How can we help?
Hyperglycemia, or high blood glucose, can be a dangerous problem for individuals with diabetes. Although hyperglycemia is sometimes defined as a blood glucose reading above 180, everyone is different — and people have symptoms of hyperglycemia at different levels.
In the short term, hyperglycemia can cause serious side effects, and may even become life threatening. For example, one sign of dangerously high blood glucose is ketones in your urine. Ketones are acids your body makes when it burns fat instead of glucose for energy. They can build up to toxic levels in your body. This condition is called ketoacidosis.
Over the long term, high blood glucose can increase your chance of diabetes complications. Without glucose, your brain can’t function. So when ketoacidosis is severe, you can go into a coma, or even die. That’s why you need to be alert to the symptoms of hyperglycemia and act right away to correct it.
Call for advice or an appointment if:
Get emergency care if you can’t reach your healthcare provider, or if you have large amounts of ketones in your urine.
Routine blood sugar monitoring with your blood glucose meter or device will help you maintain your blood sugar levels and alert you and your provider if you are at risk for developing hyperglycemia.
If needed to confirm hyperglycemia, your provider may also order an A1C test, which provides measurement of your blood sugar for the past few months.

Along with checking your blood glucose, watch out for the following symptoms:
Because hyperglycemia tends to come on gradually, you may not notice these symptoms right away. A high reading on your glucose meter may be your first sign that blood glucose levels are running too high.
Ketoacidosis may occur when hyperglycemia is severe. People with type 1 diabetes are at the greatest risk of ketoacidosis. That’s because people with type 2 diabetes usually have at least some insulin available to take glucose into the cells. Ketoacidosis symptoms include:
