When blood sugar gets too high, a person can experience increased thirst, extreme hunger, excessive urination, and dry, itchy skin. Blurred vision, feeling tired and breathing problems are also symptoms of high blood sugar, as detailed by the Vermont Department of Health.
The medical term for high blood sugar is hyperglycemia. A person suffering from hyperglycemia lacks enough insulin in the body, and, therefore, he has a high blood glucose level. High blood sugar also can be caused by using insulin that is expired, according to the Vermont Department of Health. In addition, taking steroids, eating too much, lack of enough exercise, illness, and emotional or physical stress also can cause hyperglycemia.
Hyperglycemia makes a person feel tired because the body cannot utilize the energy from glucose that isn't absorbed by the cells. Extreme thirst may come as a result of excessive urination, says the Vermont Department of Health. If blood sugar levels are high, consider the cause and the symptoms. Some remedies for hyperglycemia include taking medication at the appropriate time each day, improving exercise, drinking plenty of water, and eating small, frequent meals throughout the day. However, diabetics should consult a doctor before making any changes in their diabetic regimen.
The consequences may be serious if hyperglycemia is not treated quickly, says the New York State Department of Health. Ketoacidosis, a diabetic coma, may result. Symptoms of that are shortness of breath, fruity-smelling breath, vomiting, nausea and an excessively dry mouth. A doctor should be consulted as soon as possible. While exercising frequently lowers blood sugar levels, a person should never exercise if his urine has ketones, which can be a precursor to ketoacidosis. Exercising with ketones pushes blood sugar levels even higher.
