What is type 1 diabetes?
Type 1 diabetes is a disorder of the pancreas. The organ doesn't make enough insulin. It is different from type 2 diabetes. People with type 1 diabetes don't make any insulin at all. The immune system destroys important cells in the insulin production process. The onset often happens in childhood.
People with type 2 diabetes make some insulin, but the amount they make decreases over time. It usually comes on in adulthood. Eventually, they may stop producing it altogether.
However, type 1 diabetes can not be reversed, while symptoms of type 2 diabetes may be ameliorated with lifestyle changes in some cases, if they are made early enough in the progression of the disease.
While most people get type 1 diabetes in childhood or as a teenager, it can happen at any age. Symptoms include:
Type 1 diabetes is caused by an auto-immune reaction. The immune system destroys beta cells—the cells that make insulin. This removes the body's ability to produce it. Diet and lifestyle are not a factor in type 1 diabetes.
Who can get it?
Tests for type 1 diabetes
There are a few tests a doctor may perform to diagnose type 1 diabetes.
This test looks for specific antibodies that the body makes when it attacks the beta cells in your pancreas. This test is usually given to direct relatives of people with type 1 diabetes because it can help to predict whether or not someone may develop type 1 diabetes up to one year before they have any symptoms.
This test may also be given to people with close relatives who have type 1 diabetes. It can help to identify if someone has a genetic predisposition to getting the disease.
Fasting plasma glucose test
This test checks your blood sugar levels. The fasting test is taken after you have not eaten anything for eight hours. There is another non-fasted version of this test. Either one can give a snapshot of blood sugar levels to help determine if you have diabetes.
Hemoglobin A1c test
Treatments for type 1 diabetes
People with type 1 diabetes must take insulin as directed. Some people may use medical devices like an insulin pump so they don't have to inject themselves with insulin multiple times a day. Each person's schedule of taking insulin is tailored to their particular schedule and habits. Your doctor will help you figure out an insulin schedule that works for you.
They must also monitor their blood sugar levels to make sure they don't get too high or too low. People with type 1 diabetes can test using a drop of blood obtained through a finger-stick, or a wearable device called a continuous glucose monitor.
People with type 1 diabetes should wear a medical identification bracelet so first responders will know how to treat them during a medical emergency.
Complications of treatment
Taking insulin must be balanced with how many carbohydrates you eat. If you mismatch the number of carbs with the amount of insulin given, your blood sugar can get too high or too low.
