Diabetes is one of the fastest-growing health conditions worldwide and has become a major public health concern in Nigeria. Millions of people are living with diabetes, while many others remain undiagnosed until serious complications develop.
The good news is that diabetes can be prevented in many cases and effectively managed when diagnosed early. Understanding the warning signs, risk factors, and treatment options can help individuals live long, healthy, and productive lives.
At Lily Hospitals, we are committed to helping patients prevent, detect, and manage diabetes through comprehensive screening, expert medical care, lifestyle counselling, and ongoing support.
What is Diabetes?
Diabetes mellitus is a chronic medical condition that occurs when the body cannot properly regulate blood sugar (glucose). Glucose is the body’s primary source of energy and comes from the food we eat.
The hormone insulin, produced by the pancreas, helps move glucose from the bloodstream into the body’s cells, where it is used for energy. When the body does not produce enough insulin or cannot effectively use the insulin it produces, glucose builds up in the bloodstream, resulting in high blood sugar levels.
If left untreated, persistently high blood sugar can damage vital organs, including the heart, kidneys, eyes, nerves, and blood vessels.
Types of Diabetes
1. Type 1 Diabetes
Type 1 diabetes is an autoimmune disease in which the body’s immune system mistakenly attacks the insulin-producing cells in the pancreas.
People with Type 1 diabetes produce little or no insulin and require lifelong insulin therapy.
It commonly develops during childhood or adolescence but can occur at any age.
Common Features
- Sudden onset
- Rapid weight loss
- Increased thirst
- Frequent urination
- Requires daily insulin injections
2. Type 2 Diabetes
Type 2 diabetes is the most common form, accounting for over 90% of diabetes cases worldwide.
In Type 2 diabetes, the body becomes resistant to insulin or does not produce enough insulin to maintain normal blood sugar levels.
It usually develops gradually and is strongly linked to lifestyle factors.
Risk Factors Include:
- Being overweight or obese
- Physical inactivity
- Family history of diabetes
- High blood pressure
- High cholesterol
- Age above 45 years
- Previous gestational diabetes
3. Gestational Diabetes
Gestational diabetes develops during pregnancy.
Although it often disappears after childbirth, women who have had gestational diabetes are at increased risk of developing Type 2 diabetes later in life.
Proper monitoring during pregnancy is essential to protect both mother and baby.
Symptoms of Diabetes
Diabetes symptoms may develop gradually, especially in Type 2 diabetes.
Common symptoms include:
- Frequent urination
- Excessive thirst
- Increased hunger
- Unexplained weight loss
- Fatigue
- Blurred vision
- Slow-healing wounds
- Frequent infections
- Numbness or tingling in the hands and feet
- Dry mouth
- Itchy skin
Some individuals experience no symptoms at all and only discover they have diabetes during routine health screening.
Causes of Diabetes
The exact causes vary depending on the type.
Type 1 Diabetes
The exact cause remains unknown but is believed to involve:
- Autoimmune reactions
- Genetic predisposition
- Environmental triggers
Type 2 Diabetes
Usually develops due to a combination of:
- Excess body weight
- Poor diet
- Physical inactivity
- Family history
- Aging
- Hormonal disorders
Who is at Risk?
You are at increased risk if you:
- Have a parent or sibling with diabetes
- Are overweight
- Exercise less than three times weekly
- Have high blood pressure
- Have abnormal cholesterol levels
- Have polycystic ovary syndrome (PCOS)
- Had gestational diabetes
- Delivered a baby weighing over 4 kg
- Are above 45 years old
Complications of Diabetes
Without proper treatment, diabetes can affect nearly every organ in the body.
Heart Disease
People with diabetes are significantly more likely to develop:
- Heart attacks
- Stroke
- Hypertension
- Peripheral artery disease
Kidney Disease
Diabetes is one of the leading causes of chronic kidney disease and kidney failure.
Routine kidney function tests help detect problems early.
Eye Problems
High blood sugar damages the tiny blood vessels in the eyes.
This may lead to:
- Diabetic retinopathy
- Cataracts
- Glaucoma
- Vision loss
Annual eye examinations are strongly recommended.
Nerve Damage
Persistently elevated blood sugar can damage nerves, leading to:
- Tingling
- Burning sensations
- Numbness
- Loss of sensation
This increases the risk of unnoticed injuries.
Diabetic Foot
Poor circulation and nerve damage can cause:
- Foot ulcers
- Infections
- Gangrene
Regular foot care can prevent serious complications.
Sexual Dysfunction
Diabetes may contribute to erectile dysfunction in men and reduced sexual function in women due to nerve and blood vessel damage.
How is Diabetes Diagnosed?
Doctors diagnose diabetes using blood tests.
Common tests include:
Fasting Blood Sugar (FBS)
Measures blood sugar after fasting for at least eight hours.
Random Blood Sugar
Measures blood sugar regardless of when you last ate.
HbA1c Test
Measures average blood sugar over the previous two to three months.
It is one of the most reliable tests for diagnosis and long-term monitoring.
Oral Glucose Tolerance Test (OGTT)
Frequently used during pregnancy to diagnose gestational diabetes.
Treatment of Diabetes
Although diabetes has no permanent cure, it can be effectively controlled.
Treatment usually combines medication with healthy lifestyle choices.
Healthy Eating
A balanced diet is essential.
Choose:
- Vegetables
- Fruits
- Whole grains
- Beans
- Lean proteins
- Healthy fats
Limit:
- Sugary drinks
- Processed foods
- Excess carbohydrates
- Fried foods
Regular Exercise
Physical activity helps the body use insulin more effectively.
Adults should aim for at least 150 minutes of moderate exercise weekly, including activities such as brisk walking, cycling, swimming, or dancing.
Weight Management
Losing even 5–10% of body weight can significantly improve blood sugar control in people with Type 2 diabetes.
Medications
Depending on the type and severity of diabetes, treatment may include:
- Oral diabetes medications
- Injectable medications
- Insulin therapy
Always take medications exactly as prescribed by your healthcare provider.
Blood Sugar Monitoring
Regular blood sugar monitoring helps determine whether treatment is working.
Some patients may need daily monitoring, while others require periodic laboratory testing.
Can Diabetes Be Prevented?
Although Type 1 diabetes cannot currently be prevented, many cases of Type 2 diabetes can.
Prevention strategies include:
- Maintaining a healthy weight
- Exercising regularly
- Eating balanced meals
- Avoiding smoking
- Limiting alcohol intake
- Sleeping adequately
- Managing stress
- Attending routine medical check-ups
