Diabetes in Nigeria: Symptoms, Causes, Treatment & Prevention [2025 Guide]
Over 8 million Nigerians are living with diabetes right now — and at least half of them don't know it yet. If you've been feeling unusually thirsty, tired, or urinating more than normal, this guide is for you. A PCN-licensed Nigerian pharmacist explains everything you need to know.
🔬 Key Fact — Diabetes in Nigeria
1 in 14
Nigerian adults live with diabetes (Type 2)
That is approximately 8 million Nigerians — and the number is rising fast as urbanisation, sedentary lifestyles, and dietary changes accelerate. Most cases are diagnosed late or not at all.

Section 1 — What Is Diabetes?
What Is Diabetes? A Nigerian Pharmacist Explains Simply
Diabetes is a condition where your blood contains too much sugar (glucose) because your body either cannot produce enough insulin or cannot use it properly. Think of insulin as the key that unlocks your body's cells to let sugar in for energy — diabetes means that key is broken or missing.
When you eat foods like eba, rice, bread, or plantain, your body breaks them down into glucose, which enters your bloodstream. Normally, your pancreas — a gland behind your stomach — releases insulin to move that glucose from the blood into your cells, where it is used for energy. In diabetes, this process fails, and glucose builds up in your blood instead. Over time, high blood sugar damages blood vessels, nerves, kidneys, eyes, and the heart.[1]
The Three Main Types of Diabetes
Type 1
Autoimmune — Pancreas Produces No Insulin
The immune system attacks insulin-producing cells. Requires insulin injections for life. Less common in Nigeria — accounts for approximately 5–10% of diabetes cases. Often diagnosed in children and young adults.
WHO · IDF Diabetes Atlas 2024
Type 2
Insulin Resistance — Most Common in Nigeria
The body produces insulin but cells do not respond to it properly. Accounts for over 90% of diabetes in Nigeria. Strongly linked to lifestyle — diet, physical inactivity, obesity, and stress. Can often be managed with medication and lifestyle changes.
PMC · Cardiovascular Diabetology · 2024
GDM
Gestational — Occurs During Pregnancy
Develops during pregnancy and usually resolves after birth, but increases the risk of Type 2 diabetes later. Affects approximately 14% of pregnancies in Nigeria. Regular blood sugar monitoring during antenatal care is essential.
NDHS · FMOH Nigeria · 2023
💡 Key Takeaway
Type 2 diabetes is the most common form in Nigeria — and unlike Type 1, it is largely preventable and manageable. If you catch it early, you can significantly reduce your risk of serious complications through lifestyle changes and medication.
📊
Section 2 — Diabetes Statistics Nigeria 2025
How Many Nigerians Have Diabetes? The 2025 Statistics
Nigeria has a rapidly growing diabetes crisis that is not yet fully captured by official figures. The true burden is significantly higher than international estimates suggest — because most Nigerians with diabetes have never been diagnosed.
8.02M
Nigerians living with Type 2 diabetes
A 2024 meta-analysis of 60 Nigerian studies found that 7% of Nigerian adults — approximately 8.02 million people or 1 in 14 — live with Type 2 diabetes. This is nearly double the IDF's earlier estimate of 3.7%.[2]
PMC · Cardiovascular Diabetology · Dec 2024
50%+
Nigerian diabetics who are undiagnosed
More than half of Nigerians living with diabetes are undiagnosed, according to IDF Africa Region estimates. They have high blood sugar but don't know it — and are accumulating organ damage silently. This is the most dangerous aspect of Nigeria's diabetes crisis.[3]
IDF Diabetes Atlas · 2024
149%
Projected increase in sub-Saharan African diabetes cases by 2045
Diabetes cases in sub-Saharan Africa — including Nigeria — are projected to rise by 149% between 2019 and 2045, driven by urbanisation, dietary change, and population growth. Nigeria is at the centre of this epidemic.[4]
IDF · PMC · 2024
⚠️ The Silent Epidemic
In Nigeria, diabetes has gone from 2.2% prevalence in 1992 to 7% in 2024 — a more than threefold increase in one generation.
This explosive rise tracks directly with Nigeria's rapid urbanisation. As Nigerians moved from farming communities to cities like Lagos, Abuja, and Port Harcourt — where processed food is cheaper and physical activity is lower — the conditions for diabetes became ideal. White rice has replaced ofe akwu and traditional soups. Sugary drinks like Malta, Bigi Cola, and energy drinks replaced water and zobo. Motorcycle and car transport replaced walking. These are not moral failures — they are structural changes. But understanding them is the first step to reversing the trend.

💡 Key Takeaway
Nigeria's diabetes prevalence has more than tripled in 30 years and shows no sign of slowing. With over 8 million people affected and half undiagnosed, early testing is the single most important action any Nigerian adult can take — especially if you are over 35, overweight, or have a family history of diabetes.

Section 3 — Symptoms & Diagnosis
Early Warning Signs of Diabetes in Nigeria
Diabetes often develops silently — many Nigerians have had high blood sugar for years before their first symptom appears. However, these are the warning signs your body uses to tell you something is wrong. Do not ignore them.
The classic symptoms of diabetes are sometimes called the "4 Ts" — Thirsty (excessive thirst), Toilet (frequent urination), Tired (constant fatigue), and Thinner (unexplained weight loss). But in Nigeria, diabetes often presents differently from Western textbooks because of differences in body weight, diet, and the stage at which people seek care.[5]
🩺 Diabetes Symptom Checker
Tick the symptoms you are currently experiencing — your result updates instantly
✅ 0–2 symptoms: Low immediate concern. Monitor your health and consider a routine blood sugar test. A fasting blood glucose test at any MLSCN-accredited lab costs ₦500–₦1,500 in most Nigerian cities.
⚠️ 3–5 symptoms: Moderate concern. You should see a doctor or pharmacist within the next 48 hours. Request a fasting blood glucose (FBG) or HbA1c test. Do not delay.
🚨 6+ symptoms: High concern. Please seek medical attention today. These symptoms together suggest your blood sugar may be significantly elevated. Contact Enavec Pharmacy on WhatsApp for immediate pharmacist guidance: wa.me/2347068357391
⚠️ This tool is for awareness only — it is not a medical diagnosis. A blood test is the only way to confirm diabetes. Always consult a qualified healthcare professional.
How Diabetes Is Diagnosed in Nigeria
Diabetes is diagnosed with a blood test — not by symptoms alone. The three standard tests used in Nigerian hospitals and laboratories are:[6]
FBG
Fasting Blood Glucose
Fast for 8 hours (overnight), then test blood sugar. Normal: below 5.6 mmol/L. Prediabetes: 5.6–6.9 mmol/L. Diabetes: 7.0 mmol/L or above. Cost: ₦500–₦1,500 at most Nigerian labs. Available at MLSCN-accredited laboratories nationwide.
WHO Diagnostic Criteria · 2023
HbA1c
Glycated Haemoglobin (3-month average)
Shows your average blood sugar over the past 2–3 months. Normal: below 5.7%. Prediabetes: 5.7–6.4%. Diabetes: 6.5% or above. More expensive (₦3,000–₦8,000) but more informative — it cannot be faked with a single day of careful eating.
ADA Standards of Care · 2024
OGTT
Oral Glucose Tolerance Test
Drink a glucose solution, then test blood sugar at 2 hours. Diabetes confirmed if result is 11.1 mmol/L or above. Used especially in pregnancy (gestational diabetes screening). Available at most General Hospitals in Lagos, Abuja, Kano, Port Harcourt.
WHO · NDHS 2023
💡 Key Takeaway
If you are over 35, overweight, have a family history of diabetes, or experience 3 or more of the symptoms above — go for a fasting blood glucose test today. It costs as little as ₦500 and takes 20 minutes. Early diagnosis is the single most powerful tool you have against diabetes complications.
⚠️
Section 4 — Causes & Risk Factors
What Causes Diabetes? Risk Factors Every Nigerian Must Know
Type 2 diabetes does not happen overnight — it develops over years, driven by a combination of lifestyle, genetics, and environment. Understanding your personal risk factors is the first step to prevention.
Nigeria's rapid urban transition has created the perfect storm for diabetes. The shift from physically active rural livelihoods to sedentary city jobs, combined with cheap access to processed carbohydrates and sugary drinks, has fundamentally changed the metabolic environment for millions of Nigerians.[7]
🏙️
Urbanisation & Sedentary Lifestyle
Urban Nigerians are significantly more likely to develop Type 2 diabetes than rural Nigerians. Lagos, Abuja, and Port Harcourt show among the highest diabetes prevalence rates in the country. Sitting at a desk 8+ hours daily dramatically increases insulin resistance — your cells literally stop listening to insulin signals.
PMC · Cardiovascular Diabetology · 2024
🍚
High-GI Nigerian Diet
White rice, white bread, garri, and fufu are all high-glycaemic foods that spike blood sugar rapidly. The traditional Nigerian diet — rich in vegetables, whole grains, and unprocessed proteins — was actually protective. The problem is the shift to Westernised, processed versions of these foods in urban settings.
Lancet Nigeria NCD Report · 2022
👨👩👧
Family History & Genetics
If one parent has Type 2 diabetes, your lifetime risk doubles. If both parents have it, your risk increases by 4–6 times. This does not mean you will develop diabetes — but it means you must be more vigilant about diet, exercise, and regular blood sugar screening from your 30s onwards.
WHO · ADA Standards of Care · 2024
Additional major risk factors in the Nigerian context include: abdominal obesity (waist circumference above 94cm for men and 80cm for women increases risk substantially); hypertension (high blood pressure and diabetes frequently coexist — if you have one, screen for the other); previous gestational diabetes; excessive alcohol consumption (especially ogogoro, palm wine, and beer which are high in sugars and calories); and chronic stress which raises cortisol and blood sugar simultaneously.[8]
💡 Key Takeaway
Urban Nigerians who eat processed carbohydrates daily, exercise rarely, and have a family history of diabetes are in the highest risk group. If three or more of these risk factors apply to you, get tested now — regardless of whether you have symptoms.

Section 5 — Treatment
How Is Diabetes Treated in Nigeria? Your Complete Treatment Guide
Diabetes is not curable — but it is very manageable. With the right combination of medication, diet, and lifestyle, most Nigerians with Type 2 diabetes can live full, healthy lives. The key is starting treatment early and staying consistent.
Diagnosis Day
Blood Test Confirmed
FBG ≥7.0 or HbA1c ≥6.5%. Begin lifestyle modifications immediately. Doctor starts Metformin 500mg with meals if appropriate. Dietary counselling recommended.
Week 1–4
Lifestyle + Metformin
Reduce white rice, garri, sugary drinks. Start 30 min walking daily. Metformin dose may increase to 1000mg/day. Expect some GI side effects initially — these usually settle.
Month 3
First HbA1c Review
Target HbA1c <7% for most adults. If blood sugar remains high, doctor may add Glibenclamide or Glimepiride. Blood pressure and kidney function also reviewed.
Month 6
Monitor & Adjust
If lifestyle + 2 oral drugs fail to control blood sugar — or if complications develop — insulin therapy may be introduced. Refer to endocrinologist if available in your city.
Long Term
Maintenance & Prevention
6-monthly HbA1c, annual eye exam, annual kidney function test, foot examination. Target: HbA1c <7%, BP <130/80, no complications. Many Nigerians achieve this with Metformin alone + diet.
First-Line Diabetes Medications Available in Nigeria (NAFDAC-Registered)

💡 Key Takeaway
Metformin is the safest, most affordable, and most effective first-line drug for Type 2 diabetes in Nigeria — and it is available for as little as ₦200. If your doctor has prescribed it, take it consistently with your meals. Do not stop it because you feel better — feeling better means it is working, not that the diabetes has gone.
🚨
Section 6 — Complications
Diabetes Complications: What Happens When Blood Sugar Stays High
Uncontrolled diabetes is a slow emergency. High blood sugar silently damages blood vessels and nerves throughout the body, leading to complications that are largely preventable with early diagnosis and consistent treatment.
Most Vulnerable
Elderly · Obese · Uncontrolled HbA1c >9%
- Diabetic ketoacidosis (DKA)
- Hyperosmolar hyperglycaemic state
- Foot gangrene requiring amputation
- End-stage renal (kidney) failure
High Risk
Hypertensive · Long duration · Smoker
- Diabetic nephropathy (kidney disease)
- Retinopathy (blindness risk)
- Peripheral neuropathy (nerve damage)
- Heart attack or stroke
Moderate Risk
Newly diagnosed · HbA1c 7–8% · Overweight
- Recurrent infections (skin, UTI, thrush)
- Poor wound healing
- Diabetic foot ulcers
- Early retinopathy (detectable on exam)
Lower Risk
Newly diagnosed · HbA1c <7% · Active lifestyle
- Hypoglycaemia from medication
- Fatigue during blood sugar spikes
- Mild visual changes
- Dental gum disease
🦶 Nigeria-Specific Alert: The Diabetic Foot Crisis
Diabetes-related foot amputation is one of the most common surgical procedures in Nigerian teaching hospitals — almost entirely preventable.
A combination of factors makes diabetic foot disease particularly devastating in Nigeria: delayed diagnosis, poor glycaemic control, barefoot walking habits, traditional wound treatment with herbs, and limited access to podiatry services. If you have diabetes, never walk barefoot. Inspect your feet every day. Any wound, blister, or discolouration on the foot must be seen by a healthcare professional within 24 hours — not treated at home with hot water or traditional medicine. See your nearest hospital immediately.
FMOH Nigeria Clinical Guidelines · WHO Diabetic Foot Guidelines 2024💡 Key Takeaway
Every complication of diabetes is largely preventable with good blood sugar control. The target for most Nigerian adults with diabetes is an HbA1c below 7% — achievable with Metformin, lifestyle changes, and consistent follow-up care. Annual eye, kidney, and foot checks are not optional extras — they are what keep you out of the hospital.

Section 7 — Prevention & Lifestyle
How to Prevent Diabetes in Nigeria: Diet, Exercise & Lifestyle
Type 2 diabetes is largely preventable — and if you already have it, the same lifestyle changes that prevent it will help manage it. This section gives you practical, Nigeria-specific advice that works with your daily life.
Nigerian Foods That Raise Blood Sugar (High-GI — Limit These)
These foods cause rapid spikes in blood glucose. They are not banned — but portion control and frequency matter enormously for people at risk of or living with diabetes:[10]
⚠️ Limit Significantly
White rice (riz blanc) — very high GI, spikes blood sugar fast
Garri (eba) — high-GI cassava product; portions must be very small
Sugary drinks — Malta, Mirinda, Pepsi, Fanta, energy drinks
Agege bread & white bread — refined flour, high GI
Fried plantain (dodo) — ripe plantain is high in sugar; unripe is better
Zobo with sugar — without sugar, zobo is actually beneficial
Garri (eba) — high-GI cassava product; portions must be very small
Sugary drinks — Malta, Mirinda, Pepsi, Fanta, energy drinks
Agege bread & white bread — refined flour, high GI
Fried plantain (dodo) — ripe plantain is high in sugar; unripe is better
Zobo with sugar — without sugar, zobo is actually beneficial
⚡ Eat in Moderation
Yam (boiled) — moderate GI; portion-controlled yam is acceptable
Fufu (pounded yam) — high-carb but traditional; small portions with plenty of vegetable soup
Bananas (ripe) — medium GI; unripe banana is better for diabetics
Beans & black-eyed peas — actually low GI despite being carbs; excellent choice
Egusi soup — healthy on its own; the issue is what you eat it with
Fufu (pounded yam) — high-carb but traditional; small portions with plenty of vegetable soup
Bananas (ripe) — medium GI; unripe banana is better for diabetics
Beans & black-eyed peas — actually low GI despite being carbs; excellent choice
Egusi soup — healthy on its own; the issue is what you eat it with
✅ Eat Freely
Ugwu (fluted pumpkin) — high in fibre and nutrients; stabilises blood sugar
Bitter leaf (onugbu) — research shows blood sugar lowering properties
Okra — fibre-rich; slows glucose absorption significantly
Fish (tilapia, mackerel, catfish) — excellent lean protein
Eggs — very low GI; excellent Nigerian breakfast option
Unripe plantain — significantly lower GI than ripe; resistant starch

Eggs — very low GI; excellent Nigerian breakfast option
Unripe plantain — significantly lower GI than ripe; resistant starch
The 30-Minute Daily Rule
Physical activity is one of the most powerful tools for blood sugar control — and it is free. 30 minutes of moderate-intensity exercise every day reduces insulin resistance, lowers HbA1c by 0.5–1%, and reduces cardiovascular risk.[11] For Nigerians in Lagos or Abuja who say they have no time — walking briskly to your bus stop instead of taking a keke napep, using stairs instead of lifts, and parking further away all count. You do not need a gym membership. You need consistency.
💡 Key Takeaway
Switching from white rice to oats, brown rice, or unripe plantain; replacing sugary drinks with water and unsweetened zobo; walking 30 minutes daily; and losing just 5–10% of your body weight can reduce your risk of developing Type 2 diabetes by up to 58%. These are not small changes — they are life-changing ones.

Diabetes in Nigeria: State-by-State & Geographic Breakdown
Diabetes burden in Nigeria is not uniform — it varies dramatically by geography, income level, and urbanisation. Understanding where diabetes hits hardest helps target prevention resources where they are needed most.

Prevalence in 1992 (×3 rise)
FMOH · 1992Urban areas — particularly Lagos, Abuja, Kano, and Port Harcourt — show the highest diabetes prevalence in Nigeria due to sedentary occupations, high-carbohydrate fast food, stress, and limited physical activity. South West Nigeria (Lagos, Ogun, Oyo states) shows the highest diagnosis rates partly because of better healthcare access, not necessarily higher prevalence. Conversely, the North West and North East zones likely have higher true prevalence but lower diagnosis rates due to healthcare access gaps.
North West
Kano, Kaduna, Sokoto
High BurdenEstimated prevalence 8–10%. Urbanisation in Kano drives high rates. Very low diagnosis rates due to healthcare access gaps. High sugar intake from millet beer and sweetened teas.
Key states: Kano, Kaduna, KatsinaSouth West
Lagos, Ogun, Oyo
High BurdenHighest diagnosis rates in Nigeria. Lagos urban lifestyle — sedentary work, fast food, stress — drives prevalence. Better healthcare means more cases identified. Estimated 9–12% in metropolitan Lagos.
Key states: Lagos, Ogun, OyoSouth East
Anambra, Enugu, Imo
High BurdenHigh commercial activity and urbanisation. Dietary shift from traditional igbo foods (ofe onugbu, ugwu) to processed foods. Estimated prevalence 6–9%. Strong private healthcare sector means better diagnosis.
Key states: Anambra, Imo, EnuguSouth South
Rivers, Delta, Edo
Medium BurdenOil industry workers have high sedentary risk. Port Harcourt shows rising prevalence. Traditional foods (banga soup, edikaikong) are protective but being replaced by fast food in cities. Estimated 5–8%.
Key states: Rivers, Delta, Cross RiverNorth Central
FCT, Plateau, Kwara
Medium BurdenAbuja (FCT) shows high rates among civil servants and sedentary professionals. Plateau state benefits from cooler climate and more active traditional lifestyle. Estimated 4–7% overall.
Key states: FCT, Plateau, BenueNorth East
Borno, Adamawa, Gombe
Lower BurdenConflict in some areas has disrupted healthcare. Traditional rural lifestyle is somewhat protective. Estimated 3–5% but diagnosis rates are very low. Malnourishment complicates the clinical picture.
Key states: Borno, Yobe, Adamawa💡 Key Takeaway
If you live in Lagos, Kano, Abuja, or Port Harcourt, your diabetes risk is significantly elevated by your environment — not just your genetics. Urban Nigerian professionals in sedentary jobs who eat processed foods daily should prioritise annual blood sugar screening from age 30 onwards, not 45.

Section 10 — Myth vs Fact
Common Diabetes Myths in Nigeria — Debunked by a Pharmacist
Misinformation about diabetes is widespread in Nigerian communities, on social media, and even in some traditional healthcare settings. Here are the most dangerous myths — and the evidence-based facts that correct them.
❌ Myth
"If I feel fine, my diabetes must be under control — I don't need to take my medication."
✅ Fact
High blood sugar causes no pain. You can have an HbA1c of 11% and feel perfectly well while your kidneys and eyes are being silently damaged. Feeling fine is not evidence of good control — only your blood test tells the truth.
❌ Myth
"Bitter leaf, bitter kola, or herbal roots can cure diabetes permanently."
✅ Fact
Some Nigerian plants (bitter leaf, moringa, garlic) have modest blood sugar lowering effects supported by research — but none cure diabetes. Stopping prescribed Metformin to use herbs alone has led to DKA (diabetic coma) and death in Nigeria. Use herbs only as a complement, never as a replacement.[13]
❌ Myth
"Only fat people get diabetes. I am slim so I cannot have it."
✅ Fact
In Nigeria, a significant proportion of Type 2 diabetes cases occur in people with normal or below-normal BMI — a phenomenon called "lean diabetes" more common in African populations. Slim Nigerians can still develop diabetes, particularly if they have a family history or sedentary lifestyle.
❌ Myth
"Once I start insulin, I am in the final stage of diabetes and will die soon."
✅ Fact
Insulin is a life-saving medicine — not a death sentence. Starting insulin means your diabetes needs stronger management, which is a clinical decision, not a sign of failure or approaching death. Many Nigerians thrive on insulin for decades with excellent quality of life.

Section 11 — Frequently Asked Questions
Frequently Asked Questions About Diabetes in Nigeria
Quick Answer Excessive thirst, frequent urination (especially at night), unexplained fatigue, and blurred vision are the most common early signs. Other Nigerian-specific warning signs include: slow-healing wounds (especially on the feet), recurrent skin infections, unexplained weight loss, and dark patches of skin around the neck or armpits (called acanthosis nigricans). Many Nigerians have no symptoms at all in the early stages — which is why regular blood sugar testing from age 30 (or earlier with risk factors) is essential. Source: WHO Diabetes Diagnostic Criteria · ADA 2024.
Quick Answer Type 2 diabetes can go into remission with significant lifestyle changes, but it is not permanently cured. A 10% or greater reduction in body weight — achieved through diet and exercise — can put Type 2 diabetes into remission in some patients, meaning blood sugar returns to normal without medication. However, this is not permanent; diabetes typically returns if weight is regained or lifestyle reverts. Type 1 diabetes currently has no cure. The most realistic goal for most Nigerians with Type 2 diabetes is excellent control — not cure. Source: Lancet · DiRECT Trial 2023 · ADA 2024.
Quick Answer Metformin costs approximately ₦200–₦800 per pack at most Nigerian pharmacies, depending on brand and dosage. Generic Metformin (Emzor, May & Baker, Fidson brands) is significantly cheaper than branded Glucophage. A month's supply typically costs between ₦600 and ₦2,400 depending on your dose. Prices vary between Lagos, Abuja, Port Harcourt, and smaller cities. For current pricing at Enavec Pharmacy, contact us on WhatsApp: wa.me/2347068357391
Quick Answer Yes — but the quantity and preparation matter enormously. White rice is high glycaemic (GI ~70) and causes rapid blood sugar spikes. However, you can significantly reduce this impact by: (1) eating smaller portions — one cup cooked, not a full plate; (2) pairing rice with protein and vegetable soup (egusi, edikaikong, ofe onugbu) which slows absorption; (3) choosing parboiled or brown rice which has a lower GI; (4) cooling cooked rice before eating — cold rice forms resistant starch with a lower GI. Unripe plantain, oats, or brown rice are better alternatives for diabetics. Source: Glycaemic Index Foundation · NDHS Dietary Data 2023.
Quick Answer Type 1 is an autoimmune condition where the body destroys its own insulin-producing cells. Type 2 is a lifestyle-linked condition where the body stops responding to insulin properly. Type 1 requires insulin injections for life and cannot be prevented. Type 2 — which accounts for over 90% of diabetes in Nigeria — is largely preventable and manageable with lifestyle changes and oral medication. Type 1 is often diagnosed in childhood; Type 2 increasingly affects Nigerians from their 30s onwards. The treatment, monitoring, and lifestyle implications are completely different. Source: IDF Diabetes Atlas 2024 · WHO.
Quick Answer No — Berberine should never be used to replace prescribed Metformin without your doctor's approval. Clinical trials have shown Berberine can lower blood sugar with efficacy comparable to Metformin at 500mg three times daily. However, it is a supplement, not a NAFDAC-registered drug for diabetes treatment. Used alongside Metformin (with doctor guidance), Berberine may provide additional blood sugar benefits — but it carries interaction risks including hypoglycaemia (dangerously low blood sugar) when combined with diabetes medications. Always inform your pharmacist before starting Berberine. Source: PMC · Cardiovascular Diabetology 2024 · Nebraska Medicine 2025.
Quick Answer Use a glucometer (blood glucose meter) — available at most Nigerian pharmacies for ₦3,000–₦15,000. Common brands available in Nigeria include: Accu-Chek (Roche), OneTouch, and Contour. Test strips cost ₦1,500–₦4,000 per pack of 50. Target ranges: fasting blood sugar (before breakfast): 4.0–7.0 mmol/L (72–126 mg/dL). 2 hours after meals: below 10 mmol/L (180 mg/dL). If you cannot afford a glucometer, most private laboratories and some government health centres offer point-of-care blood glucose testing for ₦300–₦1,000. Source: ADA Standards of Care 2024 · NDHS 2023.
Quick Answer Yes — uncontrolled gestational diabetes increases risks for both mother and baby, but with proper management these risks are greatly reduced. Risks to the baby include: large birth size (macrosomia) making delivery difficult, low blood sugar at birth, increased risk of the baby developing Type 2 diabetes later in life. Risks to the mother include: pre-eclampsia, difficult labour, and a 7-fold increased risk of developing Type 2 diabetes after delivery. All pregnant Nigerian women should be screened for gestational diabetes between weeks 24–28 during antenatal care. Source: WHO · NDHS 2023 · FMOH Antenatal Guidelines.
