Gestational Diabetes: Causes, Symptoms, and Prevention Methods

Pregnancy is a remarkable journey filled with surprises, physical changes, and hormonal fluctuations in the mother’s body. One of these possible changes is the development of gestational diabetes. ________________________________________ What Is Gestational Diabetes? Gestational diabetes is a condition in which blood sugar levels rise during pregnancy in women who were not previously diagnosed with diabetes. It resembles other types of diabetes and can affect both the mother’s health and the baby’s development. It can appear at any stage of pregnancy, but it is most common during the second and third trimesters—usually diagnosed between weeks 24 and 28. The condition occurs when the body does not produce enough insulin, the hormone responsible for regulating blood sugar levels. Fortunately, it can often be managed through a healthy, balanced diet and regular exercise. In some cases, however, insulin injections or oral medications may be required. In this article, we will explore the causes, symptoms, complications, diagnosis, treatment, and prevention of gestational diabetes—along with important tips for expectant mothers. ________________________________________ Causes of Gestational Diabetes The exact cause of gestational diabetes remains unclear. However, research indicates that certain factors—such as being overweight before pregnancy and hormonal changes during pregnancy—can interfere with the body’s ability to regulate blood sugar effectively, leading to elevated glucose levels. ________________________________________ Symptoms of Gestational Diabetes Gestational diabetes often does not cause noticeable symptoms, but some women may experience: • Frequent urination • Excessive thirst • Blurred vision • Nausea • Recurrent infections of the bladder, skin, or vagina ________________________________________ Who Is at Risk for Gestational Diabetes? You are more likely to develop gestational diabetes if you have one or more of the following risk factors: • Insulin resistance prior to pregnancy • Lack of physical activity • Obesity • Previous history of gestational diabetes • Family history of diabetes • Having previously given birth to a baby weighing more than 4.1 kg (9 lbs) • Polycystic Ovary Syndrome (PCOS) ________________________________________ Complications of Gestational Diabetes Gestational diabetes can cause complications that affect both the mother and the baby. Complications for the Mother and Newborn: • Macrosomia (excessive birth weight) • Preterm birth (delivery before the due date) • Breathing difficulties in the newborn, which may become severe • Increased risk of type 2 diabetes in the child later in life • Higher likelihood of childhood obesity • Preeclampsia (high blood pressure during pregnancy) • Stillbirth • Difficult labor or the need for cesarean delivery • The mother may develop type 2 diabetes later in life • High blood pressure threatening the lives of both mother and baby ________________________________________ Risks of Gestational Diabetes 1. Risks for the Mother • Excess amniotic fluid around the baby, which can lead to preterm birth • Heavy bleeding during childbirth • Chronic kidney disease • Fatigue and exhaustion during pregnancy • Possible miscarriage in some cases 2. Risks for the Baby • Poor fetal growth inside the womb • Low calcium levels after birth • Risk of congenital malformations • Weakness and poor vitality at birth These complications highlight the importance of regular monitoring and consulting a doctor if any symptoms appear. ________________________________________ Diagnosis of Gestational Diabetes Gestational diabetes is typically diagnosed between weeks 24 and 28 of pregnancy, although testing may be done earlier if risk factors are present. Diagnosis involves two stages: 1. Screening Test (Glucose Challenge Test) The pregnant woman drinks 50 grams of glucose, and blood sugar is measured one hour later. 2. Oral Glucose Tolerance Test (OGTT) After fasting for 8–14 hours, the woman’s fasting blood sugar is tested. Then she drinks 100 grams of glucose, and blood sugar levels are measured three times, one hour apart. ________________________________________ When Is Blood Sugar Considered High? • Normal fasting blood sugar: 4.0–5.5 mmol/L (72–99 mg/dL) • Two hours after meals: below 7.0 mmol/L (126 mg/dL) If blood sugar exceeds 140 mg/dL after one hour, further testing is required. A reading of 200 mg/dL or higher confirms gestational diabetes. ________________________________________ Treatment of Gestational Diabetes The goal of treatment is to maintain normal blood glucose levels throughout pregnancy. Treatment Methods: • Eating a balanced diet rich in fruits, vegetables, and whole grains • Regular physical activity to improve insulin sensitivity and glucose use • Monitoring blood sugar levels at least four times daily or as advised by your doctor • Insulin therapy may be prescribed if diet and exercise alone are insufficient. The insulin dose should be coordinated with meal plans to prevent low blood sugar. Target Blood Sugar Levels: 1. Fasting glucose: < 95 mg/dL 2. Two hours after meals: < 120 mg/dL 3. HbA1c (average 3-month glucose): < 6.5% ________________________________________ Prevention of Gestational Diabetes While not all cases can be prevented, you can reduce your risk by: • Exercising regularly (walking, yoga, or aerobic activity for 30–40 minutes daily) • Following a healthy, balanced diet, low in sugars and refined carbohydrates, and high in vegetables and fruits rich in fiber • Reaching a healthy weight before pregnancy • Regular prenatal checkups throughout pregnancy to detect any changes early ________________________________________ Tips for Mothers with Gestational Diabetes If you are diagnosed with gestational diabetes, keep these key points in mind: • Take all prescribed medications as directed • Follow a diet plan supervised by a nutrition specialist • Engage in safe, regular physical activity • Avoid sugary foods and beverages • Visit your doctor regularly for monitoring • Get enough rest and maintain good
