How to Tell If Your Blood Sugar Has Risen

Maintaining normal blood sugar levels is an important aspect of health, especially for people with carbohydrate metabolism disorders. Even slight deviations can affect how you feel and your overall health. Innovative CGM technologies, such as the Dexcom G7, simplify glucose monitoring. However, it is also important to recognize the signals your body sends. Understanding these signs will help you take timely action and avoid serious consequences.

Key Signs of High Blood Sugar

Blood glucose levels affect how you feel and your overall health. A sharp rise in this level leads to hyperglycemia. This condition can manifest as both mild symptoms and sudden deterioration in your condition. Key signs include:

• Intense thirst. A dry mouth may also occur.
• Frequent urination. Excess glucose causes the kidneys to work harder to excrete fluid.
• Drowsiness and fatigue. The body’s cells do not receive enough energy because insulin is not functioning properly.
• Dizziness and weakness. Brain function deteriorates due to a lack of energy.
• Blurred vision. High blood sugar causes swelling of the eye’s lens, leading to temporary nearsightedness.
• Headaches. These develop due to dehydration and impaired blood circulation.
• Slow wound healing. Hyperglycemia negatively affects tissue regeneration.
• Itchy and dry skin. Caused by dehydration and impaired skin microcirculation.
• Bad breath. In severe cases, the body breaks down fats, leading to the accumulation of ketones and the development of an acetone-like odor.

The progression of the disease may be gradual, remaining unnoticeable in the early stages. The body attempts to compensate for the imbalances, but over time, characteristic symptoms emerge that indicate a problem. These signs vary depending on age, overall health, and the severity of hyperglycemia. It is important to note that some symptoms may be mild or masked by signs of fatigue, stress, or other illnesses, which makes timely detection of the problem more difficult.

How to Confirm Hyperglycemia

To confirm hyperglycemia, blood glucose levels are measured. The most common method is using a glucometer, which quickly provides results based on a blood sample from a finger prick. However, this method requires regular finger pricks, which isn’t always convenient, especially with frequent monitoring.

Innovative technologies offer more comfortable solutions. For example, continuous glucose monitoring systems, such as the Freestyle Libre sensor, track blood sugar levels without the need for constant finger pricks. Simply scan the sensor on the skin to get the current reading.

For even more accurate and continuous monitoring, the Dexcom G7 is a good choice. This device automatically tracks blood sugar changes in real time and alerts you to critical fluctuations, which is especially important for people with insulin-dependent diabetes.

What to Do If Your Blood Sugar Rises

Hyperglycemia is not just a temporary discomfort, but a signal from the body that its metabolic balance is disrupted. Even if the symptoms seem minor, inaction can lead to a worsening of your condition and the development of dangerous complications, such as diabetic ketoacidosis or hyperosmolar coma. If your glucose level is above normal, take the following steps:

1. Drink water. This will help speed up the elimination of excess sugar.
2. Do some light exercise. Walking or mild physical activity lowers blood glucose levels.
3. Limit your carbohydrate intake. Avoid sugary and high-carbohydrate foods.
4. Monitor your condition. If symptoms of worsening condition appear (vomiting, confusion), seek medical help immediately.

Hyperglycemia can be dangerous, especially in cases of chronic high blood sugar. Regular monitoring and following your doctor’s recommendations will help you avoid serious complications.
