Glucose intolerance is a term used to describe higher than normal blood glucose levels which are a result of metabolic conditions such as type 2 diabetes. Due to the lifestyles that western citizens live, it’s made glucose intolerance become more common. Your diet, hormones, medication, and stress will all have an effect on your blood glucose levels; and having glucose intolerance can make keeping track of them difficult.
Causes of Glucose Intolerance
As stated above, there are metabolic conditions that can cause higher than normal blood glucose levels which include:
- Impaired fasting glucose (IFG)- This condition is also known as impaired fasting glycemia, prediabetes, or metabolic syndrome. It can be described as when your blood glucose levels are above 6.0mmo/L whilst fasting but not high enough to be considered diabetic.
- Impaired glucose tolerance (IGT)- This is when you have a blood glucose level of over 7.8mmo/L 2 hours after you intake 75G of glucose.
- Prediabetes- This condition refers primarily to IFG and IGT. Although you hear the term prediabetes quite a lot, you will also hear the term intermediate hyperglycemia. Prediabetes can develop into type 2 diabetes, with studies showing that it develops in 25% of people who suffer from it in 3-5 years.
- Type 2 diabetes- Type 2 is the most common form of diabetes and is a disease that is caused by your blood glucose levels being too high, You do not have to be diabetic in order to be glucose intolerant, but being glucose intolerant means you’re more likely to develop type 2 diabetes. Tests are carried out to establish which you have as a treatment.
Symptoms of Glucose Intolerance
The symptoms of glucose intolerance are very similar to the symptoms of type 2 diabetes, which is another reason why the test is carried out; the symptoms can include:
- Feeling more thirsty or dehydrated
- Fatigue and tiredness
- Blurry vision
- Feeling drowsy
- Loss of muscle mass
- Frequently needing to urinate
Treatments for Glucose Intolerance
If you suspect you have glucose intolerance, you can take an Oral Glucose Tolerance Test. This is one of the most common tolerance tests and determines if you suffer from diabetes or just glucose intolerance. When you take the test, your blood glucose level is analysed before and after you drink a glucose liquid to assess how quickly your body metabolises the glucose.
The result of the test will help the doctors at Pall Mall to diagnose diabetes, as well as any other health-related issues such as insulin resistance and reactive hypoglycemia.
