If you’ve been diagnosed with gestational diabetes, you’ve likely got a lot on your mind. Not only are you navigating pregnancy and preparing for parenthood, but you’re also concerned about how this condition may affect your health and the health of your baby.

Gestational diabetes isn’t something to be taken lightly. It can lead to preterm delivery and respiratory distress syndrome in babies and can cause preeclampsia and future metabolic issues (like type 2 diabetes) in moms.1 Fortunately, most cases of gestational diabetes can be managed with lifestyle changes in areas like exercise, stress, and, most importantly, diet. In this article, we’ll explain what you need to know about gestational diabetes and provide a sample meal plan.


Understanding Gestational Diabetes

Gestational diabetes is one of the most common conditions associated with pregnancy. An estimated 8% of mothers are diagnosed with gestational diabetes, and this risk increases to almost 16% in mothers over the age of 40.2 

Gestational diabetes occurs when your pancreas can’t make enough insulin to keep up with the new demands associated with pregnancy. Although this condition typically subsides after you give birth, it can lead to complications like high blood pressure and type 2 diabetes for the mom and other serious health concerns for the baby.3

During pregnancy, your baby requires lots of fuel (in this case, glucose) because they are growing so quickly.  To accommodate this increased need, your body changes how it handles glucose. During pregnancy, your body produces hormones like progesterone, cortisol, and prolactin, making your cells more insulin-resistant.3 This decrease in maternal insulin sensitivity saves glucose molecules so they can be transferred through the placenta to the baby. 

As the mother’s cells become more insulin-resistant, the pancreas is required to produce more insulin. If the pancreas can’t keep up with the increased demand for insulin, gestational diabetes develops. Although this condition can’t be reversed, it can be properly controlled with the right diet.

Tips for Maintaining Low Glucose Levels When Pregnant

Keeping your blood sugar levels in check is always important, but this becomes your highest priority if you have gestational diabetes. Here are some of the best ways to balance your blood glucose levels during pregnancy.

  1. High Fiber: The American Pregnancy Association recommends aiming for 25 to 30g of fiber per day.4 Fiber helps slow down the absorption of glucose, which will prevent your blood sugar from spiking. Fiber also supports a healthy gut microbiome, which has been shown to improve glucose control in people with type 2 diabetes.

  2. Stay Physically Active: The easiest thing you can do to lower your blood sugar is to get moving, and this has never been more true than during pregnancy. Studies have shown that exercise during pregnancy has been shown to decrease the risk of gestational diabetes.6

    Traditional exercises like running and weight lifting can feel difficult during pregnancy with all the changes your body is going through (especially in the third trimester), but any type of physical activity will help. Low-intensity exercises like yoga, swimming, dancing, and even walking can lead to a healthier pregnancy and delivery.

  3. Manage Stress:Stress hormones can cause a rise in blood sugar, so it’s important to do your best to manage your stress levels while pregnant. Pregnancy can be very stressful as your mind and body adapt to many changes, so it’s essential to find ways to actively relax. Things like breathwork, meditation, journaling, or even listening to music can help you unwind.

  4. Monitor Your Blood Sugar Levels Regularly: If you’ve been diagnosed with gestational diabetes, it’s crucial to monitor your blood sugar levels frequently to prevent any major swings. Continuous Glucose Monitors (like the one Signos offers) are painless, convenient, and give you real-time data to keep your blood sugar in check.

Managing Gestational Diabetes Through a Healthy Diet

Your diet plays a big role in your body’s glucose metabolism and insulin production, which is why it’s so important to be mindful of what you’re eating when you're pregnant. Eating a balanced diet high in fiber, high-quality protein, and healthy fat can support a healthy pregnancy and prevent health complications for you and your baby. 

Below are our top tips for how to improve your diet when you have gestational diabetes:

  1. Eat Balanced Meals: Although it may feel easy to give in to cravings, avoid high-carbohydrate meals and snacks. Instead, balance carbohydrate-rich foods with lean protein, fat, and fiber. Instead of a bowl of mac & cheese, try mac & cheese with chicken and broccoli. Instead of a chocolate bar, try unsweetened Greek yogurt with chocolate chips and nuts. Eating this way will slow down digestion and help flatten your blood sugar curve.

  2. Opt for Complex Carbohydrates: Simple carbs like white bread, traditional pasta, cookies, cakes, chips, and candy are quickly broken down and absorbed by the body, which will send your blood sugar soaring. Instead, choose complex carbohydrates like whole grain bread and cereals, chickpea or lentil pasta, and sweets packaged with fiber like fruit.

  3. Maintain Regular Eating Intervals Throughout the DayEating at regular times during the day can help prevent high blood sugar and low blood sugar swings. This will also help you maintain your energy levels (pregnancy fatigue is real) and support regular bowel movements.
