Gestational diabetes guide
Introduction
Gestational diabetes guide aims to help Canadians understand this common condition during pregnancy. It occurs when blood sugar levels rise too high, affecting both mother and baby. Knowing the basics can improve health outcomes and reduce risks associated with this condition.
Medically reviewed by SASI Medical Review Board.
This guide covers key points about gestational diabetes, including:
- What causes it
- How it is diagnosed
- Possible symptoms
- Management and treatment options
- Ways to prevent complications
Gestational diabetes usually develops in the second or third trimester of pregnancy. It happens because the body cannot produce enough insulin to meet the increased needs during pregnancy. Insulin is a hormone that helps regulate blood sugar levels. Without proper control, gestational diabetes may lead to problems such as high birth weight, preterm delivery, or complications during labour.
Early detection and care are essential for reducing risks. Regular prenatal visits help monitor blood sugar levels and overall health. Lifestyle changes, like a balanced diet and physical activity, often play a major role in managing the condition effectively. In some cases, medication may be necessary to maintain healthy blood sugar levels.
Understanding gestational diabetes empowers expectant mothers to take charge of their health. This guide provides clear, practical information to support a healthy pregnancy journey in Canada, helping you make informed decisions and work closely with your healthcare team.
Key facts about gestational diabetes
This gestational diabetes guide highlights important information for expectant mothers. Understanding these key facts can help manage health during pregnancy effectively and reduce potential complications.
- Gestational diabetes occurs when blood sugar levels rise during pregnancy due to insufficient insulin production.
- It affects about 2 to 10 percent of pregnancies in Canada, with variations depending on risk factors.
- Risk factors include obesity, family history of diabetes, previous gestational diabetes, advanced maternal age, and certain ethnic backgrounds.
- Screening usually happens between 24 and 28 weeks of pregnancy, but earlier testing may be recommended for high-risk individuals.
- Managing diet and physical activity can help control blood sugar levels and improve pregnancy outcomes.
- Untreated gestational diabetes may increase risks for both mother and baby, including preeclampsia, cesarean delivery, and neonatal hypoglycaemia.
- Most women return to normal blood sugar levels after delivery, but follow-up is important to monitor for type 2 diabetes later in life.
Symptoms of gestational diabetes
Gestational diabetes often develops without clear symptoms. Many pregnant individuals may not notice any signs, which is why regular screening is important. When symptoms do appear, they can vary in severity and may resemble those of other conditions.
Common Symptoms
- Increased thirst and frequent urination
- Fatigue or feeling unusually tired
- Blurred vision
- Increased hunger
These symptoms result from elevated blood sugar levels affecting the body’s normal functions. They may develop gradually and can be mild, making them easy to overlook. It is important to report any such symptoms to your healthcare provider during prenatal visits.
Less Common Symptoms
- Recurrent infections, such as urinary tract infections
- Slow-healing sores or cuts
- Nausea or vomiting
While less frequent, these signs can indicate more significant blood sugar imbalances and should prompt medical evaluation. Persistent infections or delayed wound healing may signal the need for closer monitoring and treatment adjustments.
Red Flags
Immediate medical attention is necessary if any of the following occur:
- Severe abdominal pain
- Sudden swelling in hands or face
- Persistent vomiting
- Signs of labour before 37 weeks
Recognizing these red flags helps prevent complications for both mother and baby. This gestational diabetes guide emphasises the importance of monitoring symptoms closely throughout pregnancy and seeking prompt care when needed.
Causes and risk factors of gestational diabetes
Gestational diabetes occurs when the body cannot produce enough insulin during pregnancy. This leads to high blood sugar levels that affect both mother and baby. Understanding the causes and risk factors helps manage and prevent complications effectively.
Biological factors
Age plays a significant role. Women over 35 have a higher chance of developing gestational diabetes. Sex is not a factor since only pregnant individuals can develop this condition. Certain health conditions also increase risk:
- Obesity or overweight before pregnancy
- Polycystic ovary syndrome (PCOS)
- Previous gestational diabetes in earlier pregnancies
- Family history of type 2 diabetes
- High blood pressure or heart disease
Lifestyle factors
Diet and physical activity strongly influence risk. A diet high in processed foods, refined carbohydrates, and sugars can increase blood sugar levels. Lack of regular exercise reduces insulin sensitivity, making it harder for the body to regulate glucose. Smoking and excessive stress may also contribute to the development of gestational diabetes.
This gestational diabetes guide highlights that early screening and healthy lifestyle choices can reduce risks. Maintaining a balanced diet rich in whole foods and staying physically active during pregnancy support better outcomes for both mother and child. Additionally, managing stress and avoiding tobacco use are important preventive measures.
Diagnosis of gestational diabetes
Understanding the diagnosis process is key in managing gestational diabetes. This gestational diabetes guide explains what to expect during clinical evaluation, including history taking, physical examination, and common tests.
Clinical Evaluation and History
Your healthcare provider will review your medical history and assess risk factors such as age, weight, and family history of diabetes. They will also discuss any symptoms you may have noticed and evaluate your overall health status.
Physical Examination
A physical exam helps identify signs that may suggest gestational diabetes or related complications. This may include checking blood pressure, weight gain during pregnancy, and signs of other health issues that could affect pregnancy.
Common Tests
Screening tests are usually performed between 24 and 28 weeks of pregnancy. These include:
- Glucose challenge test (GCT): A preliminary screening where you drink a sugary solution, followed by a blood test to measure blood sugar levels after one hour.
- Oral glucose tolerance test (OGTT): If the GCT results are high, this more detailed test measures blood sugar levels over several hours after consuming a glucose-rich drink.
These tests help confirm whether gestational diabetes is present. Early diagnosis allows for timely management to protect both mother and baby from potential complications.
Treatment and management of gestational diabetes
Managing gestational diabetes requires a balanced approach that combines medical care with lifestyle changes. Early treatment helps protect both mother and baby from complications and supports a healthy pregnancy.
Conservative and medical treatments
Most women start with diet and exercise to control blood sugar levels. If these measures are not enough, healthcare providers may recommend medication such as insulin injections or oral agents that help regulate glucose. Regular monitoring of blood glucose is essential to adjust treatment as needed and ensure optimal control.
Lifestyle measures
Simple lifestyle changes can make a big difference. These include:
- Eating balanced meals with controlled carbohydrate intake, focusing on complex carbohydrates and fibre
- Engaging in moderate physical activity, like walking, swimming, or prenatal yoga, daily
- Maintaining a healthy weight gain during pregnancy as advised by your healthcare provider
- Monitoring blood sugar levels regularly at home using a glucometer
Follow-up
After delivery, blood sugar levels usually return to normal. However, follow-up testing is important to check for type 2 diabetes later in life. Healthcare providers will schedule postpartum glucose screening, typically six to twelve weeks after birth, and offer advice on long-term health maintenance. Continued healthy lifestyle habits are encouraged to reduce future diabetes risk.
This gestational diabetes guide emphasises the importance of teamwork between patients and healthcare professionals to ensure the best outcomes. Open communication and adherence to treatment plans are vital throughout pregnancy and beyond.
Prevention and self-care for gestational diabetes
Managing your health during pregnancy is key to reducing the risk of gestational diabetes. This gestational diabetes guide offers practical tips to help you stay healthy and support your baby’s development.
Healthy eating habits
Focus on balanced meals that include whole grains, lean proteins, and plenty of vegetables. Avoid sugary snacks and drinks, which can cause blood sugar spikes and contribute to excessive weight gain.
- Choose fibre-rich foods like oats, barley, legumes, and fresh fruits
- Eat small, frequent meals to maintain steady blood sugar levels throughout the day
- Limit processed foods, high-fat items, and foods high in added sugars
Physical activity
Regular exercise helps control blood sugar and improves overall well-being. Aim for at least 30 minutes of moderate activity most days, such as walking, swimming, or prenatal yoga. Always consult your healthcare provider before starting any new exercise routine during pregnancy to ensure it is safe for you and your baby.
Dos and don’ts
- Do monitor your blood sugar as advised by your healthcare provider
- Do stay hydrated and get enough rest to support your body’s needs
- Don’t skip meals or overeat, as both can cause blood sugar fluctuations
