Patients with diabetes mellitus mainly present with high fasting and postprandial glucose. The clinical manifestations are dry mouth, excessive drinking, and polyuria. Complications mainly include chronic and acute complications such as diabetic foot, diabetic nephropathy, and hyperosmolar coma and ketoacidosis. In general, symptoms such as dry mouth are common with a blood glucose of 13.6 mmol/L, but a short period of elevated blood glucose does not necessarily present with acute and chronic complications.
The normal normal range of blood glucose is as follows: the body’s plasma glucose level after 8 hours of fasting is between 3.9 and 6.1 mmol/L. The blood glucose level two hours after a meal should be less than 7.8 mmol/L. Random blood glucose should be less than 11.1 mmol/L. Anything above this range is considered abnormal blood glucose and abnormal blood glucose disease is present. The main symptoms of diabetic patients include dry mouth, excessive drinking and polyuria. Chronic complications such as diabetic foot, diabetic fundopathy, peripheral neuropathy, diabetic nephropathy, etc. can also occur with long-term elevated blood glucose. Patients may experience itchy skin, loss of vision and swollen eyelids. Acute complications, such as ketoacidosis and diabetic hyperosmolar coma, can occur when blood glucose rises too quickly and too high in the short term.
If the postprandial blood glucose is 13.6 mmol/L, the clinical symptoms are generally dry mouth, polyuria, and other symptoms, and acute complications rarely occur. However, patients are also required to keep their blood glucose under strict control.
