Blood glucose test is a special procedure, which helps measure the amount of glucose in a usual sample of blood. Being the main source of energy for the organism, blood sugar is inevitable for proper functioning of key body organs, including brain cells. Carbohydrates are the leading ingredients, which can rapidly transform into glucose in the organism. Cereal, pasta, rice, and fruit are the top sources of this element. Therefore, you need to consume much of these products in order to balance glucose levels and prevent diabetic complications.
The main purpose of glucose testing is checking the patient for type 1 or type 2 diabetes as well as gestational diabetes. Normally, the amount of sugar in the blood is controlled by a special hormone called insulin. However, patients diagnosed with diabetes do not produce the sufficient amount of insulin. As a result, sugar starts building up in the blood. If untreated, hyperglycemia can lead to dangerous organ damage. Sometimes, blood testing is used to check a patient for hypoglycemia, which appears in case glucose levels in the blood are drastically low.
Risks Related to Abnormal Glucose Ranges
Blood glucose test is an important procedure that helps people to eliminate serious health problems and prevent abnormal body processes. Besides, serious illnesses and dysfunctions can be detected with the help of the test. The results of the test will depend on numerous factors, including food consumption:
- The results of fasting blood test that vary from 100 to 125 mg/L mean you have prediabetes, which can trigger type 2 diabetes if left unmanaged. If the glucose level is higher than 126 mg/L, you will be diagnosed with diabetes.
- A random glucose test will show diabetes only if blood sugar level is higher than 200 mg/L.
Apart from it, advanced ranges of sugar in the blood can appear if a patient is diagnosed with any of the following conditions:
- Pancreatic cancer;
- Overactive thyroid gland;
- Underactive thyroid or adrenal gland;
- Pancreas tumor;
- Stress caused by heart attack, stroke, surgery or trauma.
Considering the risks of taking blood sugar testing, it is important to mention fainting, abnormal bleeding, lightheadedness, infection or hematoma.
Why You Need to Test Blood Glucose Levels Regularly
The reasons for the frequently recommended blood testing may be numerous, depending on the peculiarities of a patient’s health state. However, most commonly, doctors usually prescribe regular tests to monitor the state of people with diabetes. However, there are many other instances, when a blood sugar test may be required, including:
- Frequent urination;
- Fainting spells;
- Vision impairments;
- Serious weight gain and others.
