What is Gestational Diabetes: Gestational Diabetes Mellitus (GDM) is a condition wherein a high blood sugar level is present in the mother during pregnancy. Pregnant women are often screened for gestational diabetes in the latter part of their second trimester as a standard obstetrical practice.
The United for Diabetes Philippines 2011 report states that gestational diabetes mellitus complicates at least 14% of pregnancies. If left unmanaged, it has the potential to harm both mother and child.
What is gestational diabetes?
Gestational diabetes refers to a condition where the body cannot produce the needed insulin during pregnancy. If you are an expectant mom and you have this condition, you are most likely at risk to develop high blood sugar levels during pregnancy. Gestational diabetes usually disappears after giving birth.
It is important that this condition is detected early to manage it before getting worse and to prevent other complications in pregnancy. Gestational diabetes may cause a problem for both the mom and the baby.
This condition typically occurs between the 24th to 28th weeks, so, it’s important to monitor your blood sugar level during this time of pregnancy.
According to Healthline, having gestational diabetes during pregnancy may raise your risk of developing type 2 diabetes in the future. In addition, gestational diabetes if left untreated, can also raise your baby’s chance of developing diabetes. It may also pose a risk of experiencing complications during pregnancy and delivery.

Causes of Gestational Diabetes
What are the causes of gestational diabetes? Weight gain during pregnancy is frequently a factor. Several hormones typically regulate blood sugar levels.
However, the body has a harder difficulty adequately digesting blood sugar during pregnancy due to changing hormone levels. A blood sugar rise result from this.

Any pregnant woman who has new or unusual symptoms should consult their physician. If she has developed GDM or any other disease, the doctor may be able to tell more accurately. Thus, giving proper medication and treatment as well.
Most symptoms of gestational diabetes are similar to normal pregnancy symptoms. That is why it is essential to consult your doctor if there’s any sign or symptom that brings you to worry.
Risks on baby
The mother’s inability to produce the right amount of insulin during pregnancy puts the baby at risk in many ways. If GDM presents in the first trimester, this may mean birth defects affecting major organs or an increased risk of miscarriage.
According to the National Health Service UK website, the following may occur when GDM is observed in the second or third trimester:
- Macrosomia – The fetus grows so big (8 pounds and above) that its presents problems during labor and delivery. This may result in shoulder dystocia or other birth injuries as well as increased risks for cesarean delivery.
- Hypoglycemia – While a low blood sugar level in the baby is pretty common in newborns for the first two hours or so after birth, an extended period in this condition may result in neurological problems, developmental delays, and seizures.
- Jaundice – Baby’s skin and eyes are yellow. Though common in newborns, especially among Asian babies, and does not usually indicate a problem, jaundice remains a cause for concern for medical practitioners since it can potentially result in neurological, behavioral, and developmental issues.
- Respiratory Distress Syndrome (RDS) – A baby has trouble breathing and may need medical intervention.
Risks on mother
According to mayoclinic.com, the following conditions may occur in mothers with GDM:
- High blood pressure, preeclampsia, and eclampsia – The latter two cause high blood pressure. All 3 pregnancy complications can pose a fatal threat to mom and baby.
- Future diabetes – Gestational diabetes has a great chance of occurring in the next pregnancy. The mother is also likely to develop type 2 diabetes as she gets older.
How is it diagnosed?
It is highly encouraged by professionals that pregnant women routinely undergo screening for any signs of gestational diabetes. According to Healthline, if a woman has no history of diabetes and has optimal blood sugar levels at the beginning of pregnancy, then her healthcare provider will most likely order a gestational diabetes screening when she is 24 to 28 weeks pregnant.
Here are some tests that your doctor may recommend you to rule out gestational diabetes:
Oral glucose challenge test
In doing an oral glucose challenge test, you need to drink a glucose solution, first. Your blood will be tested after an hour. If the result of your blood test shows that you have a high level of blood sugar then your healthcare provider may perform a 3-hour oral glucose tolerance. In addition, this process is also known as two-step testing.
However, there are doctors who skip the glucose challenge test and perform the 2-hour glucose tolerance test instead. This process is considered one-step testing.
What are 1-step and 2-step testing?
In one step test, you need to fast before your blood is tested. Your doctor will start testing your fasting blood sugar levels. Next, you will ask to drink a solution with 75 grams of glucose. Afterward, your blood sugar levels will be tested again after 1 hour and 2 hours.
On the other hand, in a 2-step test, you are not required to fast. And instead of drinking a solution with 75 grams of glucose, your healthcare provider will ask you to drink a solution containing 50 grams of sugar. Afterward, they will test your blood sugar after an hour.
Treatment of Gestational Diabetes
Catching and managing the condition early during pregnancy will help avoid complications. A mother will have to be monitored closely. A physician may insist on a regular glucose tolerance test from when the condition is diagnosed to close to birth.
Treatment of gestational diabetes: Gestational diabetes diet
The right diet and exercise will keep GDM from getting worse, but so will controlling the weight gain of the baby inside. Medications may be necessary to control insulin levels and avoid further complications like preeclampsia.
In cases of neonatal hypoglycemia, immediate and proper breastfeeding is encouraged. In cases where this might not be possible, glucose water is sometimes given to newborns.
Treatment of jaundice also requires a mother to breastfeed more since breastmilk has laxative properties that facilitate the excretion of bilirubin.
It has to be stressed that most IDMs (infants of diabetic mothers) grow on to become healthy babies. However, to reduce the risks of their children growing up obese or developing Type 2 Diabetes, decisions on child feeding, lifestyle, and habits should be made a priority by mothers with gestational diabetes.
