How is gestational diabetes mellitus diagnosed?

The following tests can be performed to diagnose gestational diabetes.

  • Initial glucose challenge test: 

A blood sugar level of 190mg/dl, (10.6mml/l) indicates gestational diabetes. A blood sugar level below 140mg/dl (7.8mml/l) is considered normal.

  • Glucose tolerance test (a follow-up test).

Treatment includes:

  • Lifestyle changes: how a pregnant female eats and moves. 
  • Blood sugar monitoring: by glucose level testing.
  • Medication (if necessary): insulin injection, oral drugs.

Life Changes Healthy diets

The mother is advised to take food that is high in nutrition and fiber and low in fat and calories, such as fruit, vegetables, whole grains, and lean protein. Avoid highly refined carbohydrates, including sweets. 


 Housework, gardening, walking, and light exercise.


How early can gestational diabetes be diagnosed?

Gestational diabetes usually does not occur until late in pregnancy, when the placenta produces more of the hormones that interfere with the mother’s insulin. Screening for diabetes in pregnant women takes place between weeks 24 to 28, but women at high risk are likely to be screened in the first 3months 

Can a blood test detect gestational diabetes?

Symptoms of gestational diabetes, in most cases, are not prominent. Most cases are only detected when the blood sugar level is tested during screening for gestational diabetes.

Is gestational diabetes considered high-risk pregnancy? 

Gestational diabetes increases the risk of high blood pressure and preeclampsia, a serious complication of pregnancy that causes high blood pressure and other symptoms that can threaten the lives of both mother and baby. 

What are the warning signs of gestational diabetes?

a)       Sugar in the urine 
b)       Unusual thirst 
c)       Frequent urination 
d)       Nausea
e)       Blurred vision 
f)        Fatigue 
g)       Vaginal, bladder, and skin infection.

3)       Race: American Indians, Hispanics, Asian Americans, African
4)       Hereditary
5)       History of GDM during a previous pregnancy

9)       Females who conceive at a late age (>35years)
10)   Give birth to babies who are stillborn, dead, or born with birth defects.

What are the neonatal complications associated with GDM mothers?

The neonatal complications are:
1)       Macrosomia (large-size baby)
2)       Hypoglycemia which is a low blood sugar level in the baby within a few hours of delivery.
3)       Respiratory distress syndrome
4)       Early birth of the child (preterm baby)

Can GDM be prevented?

There is no guarantee when it comes to preventing gestational diabetes. However, there are a few measures that a mother can follow to minimize the risk of developing type 2 DM or having GDM in future pregnancies. They are listed below:
1)       Avoid being obese or overweight before pregnancy
2)       Maintain a healthy lifestyle and diet plan
3)       Exercise regularly 
4)       Eat healthy food
5)       Maintain the weight throughout pregnancy
6)       Don’t gain more weight than recommended

How common is gestational diabetes mellitus worldwide?

The incidence of GDM is becoming high over time due to a lack of maintenance of healthy life or living a poor quality of life. It is estimated that about 7-10% of all pregnancies are affected by GDM worldwide [1]. 

Will gestational diabetes go away after delivery?

In most cases, the blood glucose level comes down on its own after delivery. However, 50% of the women diagnosed with GDM might develop type 2 DM later in life. Maintaining a healthy diet and weight and exercising daily can help in decreasing the risk of developing DM in the future.

What is the recovery period or healing time of GDM?

The recovery period of GDM varies from person to person, their severity, and depends on the type of treatment adopted.
