What Is A Fasting Blood Sugar Or Fasting Glucose Level
A fasting blood sugar level is the result of a blood sample taken after a patient fasts for at least eight hours. A normal fasting blood sugar level for someone without diabetes is less than 100 mg/dL, or HbA1C below 5.7%. Prediabetes is a fasting blood sugar level from 100 to 125 mg/dL, or HbA1C of 5.7%-6.4%. Diabetes is a fasting blood sugar level of 126 mg/dL and above, or HbA1C of 6.5% or higher. Source:Continue reading > >
Symptoms Of High Blood Sugar Level
Hyperglycemia, often known as high blood sugar, can be brought on by various factors, such as being ill, being under stress, eating more than you intended, and not taking enough insulin.
A persons pancreas secretes more insulin when blood sugar levels are too high. Their pancreas releases glucagon to increase blood sugar levels when they fall. This equilibrium aids in giving the cells enough energy while avoiding damage that persistently elevated blood sugar levels could bring.
Long-term, major health issues might develop from elevated blood sugar over time. High blood sugar symptoms include:
- Incredibly fatigued
- Having visual problems
- A higher need to urinate
Managing your blood sugar can be challenging if you become sick. Your ability to eat and drink may be limited, impacting your blood sugar levels. Use an over-the-counter ketone test kit to screen your urine for ketones if youre sick and your blood sugar is 240 mg/dL or above.
If your ketones are high, call your doctor. High ketones may be a precursor to diabetic ketoacidosis, a medical emergency that requires prompt treatment.

How Can Continuous Glucose Monitoring Help You Maintain Optimal Glucose Levels
It is not uncommon for your glucose levels to increase after a meal: you just ate food that may contain glucose, and now your body is working on getting it out of the bloodstream and into the cells. We know that we want to prevent excessive spiking of glucose levels because studies show that high post-meal glucose spikes over 160 mg/dl are associated with higher cancer rates. Spikes are also associated with heart disease. Repeated high glucose spikes after meals contribute to inflammation, blood vessel damage, increased risk of diabetes, and weight gain. Additionally, the data shows that the big spikes and dips in glucose are more damaging to tissues than elevated but stable glucose levels. Therefore, you should strive to keep your glucose levels as steady as possible, at a low and healthy baseline level, with minimal variability after meals.
Keeping your glucose levels constant is more complicated than just following a list of eat this, avoid that foods. Each person has an individual response to food when it comes to their glucose levels studies have shown that two people can have different changes in their glucose levels after eating identical foods. The difference can be quite dramatic. One study found that some people had equal and opposite post-meal glucose spikes in response to the same food.

Your fasting blood glucose level is the lowest your blood sugar can be because the influence of recent meals is minimized .
Fasting blood sugar is often checked alongside HbA1c , which is a measure of your blood sugar levels over the past three months. The more sugar there is in the blood, the more it will attach to hemoglobin, raising HbA1c .
Taken together, the two offer more information than each test alone. For example, even if your blood sugar levels are very high at one random point, they may have been mostly low over the past couple of months . On the other hand, HBA1c could be higher but your glucose levels at the moment lower.
Apart from diabetes, abnormal levels can point out issues such as insulin resistance, hormonal imbalances, and pancreatic, liver, or kidney disease.
