Symptoms of diabetes

Plus a casual blood glucose equal to or higher than 200 mg/dl. Casual is defined as any time of day without relation to the time elapsed since the last meal.

The classic symptoms of diabetes include polyuria (urinating a lot), polydipsia (excessive thirst), polyphagia (voracious appetite), unexplained weight loss, tiredness and blurred vision among others.


glycaemia equal to or greater than 126 mg/dl, measured in blood taken from the vein (non-capillary). Fasting is defined as a period without having eaten any food at least eight hours before the sample.

3. A glucose value greater than 200 mg/dl, after 2 hours of an oral overload of 75 grams of glucose (drink).


An A1c or glycosylated hemoglobin test is a measure of your average blood glucose control during the previous three months.


According to the American Diabetes Association (ADA), A1c levels greater than 6.5% are considered a diagnosis of diabetes; Values between 5.7-6.4% are diagnostic of pre-diabetes and test results less than 5.6% are normal.

The glycosylated hemoglobin or hemoglobin A1c tests are similar to A1c and also evaluate long-term blood glucose control.

Can I use the glucose meter to diagnose diabetes?

Capillary glucose measurements are not accepted to diagnose diabetes. However, they are very helpful in detecting those who may have it and are unaware of their diabetic status.

We can then conduct a search for diabetes in our family members, work colleagues, friends, and neighbors who, due to their symptoms, family history, obesity and their lifestyle, should perform a fasting blood glucose test.

If this results in a result of 100 mg / dL or more, it should be recommended that you visit the doctor so that he or she can value it and order the simple diagnostic tests, either a fasting blood glucose (baseline) or an oral tolerance test. to glucose.

Similarly, any measurement of blood glucose that is determined in an individual without the diagnosis of diabetes and is very high, must be corroborated by the doctor who will ultimately issue and specify the diagnosis.
