Diabetes as a global widespread disease
Diabetes is one of the most common chronic diseases worldwide and requires regular monitoring of blood sugar levels.
But it's not just the daily blood sugar level that matters: To better understand the diabetes status and the risk of long-term complications, various blood values are important. In this article, we take a closer look at the HbA1c level, blood sugar, and metabolism and show how easy it is to check these values conveniently from home with the help of
This article provides you with an initial overview of HbA1c and blood sugar.For further information, we recommend the article from the Federal Ministry of Health as well as the page of the German Diabetes Foundation.

The HbA1c value: What long-term blood sugar indicates about your blood sugar control
The HbA1c value, also known as long-term blood sugar, reflects your average blood sugar level over the past 2–3 months. Unlike daily fluctuations, it shows the general trend of your blood sugar control and is therefore an essential marker for managing diabetes.
An elevated HbA1c value indicates consistently high blood sugar levels. This increases the risk of diabetes complications such as nerve damage, kidney disease, and eye problems. The target value may vary depending on age and health condition. For many people with diabetes, the ideal HbA1c value is below 7%, but it should be determined individually with a doctor.
Regular checks of the HbA1c value help you stay on track and optimally adjust your diabetes treatment. With the home test from

Blood Sugar: A Daily Indicator of Fluctuations
The blood sugar level indicates how much glucose is currently in your blood. While the HbA1c value reflects the long-term blood sugar trend, the blood sugar test is ideal for monitoring short-term fluctuations – for example, after meals or physical activity.
Healthy blood sugar levels are between 70 and 100 mg/dL when fasting and under 140 mg/dLafter eating. Simple blood sugar tests provide valuable insights into the effects of diet, exercise, and lifestyle on your body.
Regular measurements help to detect signs of insulin resistance or diabetes early and consciously adjust your health decisions.
Metabolism and Insulin: The Key to Understanding Diabetes
A healthy metabolism is crucial for the regulation of blood sugar. The hormone insulin, produced in the pancreas, allows glucose to enter the body's cells from the blood, where it is used for energy production .
In diabetes, this process is disrupted. People with type 1 diabetes have an insulin deficiency, while in type 2 diabetes , the effect of insulin is reduced due to insulin resistance . In both cases, too much glucose remains in the blood because it cannot be efficiently transported into the cells.
Disrupted insulin production or action affects the entire metabolism. In the long term, this can lead to weight gain, fatigue , and other health issues.

FAQ: Frequently Asked Questions about Diabetes and Long-term Blood Sugar
What is the HbA1c value and why is it important in diabetes?
What is the HbA1c value and why is it important in diabetes?
The HbA1c value, also known as the "long-term blood sugar," indicates the average blood sugar level over the past two to three months. It is a key indicator for long-term blood sugar control and the risk of diabetes complications.
How often should the HbA1c level be checked in diabetes?
How often should the HbA1c level be checked in diabetes?
People with diabetes should have their HbA1c levels checked every three to six months. The exact frequency depends on the individual situation and the target value discussed with the doctor.
What does the fasting blood sugar level say about my health?
What does the fasting blood sugar level say about my health?
The fasting blood sugar level indicates the blood sugar level after at least eight hours without food intake. A fasting blood sugar level of 100 to 125 mg/dL suggests prediabetes, while levels of 126 mg/dL or higher may indicate diabetes.
What role does the C-peptide level play in diabetes?
What role does the C-peptide level play in diabetes?
C-peptide is a byproduct of insulin production and provides information about how much insulin the body is still producing. A low C-peptide level may indicate type 1 diabetes, while a high level can occur in type 2 diabetes or insulin resistance.
Why is insulin level an important biomarker in diabetes?
Why is insulin level an important biomarker in diabetes?
The insulin level helps to assess whether the body is producing enough insulin and whether insulin resistance is present. A high insulin level may indicate insulin resistance, while a low level is often found in type 1 diabetes.
What is the difference between Type 1 and Type 2 diabetes in terms of biomarkers?
What is the difference between Type 1 and Type 2 diabetes in terms of biomarkers?
In type 1 diabetes, insulin levels are usually very low because the body produces little or no insulin. In type 2 diabetes, insulin levels are often high because the body develops insulin resistance. The HbA1c value is an important indicator of blood sugar control in both cases.
What is the relationship between blood lipid levels and diabetes?
What is the relationship between blood lipid levels and diabetes?
People with diabetes often have elevated blood lipid levels, such as triglycerides and LDL cholesterol. These values are important biomarkers as they increase the risk of cardiovascular diseases, which are more common in diabetes patients. You can easily check blood lipid levels like cholesterol with our lipid check.
Why is blood pressure particularly relevant in diabetes?
Why is blood pressure particularly relevant in diabetes?
High blood pressure is a common companion of diabetes and increases the risk of strokes, heart disease, and kidney damage. Regular monitoring of blood pressure is therefore very important for people with diabetes.
What role does albumin in urine play in diabetes?
What role does albumin in urine play in diabetes?
Albumin in the urine is an important marker for kidney damage. In diabetes, elevated blood sugar levels can damage the kidneys and lead to increased excretion of albumin, which may indicate diabetic nephropathy.
How are the liver enzyme ALT and diabetes related?
How are the liver enzyme ALT and diabetes related?
The ALT value (alanine aminotransferase) is a liver enzyme that often increases with elevated blood sugar levels. A high ALT value can indicate a fatty liver, which often occurs with type 2 diabetes.
What is the significance of the CRP value in diabetes?
What is the significance of the CRP value in diabetes?
The CRP level is an inflammation marker that can indicate chronic inflammation. An elevated CRP level is often associated with insulin resistance and an increased risk of cardiovascular diseases in people with diabetes.
Can I check my diabetes biomarkers from home?
Can I check my diabetes biomarkers from home?
Yes, many diabetes-related biomarkers such as HbA1c, blood sugar, and blood lipid levels can now be monitored through home tests. These tests allow you to regularly check your health values and respond early to changes.
