Diabetes: Complete Guide to Understanding the Disease
Diabetes is a common chronic condition that affects how the body uses glucose (blood sugar). When diabetes is not properly controlled, high blood sugar can gradually affect important organs such as the heart, kidneys, eyes, nerves, and feet.
What Is Diabetes?
Insulin is a hormone that helps glucose move from the blood into the body’s cells to be used for energy. Diabetes develops when the body does not produce enough insulin, does not use insulin effectively, or both.
Main Types of Diabetes
Type 1 Diabetes: The body produces little or no insulin. It usually requires lifelong insulin treatment.
Type 2 Diabetes: The body becomes resistant to insulin and may eventually produce less insulin. It is the most common type of diabetes and can often be managed with lifestyle changes, medicines, and sometimes insulin.
Gestational Diabetes: Diabetes that develops during pregnancy. It usually requires careful monitoring because it can affect both mother and baby.
Common Symptoms
Some people may have no symptoms, especially in the early stages. Possible symptoms include:
Increased thirst and frequent urination
Increased hunger
Unusual tiredness
Unexplained weight loss
Blurred vision
Slow-healing wounds
Frequent infections
Tingling or numbness in the hands or feet
If you notice these symptoms, consult a healthcare professional and consider getting your blood sugar tested.
What Causes Diabetes?
Type 1 diabetes is related to an autoimmune process that damages insulin-producing cells. Type 2 diabetes is influenced by factors such as family history, excess body weight, physical inactivity, age, and other metabolic risk factors.
Gestational diabetes occurs because pregnancy-related hormonal changes can increase insulin resistance.
How Is Diabetes Diagnosed?
Diabetes can be diagnosed using blood glucose tests such as:
Fasting blood glucose
HbA1c
Oral glucose tolerance test
Random blood glucose in appropriate circumstances
Your doctor will decide which tests are appropriate based on your symptoms and health history.
How Can Diabetes Be Managed?
Good diabetes management usually involves a combination of:
Healthy eating: Choose balanced meals with vegetables, whole grains, appropriate portions of protein, and high-fibre foods. Limit sugary drinks and highly processed foods.
Regular physical activity: Staying physically active can improve insulin sensitivity and support healthy blood sugar levels.
Medication: Take diabetes medicines or insulin exactly as prescribed. Do not stop or change medication without medical advice.
Blood sugar monitoring: Regular monitoring can help you and your healthcare team understand how food, activity, illness, and medication affect your blood sugar.
Regular check-ups: Routine medical visits help identify complications early and allow treatment to be adjusted when needed.
Possible Complications
Long-term uncontrolled diabetes can increase the risk of:
Heart disease and stroke
Kidney disease
Eye complications
Nerve damage
Foot ulcers and infections
The good news is that good blood sugar control, blood pressure management, healthy lifestyle habits, and regular screening can help reduce the risk of complications.
