Hyperglycemia: Definition, Symptoms, Treatment

What Should I Do?

If you have diabetes and see one of the first signs of high blood sugar, take a blood sugar test and contact a doctor. The doctor will ask for results from several examinations. He can recommend the following changes:

  • Drink more water. H20 helps remove excess sugar from your blood through urine, and helps you avoid dehydration.
  • Regular exercise. Exercise can help lower your blood sugar levels. But under certain conditions, can make blood sugar higher. Ask your doctor what type of exercise is right for you.

Caution: If you have type 1 diabetes and your blood sugar is high, you need to check ketones in your urine. If you have ketones, don’t exercise. If you have type 2 diabetes and your blood sugar is high, you also need to make sure that there are no ketones in your urine and that you are well hydrated. Then the doctor may give permission to exercise carefully as long as you feel able to do it.

Change your eating habits. You may need to meet with a nutritionist to change the amount and type of food you consume.

Change treatment. Your doctor can change the amount, time, or type of diabetes medication you are taking. Don’t make changes without talking to your doctor.

If you have type 1 diabetes and your blood sugar is more than 250 mg / dL, your doctor may want you to undergo ketone testing in urine or blood.

Emergency Treatment for Severe Hyperglycemia

If you have signs and symptoms of diabetic ketoacidosis and hyperosmolar hyperglycemic syndrome, you may need to be treated in the emergency room at the hospital. Emergency treatment can reduce your blood sugar to the normal range.

When Should I See a Doctor?

Go to the hospital immediately if:

  • You are sick and cannot eat food or liquid
  • Your blood glucose levels continuously above 240 mg / dL (13 mmol / L) and you have ketones in your urine

Check with a doctor if:

  • You have ongoing diarrhea or vomiting, but you can eat some food or drink
  • You have a fever that lasts more than 24 hours
  • Your blood glucose is more than 240 mg / dL (13 mmol / L) even though you have taken your diabetes medication
  • You have difficulty keeping your blood glucose levels in the desired range


The best course of action is to train good diabetes management and learn how to detect hyperglycemia so that you can overcome it early before it deteriorates.

The following suggestions can help maintain your blood sugar in your target range:

  • Follow your diabetes food plan. If you are taking insulin or an oral diabetes medication, it is important that you be consistent about your amount and time for heavy and light meals. The food you eat must be balanced with the insulin that works in your body.
  • Watch your blood sugar levels. Depending on your treatment plan, you can check and record your blood sugar levels several times a week or several times a day. Careful monitoring is the only way to ensure that your blood sugar level stays within the target range. Make a note when your glucose reading is above or below your destination range.
  • Consumption of drugs prescribed by a doctor.
  • Adjust your medication if you change your physical activity. Adjustment depends on the results of the blood sugar test and on the type and duration of the activity.
