Too much glucose in the blood is called hyperglycemia or high blood glucose. It can be caused by many things, for example skipping an insulin injection or taking too little insulin for the food you have eaten.
Anxiety and stress also raise blood sugar. Adrenaline has the effect of raising blood glucose,
High blood sugar is harder to sense than low blood sugar (hypoglycemia). If blood glucose is very high, a person can feel the following symptoms: headache, blurry vision, thirst, nausea, frequent urination, and dry, itchy skin.
If high blood glucose is not treated, it can become diabetic ketoacidosis (DKA), a serious condition requiring hospital treatment.
In the United States , about 30 percent of children and 20 percent of adults with T1DM find out they have the disease as a result of being treated for DKA. In the absence of insulin, glucose builds up in the blood.
DKA is always suspected if blood glucose is above 250 mg/dl and when there are ketones in the urine. Ketones are a result of the body breaking down fat for energy.
If a person has consistently high blood glucose over many years, a number of serious complications can occur. These are eye damage (retinopathy), kidney damage (nephropathy), nerve damage (neuropathy), and heart problems.
These long term complications can be prevented by keeping blood glucose within a normal range, by good diet, and exercise.
