Managing Pregnancy with Diabetes: A Complete Guide for Mothers-to-Be

Introduction

You can have a healthy pregnancy even if you have diabetes by maintaining your blood sugar levels during pregnancy within the range your doctor has recommended. This lowers the risk of complications and supports your baby’s growth. Pregnancy can make blood sugar levels harder to manage, whether you have pre-existing diabetes or were diagnosed with the condition during pregnancy. Your doctors may also recommend changes to your treatment plan, including medications and insulin therapy, so you can have a safe pregnancy and a healthy baby.

Understanding Diabetes During Pregnancy

High blood sugar levels either developing or first detected during pregnancy are referred to as gestational diabetes. In this case, insufficient amounts of insulin are produced or used by the body to control normal levels of blood glucose. The placenta produces hormones during pregnancy that naturally cause increased insulin resistance, which helps to provide the growing baby with extra glucose. This is a natural process; however, it may result in constantly elevated blood sugar levels in the case of diabetes.

Before pregnancy diabetes and gestational diabetes are conditions that involve high blood sugar levels; however, the two types of diabetes vary in terms of the factors causing these issues, treatment, and management. Nevertheless, diabetes requires specific care regardless of its type since the level of blood sugar affects the development of your baby. According to research published in the Global LIbrary of Women’s Medicine in 2021, around 16.9% of pregnancies worldwide are affected by high blood sugar in pregnancy.

What Are the Types of Diabetes in Pregnancy

The following are the four types of diabetes in pregnant women:

Type 1 Diabetes with Pregnancy

It happens when your body starts destroying its own cells that make insulin. The condition requires lifelong insulin treatment since your body cannot make insulin. Throughout the pregnancy period, your need for insulin may change, and your doctor may adjust the doses from time to time.

Type 2 Diabetes with Pregnancy

The type of diabetes occurs when your body is either making no insulin or is becoming resistant to it. Most women with type 2 diabetes have healthy pregnancies.

Gestational Diabetes

The condition happens when you develop diabetes during pregnancy if you did not have the condition previously. It usually affects mothers between the second and third trimesters. In some cases, blood sugar may get back to normal after the pregnancy period, but gestational diabetes may raise the chances of getting type 2 diabetes.

Overt Diabetes in Pregnancy

In some instances, blood tests conducted during pregnancy identify that you already had diabetes before you became pregnant. This is referred to as overt diabetes during pregnancy.

How Diabetes Can Affect Pregnancy

Diabetes that is not properly controlled could cause complications during pregnancy or labor for women. It would also complicate other diseases such as those affecting vision or kidneys.

Excess sugar levels in your body would pass through the placenta to your unborn baby’s body, resulting in increased insulin production by your baby’s pancreas. This could affect your baby’s development and cause complications either during pregnancy or later on after childbirth.

What Are the Risks Associated with Pregnancy and Diabetes

Good diabetes management greatly reduces many potential complications for the mother and baby. However, some complications are bound to remain compared to normal pregnancies.

Complications for the Mother

These include:

• Having high blood pressure during pregnancy with diabetes increases the chances of having premature delivery, preeclampsia, and many other complications
• Preeclampsia is a serious complication of pregnancy, manifested through high blood pressure, proteinuria, and even damage to body organs. It normally occurs after 20 weeks of pregnancy or shortly after delivery. 
• Higher chances of having a cesarean delivery 
• Greater chances of infections like Urinary Tract Infections (UTIs) and yeast infections.

Risks for the Baby

Risk factors for the baby in the case of pregnancy with diabetes include:

Excessive birth weight (Macrosomia): The mother's increased level of sugar gets absorbed by the baby and stored as fat, resulting in a baby weighing more than 4,000 gm.

Pre-term Birth: Increased levels of glucose in the mother can lead to conditions such as excess amniotic fluid (polyhydramnios), which can trigger early labor requiring early delivery.

Physical birth injury: Large or heavy babies are prone to shoulder dystocia, due to which the baby's shoulder gets lodged during delivery and can result in physical injuries such as a broken collarbone or even nerve injury.

Low blood sugar after birth: After getting disconnected from the glucose supply from the mother at birth, the baby continues to produce high levels of insulin, which results in a sudden drop in blood sugar levels in the baby.

Breathing problems: High levels of insulin and preterm birth can result in delayed development of lungs and breathing problems, for example, respiratory distress syndrome in the baby.

How to Plan for Pregnancy When You Have Diabetes

If you have diabetes and you’re planning a pregnancy, preparing beforehand can keep both you and your baby healthy and safe.

In preconception counselling, your healthcare provider may:

• Review your diabetes or blood sugar control
• Review any existing medical conditions
• Assess your kidney and eye health
• Recommend folic acid supplements 
• Discuss how pregnancy may affect your blood sugar and overall diabetes management

Achieving your target blood sugar levels can help you reduce the risk of miscarriage and other birth defects. 

Though some medications for blood pressure, diabetes, or cholesterol may not be suitable, you should never discontinue or change any medicines without your doctor’s advice.

Healthy habits even before conception can help ensure a safe pregnancy. You should focus on these things:

• Exercise and stay physically active
• Eat a healthy and balanced diet
• Avoid foods with high sugar levels
• Get enough sleep
• Maintain a proper weight
• Avoid alcohol and smoking 

How to Manage Blood Sugar During Pregnancy

Here are some effective ways to manage your blood sugar levels during pregnancy:

Blood Glucose Monitoring

Check your blood sugar before meals, one or two hours after meals, at bedtime, and at other times when your healthcare providers may recommend. Or, you can also use a continuous glucose monitor (CGM) to track glucose levels throughout the day. 

Target Blood Sugar Levels

Though you should follow levels recommended by your doctor, common recommendations for pregnancy are:

Importance of Regular Medical Check-Ups

If you are pregnant and you have diabetes, you'll need regular health check-ups to monitor your glucose levels. They can help you track fetal growth and prevent serious complications like preterm labor or high birth weight. 

Monitoring HbA1c During Pregnancy

If you have preexisting diabetes and you're pregnant, the recommended target for HbA1c is 6.0. However, you should track blood sugar daily because pregnancy can alter red blood cell turnover and make HbA1c less reliable over time. 

Diet and Nutrition for Pregnancy with Diabetes

A healthy pregnancy diet for diabetes should focus on balanced meals, portion control, and managed carbohydrate intake.

Why Diet Matters

It matters for pregnancy with diabetes because healthy eating can:

• Most importantly, improve blood sugar control
• Promote healthy pregnancy weight gain
• Support your baby’s growth
• Reduce the need for additional medications in some cases

The table below includes the foods you should eat and the ones you need to limit or avoid:

Meal Planning Tips

Here are some points you should remember:

• Spread carbohydrates evenly
• Never skip meals
• Pair carbs with protein and healthy fats
• Opt for eggs, whole grain toast, etc., for breakfast, instead of cereals and fruit juices
• Drink a lot of water
• Include non-starchy vegetables in all meals
• Follow portion advice from your dietitian 

Healthy Snack Options

Some healthy snack options you can include in your diet are:

• Roasted chickpeas
• Some nuts
• Unsweetened yogurt or Greek yogurt with berries 
• Apple slices with some peanut butter
• Whole-grain crackers
• Hard-boiled eggs
• Steamed or roasted soybeans

Managing Carbohydrate Intake

Carbohydrates remain an important part of a healthy pregnancy. To maintain steady blood sugar levels, choose high-fibre carbohydrates and spread them evenly across meals. 

Exercise and Physical Activity During Pregnancy

Exercise during pregnancy helps you stay active, improve blood sugar control, boost your mood, ease back pain and constipation, and build stamina for childbirth.

Some physical activities generally considered safe for pregnancy include:

• Walking
• Swimming
• Prenatal yoga
• Modified strength training
• Bird dog and squats
• Gentle stretching
• Low-impact aerobics

Stay hydrated and don’t overheat yourself. If you experience severe pain, dizziness, reduced fetal movements, or bleeding, stop exercising immediately. 

You should stop exercising immediately if you experience:

• Fluid leaking or vaginal bleeding
• Dizziness, severe headaches, feeling faint
• Extreme shortness of breath or chest pain
• Regular and painful contractions of the uterus
• Calf pain, swelling, or sudden muscle weakness

You should avoid exercising in case of placenta previa and high blood pressure. 

Medications and Insulin Therapy During Pregnancy

Insulin is the preferred treatment for diabetes during pregnancy because it effectively controls your blood sugar levels. It can help keep both the mother and the baby safe.

Your doctors may continue some of the oral medications you may be taking to manage diabetes during pregnancy, while they may replace others with insulin.

Your doctor can adjust insulin doses or medications based on how your pregnancy progresses and changes in pregnancy hormones.

Medical supervision is important for medications and insulin therapy to properly manage diabetes during pregnancy because changing hormone levels can quickly alter your insulin resistance. 

What Are the Common Pregnancy Complications Linked to Diabetes

Here are some common complications associated with pregnancy affected by diabetes:

Preeclampsia

It’s a serious pregnancy complication marked by high blood pressure, protein in the urine, or even signs of organ damage. Usually, it starts after 20 weeks of pregnancy

Polyhydramnios

This is a medical condition in which there is too much amniotic fluid around the baby during pregnancy. High blood sugar can lead to excess amniotic fluid, increasing the risk of preterm labor.

Preterm Labor

Poorly managed diabetes can increase the risk of preterm labor. This means you can go into labor or need a delivery before 37 weeks of gestation.

Fetal Growth Concerns

High blood sugar can cause the baby to grow larger and heavier than average for their gestational age. If there are underlying vascular issues, it can also restrict fetal growth, with the baby being smaller than expected for their gestational age.

Delivery Complications

If the baby is larger than usual, it can increase the chances of a difficult delivery or the need for a cesarean.

Labor and Delivery Considerations

Your diabetes plan will not depend on diabetes alone. Instead, it will depend on your overall pregnancy and your baby’s health. Once active labor begins, your blood sugar levels are monitored every hour during labor to keep glucose in a safe target range.

The optimal timing of delivery for pregnancies affected by diabetes generally occurs during the 39th week of gestation for well-controlled diabetes cases. However, it can happen earlier for women with poorly controlled diabetes or high blood sugar.

Many pregnant women with diabetes have normal, vaginal deliveries, but your doctors may recommend a cesarean section based on your health and your baby’s size and other factors.

Care After Delivery

After delivery, your body will adjust to changing hormones and blood sugar levels, and that’s why your diabetes care should continue.

Blood sugar can often change quickly after childbirth. If you have pre-existing diabetes, you may need lower insulin and medication doses, but if you were diagnosed with gestational diabetes, glucose levels may return to normal after childbirth.

Breastfeeding is safe and highly beneficial for mothers with diabetes and their babies, but careful blood sugar monitoring is required. It can help lower maternal insulin needs, protect your baby against future health risks, and can temporarily delay milk production.

In a postpartum checkup, especially if you have gestational diabetes, doctors will check your glucose levels, review your medications, and perform ongoing diabetes screening and an oral glucose tolerance test

Maintain a healthy diet after childbirth and exercise regularly. Also, attend regular health checkups, and if you're planning future pregnancies, consult with your healthcare provider to lower your risk of diabetes in the long run.

Tips for a Healthy Pregnancy with Diabetes

Here are some effective tips to ensure a healthy pregnancy with diabetes:

• Monitor your blood sugar levels during pregnancy.
• Carefully follow your prescribed treatment plan.
• Perform exercises safe for pregnancy.
• Eat a balanced diet. 
• Even if you feel perfectly well, attend every prenatal appointment.
• If you feel overwhelmed, seek support from your family, support groups, or healthcare team.

Conclusion

A diagnosis of diabetes before or during pregnancy can make you feel overwhelmed, but it does not mean you can’t have a normal, healthy pregnancy. You can manage diabetes during pregnancy through regular checkups, appropriate treatment, healthy lifestyle choices, eating a balanced diet, and regular exercise. You shouldn’t aim for perfect blood sugar levels every day. Instead, you should focus on following your care plan, and if you notice abnormal changes in your blood sugar or pregnancy symptoms, talk to your doctor immediately. They can help you plan and manage your pregnancy better and take care of yourself after childbirth.
