Symptoms of Diabetes

The symptoms of diabetes may begin gradually and can be hard to identify at first. They may include fatigue, a sick feeling, frequent urination, especially at night, and excessive thirst. When there is extra glucose in blood, one way the body gets rid of it is through frequent urination. This loss of fluids causes extreme thirst. Other symptoms may include sudden weight loss, blurred vision, and slow healing of skin, gum and urinary tract infections. Women may notice genital itching.

A doctor also may suspect a patient has diabetes if the person has health problems related to diabetes. For instance, heart disease, changes in vision, numbness in the feet and legs or sores that are slow to heal, may prompt a doctor to check for diabetes. These symptoms do not mean a person has diabetes, but anyone who has these problems should see a doctor.
