“I’m young, I feel fine.” That single thought is how high blood pressure and diabetes catch so many Nigerians in their 20s and 30s — quietly, with no warning, until the damage is already done. These conditions are no longer “an old person’s problem.” This guide covers the numbers that matter and the simple steps that lower your risk.
Watch: the 60-second version — then read on for the full guide.
They’re common — and they’re getting younger
Roughly one in three Nigerian adults now lives with high blood pressure, and more than 11 million live with diabetes. In 2024 alone, diabetes was linked to over 55,000 deaths in Nigeria. These are not rare, far-away statistics — they are family, colleagues, and increasingly, young adults.
Why they’re called “silent” killers
The danger isn’t just how common they are — it’s how quietly they work. Fewer than 3 in 10 people with hypertension are even aware they have it. For diabetes it’s worse: across the IDF Africa Region, 54% of people living with diabetes are undiagnosed — the highest of any region in the world.
You can feel completely well while your blood pressure or blood sugar is doing damage in the background. “Feeling fine” is not the same as being healthy.
Know your numbers
The only way to catch a silent killer is to measure it.
- Blood pressure is generally considered high at 140/90 or above. A check takes two minutes at any pharmacy or clinic.
- Blood sugar has its own cut-offs — but those are for your clinician to read and explain, not to self-judge from a single reading.
If you don’t know your numbers, that’s the first thing to fix. Nigeria’s “Know Your Numbers” screening drive (part of the national Project 10 Million) exists precisely so people can check for free at hundreds of sites.
What untreated damage looks like
Left unmanaged, high blood pressure and diabetes are leading causes of stroke, heart attack, kidney failure, vision loss, and amputation. The point of catching them early isn’t fear — it’s that early, they’re very manageable; late, they take your health, your savings, or both.
The money reason to catch it early
Managing these conditions in Nigeria has become brutally expensive. Reporting in 2026 puts the rise in insulin prices at more than 200% since 2023 — a vial that cost about ₦3,500 now runs ₦18,000–₦21,000, and a pack of five long-acting pens went from around ₦22,000 to ₦58,000. Some patients now spend over ₦100,000 a month on diabetes care.
With most health costs paid out of pocket, that price tag pushes people into rationing or stopping treatment — which is exactly how complications begin. Catching trouble early, while lifestyle still does much of the work, is the cheapest medicine there is.
How to lower your risk
None of this guarantees anything — but each step meaningfully lowers your risk:
- Know your numbers. Get your blood pressure and blood sugar checked, even if you feel fine — especially if hypertension or diabetes runs in your family.
- Ease off the salt. The WHO recommends adults keep salt under 5 g a day — roughly one level teaspoon, counting what’s already in seasoning cubes, processed food, and the pot.
- Move most days. Aim for the WHO’s 150 minutes of moderate activity a week — brisk walking counts.
- Lean into whole foods, ease off sugary drinks and heavily processed food.
- Family history matters. If a close relative has hypertension or diabetes, your risk is higher — so check earlier and more often.
Get checked
You don’t need to feel sick to be at risk. Book a blood-pressure and blood-sugar check this month — at your pharmacy, clinic, or a free screening site. Knowing your numbers is the single most powerful thing you can do in your 20s and 30s.
