Why Is Blood Glucose Elevated?

Glucose is an important substance in our bodies. After the digestion and absorption of food in the human body, some substances are broken down into glucose and enter the blood, resulting in the formation and increase of blood glucose. Under normal conditions, blood glucose levels are maintained within a stable range, and insulin plays a regulatory role in blood glucose. If high blood glucose levels are detected during testing, it is important to take note. Let's explore the reasons for high blood glucose levels below.

After the human body digests and absorbs food, carbohydrates and other substances are broken down into glucose and enter the blood, leading to the formation and increase of blood glucose. Under normal conditions, blood glucose levels are maintained within a stable range, and the primary regulatory function of blood glucose is performed by insulin. Part of the pancreas in the human body is called the islets, which have the function of secreting insulin. When blood glucose levels rise, they stimulate the islets to secrete insulin, which promotes the metabolism and utilization of the elevated blood glucose after eating, thereby reducing blood glucose levels to within the normal range. However, due to various reasons, the secretory function of the islets may be insufficient or the effect of insulin may be weakened, resulting in abnormal metabolism of blood glucose and persistent levels above the normal range. If the body cannot restore this abnormality, diabetes may occur. Elevated blood glucose levels do not necessarily indicate diabetes. If high glucose levels are detected, it is also necessary to consider whether a large amount of glucose was consumed before the test, as this can affect the measurement results.

Basically, there are no foods that are completely prohibited for individuals with elevated blood glucose levels, but it is generally recommended to avoid simple sugars. The main focus should be on controlling the total calorie intake and making dietary choices that are more reasonable. The correct approach in terms of diet should be to maintain a balanced diet, which means including a variety of foods such as grains, meats, eggs, dairy products, vegetables, and fruits within the context of overall calorie control in order to obtain balanced nutrition. It is recommended to consume vegetables with a low glycemic index, such as cucumbers, tomatoes, green vegetables, and celery, as well as fruits like pomelo, kiwi, strawberries, and green apples. Protein sources should be chosen from high-quality options like lean meat, milk, and fish. Whole grains are preferred for staple foods, such as cornmeal, buckwheat noodles, and oatmeal-based buns. However, it is important to be mindful of portion sizes, control calorie intake, arrange meals reasonably with small portions and frequent meals, and adopt a high-fiber, low-salt, low-fat, and low-sugar diet. The specific amounts of food consumed at each meal should be determined by a nutritionist based on individual tolerance and needs. Additionally, it is essential to closely monitor blood glucose levels and engage in appropriate physical activity.
