What is high blood sugar

High blood sugar is knows as Hyperglycaemia and this means high blood sugar level. This can develop over many hours or days.

Symptoms can include:

• Feeling excessively thirsty
• Frequently passing large volumes of urine
• Feeling tired
• Blurred vision
• Infections (e.g. thrush, cystitis, wound infections)
• Weight loss.
Common Causes can be:
• Sickness

• Too much carbohydrate food at once
• Not enough insulin or diabetes tablets
• Other tablets or medicines.

Treatment for hyperglycaemia

For Type 1 diabetes

A person will need to Contact their doctor or Credentialled Diabetes Educator for advice about increasing their dosage of insulin. A person may also need extra doses of this insulin to help them manage they diabetes in order to prevent a diabetic episode (e.g. 2-4 units every 2 hours).

A person should be testing their blood glucose levels frequently, as well as your urine for ketones every time you pass urine as this will also help manage and regulate their diabetes.
Drink extra water or low calorie fluids to keep up with fluid lost by passing more urine.
You will need to contact your doctor or go to a hospital if:
Vomiting prevents you from drinking and makes eating difficult
Blood glucose levels remain high for a longer period of time than usual
Moderate to large ketones are present in the urine.
In type 1 diabetes, high blood glucose levels can progress to a serious condition called Ketoacidosis.

For Type 2 diabetes

It is normal for blood glucose levels to frequently change throughout the day. An occasional high blood glucose level is not a major problem. Although if your blood glucose level remains high for a few days and/ or if you are sick, contact your doctor or Credentialed Diabetes Educator or even a hospital.
