This can happen when the body does not make enough insulin or cannot use insulin properly.
People may need to urinate often and feel very thirsty.
They may also feel hungry, tired or have blurry vision.
Headaches, dry mouth, slow-healing cuts and repeated infections are other possible signs.
High blood sugar can happen with diabetes, prediabetes, illness, stress, some medicines or missed diabetes treatments.
Doctors can check it with blood tests, an HbA1c test and urine tests.
Healthy eating, exercise, prescribed medicines and regular monitoring can help manage it.
Severe or uncontrolled symptoms require medical attention because serious complications can develop.
