Dangerously High Blood Sugar Symptoms

Prolonged high blood sugar can lead to a serious condition called diabetic hyperosmolar syndrome. Oftentimes this condition develops soon after a serious illness such as the flu. Blood sugar levels in excess of 600 mg/dL cause the blood to thicken and become like syrup. According to the Mayo Clinic, the sugar then passes through to the urine and causes the body to start releasing lots of fluids that can lead to life-threatening dehydration. Diabetic hyperosmolar syndrome may present the following symptoms.

High Blood Sugar Levels

• Blood sugar levels at or above 600 mg/dL is considered dangerous.

Frequent Urination

• A person suffering from diabetic hyperosmolar syndrome may have to urinate much more than normal. Sleep may be interrupted greatly by frequent trips to the restroom.

Increased Thirst and Dry Mouth

• As the body tries to eliminate the excess sugars, it is also releasing too many fluids from the body. This beginning stage of dehydration may cause intense thirst. Despite drinking more fluids, a dry mouth may persist.

Drowsiness and Weakness

• Having dangerously high blood sugar levels takes a toll on the body and may lead to sleepiness. Weakness may occur on one side of the body.

Loss of Vision

• Vision problems may occur when blood sugar levels spike.

Fever

• Some individuals may experience a fever of 101 degree F or higher.

Serious Complications

• According to the ADA, untreated dangerously high blood sugar levels can lead to diabetic coma and even death.
