Glucose

A glucose test is a blood test that measures the level of glucose (blood sugar) in the blood. It is mainly used to detect diabetes or prediabetes, as well as to follow up on people who already have a diabetes diagnosis. By checking your blood sugar, you can detect abnormalities at an early stage and take control of your health.

You should test your blood sugar if you have symptoms such as fatigue, increased thirst, frequent urination, blurred vision or unexplained weight change. People with risk factors such as obesity, high blood pressure, a family history of diabetes or a sedentary lifestyle are also advised to check their glucose levels regularly.

A normal fasting blood sugar is between 4.0–6.0 mmol/L. A fasting value between 6.5–6.9 mmol/L may indicate prediabetes, while a value of 7.0 mmol/L or higher on repeated occasions indicates diabetes. Values ​​may vary slightly depending on the laboratory and individual factors.

High blood sugar, or hyperglycemia, can indicate diabetes or prediabetes. This means that the body does not produce enough insulin or cannot use insulin effectively. If left untreated, high levels can lead to complications such as heart disease, nerve damage, and vision problems.

Yes, low blood sugar, especially below 3.0 mmol/L, can be dangerous. Hypoglycemia causes symptoms such as sweating, palpitations, confusion and, in severe cases, unconsciousness. It is most common in diabetics who take insulin or blood sugar-lowering medications, but can also occur in other medical conditions.

Yes, for a fasting glucose test you need to fast for at least 10 hours before the test. You should only drink water during the fast and avoid food, coffee and other drinks that can affect blood sugar.

Glucose tests measure your current blood sugar level at a specific time, while HbA1c shows your average blood sugar over the past 2–3 months. Both tests are used to diagnose and monitor diabetes, but HbA1c provides a longer-term picture.

Yes, with us you can order a glucose test directly online without the need for a doctor's referral. You will receive a digital referral and can take the blood sample at any connected sampling device. The result will be reviewed by a licensed doctor and you will receive a response within a few days.

Glucose is the body's main source of energy and is needed for cells to function. When you eat carbohydrates, they are broken down into glucose, which is then transported through the blood to the body's cells where it is used as fuel. Glucose is particularly important for the brain, which uses glucose almost exclusively for energy.

In order for glucose to be absorbed by the cells, the hormone insulin is needed, which helps glucose move from the blood into the cells. A balance between glucose and insulin is crucial for the body to have enough energy, without blood sugar levels becoming too high or too low.

Excess glucose is stored as glycogen in the liver and muscles, and when needed, the body can convert it back into glucose. If glucose levels are constantly too high or too low, it can lead to serious health problems such as diabetes or hypoglycemia.

You can lower your blood sugar naturally by making lifestyle changes that improve your body's insulin sensitivity and blood sugar regulation. Here are some effective ways.

• Eat balanced meals: Choose fiber-rich carbohydrates like whole grains, vegetables, and legumes. Avoid fast carbohydrates like sugar and white flour, which quickly raise blood sugar.
• Exercise regularly: Physical activity, especially walking, strength training, or cardio, helps your muscles absorb glucose from your blood and naturally lowers your blood sugar.
• Avoid large meals: Eat smaller portions and avoid overeating, which can cause large blood sugar spikes. Space your meals evenly throughout the day.
• Manage stress: High levels of stress can increase blood sugar by releasing stress hormones like cortisol. Stress management practices such as meditation, yoga, or deep breathing can help.
• Prioritize sleep: Poor sleep negatively impacts insulin and blood sugar. Aim for at least 7–8 hours of sleep per night.

By combining these habits, you can improve blood sugar balance and reduce your risk of type 2 diabetes. Regular follow-up with glucose testing will help you see the impact of your changes.
