Type 1 Diabetes

What is Type 1 diabetes?

Type 1 diabetes is an autoimmune condition with no known cause or cure.

If you have type 1 diabetes your pancreas is no longer producing the insulin your body needs. Often diagnosed in childhood (although you can develop it at any time), it is one of the most common chronic childhood conditions in developed nations, and the number of cases being diagnosed is increasing each year.

Representing 10 percent of all cases of diabetes, 127,000 Australians are currently living with it. There is no cure.

Type 1 diabetes is not caused by lifestyle factors. However, following a healthy lifestyle can help you to live well with type 1 diabetes, and reduce the risk of developing dangerous complications.

Why do I need insulin?

Without insulin your body is unable to break down the glucose in the food that you eat. Glucose is your body’s main source of energy.

If you have type 1 diabetes you will need to regularly monitor your blood glucose levels and either inject insulin or use an insulin pump to replace the insulin your pancreas cannot produce.

If you don’t get the insulin you need to process the glucose in your blood your body will resort to burning fat instead. This releases dangerous chemical substances into your blood and can cause a serious condition called ketoacidosis. Meanwhile, if your blood glucose levels rise too high, you could be at risk of hyperglycaemia.

Signs and symptoms of Type 1 diabetes

Type 1 diabetes is often diagnosed in childhood, although you can develop it at any age. Being diagnosed and treated quickly is critical.

The most common type 1 diabetes symptoms are often referred to as the 4Ts which stand for Toilet, Tired, Thirsty and Thinner. If you notice these in your child or yourself you should see your doctor immediately.

Signs and symptoms of type 1 diabetes may include:

Passing urine more frequently
Excessive thirst and drinking a lot of fluids
Unexplained weight loss
Fatigue (tiredness)
Mood changes
Skin infections or itching
Oral or vaginal thrush
Abdominal pain
Excessive hunger
Weakness
Headaches
Blurred vision

If you or a member of your family are experiencing one or more of these type 1 diabetes symptoms you should make an urgent appointment to see your doctor.

Type 1 diabetes complications

There are a number of complications associated with diabetes. If diabetes is left undiagnosed or unchecked for too long, it can lead to serious and often life threatening health complications. Some of the serious complications which can arise from diabetes include:

Heart disease
Kidney disease
Vision loss and blindness
Limb amputation
Stroke
Depression, stress and burnout
Sexual dysfunction
Persistent infections

This video explains more about the health complications which are associated with living with diabetes.

It’s important to understand the complications associated with diabetes. If you have questions talk to your doctor, a member of your diabetes healthcare team or call us on 1300 342 238.

Complications specific to type 1 diabetes

Some specific type 1 diabetes complications include:

Coeliac disease

Type 1 diabetes and coeliac disease are both described as autoimmune diseases, meaning that your immune system is attacking parts of your body. While the causes of both coeliac disease and type 1 diabetes are not fully known, there is a relationship between the two. Between 4 and 10 per cent of people with type 1 diabetes also have coeliac disease.

Diabetic ketoacidosis (DKA)

Consistently high blood glucose levels can lead to a condition called diabetic ketoacidosis. This happens when a severe lack of insulin means your body cannot use glucose for energy and it starts to break down other body tissue as an alternative energy source. Ketones are the by-product of this process.

Ketones are poisonous chemicals which build up and, if left unchecked, will cause the body to become acidic, hence the name ‘acidosis’. DKA generally develops over 24 hours but can develop more quickly, particularly in young children. DKA develops when blood glucose levels are extremely high, often as a result of illness. DKA can develop rapidly and should be treated as a medical emergency at hospital.

Lipohypertrophy

If you repeatedly inject insulin into the same place on your body, you can develop a build-up of fatty tissue under the skin which is known as lipohypertrophy.
