What Does a High Glucose Level Mean?
What does high glucose level mean? The good news is that is does not necessarily mean that the person with a high glucose reading has diabetes and will have to live with this all the life long, but paying attention to this issue is absolutely necessary. You may have to lower high glucose foods consumption. The best option is switch to low glycemic diet so as to normalize you high glucose levels and prevent insulin resistance and diabetes, which may be not so far ahead.
First of all, blood glucose levels change over the day, the reading depends on when your do the test and other factors, such as as having stress, illness, hormone level changes, alcohol and exercise. When did you have your blood tests and how did you have it measured?
- Fasting blood glucose test taken after you have not eaten for 8-12 hours should not he more than 100 mg/dL.
- The highest glucose level 2 hours after meal not exceeding 130 is appropriate.
- Having 180-200 reading usually means that you have diabetes. Higher glucose levels and having these high glucose symptoms mean that you need to see your doctor and have a A1C test.
- High glucose in urine does not necessarily indicate high blood glucose: you may have low renal threshold for glucose, which means that some sugar gets into your urine even when the blood sugar is still normal. Low renal threshold is not a diabetes herald or symptom.
There are different approaches to measuring blood glucose levels and there is a lot of debate which of them are more accurate and informative. Here, we'll dwell on A1C test, the most widely used test. A1C measures your average blood glucose levels over the last three month, regardless of what and when you've been eating. You'll have to take finger pricks for at least 90 days. A1C test shows the percentage of glucose in your blood.
What do glucose levels mean?
Glucose levels are primarily about glucose / insulin balance (also called glucose homeostasis in your blood stream. Insulin is a hormone produced by your pancreas which your body needs to burn the sugar and convert it into energy. High glucose level means that glucose / insulin balance is disturbed and may need to be corrected. Higher amounts for glucose need more insulin to be processed. Diabetes is a condition when you blood glucose levels are higher that your insulin can manage, so glucose in not burnt and its levels in the blood remain high while you experience energy shortage symptoms, like weakness or dizzness, because your body cells cannot get glucose from your blood and starve. In this state yor can also feel thirsty or urinate often.
There are two major causes for glucose / insulin disbalance. First, pancreas produces too little insulin or you have a condition called insulin-resistance (typical for type 2 diabetes), which means that glucose-lowering effects of insulin do not work for your body cells. Type 1 diabetes is less common and occurs only in 10% of all diabetes cases. This condition is caused by an auto-immune damage to the pancreas, which means that your body's immune system destroys your pancreas cells impairing its normal work.
The bottom line is, a high glucose level means that you have to take care of your diet and lifestyle, go to your doctor and also possibly check your pancreases. In most cases, high glucose levels is a warning sign that urges you to take action and change your lifestyle. A short-term high blood glucose may cause much inconveniences, like thirst, fatigue, frequent urinating or blurry vision. Normalizing your blood glucose will resolve these symptoms and prevent complications. However, high glucose levels over the long term mean that either your have diabetes, which may result in blindness, amputations, or kidney failure, or your diet is overloaded with high glycemic foods and your will most likely develop diabetes and it's complications unless you take action to decrease your blood glucose levels. Regular high glucose level readings mean than it could a be pre-diabetes condition.
