Diabetes: How to Check Your Blood Glucose Level | NHS
Monitoring blood glucose levels is an essential part of managing diabetes. Maintaining optimal blood glucose levels can prevent complications and improve the quality of life. The NHS recommends regular checks to keep your diabetes in control. This guide will inform you on how to perform these checks effectively.
Why Check Blood Glucose Levels?
Regular monitoring helps you understand how food, exercise, and medication affect your glucose levels. By keeping track, you'll be able to make informed decisions about diet and exercise. This can greatly reduce the risk of complications such as cardiovascular disease, neuropathy, and retinopathy.
When to Check Blood Glucose Levels
The timing and frequency of glucose checks can vary based on your individual treatment plan. Generally, those with Type 1 diabetes may need to check their levels multiple times a day, while those with Type 2 diabetes might need less frequent checks. Common times to check include:
- Before meals
- After meals
- Before and after exercise
- Before bedtime
- When you feel unwell
Types of Blood Glucose Meters
There are various types of blood glucose meters available. The most common include:
- Standard blood glucose meters
- Continuous glucose monitors (CGMs)
- Flash glucose monitoring systems
Each type has its own advantages and specific instructions for use. It's important to choose a device that fits your lifestyle and is easy for you to use.
Steps to Check Your Blood Glucose Levels
- Wash your hands thoroughly to ensure accurate readings.
- Prepare your kit: Gather your meter, test strips, and a lancing device.
- Insert a test strip into the meter.
- Use the lancing device to prick the side of your fingertip to get a drop of blood.
- Touch the edge of the test strip to the drop of blood and wait for the meter to process the reading.
- Record your reading, including the time and date.
Interpreting Results
The NHS recommends the following target blood glucose levels for most adults with diabetes:
- Before meals: 4 to 7 mmol/L
- After meals: less than 9 mmol/L
Your healthcare provider may provide a different target range tailored to your needs. If your readings are consistently outside your target range, consult your healthcare provider for advice on adjusting your management plan.

Blood glucose monitoring involves regularly testing the level of glucose in your blood. It helps you manage diabetes by providing information on how various factors affect your blood glucose levels.
Checking blood glucose levels helps you manage your diabetes, avoid complications, and make informed decisions about your diet, exercise, and medication.
For most people with diabetes, the target blood glucose levels are: 4 to 7 mmol/L before meals and under 9 mmol/L 2 hours after meals.
The frequency of testing varies depending on your treatment plan and the type of diabetes you have. Typically, you may need to check your levels several times a day.
You need a blood glucose meter, test strips, a lancet device, and lancets to check your blood glucose levels.
Wash your hands, insert a test strip into the meter, use the lancet device to prick your finger, squeeze out a drop of blood onto the test strip, and wait for the meter to display your blood glucose level.
If your blood glucose levels are too high, you may need to adjust your medication, diet, or exercise routine. Contact your healthcare provider for guidance.
If you experience low blood glucose (hypoglycaemia), consume fast-acting carbohydrates like glucose tablets or juice. Recheck your levels after 15 minutes and seek medical advice if necessary.
Yes, stress can affect your blood glucose levels by releasing hormones that can increase blood glucose. Managing stress through relaxation techniques and physical activity can help.
Carbohydrates, protein, and fat can all impact blood glucose levels. Monitoring your diet and understanding how different foods affect your levels is crucial.
Yes, some glucose meters allow for alternative site testing (e.g., forearm, palm). However, fingertip testing usually provides more accurate and timely results.
It is generally not recommended to reuse lancets as it can lead to infections and cause the needle to become blunt, making testing more painful.
Factors such as expired test strips, improper storage of supplies, unclean hands, and insufficient blood sample size can cause inaccurate readings.
Yes, keeping a record of your blood glucose levels can help you and your healthcare provider manage your diabetes more effectively.
A CGM can provide real-time glucose readings without finger-pricks. However, you may still need to do occasional finger-prick tests to ensure accuracy and calibrate the CGM.

You need a special tool to check your blood sugar. This tool is called a blood glucose meter. You also need test strips, a small needle tool called a lancet device, and tiny needles called lancets.
Here are some helpful ideas:
- Use pictures: Look for images of the items. Seeing pictures can help you understand each part.
- Ask for help: A grown-up can show you how to use these tools.
Let's clean our hands first. Put a test strip into the meter. Use a small needle to gently poke your finger. Press on your finger to get a drop of blood. Put the drop of blood on the test strip. Now, wait for the meter to show your blood sugar level.
If your blood sugar is too high, you might need to change your medicine, the food you eat, or how much you exercise. Talk to your doctor or nurse to find out what to do.
If your blood sugar gets too low, eat or drink something sweet. You can have special sugar tablets or a small glass of juice. Check your blood sugar again after 15 minutes. If you still feel unwell, talk to a doctor.

- Wash your hands before testing.
- Make sure you use enough blood for the test.
Yes, writing down your blood sugar levels can help you and your doctor take care of your diabetes better.
A CGM is a device that can check your sugar levels without needing to prick your finger. But sometimes, you might still need to do a finger prick test to make sure the CGM is working correctly and giving the right readings.
