Diabetes is a long-term health condition that affects how the body regulates blood sugar, also known as blood glucose. It is an important health concern in Nigeria, and many people may have diabetes without knowing it because the early symptoms can be mild or difficult to recognise.
Knowing the early warning signs of diabetes in Nigeria, understanding blood sugar testing, and following appropriate medication advice can help people identify the condition early and reduce the risk of complications.
According to the World Health Organization, diabetes can damage the heart, kidneys, eyes, nerves and blood vessels when blood glucose remains poorly controlled. Early diagnosis and consistent management are therefore essential.

What Is Diabetes?
Diabetes develops when the body does not produce enough insulin or cannot use insulin effectively. Insulin is a hormone that helps glucose move from the bloodstream into the body’s cells, where it is used for energy.
The main types include:
Type 1 diabetes: The body produces little or no insulin, so insulin treatment is essential.
Type 2 diabetes: The body does not use insulin effectively and may eventually fail to produce enough. This is the most common type.
Gestational diabetes: High blood glucose develops during pregnancy and requires appropriate medical monitoring and care.
Although type 2 diabetes is associated with factors such as genetics, age, excess body weight and physical inactivity, it can also affect people who are not overweight. Diabetes should never be ruled out based on appearance alone.

Early Warning Signs of Diabetes in Nigeria
Recognising the early signs of diabetes can help you seek medical attention before complications develop. Common symptoms include:
Frequent urination: Needing to urinate more often than usual, including during the night.
Excessive thirst: Feeling thirsty even after drinking water.
Increased hunger: Feeling hungry more frequently than normal.
Unexplained weight loss: Losing weight without deliberately changing your diet or exercise routine.
Persistent tiredness: Feeling unusually weak or exhausted.
Blurred vision: Experiencing changes in your ability to see clearly.
Slow-healing wounds: Cuts and sores that take longer than expected to heal.
Recurring infections: Repeated skin or other infections.
Type 2 diabetes can develop gradually, and some people experience few or no noticeable symptoms for years. This is why blood sugar screening is important, particularly for people with risk factors such as a family history of diabetes, high blood pressure, excess weight or a history of gestational diabetes

When should you seek urgent medical attention?
Seek emergency care if suspected diabetes is accompanied by vomiting, abdominal pain, rapid or difficult breathing, confusion, severe dehydration or loss of consciousness. These can indicate a dangerous diabetes-related emergency, including diabetic ketoacidosis.
Do not wait for a routine appointment if these symptoms occur.
Blood Sugar Testing in Nigeria: How Is Diabetes Diagnosed?
A blood sugar test measures the amount of glucose in your blood. Testing is important because symptoms alone cannot confirm whether someone has diabetes.
Healthcare professionals may recommend one or more of the following tests.
1. Fasting blood glucose test
A fasting blood glucose test measures blood sugar after you have gone without food or caloric drinks for at least eight hours, usually overnight. Water is generally permitted.
A fasting plasma glucose result of 126 mg/dL (7.0 mmol/L) or higher is within the diabetes diagnostic range. In people without clear symptoms, the result generally needs confirmation with repeat testing or another appropriate test.
2. Random blood glucose test
A random blood glucose test can be performed at any time, regardless of when you last ate. A result of 200 mg/dL (11.1 mmol/L) or higher, together with classic diabetes symptoms, can support a diagnosis. A healthcare professional will determine whether further testing is necessary.
3. HbA1c test
The HbA1c test estimates average blood glucose over approximately the previous two to three months. An HbA1c result of 6.5% or higher is within the diabetes diagnostic range when measured using an appropriate standardised test.
Certain conditions, including some forms of anaemia and disorders affecting red blood cells, can affect the accuracy of HbA1c results.
These thresholds are diagnostic guidelines, not a substitute for professional assessment.
How can you monitor blood sugar at home?
If you have been diagnosed with diabetes, your healthcare professional may recommend a home blood glucose meter. The device measures a small blood sample, usually obtained from a fingertip, and displays the result.
To use a meter safely:
-
Wash and dry your hands before testing.
-
Insert a compatible, unexpired test strip.
-
Use the lancing device according to its instructions.
-
Apply the blood sample as directed.
-
Record the result, date and time, along with relevant information such as meals or medication.
-
Follow your healthcare professional’s advice on how often to test.
Not everyone with diabetes needs to test at the same frequency. Monitoring needs depend on the type of diabetes, medicines used and individual treatment plan.
Diabetes Medication Management: What You Need to Know
Diabetes medication helps control blood glucose and reduce the risk of long-term complications. The appropriate treatment depends on the type of diabetes, glucose levels, other health conditions and individual needs.
Common diabetes medicines
-
Metformin: Commonly prescribed for type 2 diabetes. It helps reduce glucose production by the liver and improves the body’s response to insulin.
-
Other oral medicines: Depending on the patient’s circumstances, a clinician may prescribe medicines from classes such as SGLT2 inhibitors or sulfonylureas.
-
Insulin: Essential for people with type 1 diabetes and sometimes required for people with type 2 diabetes or diabetes during pregnancy.
Never start, stop or change a diabetes medicine without consulting your healthcare professional. Do not share prescription medicines with another person, and ask your pharmacist about possible side effects and interactions
Tips for managing diabetes medicines safely
Take medicines at the prescribed times and doses.
Understand what to do if you miss a dose; ask your pharmacist rather than doubling the next dose automatically.
Store medicines and insulin according to the manufacturer’s instructions.
Keep follow-up appointments and review your blood sugar results with your healthcare professional.
Learn to recognise low blood sugar, especially if you use insulin or certain glucose-lowering medicines.
Shaking, sweating, dizziness, sudden hunger and confusion can indicate low blood sugar. If you are conscious and able to swallow safely, follow your clinician’s recommended hypoglycaemia treatment plan. Severe confusion, seizures or unconsciousness require emergency assistance; never give food or drink by mouth to an unconscious person.
Lifestyle Changes That Support Diabetes Management
Medication is only one part of diabetes care. Healthy daily habits can help improve glucose control and reduce the risk of complications.
Eat balanced meals: Include vegetables, beans, whole grains and appropriate portions of protein. Pay attention to portion sizes of rice, yam, garri and other carbohydrate-rich foods.
Limit sugary drinks: Reduce soft drinks, sweetened beverages and excessive added sugar.
Stay physically active: Aim for regular activity suited to your health and abilities. Many adults benefit from at least 150 minutes of moderate activity weekly, when medically appropriate.
Attend regular check-ups: Monitoring blood pressure, kidney function, eyes and feet can help detect complications early.
Avoid smoking: Smoking increases cardiovascular risks, which are already elevated in people with diabetes.
These measures can help manage type 2 diabetes, but they do not replace necessary medication or insulin.

Frequent urination, excessive thirst, increased hunger, unexplained weight loss, fatigue and blurred vision are common warning signs. Some people have no symptoms.
2. Where can I check my blood sugar in Nigeria?
You can enquire at a hospital, clinic or pharmacy offering blood glucose testing. Confirm test availability and whether laboratory testing is required for diagnosis.
3. Can diabetes be managed without medication?
Some people with type 2 diabetes can improve their glucose levels through lifestyle changes, but others need medication or insulin. Never stop prescribed treatment without medical guidance.
4. How often should I check my blood sugar?
The recommended frequency depends on your treatment, glucose control and risk of low blood sugar. Follow an individual monitoring plan from your healthcare professional.
