Understanding Blood Sugar Levels
Blood sugar levels, or blood glucose levels, indicate the glucose content in your blood from food. These levels tend to fluctuate more in individuals with diabetes than in those without the condition.
Monitoring Blood Sugar Levels
Regular monitoring of blood sugar levels through finger-prick tests or continuous glucose monitoring helps you grasp your levels and effectively manage your daily activities and treatment.
The HbA1c blood test measures average blood sugar levels over three months for all diabetes patients.
The Importance of Regular Checks
Regular blood sugar checks are essential for diabetes patients on certain medications to manage hypo and hyper episodes. Monitoring helps you understand your body and avoid serious complications.
Identify patterns and record results to assist your healthcare team in customizing your care plan for optimal health.
Types of Monitoring Devices
Continuous Glucose Monitors
CGMs are increasingly favored for blood sugar monitoring without the need for finger pricks. These sensors offer continuous readings of interstitial fluid sugar levels.
Even with a CGM, it is important to have a blood glucose meter for accurate readings. Stay informed about your levels to prevent complications and maintain overall health.
Finger-Prick Testing
Finger-prick tests provide immediate blood sugar level readings. Learn the correct testing techniques and seek support from others if needed.
Maintaining optimal blood sugar levels is essential for averting diabetes complications in the present and future.
Below is a helpful guide to assist you in determining your target blood sugar range:
For children with type 1 diabetes:
- Upon waking up and before meals: 4 to 7mmol/l
- After meals: 5 to 9mmol/l
For adults with type 1 diabetes:
- Upon waking up and before meals: 5 to 7mmol/l
- Before meals at other times of the day: 4 to 7mmol/l
- After meals: 5-9mmol/l at least 90 minutes after eating
It is crucial to agree on a bedtime target with your healthcare team as well.
For individuals with type 2 diabetes:
Currently, there are no specific NICE recommendations for blood sugar targets for type 2 diabetes. It is vital to discuss your individual blood sugar targets with your healthcare team if you have type 2 diabetes. You can refer to our HbA1c page for information on HbA1c targets in type 2 diabetes, and our Time in Range page for details on target ranges.
For pregnant women with any form of diabetes, including gestational diabetes:
- Fasting: below 5.3mmol/l
- One hour after meals: below 7.8mmol/l
- If you can only check two hours after a meal, aim for below 6.4mmol/l
- Pregnant women should maintain blood sugar levels above 4 mmol/l
Keep in mind that your personal target range for blood sugar levels may vary. Your healthcare team will work with you to define these targets in order to minimize risks for yourself and your baby.
If you are planning to conceive or are currently pregnant, we have a wealth of information to support you.
What happens when your blood sugar levels are too low?
If your blood sugar levels drop too low, typically below 4 mmol/l, you may experience a hypo. Hypos require immediate treatment to prevent a further decline in blood sugar levels, which could lead to a severe hypo necessitating emergency intervention.
Since there are various symptoms of a hypo, it is essential to recognize the signs if your blood sugar level decreases significantly. We also offer additional information on how to manage a hypo.
What happens when your blood sugar levels are too high?
When your blood sugar levels slightly exceed your targets, there are usually no noticeable symptoms. However, if your blood sugar levels become excessively high, you may experience symptoms associated with hyperglycemia.
The threshold at which symptoms manifest differs for each individual, but common signs include increased urination, excessive thirst, headaches, and feelings of fatigue and lethargy.
Knowing how to address hyperglycemia is crucial to prevent the development of ketones in the blood.
