Learn about the dangers of gestational diabetes, the factors that contribute to its development, and natural ways to prevent it through lifestyle changes, nutrition and exercise.

Key Takeaway:

• Gestational diabetes mellitus (GDM) is a type of diabetes that occurs during pregnancy, affecting both the mother and the unborn baby.
• Obesity, family history of diabetes and prior instances of GDM are risk factors for gestational diabetes.
• Adopting a balanced diet, avoiding excessive refined carbs and sugary foods, and engaging in low-impact exercise can help prevent gestational diabetes.
• Regular monitoring and consultation with a healthcare team are crucial for effective gestational diabetes management.
• Maintaining a healthy weight and lifestyle, even before pregnancy, can help reduce the risk of gestational diabetes and its complications.

Gestational diabetes mellitus (GDM) is a serious condition that, if not managed properly, can have long-term implications for both mother and baby. This form of diabetes is characterised by high blood glucose levels and occurs during pregnancy, typically between the 24th and 28th weeks of gestation.

GDM occurs when the body cannot produce enough insulin to meet the increased needs of pregnancy, resulting in higher blood sugar levels. Insulin is a hormone that helps the body regulate blood sugar levels by allowing cells to absorb glucose from the bloodstream.

Women diagnosed with gestational diabetes have an increased risk of developing type 2 diabetes, preeclampsia and recurrent gestational diabetes in future pregnancies. Babies born to mothers with gestational diabetes may experience higher birth weights, preterm birth and low blood sugar levels.

Risks for the mother:

• Type 2 diabetes: Women diagnosed with gestational diabetes have an increased risk of developing type 2 diabetes later in life.
• Preeclampsia: Gestational diabetes may increase the risk of preeclampsia, a serious pregnancy complication characterised by high blood pressure and damage to organs such as the liver and kidneys.
• Recurrent GDM: Having gestational diabetes in one pregnancy increases the risk of developing it again in future pregnancies.
• Cardiovascular disease: GDM is associated with a higher risk of cardiovascular disease later in life.

Risks for the baby:

• Higher birth weight: Babies born to mothers with gestational diabetes are more likely to have a higher birth weight, which can increase the risk of birth injuries and complications during delivery.
• Preterm birth: Gestational diabetes may increase the risk of preterm birth, defined as delivery before 37 weeks of pregnancy.
• Low blood sugar: Babies of mothers with gestational diabetes may have low blood sugar (hypoglycaemia) shortly after birth, which can cause seizures and other health problems if not treated promptly.
• Type 2 diabetes: Children born to mothers with gestational diabetes have a higher risk of developing type 2 diabetes later in life.
• Obesity: Children of mothers with GDM are more likely to struggle with obesity throughout their lives.

Prevalence of gestational diabetes

The International Diabetes Federation reports that up to 15% of pregnancies worldwide are affected by gestational diabetes, with variations depending on ethnicity, age and other factors. According to recent research, the rate of gestational diabetes among pregnant Australian women is estimated to be around 14% to 16%. This rate varies based on several factors, including age, ethnicity, lifestyle and diet.

Research suggests that the risk of gestational diabetes increases with age. In Australia, gestational diabetes is more commonly diagnosed in women over the age of 30, with a higher prevalence in women over 40 years old. In fact, approximately 17.9% of women diagnosed with gestational diabetes are aged 30 to 34 years, and the rate increases to nearly 22.1% in women aged 35 to 39 years. For those over 40, the prevalence of gestational diabetes can exceed 27.7%.

Diet and lifestyle

The diet and lifestyle of Australian women also play a significant role in the prevalence of gestational diabetes. Women with less healthy dietary habits and sedentary lifestyles are more likely to develop the condition. Studies have found that the typical Western diet, which is typically high in processed foods, added sugars and unhealthy fats, may increase the risk of gestational diabetes. Additionally, many Australians consume insufficient amounts of fruits, vegetables and whole grains, which are essential for maintaining balanced blood sugar levels.

A sedentary lifestyle, often characterised by prolonged sitting and limited physical activity, can contribute to insulin resistance and increased blood sugar levels. This is particularly concerning for pregnant women, as regular physical activity is crucial for maintaining healthy blood glucose levels and preventing gestational diabetes.

Impact of other factors

It's important to consider the impact of other factors as well, such as obesity, family history of diabetes and prior instances of gestational diabetes, on the prevalence of the condition. Women who are overweight or obese have a higher risk of developing gestational diabetes, as excess body fat can make it harder for the body to use insulin effectively. In addition, a family history of diabetes increases the risk, as genetic factors may contribute to insulin resistance.

Lifestyle modifications to prevent gestational diabetes

Preventing gestational diabetes involves making informed choices and adopting a healthy lifestyle, even before pregnancy. By incorporating balanced nutrition, regular exercise and overall healthy habits, women can significantly reduce their risk of developing gestational diabetes and ensure a healthier pregnancy.

Below are some natural ways to reduce the risk of gestational diabetes.

Balanced diet and nutritional choices

A well-balanced diet plays a crucial role in gestational diabetes prevention. Making healthier food choices not only helps maintain stable blood sugar levels but also supports overall health during pregnancy for both mum and bub.

Here are some dietary recommendations for preventing gestational diabetes:

• Minimise refined carbs and sugary foods: Reduce the intake of refined carbohydrates such as white bread and white rice, which can lead to spikes in blood sugar levels. Avoid sugary drinks like softdrinks (especially caffeinated or energy drinks) and opt for water, herbal teas or natural juices instead.
• Incorporate a variety of fruits and vegetables: Aim for a wide range of fruits and vegetables in your daily meals, as they provide essential nutrients and help balance blood sugar levels.
• Choose whole grains and lean proteins: Opt for whole grains like brown rice, quinoa and whole wheat bread. Include lean proteins like poultry, fish and beans in your diet.
• Consult a professional: Seek advice from a professional dietitian or nutritionist for personalised guidance on blood sugar management and weight gain during pregnancy.

Exercise and physical activity

Regular physical activity is a key component in gestational diabetes prevention. Exercise helps improve insulin sensitivity and regulate blood glucose levels.

Here are some physical activities to consider:

• Walking is a simple and effective low-impact exercise suitable for most pregnant women.
• Swimming provides a full-body workout without putting too much strain on the joints.
• Cycling or stationary biking is a safe option that can help maintain cardiovascular health.
• Yoga offers relaxation, flexibility and strength training.

Consult with your healthcare provider before starting any exercise regimen during pregnancy.

Regular health checkups and monitoring

Regular check-ins with your healthcare team are essential for effective gestational diabetes prevention. Monitoring blood sugar levels throughout pregnancy helps ensure they remain within a healthy range.

Healthy weight management

Maintaining a healthy weight is crucial for preventing gestational diabetes. Excess body fat can make it harder for the body to use insulin effectively, leading to higher blood sugar levels. Consult with your healthcare provider to determine an appropriate weight gain target during pregnancy.

Stress reduction

High stress levels can impact blood sugar levels and contribute to the development of gestational diabetes. Finding natural ways to prevent gestational diabetes may involve stress-reducing activities like meditation, deep breathing and mindfulness.

By maintaining a healthy lifestyle, balanced diet and regular exercise, women can reduce their risk of developing gestational diabetes and ensure a healthier pregnancy.
