Blood sugar 22 is diabetes.

If the blood sugar is 22 mmole per liter, whether fasting or postprandial, has been significantly increased, and there are typical symptoms of polydipsia, polyuria, polyphagia and emaciation, then diabetes can be diagnosed clearly. If there is no such typical symptoms, although the blood sugar 22 mmole per liter can be basically determined as diabetes, it is recommended to repeat the fasting or postprandial blood sugar test on the same day to achieve the diagnosis criteria for diabetes. For patients diagnosed with diabetes, further evaluation of islet function and liver and kidney function is needed to determine the type of diabetes and whether there are serious organ diseases. Under normal circumstances, blood sugar 22 mmol/L requires intensive insulin treatment for a period of time, and then determine the next treatment plan according to the specific situation. Of course, the standard diabetes treatment plan also needs to assess whether there are diabetes-related complications and the risk of cardiovascular and cerebrovascular diseases.
