Hyperglycemia (hy-per-gly-seem-i-uh), more commonly known as high blood sugar, occurs when there is too little insulin to control the amount of glucose (gloo-kose) in the blood. An abnormally high blood glucose level, if allowed to continue without treatment, can result in a coma. With type 1 diabetes, treatment usually consists of diet, exercise and insulin injections. Drug treatment for type 2 diabetes may consist of diabetes pills. Both types of diabetes require diet control and exercise to help keep glucose levels in the normal range. Self-monitoring can help track blood sugar levels, and allow your health care provider to make adjustments in your treatment plan as needed. Poor and inadequate diabetes control can increase your risk of long-term complications. So, if elevated blood sugar levels are a consistent problem, it’s important to consult your physician. For further information or specific recommendations, contact your health care provider.
