Three symptoms will indicate high blood sugar

High blood sugar, also known as hyperglycemia, can be caused by a number of factors. The condition can develop without any symptoms, so it is often discovered accidentally during a routine medical check-up.

Typically, signs of hyperglycemia begin to appear when blood sugar levels remain high for a long time. According to experts from Diabetes UK, it is considered so when the indicator is more than 7 mmol/l before a meal and more than 8.5 mmol/l two hours after eating. The National Health Service of Great Britain (NHS) reports that hyperglycemia in people with diabetes can be indicated by:

• unusual abdominal pain;
• nausea;
• unintentional weight loss.

In addition, severe thirst, dry mouth, fatigue and blurred vision often occur. “Symptoms of hyperglycaemia can also be caused by undiagnosed diabetes, so see your GP if you experience these symptoms,” the NHS said.

Hyperglycaemia can be dangerous if blood sugar levels become or remain very high like this for a long time. Diabetes UK explained that the amount of glucose in the blood can rise and fall throughout the day, but in people with diabetes, these changes are more significant and usually occur more often.

Doctors added that “random and mild episodes”. as a rule, it is not a cause for concern, since in this case the sugar level can be quickly brought back to normal. But if this happens regularly, ketoacidosis may occur. The most dangerous consequences of this condition are coma and death.
