Type 2 Diabetes: Treatment in Nigeria
Updated July 2026 · Educational information — not a substitute for a doctor or pharmacist
Type 2 diabetes — persistently high blood sugar because the body stops responding properly to insulin — affects millions of Nigerian adults, and cases are rising with urban diets and less active lifestyles. Uncontrolled, it quietly damages eyes, kidneys, nerves, and blood vessels; controlled, people live full normal lives.
Treatment in Nigeria follows the same logic as everywhere: start with metformin plus diet and activity changes, add a second tablet (commonly the sulfonylurea glibenclamide) if sugar stays high, and move to insulin when tablets are no longer enough or in special situations. Regular monitoring — not guesswork — is what keeps treatment on track.
Two practical Nigerian realities matter: insulin must be kept cool (a challenge with unreliable power — a clay pot or cool box works when there's no fridge), and 'herbal cures' marketed for diabetes have repeatedly been found adulterated or useless. There is no cure; there is good control.
Signs & symptoms
- Urinating often, especially at night
- Unusual thirst and dry mouth
- Tiredness; blurred vision
- Wounds that heal slowly; repeated skin or urinary infections
- Numbness or burning in the feet
- Often no symptoms at all — screening is how most cases should be found
Medicines used for type 2 diabetes in Nigeria
Each medicine links to its full guide — uses, dosage forms, current naira prices, and NAFDAC-registered brands. Diagnosis and dosing belong with a clinician or pharmacist.
First-line tablet for type 2 diabetes — the foundation of nearly every regimen
Prescription required
Sulfonylurea add-on when metformin alone isn't enough; can cause low blood sugar, especially in older adults
Prescription required
Injected when tablets no longer control sugar, and in pregnancy, surgery, or very high readings; needs cool storage
Prescription required
How it's treated
Metformin is the foundation: it's effective, doesn't cause low sugar on its own, and protects the heart. Stomach upset early on usually settles if it's taken with food and the dose is increased gradually.
Know hypoglycaemia. Glibenclamide and insulin can push sugar too low — shakiness, sweating, palpitations, confusion. Every user (and their family) should know the response: take glucose, sweets, or a sugary drink immediately, then eat. Recurrent 'hypos' mean the regimen needs adjusting, not enduring.
See a doctor if…
- Fasting blood sugar repeatedly above 7.0 mmol/L (126 mg/dL) — to confirm diagnosis and start treatment
- Symptoms of very high sugar: extreme thirst, rapid breathing, drowsiness, fruity-smelling breath — emergency
- Repeated low-sugar episodes on treatment
- Any foot wound, ulcer, or numbness — diabetic feet deteriorate fast
- Pregnancy (existing diabetes or diabetes found in pregnancy) — needs specialist care, usually insulin
- Annual eye and kidney checks even when you feel well
Prevention
- Screen from age 35–40 (earlier with family history or overweight) — a simple fasting glucose test at any lab or pharmacy
- Cut sugary drinks; watch portion sizes of rice, garri, and other refined starches — swap toward beans, vegetables, whole grains
- Stay active and keep weight in a healthy range — modest weight loss measurably delays or prevents type 2 diabetes
- If told you're 'pre-diabetic', act then: that's the stage where the condition is most reversible
