Type 1 diabetes is a lifelong (chronic) disease in which there are high levels of sugar (glucose) in the blood.

Causes, incidence, and risk factors
Type 1 diabetes can occur at any age. However, it is most often diagnosed in children, adolescents, or young adults.
Insulin is a hormone produced by special cells, called beta cells, in the pancreas. The pancreas is found behind your stomach. Insulin is needed to move blood sugar (glucose) into cells, where it is stored and later used for energy. In type 1 diabetes, beta cells produce little or no insulin.
Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. The body is unable to use this glucose for energy. This leads to the symptoms of type 1 diabetes.
The exact cause of type 1 diabetes is unknown. Most likely it is an autoimmune disorder. An infection or some other trigger causes the body to mistakenly attack the cells in the pancreas that make insulin. This kind of disorder can be passed down through families.
Symptoms
These symptoms may be the first signs of type 1 diabetes, or may occur when the blood sugar is high:
Signs and tests
Diabetes is diagnosed with the following blood tests:
Treatment
Because type 1 diabetes can start quickly and the symptoms can be severe, people who have just been diagnosed may need to stay in the hospital.
If you have just been diagnosed with type 1 diabetes, you should probably have a check-up each week until you have good control over your blood sugar. Your health care provider will review the results of your home blood sugar monitoring and urine testing. Your provider will also look at your diary of meals, snacks, and insulin injections.
As the disease gets more stable, you will have fewer follow-up visits. Visiting your health care provider is very important so you can monitor any long-term problems from diabetes.
You are the most important person in managing your diabetes. You should know the basic steps to diabetes management:

- Losing the feeling or feeling tingling in your feet

- Stomach pain
- Headache
- Hunger
- Nervousness
- Rapid heartbeat (palpitations)
- Shaking
- Sweating
- Weakness
Signs and tests
Diabetes is diagnosed with the following blood tests:
- Fasting blood glucose level -- diabetes is diagnosed if it is higher than 126 mg/dL two times
- Random (nonfasting) blood glucose level -- you may have diabetes if it is higher than 200 mg/dL, and you have symptoms such as increased thirst, urination, and fatigue (this must be confirmed with a fasting test)
- Oral glucose tolerance test -- diabetes is diagnosed if the glucose level is higher than 200 mg/dL after 2 hours
- Hemoglobin A1c test
- Normal: Less than 5.7%
- Pre-diabetes: Between 5.7% and 6.4%
- Diabetes: 6.5% or higher
- When the blood sugar is higher than 240 mg/dL
- During an illness such as pneumonia, heart attack, or stroke
- When nausea or vomiting occur
- During pregnancy
- Check the skin and bones on your feet and legs.
- Check to see if your feet are getting numb.
- Have your blood pressure checked at least every year (blood pressure goal should be 130/80 mm/Hg or lower).
- Have your hemoglobin A1c test (HbA1c) done every 6 months if your diabetes is well controlled; otherwise, every 3 months.
- Have your cholesterol and triglyceride levels checked yearly (aim for LDL cholesterol levels below 70-100 mg/dL).
- Get yearly tests to make sure your kidneys are working well (microalbuminuria and serum creatinine).
- Visit your eye doctor at least once a year, or more often if you have signs of diabetic eye disease.
- See the dentist every 6 months for a thorough dental cleaning and exam. Make sure your dentist and hygienist know that you have diabetes.
