Every year on November 14, World Diabetes Day brings people, families, healthcare professionals, and communities together to raise awareness of diabetes and the importance of access to appropriate care.
The theme for World Diabetes Day in 2026 and 2027 is Early Action on Diabetes. Led by the International Diabetes Federation (IDF), the campaign highlights two important priorities: identifying diabetes early and taking steps to reduce the risk of developing type 2 diabetes.
Early action can help people access the care, information, and support they need. It can also help reduce the risk of serious complications associated with diabetes.
In recognition of World Diabetes Day 2026, we're exploring what early action means, which symptoms to look out for, and how individuals, families, and communities can help raise awareness.
At Glucology, we believe that education comes first. This article provides general information about diabetes and early action. Whether you have recently been diagnosed, have been managing diabetes for many years, or simply want to learn more, we hope you find something useful here. You may already be familiar with the different types of diabetes, but there is always value in revisiting important information, discovering new resources, and staying informed about the latest guidance. Everyone's experience with diabetes is different, and learning something new can help you make informed decisions about your health and find the support you need.
Please remember that this article is for educational purposes only and does not replace personalized medical advice from your healthcare professional.
World Diabetes Day is a global awareness campaign observed every year on November 14. It was established in 1991 by the International Diabetes Federation and the World Health Organization to respond to growing concerns about diabetes worldwide.
The date marks the birthday of Sir Frederick Banting, who co-discovered insulin alongside Charles Best in 1921.
Each year, the campaign brings attention to different aspects of diabetes, including prevention, diagnosis, treatment, access to care, and the everyday experiences of people managing the condition.
This year, the theme, Early Action on Diabetes, focuses on the importance of recognizing diabetes sooner, reducing risk where possible, and making sure people can access the healthcare and support they need.
Diabetes affects how the body regulates glucose, commonly known as blood sugar. Glucose is an important source of energy, and insulin helps move glucose from the bloodstream into the body's cells.
When the body cannot produce enough insulin or use it effectively, glucose can build up in the bloodstream. Over time, persistently high blood glucose levels can damage blood vessels and nerves, affecting the heart, kidneys, eyes, and feet.
Early diagnosis allows people to begin appropriate treatment and receive advice on managing their condition. It also gives healthcare professionals an opportunity to monitor health, identify potential complications, and provide ongoing support.
However, diabetes can go undiagnosed for some time, particularly type 2 diabetes, which may develop gradually and cause few or no noticeable symptoms in its early stages.
Without a diagnosis, someone may not realize they need treatment or regular monitoring.
Early action helps address this gap by encouraging people to recognize possible warning signs, understand their risk, and speak with a healthcare professional when they have concerns.
Diabetes is not one single condition. The main types include type 1 diabetes, type 2 diabetes, and gestational diabetes.
Understanding the differences is important because the causes, risk factors, and approaches to care vary.
Type 1 diabetes is an autoimmune condition in which the immune system attacks the cells in the pancreas that produce insulin. As a result, the body produces little or no insulin.
It can develop at any age and is not caused by eating too much sugar or failing to follow a particular lifestyle.
Symptoms can develop quickly, sometimes over days or weeks. Early recognition and urgent medical assessment are important because untreated type 1 diabetes can lead to diabetic ketoacidosis (DKA), a potentially life-threatening emergency.
People with type 1 diabetes need insulin to survive and require ongoing support to manage their condition.
Type 2 diabetes occurs when the body does not respond to insulin effectively and, over time, may not produce enough insulin to maintain healthy blood glucose levels.
It is influenced by a combination of factors, including genetics, family history, age, and other health and environmental factors.
Type 2 diabetes can develop gradually, and some people may have no obvious symptoms for years.
Early identification is important because appropriate support and treatment can help manage blood glucose levels and reduce the risk of complications. For some people at increased risk, lifestyle changes and professional support may also help delay or prevent the onset of type 2 diabetes.
Type 2 diabetes is not simply the result of individual choices. People can develop the condition for many reasons, and everyone deserves respectful, nonjudgmental care.
Gestational diabetes develops during pregnancy when the body cannot produce enough insulin to meet its increased needs.
It often does not cause noticeable symptoms, which is why recommended pregnancy screening is important.
Gestational diabetes usually resolves after the baby is born, but it can increase the risk of developing type 2 diabetes later in life for the person who experienced it. Children born following a pregnancy affected by gestational diabetes may also have an increased risk of developing metabolic conditions.
Follow-up care after pregnancy and ongoing conversations with a healthcare professional can help people understand and manage their future risk.
Knowing the possible symptoms of diabetes is an important part of early action.
Common symptoms can include:
Feeling unusually thirsty.
Passing urine more frequently than usual.
Feeling tired or lacking energy.
Experiencing blurred vision.
Losing weight without trying.
Feeling hungrier than usual.
Cuts or wounds that heal slowly.
Experiencing recurrent infections.
Not everyone will experience these symptoms. Some people with type 2 diabetes may have no noticeable symptoms at all.
Symptoms can also have causes other than diabetes, so they should not be used to diagnose the condition yourself.
If you notice possible symptoms, arrange an appointment with your primary care doctor. A healthcare professional can assess your situation and determine whether blood tests or other investigations are appropriate.
Seek urgent medical attention if symptoms develop rapidly or are accompanied by vomiting, abdominal pain, deep or rapid breathing, unusual drowsiness, or confusion. These can be warning signs of a serious complication, including DKA. Call 000 in Australia if a medical emergency is suspected.
Recognizing symptoms early and seeking appropriate care can be particularly important for children and young people, in whom type 1 diabetes may develop quickly.
Anyone can develop type 2 diabetes, but certain factors can increase a person's risk.
These include:
Having a parent, sibling, or other close family member with type 2 diabetes.
Getting older.
Having previously experienced gestational diabetes.
Having high blood pressure or certain other metabolic risk factors.
Having a history of elevated blood glucose levels.
Having a level of physical activity, dietary pattern, or other health circumstances associated with increased risk.
Risk can also be influenced by social and environmental factors, including access to affordable nutritious food, safe places to exercise, and healthcare services.
Some groups, including Aboriginal and Torres Strait Islander peoples, have a higher risk of type 2 diabetes and may benefit from earlier or more frequent screening, based on their individual circumstances and clinical guidance.
Having one or more risk factors does not mean someone will definitely develop type 2 diabetes. Equally, people without obvious risk factors can still develop the condition.
Understanding your personal risk is a useful first step toward having an informed conversation with your healthcare professional.
Early action does not have to mean making several major changes at once. It can begin with a conversation, a health check, or learning more about your individual circumstances.
1. Talk to Your Primary Care Doctor About Your Risk
If you are concerned about diabetes or have risk factors for type 2 diabetes, speak with your primary care doctor about whether a risk assessment or blood glucose test is appropriate.
In Australia, the Australian Type 2 Diabetes Risk Assessment Tool (AUSDRISK) can help adults understand their risk. It is a risk assessment tool, not a diagnostic test.
Your doctor can explain the results and advise whether further testing or follow-up is needed.
Screening recommendations vary according to a person's age, medical history, and risk factors, so it is worth asking what is appropriate for you.
2. Build Sustainable Everyday Habits
For people at increased risk of type 2 diabetes, certain lifestyle changes may help reduce risk or delay the onset of the condition.
Depending on your circumstances, useful steps may include:
Eating a varied diet with vegetables, fruit, whole grains, legumes, and other nutritious foods.
Finding regular physical activities that suit your abilities, interests, and daily routine.
Getting enough sleep and seeking support for ongoing sleep difficulties.
Avoiding smoking and getting help to quit if needed.
Attending recommended health checks and following advice from your healthcare team.
There is no single routine that works for everyone. Changes should be realistic, accessible, and appropriate for your health needs.
These measures do not guarantee that type 2 diabetes will be prevented, and lifestyle changes cannot prevent type 1 diabetes. Anyone already diagnosed with diabetes should continue their prescribed treatment and speak with their healthcare team before making significant changes to their management plan.
3. Know Your Numbers
Blood glucose testing can help healthcare professionals identify diabetes and monitor how it is being managed.
Depending on the situation, testing may include fasting blood glucose or glycated hemoglobin (HbA1c), which provides information about average blood glucose levels over approximately two to three months.
Your doctor can explain which tests are suitable, what the results mean, and whether further testing is required.
For people already managing diabetes, regular monitoring may be part of their individual care plan. The right approach depends on the type of diabetes, treatment, and personal circumstances.
4. Attend Recommended Health Checks
Routine appointments can help identify concerns before they become more difficult to manage.
For people living with diabetes, regular reviews may include checking blood glucose management, blood pressure, cholesterol, kidney health, eye health, and foot health, depending on individual needs.
These appointments are also an opportunity to discuss treatment, daily challenges, and any questions that have come up since the previous visit.
If you are unsure which checks you need or how often you should have them, ask your healthcare professional to explain your care plan.
5. Seek Support When You Need It
Managing diabetes can involve many decisions, from understanding medication and monitoring blood glucose to planning meals, staying active, and dealing with the emotional demands of a long-term condition.
Support may come from a primary care doctor, endocrinologist, diabetes educator, registered dietitian, pharmacist, or other members of a person's healthcare team.
Family members, friends, and peer-support communities can also play a valuable role.
Asking questions and seeking help is a practical step toward making informed decisions. You do not have to work everything out on your own.
The message of World Diabetes Day is relevant to people who have not been diagnosed with diabetes, as well as those who are already managing the condition.
An early diagnosis is an important starting point, but ongoing care matters throughout a person's life.
Regular appointments, following an agreed treatment plan, and discussing changes in symptoms or health can help people and their healthcare teams identify concerns and adjust care when needed.
Practical support can make everyday management easier, too. Depending on a person's needs, this might include finding a suitable way to carry diabetes supplies, learning how to store medication correctly, or developing a routine for monitoring blood glucose.
Diabetes management is different for everyone. Products and tools can support daily routines, but they do not replace medical advice, prescribed treatment, or individual care plans.
The aim is to help people access reliable information and the support that suits their circumstances.
Diabetes awareness is a shared responsibility. Families, workplaces, schools, community organizations, and healthcare services can all help people access information and support.
Here are a few practical ways to get involved.
Small actions can help create an environment where people feel more comfortable asking questions and seeking support.
World Diabetes Day is an opportunity to pause, learn, and help others find reliable information.
This year's theme reminds us that earlier diagnosis, appropriate risk reduction, and access to ongoing care all matter. It also highlights the need to make screening and support available to people who might otherwise face barriers to healthcare.
You can take part by learning about the symptoms of diabetes, checking whether you are due for a health assessment, sharing trusted information, or starting a conversation with someone you care about.
If you are already managing diabetes, World Diabetes Day is also a chance to reflect on the support you have, ask questions about your care, and identify any practical help you may need.
At Glucology, we believe that educating people is an important first step toward better-informed decisions and stronger support for the diabetes community.
