"Which food is better for me?"
Look at your line after eba and egusi. Then look at it after beans and plantain. Show your doctor what you see.
For people with sugar problems, and their families
I wear a sensor that checks my sugar 24/7 because health is wealth.
Now I get a clearer picture of how my sugar responds to each meal. A finger-prick checks your sugar 1 time. A small sensor on your arm checks it all day and all night, and shows the result on your phone.

24 hours
A CGM checks your sugar all day and all night, even when you sleep.
↗ ↘
Arrows tell you if your sugar is going up, going down or not moving.
mg/dL
This is how sugar is measured in Nigeria. For example: 123 or 180.
Lesson 1 · The basics
What is a sugar level?
When you eat, your body changes the food into sugar. This sugar is called glucose. Your blood carries it round your body. It gives you energy to walk, think and play. Your sugar level tells you how much glucose is in your blood now.
Easy way to remember
Too little sugar makes you weak, shaky and confused. Too much sugar for a long time can damage your eyes, kidneys, nerves and heart. The aim is to keep your sugar in the middle, not too low and not too high.
What makes your sugar go up or down?
↑ Makes it go up
Food and drinks
Rice, bread, yam, garri, sweet drinks and malt all push sugar up. A big plate pushes it up more than a small plate.
↓ Makes it go down
Moving your body
Walking, climbing stairs, dancing and sweeping the house help your body use up sugar.
↓ Makes it go down
Sugar medicine
Insulin (an injection) and some tablets bring sugar down. Too much medicine, or no food after taking it, can make sugar drop too low.
↑ Can push it up
Worry and sickness
Fever, infection and stress can push sugar up, even when you eat the same food.
↕ Up or down
Sleep
Not sleeping well can make your sugar harder to control the next day.
↕ Up or down
Alcohol
Some drinks push sugar up first. Later, alcohol can make sugar drop too low, often at night.
Next, let's learn what the numbers mean.
See the Number Guide
Lesson 2 · Your numbers
What does my number mean?
This table shows the sugar groups used to read your BioCova CGM numbers. Your doctor may give you different numbers. Always follow your doctor.
| Group | mg/dL | What it means | mmol/L |
|---|---|---|---|
| Very low | below 54 | Danger. Act now. | below 3.0 |
| Low | 54 – 69 | Too low. Take something sweet quickly. | 3.0 – 3.8 |
| Safe zone | 70 – 180 | Good. This is where you want to be. | 3.9 – 10.0 |
| High | 181 – 250 | Too high. Keep watching. | 10.1 – 13.9 |
| Very high | above 250 | Talk to your doctor. | above 13.9 |
Some machines from abroad use mmol/L. To change mmol/L to mg/dL, multiply by 18. Example: 6.8 × 18 = 123 mg/dL.
Time in range
"Time in range" means how long your sugar stayed in the safe zone of 70–180 mg/dL. Many adults with diabetes try to stay there for more than 70% of the day. That is about 17 hours out of 24.
Always follow the numbers your doctor gives you.
Try it: type a number
This is only for learning. It cannot tell you if you are sick. Follow your doctor's advice.
One number helps. A whole day of numbers helps much more.
Finger-prick vs CGM
Lesson 3 · Two ways to check
Finger-prick test vs CGM
Both are good. But they do different jobs.
Finger-prick meter
- Shows your sugar only at the moment you test
- You prick your finger and use a new strip every time
- Cannot see what happens between tests or while you sleep
- Checks sugar straight from your blood
- Still useful when a CGM number does not match how you feel
CGM (Continuous Glucose Monitor)
- "Continuous" means it never stops. It checks again and again, day and night
- One small sensor stays on your arm for 14 days
- Shows how food, work and sleep change your sugar
- Shows arrows: going up, going down or steady
- Makes reports you can show your doctor
Easy way to remember
A meter gives you one number. A CGM tells you the full story: where your sugar was going, and why.
Be careful of "no-needle" sugar watches and rings
Some adverts say a watch or ring can check your sugar without touching your blood. Scientists are still working on this. It does not work well yet. For now, the safe ways are a finger-prick meter or a sensor that sits just under the skin.

Learn to Read the Graph
Lesson 5 · Reading the graph
How to read a CGM graph
This is an example of one day. The line is your sugar. The green band is the safe zone. Follow the numbers 1 to 4.
- 1
Steady at night
The line is flat and inside the green band while you sleep. That is good.
- 2
Small rise after breakfast
Sugar goes up after you eat. Then it comes down again in about 2 hours.
- 3
Too high after a big lunch
The line goes above 180. A big plate of rice or swallow can do this. Write down what you ate.
- 4
Back in the safe zone
A short evening walk and a smaller dinner help bring the line back into the green band.
| Arrow | What it means | What to do |
|---|---|---|
| ↑ | Going up fast | Your sugar is rising quickly. This often happens after food. |
| ↗ | Going up | Rising slowly. |
| → | Steady | Not moving much right now. |
| ↘ | Going down | Falling slowly. Be careful if you are already close to 70. |
| ↓ | Going down fast | Falling quickly. Your sugar may soon be too low. Notice how you feel. |
To see exactly how your BioCova CGM shows the arrows, read the instructions in the box.
Numbers are important. How you feel is important too.
Learn the Danger Signs
Lesson 6 · Stay safe
Signs of low and high sugar
Learn these signs. They can help you, your parents or anyone at home.
Low sugar below 70 mg/dL
- Shaking
- Sweating, with cold skin
- Heart beating fast
- Feeling very hungry suddenly
- Feeling dizzy, confused or angry
What to doQuickly take something sweet, like glucose tablets, a small cup of juice or a normal (not diet) soft drink. Check again after 15 minutes. If the person is confused, cannot swallow or faints, get emergency help at once.
High sugar above 180 mg/dL
- Feeling very thirsty
- Urinating (peeing) a lot
- Feeling tired and weak
- Blurry eyes
- Headache
What to doDrink water. Take your medicine the way your doctor said. Check again later. If it stays very high, or the person is vomiting or breathing fast, go to the hospital quickly.
A CGM can warn you early, sometimes before you feel anything. But it does not replace your doctor or the hospital.
Lesson 7 · Real life
How people use a CGM every day
Long traffic
"Why is my sugar high in traffic?"
Sitting for hours, stress and eating breakfast late can all push sugar up. Now you can see it happen.
Night work
"I work at night"
Nurses, security guards and early-morning traders can see how their working hours change their sugar.
Looking after Mum or Dad
"I want to know they are okay"
Many days of readings give the family and the doctor real facts, not guesses.
Food diary · Lunch
- Amala
- Ewedu & gbegiri
- Fish
- Portion: small wrap
Before: 110 mg/dL2 hours after: 160 mg/dL
Keep a simple food diary
A food diary is a small notebook where you write what you eat. The CGM shows what happened to your sugar. The diary shows why. Together, they help you and your doctor choose the right food for you.
- Write what you ate and how much.
- Write your sugar number before eating and 2 hours after.
- Next time, eat a smaller plate of the same food. Compare the two lines.
- Take the diary and your CGM report to the hospital on your next visit.
The numbers on the diary page are only an example.
Do you look after a parent who lives far away?
See Family Care
Lesson 8 · Caring from far away
Mum and Dad at home. You far away.
Many of us live in a different city or country from our parents. A CGM helps the whole family know what is happening with their sugar every day, not only on hospital day.
At home in Nigeria
Your parent wears the sensor
Mum or Dad wears the small sensor on the arm. They see their own sugar on a phone that works with it.
In Lagos or Abuja for work
You check from the city
Instead of just asking "How is your sugar?", you can talk about the real numbers together.
In London, Houston or Toronto
You order from abroad
Order from anywhere in the world. We deliver to your parent's house in Nigeria. We call you first to confirm everything.

Lesson 9 · How a CGM works
Four easy steps
Put it on
Use the applicator (the tool in the box) to put the small sensor on the back of your upper arm. A tiny needle places a very thin, soft thread under the skin. Then the needle comes straight back out. Only the soft thread stays.
Wear it
Keep it on day and night for 14 days. It checks the water around your cells, not your blood. So you don't need to prick your finger for every reading.
Check it
Open the app on your phone, or use the reader. You will see your number, the arrow and the graph.
Learn from it
Look back over many days. Find patterns. Show the report to your doctor.
No needle stays in your skin
Many people worry about this, so here is the truth. The needle is only used for one second, to put the sensor on. It comes back out with the applicator in the same click. For the 14 days, only a very thin, soft, bendy thread stays under your skin. It is very thin and soft, and most people forget it is there. After 14 days, you peel the sensor off and the thread comes out with it.
Yes, you can bathe with it
The CGM sensor marketed by BioCova is made to stay on while you bathe. Before swimming or going under water, check the water limit in the instructions in the box. After bathing, gently pat the sensor dry with a towel. Do not scrub over it. On hot or sweaty days, a Protective Sensor Patch helps it stay on.
Good to know: A CGM is about 5 to 15 minutes behind a finger-prick test. So it is best for showing where your sugar is going. When sugar is changing fast, the two numbers may be a little different. If you feel unwell and the number looks wrong, do a finger-prick test. Always follow the instructions in the box.

Questions people ask
Will I still need to prick my finger?
Sometimes. Do a finger-prick test if you feel unwell and the CGM number looks wrong, if your sugar is changing fast, or if the instructions in the box tell you to.
Is there a needle in my skin for 14 days?
No. A tiny needle is used only to put the sensor on, and it comes straight back out in the same click. For the 14 days, only a very thin, soft, bendy thread stays under your skin. When you remove the sensor after 14 days, the thread comes out with it.
Does it hurt to put on the sensor?
Most people feel a quick press or small pinch. The thread under the skin is very thin and soft. Many people forget it is there after a short time.
How long does one sensor last?
14 days. After that, you change it for a new one. Follow the instructions in the box.
How much is delivery, and when do I pay?
Delivery is free anywhere in Nigeria. You pay when the kit gets to you. If you order from abroad for your parent, we will agree how you pay when we call you.
Can I bathe with it?
Yes. The CGM sensor marketed by BioCova is made to stay on while you bathe. Before swimming or going under water, check the water limit in the instructions in the box. After bathing, pat it dry gently. Do not scrub over it.
Can I play sports with it?
Yes. The sensor is made for everyday life, including sports and exercise. On hot or sweaty days, a Protective Sensor Patch helps it stay on.
Do I need a smartphone?
You need a phone or reader that works with the sensor. Ask us to check your phone before you order.
Can I order from abroad for my parents in Nigeria?
Yes. In the order form, choose "I live abroad". Add your parent's name, phone and town. Then press Place My Order. We will call you to confirm before we send anything.
Can I see my parent's sugar on my phone?
If the sensor and app can share, your parent can invite you from their app. You both need a phone that works with it, internet, and your parent must agree. Ask us to check before you order.
Is a CGM only for people with diabetes?
Mostly, yes. Diabetes is when the body cannot control its sugar well. If you do not have diabetes, ask a doctor if a CGM is useful for you.
Does BioCova make the CGM?
No. BioCova.com sells and delivers the CGM. The maker's details and instructions are inside every box.
