Type 2 diabetes has become a growing health concern in Nigeria, with an estimated 7 out of every 100 Nigerians currently living with the condition. This rate nearly doubles the 2019 estimate by the International Diabetes Federation.
At the heart of type 2 diabetes is insulin resistance, where the body’s cells stop responding effectively to insulin — the hormone responsible for managing blood sugar. Left unmanaged, this can lead to persistently high blood sugar and serious long-term health complications.
Who’s at Risk?
Several factors increase the risk of developing type 2 diabetes:
1. Family history
2. Obesity, especially belly fat
3. Lack of exercise
4. Age
5. Certain ethnic backgrounds (including African descent)
6. Poor diets high in sugar and processed foods
7. Hormonal disorders (e.g. Cushing syndrome)
8. Low birth weight or being born preterm
9. Gestational diabetes in mothers
The Warning Signs
Early symptoms may be subtle but should not be ignored:
1. Frequent urination
2. Excessive thirst
3. Blurry vision
4. Fatigue
5. Numbness in hands or feet
6. Unexplained weight loss
7. Slow-healing wounds
Some individuals may not show any symptoms at all — making regular screening essential.
The Danger of Prediabetes
An estimated 12.5 million Nigerian adults are living with prediabetes — higher than normal blood sugar, but not yet diabetes. Without lifestyle changes, many of these individuals are at risk of developing full-blown type 2 diabetes.
Why It Matters
If untreated, type 2 diabetes can lead to:
1. Kidney disease
2. Heart attack or stroke
3. Nerve damage
4. Vision loss or blindness
5. Foot complications, including amputations
6. Mental health issues
6. Poor sleep and hearing problems
Prevention & Management
The good news? Type 2 diabetes is largely preventable — and even manageable if caught early. Here’s how:
1. Lose excess weight
2. Exercise regularly (at least 150 minutes/week)
3. Eat a balanced diet: Focus on whole grains, lean protein, fruits, and vegetables
4. Avoid sugary drinks and processed foods
5. Quit smoking
6. Sleep well (7–8 hours per night)
7. Monitor your blood sugar regularly if you’re at risk
Final Word
Diabetes is not a death sentence. With early detection, smart lifestyle choices, and medical guidance, individuals can live full, healthy lives. As Ojenagbon, a health communication expert, reminds us — prevention is possible, and control is within reach.
