Gestational Diabetes Mellitus: All You Need to Know

Summary: Gestational diabetes mellitus is a condition that affects pregnant women, causing high blood sugar levels due to hormonal changes that interfere with insulin function. It is diagnosed through routine screenings between the 24th and 28th weeks of pregnancy, and early detection is important to reduce risks. The condition is usually managed through lifestyle changes such as a balanced diet, regular exercise, and monitoring blood sugar levels. 

Pregnancy is a life-changing journey, but it can bring unexpected challenges, like gestational diabetes mellitus (GDM). This is a temporary form of diabetes that arises during pregnancy when the body cannot produce enough insulin to regulate blood sugar levels effectively. Although it typically resolves after childbirth, proper management during pregnancy is crucial to ensure the health and safety of both mother and baby.

To help you understand this condition better, the best gynecologist doctor in Gurgaon at Miracles Apollo Cradle shares insights into its causes, symptoms, risks, and management strategies.

What Is Gestational Diabetes?

Gestational diabetes or glucose intolerance or carbohydrate intolerance, is a temporary condition that occurs only during pregnancy. It develops when pregnancy-related hormones interfere with insulin function, leading to higher-than-normal blood sugar levels. Pregnant mothers undergo routine screening for gestational diabetes between the 24th and 28th weeks of pregnancy. Timely diagnosis allows for proper treatment, ensuring a healthy pregnancy and delivery.

Gestational Diabetes Mellitus Causes

  • Hormonal Changes: The placenta produces hormones to support the growth of the baby. Some of these hormones, like human placental lactogen (HPL), counteract insulin, leading to insulin resistance.

  • Increased Demand on the Pancreas: As the baby grows, the body needs more insulin.  When the pancreas cannot meet this increased demand, blood sugar levels rise, causing gestational diabetes.

These changes generally become more prominent in the later stages of pregnancy, making gestational diabetes more common during the second and third trimesters.

Gestational Diabetes Mellitus Signs and Symptoms

Gestational diabetes usually has no noticeable symptoms, which is why routine testing is necessary. However, in some cases, women may experience:

  • Excessive thirst

  • Dry mouth

  • Frequent urination

  • Feeling fatigued

  • Blurred vision

  • Nausea

  • Recurrent infections of the skin, bladder, or vagina

If you notice any of these signs, consult your gynecology immediately for evaluation and guidance.

Gestational Diabetes Mellitus Risk Factors

While gestational diabetes can affect any pregnant woman, several factors can increase the risk of developing the condition. Understanding these risk factors of gestational diabetes mellitus is essential for early detection and management:

  • Obesity (High BMI): Women with a body mass index (BMI) of 30 or higher are at higher risk of developing gestational diabetes.

  • Family History of Diabetes: If you have a family history of diabetes, especially Type 2 diabetes, you may be more likely to develop gestational diabetes.

  • Previous Gestational Diabetes: If you had gestational diabetes in a previous pregnancy, you are at a higher risk of developing it again.

  • Ethnicity: Certain ethnic groups, such as Hispanic, African American, Native American, and Asian, are more likely to develop gestational diabetes.

  • Age: Women who are over the age of 25, especially those in their 30s or older, are at higher risk.

  • High Blood Pressure (Hypertension): Preexisting or pregnancy-related hypertension increases the risk.

  • Polycystic Ovary Syndrome: Females with PCOS have a higher chance of developing gestational diabetes mellitus.

  • Previous Large Baby: If you’ve had a baby weighing more than 4.5 kg (9 lbs) in a previous pregnancy, you may be at risk.

  • Multiple Pregnancies: Carrying twins or multiples increases the likelihood of developing gestational diabetes.

Gestational Diabetes Mellitus Diagnosis

Timely diagnosis is important to managing gestational diabetes effectively. Here is how it is diagnosed:

  • Routine Screening: Most pregnant women undergo screening for gestational diabetes mellitus between 24 and 28 weeks. However, those at higher risk may be screened earlier.

  • Glucose Challenge Test (GCT): This is a preliminary test where you drink a glucose solution, and your blood sugar levels are measured an hour later. If the results of the GCT are higher than normal, further testing is done.

  • Oral Glucose Tolerance Test (OGTT): This confirmatory test involves fasting overnight, followed by drinking a glucose solution. Blood sugar levels are tested multiple times over three hours to assess how your body processes glucose.

Your gynaecologist will recommend these tests based on your health history and risk factors.

Why Early Detection Matters?

Gestational diabetes mellitus, if left unmanaged, can lead to complications such as:

  • Premature birth

  • Stillbirth 

  • Neonatal death

  • Excessive birth weight

  • Cesarean delivery

  • Future diabetes risk to mother and child 

With early diagnosis and proper management, these risks can be reduced, ensuring a healthier pregnancy and delivery.

Gestational Diabetes Mellitus Treatment

The goal of treatment is to maintain healthy blood sugar levels to protect the mother and baby. Gestational Diabetes Mellitus Treatment involves a combination of lifestyle changes and, in some cases, medication.

Healthy Eating

  • Focus on a balanced diet that is rich in whole grains, vegetables, lean proteins, and healthy fats.

  • Avoid sugary snacks and processed foods.

  • Eat smaller meals throughout the day to stabilize the level of blood sugar.

Regular Exercise

  • Gentle exercises like walking, swimming, or prenatal yoga can improve insulin sensitivity.

  • Consult your gynecologist before starting any new physical activity.

Monitoring Blood Sugar Levels

  • Keep track of your blood sugar levels regularly to ensure they remain within the target range.

  • Medication if Necessary

  • If diet and exercise are not enough, your gynecologist may prescribe insulin or other medications to control your blood sugar level.

Regular Check-Ups

  • Frequent prenatal visits are important to monitor the mother's and baby’s health.

Can Gestational Diabetes Be Prevented?

While it is not always possible to prevent gestational diabetes, maintaining a healthy lifestyle before and during pregnancy can remarkably reduce your risk.

  • Achieve a Healthy Weight: Start your pregnancy at a healthy BMI.

  • Eat a Balanced Diet: Focus on nutrient-rich foods and limit added sugars.

  • Stay Active: Regular physical activity before and during pregnancy improves insulin sensitivity.

Conclusion:

Gestational diabetes is a manageable condition with timely intervention and the right care plan.
