Gestational diabetes (GD) is a unique form of diabetes that develops during pregnancy, affecting how your body uses sugar, and is typically identified in the second or third trimester. It’s a condition that many pregnant people encounter, with evidence suggesting it affects a notable percentage of pregnancies in the US, and rates can vary depending on the population and how it's diagnosed.

## What it is

GD occurs when your body doesn't produce enough insulin or can't effectively use the insulin it makes during pregnancy. This leads to higher-than-normal blood sugar levels. While it usually resolves after birth, it's important to manage it carefully during pregnancy to support both your well-being and your baby's development. Universal screening for GD is a standard practice in many countries, including the US, UK, Canada, and Australia, typically occurring between 24 and 28 weeks of pregnancy through a glucose challenge test. It's worth noting that diagnostic criteria can differ between regions; for example, what might be diagnosed as GD in the US might not meet the criteria in the UK, highlighting the varying approaches to identifying the condition.

## What it tends to feel like

Often, gestational diabetes doesn't have obvious symptoms, which is why screening is so important. Many people feel no different at all, making the diagnosis feel unexpected. However, for some, there might be subtle signs like increased thirst, more frequent urination, or fatigue. Receiving a GD diagnosis can bring a wave of emotions, from surprise to concern, and it's common to experience [Pregnancy Anxiety](/conditions/pregnancy-anxiety) as you navigate new information and adjustments. As a doula, I often see how this initial overwhelm can be eased by clear, evidence-based conversations about what the diagnosis means for *you*.

## What the evidence says helps

The good news is that for many, gestational diabetes can be effectively managed. Research indicates that a significant percentage of GD cases are managed through lifestyle adjustments alone, focusing on diet and exercise. This might involve working with a dietitian to understand how different foods impact your blood sugar and incorporating gentle, regular movement into your day. For others, medication like insulin or metformin may be recommended by your care provider to help keep blood sugar levels within target ranges. These targets, such as fasting blood glucose below 95 mg/dL and 1-hour post-meal below 140 mg/dL, are set to promote optimal health for both you and your baby. Emerging evidence also suggests that continuous glucose monitors (CGMs) are being adopted, offering promising results for more precise blood sugar management.

## Working with your care team

Navigating a GD diagnosis is a collaborative effort with your healthcare team. Your provider is your best resource for your specific situation, helping you understand your individual targets and treatment plan. Regular monitoring of your blood sugar levels will likely be a part of your routine. It's an opportunity to learn more about your body and how it responds to different foods and activities. If the demands of managing GD begin to feel overwhelming, it's important to share those feelings with your provider, as ongoing stress can sometimes contribute to conditions like [Perinatal Depression](/conditions/perinatal-depression). Remember, you get to decide what feels right for you, and your care team is there to offer options and support. Just as with understanding any unexpected health development in pregnancy, from managing [Pregnancy Anxiety](/conditions/pregnancy-anxiety) to understanding conditions like [Subchorionic Hemorrhage](/conditions/subchorionic-hemorrhage), clear information empowers you to make informed decisions and feel more confident.
