High blood sugar levels, also known as hyperglycemia, can cause a range of symptoms and health complications. People with type 1 and type 2 diabetes, as well as pregnant women with gestational diabetes, are at risk of developing hyperglycemia. Symptoms of high blood sugar usually appear gradually and can include glucose detected in the urine (glycosuria), increased hunger (polyphagia), and unexplained weight loss. If left untreated, hyperglycemia can lead to ketoacidosis, a serious condition in which ketones, toxic acids, build up in the blood.
To check for high blood sugar levels, your doctor or care team may ask you to take a blood or urine test. If you have diabetes, you may be advised to use a testing device to check your blood sugar level regularly at home or have an appointment with a nurse or doctor every few months. Blisters, infections, dryness, itching, discoloration, and skin abnormalities may also be warning signs of high blood sugar. To keep your blood sugar levels within a healthy range, you may need to change your treatment or lifestyle.
You may be advised to monitor your blood sugar level more closely or to test your blood or urine for ketones. Be careful with caffeine, spices, exercise, sleep, alcohol and stress as they can affect your blood sugar levels and increase diabetes complications.
