How to Self-Test Blood Sugar

Introduction
In general, individuals can monitor their blood glucose levels at home through methods such as fingertip blood glucose testing, blood sampling from the palm area, continuous glucose monitoring systems, urine glucose testing, and glycated hemoglobin (HbA1c) testing. Patients are advised to choose an appropriate testing method based on their individual circumstances and medical recommendations, and to regularly visit a hospital for venous blood glucose testing to calibrate their self-monitoring results.

Generally, blood glucose can be self-tested using methods such as fingertip blood glucose testing, palm blood sampling, continuous glucose monitoring systems, urine glucose testing, and glycated hemoglobin testing.

1. Fingertip Blood Glucose Testing: First, disinfect the fingertip with an alcohol swab. After allowing the alcohol to evaporate completely, load the lancet into the lancing device and adjust the penetration depth. Firmly press the lancing device against the side of the finger, press the button to obtain a blood sample, and gently touch the blood droplet to the sampling area of the test strip. Once the blood is automatically drawn into the test strip, the glucose meter will automatically count down and display the blood glucose value.

2. Palm Blood Sampling: After disinfection, use a dedicated lancing device or lancet to collect blood from the palm area. Place a drop of the collected blood sample onto the blood glucose test strip and insert the strip into the glucose meter for testing to obtain the blood glucose value.

3. Continuous Glucose Monitoring System: A continuous glucose monitoring system consists of a glucose sensor, transmitter, and receiver. During use, the current glucose level, glucose fluctuation trends, and historical glucose data can be viewed anytime via the receiver.

4. Urine Glucose Testing: Collect a clean midstream urine sample. Immerse the urine glucose test strip into the urine, then remove it and wait for the specified time. Compare the color of the test strip with the color chart on the test strip packaging to determine the approximate level of glucose in the urine.

5. Glycated Hemoglobin Testing: Glycated hemoglobin testing instruments generally use fingertip capillary blood or venous blood as the sample. Collect the required amount of blood according to the instrument instructions, and mix it with the testing reagent to allow the reaction to occur. This test helps patients understand their long-term blood glucose control status.

There are various methods for blood glucose testing. Patients are advised to choose an appropriate testing method based on their individual circumstances and medical advice, and to periodically visit a hospital for venous blood glucose testing to calibrate self-test results.

Are high blood pressure and high blood sugar indicative of diabetes?
In general, whether high blood pressure and high blood sugar indicate diabetes depends on the specific circumstances. If blood glucose levels do not meet the diagnostic criteria for diabetes but are only slightly elevated, it usually does not constitute diabetes. However, if blood glucose meets the diagnostic criteria for diabetes, a diagnosis of diabetes can be made even in the presence of high blood pressure, and standardized intervention is required. To control blood glucose and blood pressure, it is important to reduce intake of high-sugar foods in daily life.

What items should be included in a physical examination?
Core components of a routine physical examination generally include complete blood count (CBC), liver and kidney function tests, chest imaging, abdominal ultrasound, as well as blood pressure and blood glucose measurements. By analyzing indicators such as red blood cells, white blood cells, and platelets in the blood, this examination helps identify conditions like anemia, infection, or abnormal coagulation, serving as a fundamental assessment of basic health status.

What does drinking water before a physical examination affect?
Drinking water before a medical examination may generally affect blood tests, abdominal ultrasound, urinalysis, gastrointestinal examinations, and blood glucose measurements. Consuming large amounts of water can dilute the blood, potentially leading to lower levels of hemoglobin and hematocrit, which may interfere with the assessment of conditions such as anemia. It may also slightly reduce the measured values of blood lipids and glucose.

What are the CT findings of cerebral infarction?
Cerebral infarction is a disease caused by impaired blood supply to the brain, leading to ischemia, hypoxia, and necrosis of brain tissue. CT imaging is a commonly used method for diagnosing cerebral infarction. CT findings vary depending on the stage of the disease and mainly include low-density lesions, lesion location, morphological characteristics, mass effect, and early specific signs. It is important in daily life to control blood pressure, blood glucose, and lipid levels, and to quit smoking and limit alcohol consumption.

How to prevent pancreatitis
To prevent pancreatitis, it is important to control alcohol consumption, adjust diet, treat underlying biliary diseases, manage blood glucose levels, and avoid drug abuse. If symptoms such as persistent upper abdominal pain, nausea, or vomiting occur, prompt medical attention is recommended. Alcohol is a major contributing factor in triggering pancreatitis; long-term heavy drinking can directly damage pancreatic cells, so strict control is necessary.

Should patients with chronic pancreatitis follow a low-sugar diet?
In general, whether patients with chronic pancreatitis need a low-sugar diet depends on their blood glucose levels. Patients without abnormal glucose metabolism do not require a strict low-sugar diet; controlling total caloric intake is sufficient. However, if blood glucose elevation or diabetes is present, a low-sugar diet should be maintained. The daily diet for patients with chronic pancreatitis should primarily be low-fat and easily digestible, with regular meal times and avoidance of overeating.

How to manage blood glucose control after pancreatectomy
After pancreatectomy, insufficient insulin secretion may occur, requiring insulin use as directed by a physician. Dosage and injection frequency should be adjusted according to blood glucose levels to maintain glucose within a reasonable range, avoiding significant fluctuations caused by self-adjusting the dose. Choose low-sugar, high-fiber foods rich in high-quality protein, control carbohydrate intake, and avoid sweets and refined grains such as white rice and flour products that can rapidly raise blood sugar.

Can patients with gallstones eat oranges?
In general, patients with gallstones can eat oranges, as long as they do so in moderation. It is important to control the amount consumed—eating too many at once should be avoided to prevent excessive sugar intake and added strain on the body. Fresh oranges should be chosen. Patients with abnormal blood glucose levels should carefully consider their individual condition before consuming oranges. If abdominal discomfort, pain, or other symptoms occur after eating oranges, medical attention should be sought promptly.
