Topic Overview

Symptoms of type 1 diabetes usually happen quickly. If ignored, the diagnosis of type 1 diabetes may happen in an emergency room or hospital.

If your doctor thinks that you might have type 1 diabetes, he or she may ask questions about your symptoms, family history of the disease, and personal medical history. Questions for the medical history may include the following:

• Have you had increased thirst, increased urination, and fatigue?
• How long have the symptoms been present?
• Have you had an increase in appetite?
• Have you lost weight lately?
• Is there a family history of diabetes?
• What other medical conditions do you have?
• What medicines are you are currently taking?
• Have you been ill recently?
• Has growth and development progressed normally (if the person is a child)?

Your doctor will also give you a complete physical exam. You will continue having exams on a regular basis if you are diagnosed with this disease. The physical exam includes:

• Measuring your height and weight. Children and teens will have their height and weight compared to standards that are normal for their age groups.
• Checking your blood pressure. For adults, blood pressure may be checked while standing and sitting.
• Checking your eyes.
• Feeling your neck to evaluate your thyroid gland. Thyroid problems sometimes develop in people who have diabetes.
• Listening to your heart and lung sounds and checking the blood flow (pulses) in your arms, legs, and feet.
• Checking for signs of dehydration, such as loose skin, a dry mouth, or sunken eyeballs.
• Checking alertness, if you are very ill.
• Checking your feet for problems including corns, calluses, blisters, cuts, cracks, or sores.
