World Diabetes Day: Understanding Diabetes, Prevention and Management
Diabetes is one of the most common chronic health conditions affecting people across the world. It occurs when the body cannot produce enough insulin or cannot use insulin effectively, resulting in increased blood glucose levels. With changing lifestyles, unhealthy dietary habits, physical inactivity and increasing obesity, diabetes has become an important public health concern. World Diabetes Day is observed every year on 14 November to raise awareness about diabetes, encourage early diagnosis and promote better disease management. Understanding diabetes, Recognising its symptoms and adopting healthy lifestyle habits can help reduce complications and improve quality of life.
What Is Diabetes?
Diabetes mellitus is a chronic condition characterised by elevated blood glucose levels. Insulin, a hormone produced by the pancreas, helps glucose enter the body’s cells, where it is used for energy.
When insulin production is insufficient or the body cannot use insulin effectively, glucose accumulates in the bloodstream.
If left uncontrolled, diabetes can affect several organs, including the heart, kidneys, eyes, nerves and blood vessels.
What Are the Different Types of Diabetes?
1. Type 1 Diabetes
Type 1 diabetes is an autoimmune condition in which the body’s immune system attacks the insulin-producing cells of the pancreas.
As a result, the body produces little or no insulin. People with Type 1 diabetes require insulin treatment to manage their blood glucose levels.
It can develop during childhood, adolescence or adulthood.
2. Type 2 Diabetes
Type 2 diabetes is the most common form of diabetes. It develops when the body becomes resistant to insulin or does not produce enough insulin to maintain normal blood glucose levels.
Risk factors include:
- Overweight and obesity.
- Physical inactivity.
- Unhealthy dietary habits.
- Family history of diabetes.
- Increasing age.
- History of gestational diabetes.
Type 2 diabetes can often be managed through lifestyle changes, medication and regular medical monitoring.
3. Gestational Diabetes
Gestational diabetes develops during pregnancy when blood glucose levels become higher than normal.
It requires appropriate monitoring and management to protect both the mother and baby. Women who develop gestational diabetes may also have an increased risk of developing Type 2 diabetes later in life.
What Are the Common Symptoms of Diabetes?
Diabetes may develop gradually, and some people may not experience noticeable symptoms during the early stages.
Common warning signs include:
- Increased thirst.
- Frequent urination.
- Increased hunger.
- Unexplained weight loss.
- Persistent tiredness.
- Blurred vision.
- Slow-healing wounds.
- Frequent infections.
- Tingling or numbness in the hands and feet.
If you experience these symptoms, consult a healthcare professional and consider appropriate blood glucose testing.
Who Is at Risk of Developing Diabetes?
Several factors can increase the risk of developing diabetes, particularly Type 2 diabetes.
These include:
- Family history of diabetes.
- Excess body weight, particularly abdominal obesity.
- Sedentary lifestyle.
- Unhealthy eating patterns.
- High blood pressure.
- Abnormal cholesterol levels.
- Previous gestational diabetes.
- Polycystic ovary syndrome (PCOS).
People with these risk factors should discuss appropriate screening and preventive measures with their doctor.
How Is Diabetes Diagnosed?
Diabetes can be diagnosed through laboratory blood tests.
Common investigations include:
- Fasting Blood Glucose: Measures blood glucose after fasting for at least eight hours.
- Postprandial Blood Glucose: Measures blood glucose after a meal, commonly two hours after eating, depending on the test ordered.
- HbA1c Test: Measures average blood glucose levels over approximately the previous two to three months.
- Oral Glucose Tolerance Test (OGTT): Measures how the body responds to a glucose drink and is commonly used in the assessment of gestational diabetes and selected other situations.
For non-pregnant adults, commonly used diagnostic thresholds include:
- Fasting plasma glucose: 126 mg/dL or higher.
- HbA1c: 6.5% or higher.
- Two-hour plasma glucose during a 75 g OGTT: 200 mg/dL or higher.
- Random plasma glucose: 200 mg/dL or higher in a person with classic symptoms of hyperglycaemia or a hyperglycaemic crisis.
In the absence of unequivocal hyperglycaemia, confirmatory testing is generally required. Your doctor will interpret results based on your clinical condition.
How Can Diabetes Be Managed?
Diabetes management involves maintaining blood glucose levels within an appropriate target range and preventing long-term complications.
1. Follow a Balanced Diet
A healthy diet is an important part of diabetes management.
- Include vegetables, whole grains and fibre-rich foods.
- Choose appropriate portions of rice, cereals and other carbohydrates.
- Include healthy protein sources such as pulses, beans, eggs and fish.
- Limit sugary drinks, sweets and highly processed foods.
- Follow a consistent meal routine based on medical advice.
2. Stay Physically Active
Regular physical activity can improve insulin sensitivity and help manage blood glucose levels.
Activities may include:
- Walking
- Cyclying
- Swimming
- Yoga
- Strength-training exercises.
Aim for around 150 minutes of moderate-intensity physical activity per week, if medically suitable. People with existing complications should seek medical advice before starting an exercise programme.
3. Monitor Blood Glucose Regularly
Regular monitoring helps patients and doctors understand how diet, physical activity and medication affect blood glucose levels.
The frequency of testing depends on the type of diabetes, treatment plan and individual health requirements.
4. Take Prescribed Medication
Some patients require oral medicines, injectable medicines or insulin to control blood glucose levels.
Take medication as prescribed and do not stop or change doses without consulting your doctor.
5. Maintain a Healthy Weight
Maintaining a healthy body weight can improve blood glucose control and reduce the risk of complications, particularly in people with Type 2 diabetes.
What Are the Complications of Uncontrolled Diabetes?
Long-term uncontrolled diabetes can damage blood vessels and nerves, increasing the risk of several complications.
Heart and Blood Vessel Problems: Diabetes increases the risk of heart disease, heart attack and stroke.
Kidney Disease: Damage to the small blood vessels in the kidneys can lead to diabetic kidney disease.
Eye Problems: Diabetic retinopathy can damage the blood vessels of the retina and may lead to vision loss if not detected and treated appropriately.
Nerve Damage: Diabetic neuropathy may cause numbness, tingling, burning sensations or pain, particularly in the feet.
Diabetic Foot Problems: Reduced sensation and poor circulation can increase the risk of foot ulcers, infections and delayed wound healing.
Regular health check-ups and appropriate screening can help identify complications early.
How Can You Prevent Type 2 Diabetes?
Although some risk factors cannot be changed, adopting healthier habits can significantly reduce the risk of Type 2 diabetes, particularly among people at increased risk.
- Maintain a healthy body weight.
- Eat a balanced and nutritious diet.
- Exercise regularly.
- Avoid tobacco use.
- Limit sugary beverages.
- Get adequate sleep.
- Attend regular health check-ups.
- Follow medical advice if diagnosed with prediabetes.
Small, consistent lifestyle changes can make a meaningful difference to long-term health.
Why Are Regular Diabetes Check-Ups Important?
Diabetes management involves more than checking blood glucose levels. Regular assessments help monitor overall health and identify complications.
Depending on individual needs, doctors may recommend:
- HbA1c testing.
- Blood pressure monitoring.
- Cholesterol testing.
- Kidney function tests.
- Urine albumin testing.
- Regular eye examinations.
- Foot examinations.
- Weight and nutritional assessment.
Following a structured monitoring plan helps patients manage diabetes more effectively.
When Should You Consult a Doctor?
Consult a healthcare professional if you experience excessive thirst, frequent urination, unexplained weight loss, persistent fatigue or blurred vision.
People already diagnosed with diabetes should attend regular follow-up consultations and report any new symptoms.
Seek emergency medical attention if you experience severe confusion, unconsciousness, seizures, difficulty breathing or other signs of a serious blood glucose emergency.
