Hyperglycemia (High blood sugar): symptoms, causes and Treatment.

Hyperglycemia or high blood sugar:

Hyperglycemia, or high blood sugar, is an excess of glucose in the bloodstream. Even when you do your best to manage your blood glucose, you may still sometimes experience highs. These highs can be dangerous if you don’t act quickly. Learn to recognize the signs of hyperglycemia (when your fasting blood glucose is above 180 mg/dL) and act. Some people who've had type 2 diabetes for a long time may not show any symptoms despite elevated blood sugar levels.


Recognize the symptoms:

✓Increased thirst
✓Urinating more often than usual, especially during the night
✓More tired than usual
✓Blurred vision

High Blood Sugar Causes

Diabetes mellitus is one of several persistent conditions causing high blood sugar levels. For someone with diabetes, hyperglycemia has many possible causes:

Carbohydrates: Eating food containing too many carbohydrates, a form of sugar. The body of a person with diabetes cannot process high levels of carbohydrates fast enough to convert it into energy. Blood sugar levels in patients with diabetes can rise within hours after eating.
Insulin control: Not producing enough insulin action (either by injection of insulin or taking medicine which stimulates the pancreas to make more insulin). People with diabetes must control blood sugar by a combination of dietary discretion, taking medication, and physical activity. When food, exercise, and insulin are not balanced, blood sugar levels rise.
Stress: Emotions can play a role in causing hyperglycemia, but should not be used as an excuse for poor control of diabetes.
Low levels of exercise: Daily exercise is a critical contributor to regulating blood sugar levels.
Infection, illness, or surgery: With illness, blood sugar levels tend to rise quickly over several hours.
Other medications: Certain drugs, especially steroids, can affect blood sugar levels.


Treatment for hyperglycemia is often a lifelong requirement especially in people with diabetes. The blood sugar levels have to be kept within the prescribed limits. Medication, exercise, diabetic friendly diet plan and monitoring the blood sugar levels constantly are an integral part of treatment of hyperglycemia. The food that is eaten must be in balance with the insulin working in the body. However, if hyperglycemia reaches dangerous levels then emergency treatment such as fluid replacement, electrolyte replacement and insulin therapy may have to be administered in some cases.
