugar solution that contains 50 grams of glucose. The stuff tastes like a very sweet soda pop (it comes in cola, orange, or lime flavor), and you have to Continue reading >>

Are We Testing For Gestational Diabetes Too Late?

Are We Testing For Gestational Diabetes Too Late?

A new study shows that babies are already showing the effects of gestational diabetes by the time expectant moms are tested for it. So are we testing too late? No one likes the glucose tolerance test—having to chug down that nasty orange drink, and hoping there are no side effects. Unfortunately, screening for high blood sugar is a necessity in pregnancy, as gestational diabetes mellitus (GDM) can cause problems ranging from stillbirth to childhood obesity. But a new study published in journal Diabetes Care suggests that unborn babies are showing the effects of GDM before expectant mothers are even tested for it, throwing the screening's relevance into question. Should pregnant women be tested even earlier? Diagnosis after baby is already affected Researchers looked at data from over 4,000 pregnant women to measure baby's growth, as large size is an indicator of gestational diabetes, and compared that info to the 171 moms who actually developed GDM later on. They also looked at which women were obese, another risk factor for GDM. "Gestational diabetes and obesity were both associated with accelerated growth of the [baby's] abdomen between 20 and 28 weeks," study author Gordon Smith, M.D., Ph.D., the head of the department of obstetrics and gynecology at the University of Cambridge in the UK, tells Fit Pregnancy. "In relation to gestational diabetes, measurements were normal at 20 weeks, but were large by 28 weeks. Women who were both obese and had a diagnosis of gestational diabetes were almost five times more likely to have a baby with a large abdominal measurement at 28 weeks." Because GDM wasn't actually diagnosed in the women until 28 weeks, "the effects of gestational diabetes [are] already present at the time we normally make the diagnosis," Dr. Smith says.

Testing For Gestational Diabetes

Testing For Gestational Diabetes

Your ‘booking appointment’ is your first appointment with your midwife or GP to talk about your pregnancy. This usually happens around 8–12 weeks of pregnancy. During that appointment, the midwife or GP will carry out some routine tests (tests offered to every woman) and ask lots of questions. Some of the questions will help find out if you are at risk of developing gestational diabetes (they will be looking to see if you have any of the risk factors). If you are considered at high risk, you will be offered a test. Agreeing to these tests is important because if you have gestational diabetes, there is a small increased risk of serious birth complications. Finding out if you have it and treating the condition can reduce those risks. The key things you need to know are: If you are at risk of gestational diabetes but don’t take the test, it can’t be found and treated. This may increase the risk to you and your baby. If you are diagnosed with gestational diabetes, you will have more check-ups and extra care during your pregnancy and labour. In some women, gestational diabetes responds to changes in diet and exercise, while others will need to take medication, which may be in the form of tablets or insulin injections. "I wasn’t obviously skinny, but I wasn’t massively obese either… I had no symptoms whatsoever. I had no expectation that the Lucozade test would be anything other than a formality." What if I had gestational diabetes in an earlier pregnancy? If you have had gestational diabetes in a previous pregnancy, you need to take action before you become pregnant again. You need to be scanned for diabetes when you are planning your pregnancy to make sure that your blood glucose levels are safe. You also need to be tested as soon as possible after your book Continue reading >>

Gestational Diabetes Alternative Tests, Causes & Diagnosis

Gestational Diabetes Alternative Tests, Causes & Diagnosis Gestational Diabetes Alternative Tests, Causes & Diagnosis This entry was posted on February 13, 2018 by Elizabeth MacDonald. Did you know that there are options to drinking the glucose test drink? Well, there are! And talking to your doctor about it is easy. You don't have to decline it or feel like you are 'opting out' of anything - instead, you are allowing your body to get a more accurate reading during the test! You see, real foods will give true results. According to the American Pregnancy Association: Pregnant women can develop a condition known as Gestational Diabetes (diabetes brought on by pregnancy) whichcan pose arisk to both mother and baby. A glucose tolerance test is a common type of testing for potential gestational diabetes. Typically, the body breaks down carbohydrates into glucose causing insulin to be released. The insulin pulls the glucose from the blood and transfers it to the cells to be stored for energy. When a woman is pregnant, the body leaves some glucose in the blood so that it can be passed to the baby through the placenta and umbilical cord. Gestational Diabetes is diagnosed when there is too high of an amount of glucose found in the blood while pregnant. Science has not found one specific cause for gestational diabetes, but the following are all possible links: The Dangers and Complications of Gestational Diabetes: Birth Injuries (Such as shoulder dystocia) Large Babies: Although over 70% of Large Babies are born to mothers without gestational diabetes, women with the condition have been linked to having above average-sized babies. Neonatal Hypoglycemia: low blood sugar in baby. Fetal Hyperinsulinemia: the baby has higher levels of insulin after birth due to receiving too much gl Continue reading >>

Pregnancy And Gestational Diabetes Screening

Pregnancy And Gestational Diabetes Screening

All pregnant women should be screened for gestational diabetes during their pregnancy. Screening may be done by taking the woman's medical history and examining certain risk factors, but an oral glucose tolerance test is also recommended. The oral glucose tolerance test is used to screen for gestational diabetes. Gestational diabetes is a specific type of diabetes that can develop in some women late in pregnancy (usually after the 24th week). Women who develop this complication do not have diabetes before becoming pregnant. The test is generally given between the 24th and 28th week of pregnancy. If you have had gestational diabetes before, or if your health care provider is concerned about your risk of developing gestational diabetes, the test may be performed before the 13th week of pregnancy. The oral glucose tolerance test involves quickly drinking a sweetened liquid (called Glucola), which contains 50g of glucose. The body absorbs this glucose rapidly, causing blood glucose levels to rise within 30 to 60 minutes. A blood sample will be taken from a vein in your arm about 60 minutes after drinking the solution. The blood test measures how the glucose solution was metabolized (processed by the body). A blood glucose level of 140mg/dL or higher will identify 80% of women with gestational diabetes. When that cutoff is lowered to 130mg/dL, the identification increases to 90%. If your blood glucose level was greater than 130 mg/dL, your provider will likely recommend you take another diabetes screening test that requires you to fast (not eat anything) before the test. During this second test, called the 100-gram oral glucose tolerance test, your blood glucose level will be tested four times during a three-hour period after drinking the sweetened (many flavors are availabl Continue reading >>

Gestational Diabetes

Gestational Diabetes

Gestational diabetes definition and facts Risk factors for gestational diabetes include a history of gestational diabetes in a previous pregnancy, There are typically no noticeable signs or symptoms associated with gestational diabetes. Gestational diabetes can cause the fetus to be larger than normal. Delivery of the baby may be more complicated as a result. The baby is also at risk for developing low blood glucose (hypoglycemia) immediately after birth. Following a nutrition plan is the typical treatment for gestational diabetes. Maintaining a healthy weight and following a healthy eating plan may be able to help prevent or minimize the risks of gestational diabetes. Women with gestational diabetes have an increased risk of developing type 2 diabetes after the pregnancy What is gestational diabetes? Gestational diabetes is diabetes, or high blood sugar levels, that develops during pregnancy. It occurs in about 4% of all pregnancies. It is usually diagnosed in the later stages of pregnancy and often occurs in women who have no prior history of diabetes. What causes gestational diabetes? Gestational diabetes is thought to arise because the many changes, hormonal and otherwise, that occur in the body during pregnancy predispose some women to become resistant to insulin. Insulin is a hormone made by specialized cells in the pancreas that allows the body to effectively metabolize glucose for later usage as fuel (energy). When levels of insulin are low, or the body cannot effectively use insulin (i.e., insulin resistance), blood glucose levels rise. What are the screening guidelines for gestational diabetes? All pregnant women should be screened for gestational diabetes during their pregnancy. Most pregnant women are tested between the 24th and 28th weeks of pregnancy (see Continue reading >>

A Healthier Gestational Diabetes Test Alternative

A Healthier Gestational Diabetes Test Alternative

If you followed along with my last pregnancy, you’ll recall that I was required to consume the neon-orange colored glucose drink (not once, but twice!) to test for gestational diabetes. At the time, it was the only option my doctor would give me, and the way my health insurance worked back then I didn’t have a whole lot of options other than leaving my doctor and opting for a home birth– which we weren’t prepared to do. So I drank the drink and mentally apologized to my growing baby for flooding him with food dyes and preservatives that I would otherwise never consume. What a terrible practice to be forced on so many pregnant women! This time around, I was determined to find a better way. I have a new doctor for this pregnancy, and she knows how I feel about doing things as naturally as possible. (I think it helps that I already have one unmedicated hospital birth under my belt– I feel like doctors believe you more when you have already been through labor.) I told her how terrible my previous glucose testing experience had been, how I received a false positive with the one-hour test, how I felt terrible for nearly a week after my 3-hour test, and how I would really, really, really appreciate another option. And lucky for me, she gave me one. My Alternative Instead of ingesting a corn-derived, artificially-colored drink that I would most likely never consume on a normal basis, I’m simply testing my blood sugar four times a day using a glucose monitor for one week– when I hit the 30-week-mark in my pregnancy. Doesn’t that sound reasonable? What I love about this approach is that I get to see how my body handles the real food I eat on an everyday basis, which seems like it will provide a more accurate result anyway. The only downside is that I hate needles, Continue reading >>

Gestational Diabetes Testing

Gestational Diabetes Testing

Diabetes is a condition in which the body is unable to properly use sugar (glucose) as a source of fuel. As a result, the levels of sugar in the blood become abnormally high. When this condition occurs during pregnancy, it is called gestational diabetes. Gestational Diabetes Impact Gestational diabetes affects about 2–10 percent of all pregnancies. It usually begins in the fifth or sixth month of pregnancy and goes away after the baby is born. Risk factors for gestational diabetes include gestational diabetes in a previous pregnancy, obesity, high blood pressure, increasing age and a close relative with diabetes. Gestational Diabetes Ramifications Gestational diabetes can result in complications for mother and baby. Women with gestational diabetes are more likely to get high blood pressure or pre-eclampsia. They have an increased chance of needing a Cesarean delivery. Babies of women who have gestational diabetes are more likely to develop jaundice. They also may grow too large, leading to an increased risk of birth trauma. Complications can be avoided by controlling gestational diabetes. Gestational diabetes can usually be well controlled through a combination of close monitoring, diet, exercise and occasionally the administration of medication. You will be instructed to go to the lab at your convenience or call to schedule time. The lab will provide the glucose solutions to drink and you will need to remain in the clinic for the duration of the test (about one hour). Gestational Diabetes Screening Test Testing for gestational diabetes is usually done between 24 and 28 weeks of pregnancy. If you have risk factors for gestational diabetes, you may be tested earlier. For accurate results, it is very important that you follow these instructions exactly. You do not need Continue reading >>

Tests & Diagnosis For Gestational Diabetes

Tests & Diagnosis For Gestational Diabetes

When will I be tested for gestational diabetes? Testing for gestational diabetes usually occurs between 24 and 28 weeks of pregnancy. If you have an increased chance of developing gestational diabetes, your doctor may test for diabetes during the first visit after you become pregnant. How do doctors diagnose gestational diabetes? Doctors use blood tests to diagnose gestational diabetes. You may have the glucose challenge test, the oral glucose tolerance test, or both. These tests show how well your body uses glucose. Glucose Challenge Test You may have the glucose challenge test first. Another name for this blood test is the glucose screening test. In this test, a health care professional will draw your blood 1 hour after you drink a sweet liquid containing glucose. You do not need to fast for this test. Fasting means having nothing to eat or drink except water. If your blood glucose is too high—140 or more—you may need to return for an oral glucose tolerance test while fasting. If your blood glucose is 200 or more, you may have type 2 diabetes. Oral Glucose Tolerance Test (OGTT) The OGTT measures blood glucose after you fast for at least 8 hours. First, a health care professional will draw your blood. Then you will drink the liquid containing glucose. You will need your blood drawn every hour for 2 to 3 hours for a doctor to diagnose gestational diabetes. High blood glucose levels at any two or more blood test times—fasting, 1 hour, 2 hours, or 3 hours—mean you have gestational diabetes. Your health care team will explain what your OGTT results mean. Your health care professional may recommend an OGTT without first having the glucose challenge test. Continue reading >>
