A condition known as diabetic ketoacidosis occurs when blood sugar levels are very high for a long period of time, notes WebMD. Symptoms of high blood sugar include dry mouth, frequent urination, and feeling very thirsty.
Type 1 diabetes patients cannot produce insulin naturally, so they are more likely to suffer from diabetic ketoacidosis, explains WebMD. The condition can also be caused by skipping a meal, illness and stress responses.
If blood sugar is high check for keytones using a urine strip, notes WebMD. If keytones are present, the patient must try to lower their blood sugar and check again. If that doesn’t work, a physician should be consulted immediately.
