Common symptoms of diabetes include increased urination and thirst, blurry vision, fatigue and cuts that heal slowly, as described by the American Diabetes Association. A change in weight may also indicate diabetes, especially sudden weight loss, which may indicate Type 1 diabetes. Women may experience an increase in vaginal yeast infections, according to WebMD, and itchy skin can also signify the disease.
Patients diagnosed with Type 1 diabetes often have a sudden onset of symptoms, while the symptoms of pre-diabetes and Type 2 diabetes usually present themselves gradually and sometimes go unnoticed until patients undergo blood work, as Mayo Clinic explains. Tests used to diagnose diabetes include a hemoglobin A1c blood test and a fasting blood glucose test. Doctors may call for a urine test if they suspect Type 1 diabetes. Patients most at risk of developing diabetes include those over age 45, those with a family history of diabetes and anyone with a body mass index greater than 25.
Treatment for diabetes depends on the type. For pre-diabetes and Type 2 diabetes, dietary changes and exercise can often control the condition, according to Everyday Health. If diet and exercise aren't enough to control the symptoms, doctors prescribe medications such as metformin to help patients control blood sugar levels. Insulin, which doctors often prescribe to treat Type 1 diabetes, is usually a last resort for the treatment of Type 2 diabetes.
