Blood Sugar Testing: Benefits, Methods, and How to Maintain Healthy Blood Sugar

When it comes to health, there is one thing that is often overlooked yet very crucial: blood sugar. Many people do not realize that poorly controlled blood sugar levels can pose a high risk to health and can even be an early sign of a serious disease such as diabetes.

According to the International Diabetes Federation (IDF), Indonesia ranks fifth among countries with the most people with diabetes, with 19.5 million people living with diabetes in 2021, a number predicted to reach 28.6 million by 2045 *. This issue is a concern for the Indonesian Ministry of Health (Kemenkes), given that diabetes mellitus is regarded as the “mother of all diseases.” Therefore, it is important for us to understand what a blood sugar check is and how it can contribute to a healthy lifestyle and the prevention of cardiovascular disease.

Why Is a Blood Sugar Check Important?

Blood Sugar and Its Role in the Body

Blood sugar, or glucose, is the body’s main source of energy. When we eat food, especially food that contains carbohydrates, the body converts it into glucose, which is then absorbed into the bloodstream.

The hormone insulin, which is produced by the pancreas, plays an important role in regulating blood sugar levels by helping the body’s cells use glucose as a source of energy or store it for later use. The balance between sufficient blood sugar and insulin is very important, because poorly controlled blood sugar levels can be harmful to health.

Normal Blood Sugar Levels

Keeping blood sugar levels within the normal range is very important for health. Based on information from the Indonesian Ministry of Health, normal blood sugar levels for adults are as follows:

• Fasting blood sugar (after not eating for 8 hours): 70 to 100 mg/dL
• Blood sugar 2 hours after eating: less than 140 mg/dL

These ranges may vary slightly depending on individual factors and testing methods. However, it is important to try to keep blood sugar levels within these ranges to prevent more serious health complications.

Health Risks Related to Blood Sugar Levels

Poorly controlled blood sugar levels can lead to two important conditions to watch out for:

• High Blood Sugar (Hyperglycemia): This condition occurs when the level of sugar in the blood exceeds the normal limit. Hyperglycemia can cause symptoms such as increased thirst, frequent urination, and fatigue, and in extreme cases, it can cause serious complications such as diabetic ketoacidosis, which can be fatal if not treated properly. If left for a long time, hyperglycemia increases the risk of developing heart disease, stroke, and nerve damage.
• Low Blood Sugar (Hypoglycemia): Conversely, hypoglycemia occurs when blood sugar levels drop below 70 mg/dL. Symptoms include dizziness, weakness, cold sweats, and shakiness, and in severe cases, it can cause loss of consciousness or seizures. Hypoglycemia is often experienced by people with diabetes who use insulin or blood sugar lowering medicines, but it can also occur in healthy people who do not get enough food.

Types of Blood Sugar Testing Methods

Monitoring blood sugar levels is an important step in maintaining health. Did you know that there are several different methods for checking blood sugar? The following are the various types of blood sugar testing methods, from tests performed in a laboratory to devices you can use at home.

1. Fasting Blood Sugar Test

The fasting blood sugar test is performed after not eating for at least 8 hours. The procedure is quite simple:

• Preparation: The patient is required to fast, which means no food or drink except plain water. This test is usually done in the morning.
• Procedure: A health worker will take a blood sample from a vein, usually in the arm.
• Interpreting the Results: The test results will show the blood sugar level. The normal range for this test is 70 to 100 mg/dL. A result above 100 mg/dL may indicate a disorder of glucose metabolism, while a result above 126 mg/dL suggests possible diabetes.

2. Oral Glucose Tolerance Test

The oral glucose tolerance test is performed to see how the body processes glucose.

• Preparation: Before the test, the patient needs to fast for 8 hours, and is often advised not to eat foods high in carbohydrates for two to three days beforehand.
• Procedure: After an initial blood sample is taken, the patient drinks a glucose solution containing 75 grams of sugar. A second blood sample is taken 2 hours later.
• Interpreting the Results: A result below 140 mg/dL is considered normal. A result between 140 and 199 mg/dL indicates prediabetes, while a result above 200 mg/dL indicates diabetes. This test is usually intended for people at risk of diabetes or pregnant women who need to be checked for gestational diabetes.

3. HbA1c (Hemoglobin A1c) Test

The HbA1c test measures your average blood sugar level over the past 2 to 3 months. This test does not require special preparation, and blood can be drawn at any time. The results give a more stable picture of blood sugar control than daily tests.

A result below 5.7% is considered normal, between 5.7% and 6.4% indicates a risk of diabetes, and 6.5% or higher indicates diabetes. This test is very useful for people with diabetes to monitor how well they are managing their blood sugar levels.

4. Random Blood Sugar Test

The random blood sugar test is done regardless of mealtimes. This test is often used for the initial diagnosis of diabetes. It can also be used in emergencies when symptoms of hyperglycemia or hypoglycemia appear.

The results can be affected by food that has just been eaten, so they do not always give an accurate picture. A result of more than 200 mg/dL suggests possible diabetes, but it needs to be confirmed with other tests.

Where to Get a Blood Sugar Check

Blood sugar checks can be done at various health facilities, including:

1. Clinics and Hospitals: Official places to get tested by trained medical staff. They usually offer more complete services.
2. Laboratories: Some health laboratories offer direct blood sugar testing services.
3. Other Health Facilities: Facilities such as community health centers (puskesmas) or other public health service centers also provide this service.

Equipment for Checking Blood Sugar at Home

To monitor blood sugar at home, several types of equipment are available, including:

• Glucometer: The most commonly used device for checking blood sugar. It requires a small amount of blood taken from a fingertip.
  • Advantages: Practical and easy to use.
  • Disadvantages: Requires a device and test strips, which can be expensive in the long run.
• Continuous Glucose Monitor (CGM): A device attached to the skin that monitors blood sugar continuously.
  • Advantages: Provides real-time data and helps avoid drastic swings in blood sugar.
  • Disadvantages: High cost and requires calibration.

How to Maintain Healthy Blood Sugar

Maintaining healthy blood sugar is important not only for people with diabetes but also for anyone who wants to protect their heart health and prevent chronic disease. Here are some tips for keeping blood sugar levels healthy:

1. Healthy Eating Pattern

Adopting a healthy eating pattern is an important first step in maintaining healthy blood sugar. Choose foods with a low glycemic index, such as whole grains, vegetables, and most fruits, because these foods affect blood sugar levels more slowly.

Portion control is also very important. Avoiding large portions and dividing food into several small meals can help keep blood sugar stable. In addition, it is important to pay attention to your carbohydrate intake. Replace simple carbohydrates, such as white rice and white bread, with healthier complex carbohydrates.

2. Regular Exercise

Exercising regularly has a major positive impact on blood sugar and heart health. Physical activity helps the body use glucose as a source of energy, which can lower blood sugar levels. Various forms of exercise, such as walking, swimming, or cycling, should be done for at least 150 minutes per week. Besides helping control blood sugar, exercise can also improve heart health and lift your mood.

3. Manage Your Weight

Keeping your weight within a healthy range is directly related to blood sugar levels. Excess body weight can increase the risk of insulin resistance, which eventually leads to type 2 diabetes. Therefore, it is important to live a healthy lifestyle, including a good diet and regular exercise, to manage your weight effectively.

4. Manage Stress

Stress can significantly affect blood sugar levels. When we are stressed, the body produces hormones such as cortisol, which can raise the level of sugar in the blood. Effective stress management techniques, such as meditation, yoga, or breathing exercises, can help reduce stress and its negative impact on blood sugar levels. Taking time to relax and enjoy hobbies is also a good way to manage stress well.

5. Get Enough Rest

Quality sleep is very important for overall health, including blood sugar control. Lack of sleep can cause hormonal changes that negatively affect glucose metabolism and increase the risk of diabetes. Try to sleep about 7 to 9 hours every night and create a good sleep routine so that your body gets the rest it needs.

6. Consult a Doctor

Regular consultations with a doctor are very important, especially for people at high risk of blood sugar problems. A doctor can help monitor blood sugar levels, give appropriate dietary advice, and recommend the tests needed to identify problems early. These regular checkups help us understand our health condition and take the steps needed to keep blood sugar stable.

Benefits of Regular Blood Sugar Monitoring

Monitoring blood sugar levels regularly offers many health benefits, both for preventing and for treating various diseases.

1. Health Benefits of Regular Blood Sugar Monitoring

Regular blood sugar monitoring provides various significant health benefits. By measuring blood sugar, people can understand their health condition more clearly and prevent more serious health problems.

Through monitoring, a person can detect changes in blood sugar levels early and take appropriate action before the problem develops further. In addition, consistent monitoring also helps track the body’s response to diet and lifestyle changes, so the necessary adjustments can be made to keep sugar levels within normal limits.

2. How Monitoring Helps in Managing Diabetes and Preventing Complications

For people with diabetes, blood sugar monitoring is key to managing the condition well. By knowing their blood sugar levels regularly, patients can understand the patterns of their blood sugar fluctuations and make adjustments to their medication, diet, and physical activity. This helps prevent diabetes complications, such as nerve damage, heart problems, and vision problems.

According to the American Diabetes Association, proper monitoring can help reduce the risk of diabetes complications and is an integral part of long-term care *.

Common Myths About Blood Sugar Testing

Myth: Only People With Diabetes Need to Check Their Blood Sugar

Many people believe that blood sugar checks are only needed for those who have already been diagnosed with diabetes. In reality, anyone, especially those at high risk, should have their blood sugar checked regularly. Monitoring blood sugar levels can help detect health problems early, so preventive action can be taken before the condition gets worse.

Myth: Blood Sugar Results Are Only Affected by Food Eaten Right Before the Test

Many people assume that blood sugar levels are only affected by food that has just been eaten. In fact, many factors affect blood sugar levels, including physical activity, stress, and sleep quality. This explains why regular checks are very important for getting a more accurate picture of a person’s blood sugar health.

Myth: Blood Sugar Tests Are Very Painful

Some people are reluctant to have a blood sugar test because they are afraid of the pain. However, drawing a blood sample for a blood sugar test uses a very small needle and is quick, so the pain is minimal. The discomfort often lasts only a few seconds, and the benefits of the test far outweigh the brief discomfort.

Myth: A Single Blood Sugar Reading Is Always Accurate

There is an assumption that the result of a single blood sugar test can be taken as a definitive measure of a person’s health. While test results provide useful information, variations can occur depending on the time of the test, the person’s health at that moment, and many other factors. Therefore, it is important to look at the overall history of blood sugar checks and consult a doctor for proper interpretation.

Myth: Sweet Foods Always Raise Blood Sugar

Many people think that only sweet foods raise blood sugar levels. Although foods high in sugar can certainly have an impact, other foods (for example, simple carbohydrates) can also affect sugar levels. The portion size and combination of foods eaten also play a role in blood sugar fluctuations. Understanding the different types of food that can affect blood sugar is very important for good health management.
