Hyperglycemia is a condition in which excessive amounts of glucose circulates in the blood plasma. Having chronically high levels of glucose in your blood will lead to complications of diabetes over time. Blood glucose levels can also become dangerously high in the short term and cause a life-threatening situation that could result in coma or death.It is important to know what the warning signs are and how to treat it. But it's best to prevent the situation from ever occurring.


Hyperglycemia doesn't cause symptoms until glucose levels are significantly elevated---above 200 mg/dL. Symptoms of high blood sugar slowly develop over days or weeks.

Some of the signs of early symptoms diabetes are as follows:

  • Frequent Urination
  • Increased Thirst
  • Blurred vision
  • Fatigue
  • Headache

If high blood sugar goes untreated, it can cause toxic acids known as ketones to build up in your blood and urine which creates a condition called ketoacidosis. Signs and symptoms include the following:

  • Fruity-smelling Breath
  • Nausea and Vomiting
  • Shortness of Breath
  • Dry Mouth
  • Weakness
  • Confusion
  • Abdominal Pain
  • Coma

Diabetic Ketoacidosis

Diabetic Ketoacidosis (DKA) occurs when there is no insulin in your body and your body cells are unable to take in glucose from your bloodstream. This means that the body is deprived of its primary source of energy and it is forced to break down fat as an alternative energy source. During fat breakdown, toxic by-products known as ketones are produced. An excessive amount of ketones in the body can make your blood highly acidic and cause the symptoms described above.

DKA can also develop during periods of stress or illness. When the body has to deal with a bacterial infection, a sickness such as the flu, or a stressful situation, hormones cause the liver to release stored glucose. These hormones also block the effects of insulin. Untreated DKA can lead to coma and may be occasionally fatal. DKA is a medical emergency that needs to be treated in the hospital
