Pregnancy Diabetes Calculator

The Pregnancy Diabetes Calculator is designed according to World Health Organization (WHO) guidelines, aiming to identify gestational diabetes—a form of diabetes that develops temporarily during pregnancy. All women who are pregnant should get tested to rule out the possibility of diabetes.

Gestational diabetes affects 14 -17% of pregnant women worldwide. The Pregnancy Diabetes Calculator is designed according to World Health Organization (WHO) guidelines, aiming to identify gestational diabetes. All women who are pregnant should get tested to rule out the possibility of diabetes.

What is Gestational Diabetes?

Gestational diabetes or pregnancy diabetes is a condition that develops due to insulin resistance during pregnancy lead to high blood sugar levels. Gestational diabetes develops due to hormones produced by the placenta. This is a temporary condition that resolves once the baby is born but it can manifest as type 2 diabetes later in life. It is usually diagnosed during the 24th to 28th week of pregnancy (1).

How does Gestational Diabetes Affect the Baby?

High blood glucose levels during pregnancy especially in conditions like gestational diabetes can cause complications for both the mother and the child. The effects it has on the child are as follows:

  1. Premature Birth: High blood sugar can lead to preterm birth or being born too early. Premature babies often face health problems due to underdeveloped organs.
  2. Large baby: Increased blood glucose can result in a baby growing too large known as macrosomia. This makes childbirth difficult and increases the risk of birth injuries. This often leads to birth by cesarean section or C-section.
  3. Low Blood Sugar: After birth, babies born to mothers with high blood glucose levels may experience hypoglycemia or low blood sugar. This is because the baby’s body produces more insulin in response to high blood sugar in the womb and it is difficult to regulate blood glucose levels.
  4. Respiratory Problems: High blood glucose levels can delay the development of lung functioning in babies which can lead to breathing problems .
  5. Stillbirth: elevated blood glucose levels can increase the risk of miscarriage or stillbirth if the condition is poorly managed.
    Babies are more likely to develop obesity and type 2 diabetes later in life (2).

Effect of Gestational Diabetes on Mother

Gestational diabetes can lead to the development of the condition called pre-eclampsia which is characterized by high blood pressure and protein in the urine.

Cesarean section or C-section birth may be indicated if the child is large or overweight.

They have a higher risk of developing type 2 diabetes later in their life.

High blood sugar can cause diabetic retinopathy , heart disease, kidney disease and nerve damage (3).

How to Test for Diabetes in Pregnancy

The primary test for diagnosing gestational diabetes is the Oral Glucose Tolerance Test (OGTT). Here's how it works:

  1. You will need to fast (avoid eating or drinking anything except water) overnight before the test.
  2. At the diagnostic lab, the fasting glucose level will be measured with blood samples.
  3. You’ll be asked to drink a sweet liquid containing 75 grams of glucose.
  4. After two hours another blood sample is taken to check post-glucose blood sugar levels.
The general glucose ranges according to WHO (World Health Organization) guidelines for diagnosing and managing gestational diabetes:

Fasting Blood Sugar:

  • Normal: Less than 5.1 mmol/L (92 mg/dL)
  • Gestational Diabetes: 5.1 mmol/L (92 mg/dL) or higher

2-Hour Post-Glucose Drink (Oral Glucose Tolerance Test):

  • Normal: Less than 8.5 mmol/L (153 mg/dL)
  • Gestational Diabetes: 8.5 mmol/L (153 mg/dL) or higher (4)
If you have a family history of type 2 diabetes, you have a higher chance of developing gestational diabetes. As it was mentioned, having gestational diabetes increases your risk of developing type 2 diabetes later in life, hence maintaining a healthy lifestyle after pregnancy can help reduce this risk.

Diet Tips for Gestational (Pregnancy) Diabetes:

A woman with Gestational (Pregnancy) Diabetes needs to follow a healthy diet plan and keep her blood sugar (glucose) level under control.
  • Consume fat and protein in moderate amounts. Good sources of protein include meat, fish, dry beans, eggs, and nuts.
  • Whole fruits are a healthier option than fresh juices which can a rapid sugar spike in the blood.
  • Carbohydrates should make up less than half of your daily calories. Opt for sugar-free treats and avoid high-sugar foods.
  • Reduce foods like hamburgers, cheese, and processed meats that are high in saturated fats.
  • Small, balanced meals spaced evenly throughout the day help to maintain stable blood sugar levels.
  • Choose whole grains (such as brown rice, whole wheat bread and oats) instead of refined grains.
  • Drinking plenty of water helps your body function optimally and can also help reduce cravings for sugary drinks (5).
Don't hesitate to reach out to your doctor, a registered dietitian, or a diabetes educator for guidance and support throughout your pregnancy.

FAQs

1. Which doctor should I visit for gestational diabetes?

You should initially consult with your obstetrician (OB-GYN) for gestational diabetes management. Depending on your specific needs, they may also refer you to other specialists such as an endocrinologist for further guidance and treatment.

2. Why is testing blood sugar important in pregnancy?

Without specific testing, gestational diabetes can often go undetected until complications arise. The symptoms and signs of diabetes may be subtle such as excessive thirst, increased urination , and unusual tiredness. Monitoring helps manage blood sugar levels, reducing the risk of these complications and ensuring a safe pregnancy and delivery. It also lowers the long-term risk of type 2 diabetes for the mother (4).

3. Will I require insulin jabs to control my sugar?

Yes, in some cases, insulin injections may be required to control blood sugar levels if diet and lifestyle changes are not enough. This helps prevent complications for both the mother and baby, ensuring a healthier pregnancy (1).

4. What percentage of women with gestational diabetes will have diabetes after the pregnancy?

The blood sugar levels will return to normal after delivery. Approximately 50% of women who have developed gestational diabetes will develop type 2 diabetes within 5-10 years after pregnancy. Regular monitoring and a healthy lifestyle can reduce the risk.

5. Does ethnicity play a role?

Yes, Ethnicity plays a major role in gestational diabetes. This could be due to a variety of factors, including genetic predisposition, lifestyle factors, and socioeconomic factors. Women of the following ethnic groups have higher chances of having gestational diabetes:

  • African Americans
  • Hispanic or Latino Americans
  • American Indians
  • South Asian(7)

6. What are the symptoms of gestational diabetes?

Gestational diabetes often manifests without noticeable symptoms, highlighting the importance of testing for early detection and management. However, when symptoms do appear, they can include increased thirst, frequent urination, dry mouth, fatigue, blurred vision, or genital itching or thrush (8).

7. Can exercise help control gestational diabetes?

Yes, regular exercise helps your body use insulin more effectively, keeping blood sugar levels in check. Regular physical activity such as swimming, walking or prenatal yoga can lower blood sugar levels improving overall health and reducing the risk of complications during pregnancy. Always consult with a healthcare provider before starting an exercise routine to ensure it's safe for both you and your baby (9).

8. Can I still eat sweets if I have gestational diabetes?

Yes, you can still enjoy sweets in moderation if you have gestational diabetes, but it's important to be mindful of portion sizes and how they affect your blood sugar. Opt for sugar-free or low-glycemic alternatives when possible, and try to pair sweets with a source of protein or healthy fat to help balance blood sugar levels (10).

9. Is breastfeeding safe with gestational diabetes?

Yes, breastfeeding is safe and highly beneficial for both mother and baby, even if the mother had gestational diabetes. Breastfeeding helps regulate the baby's blood sugar levels, reduces the risk of obesity and diabetes later in life, and promotes bonding.

For the mother, breastfeeding can assist in regulating blood sugar and may help in losing pregnancy weight. However, mothers with gestational diabetes need to continue monitoring their blood sugar levels while breastfeeding, as breastfeeding can influence insulin needs. Always consult with a healthcare provider for personalized advice (11).
