Type 1 Diabetes

Diabetes is a lifelong condition that causes a person’s blood sugar level to become too high. It is also known as diabetes mellitus.

Types of diabetes

There are two main types of diabetes: type 1 and type 2.

Type 1 diabetes is often referred to as insulin-dependent diabetes. It is also sometimes known as juvenile diabetes or early-onset diabetes because it often develops before the age of 40, usually during the teenage years.

In type 1 diabetes, the pancreas (a small gland behind the stomach) does not produce any insulin. Insulin is a hormone that regulates blood glucose levels. If the amount of glucose in the blood is too high, it can seriously damage the body’s organs.

If you have type 1 diabetes, you will need to take insulin injections for life. You must also make sure that your blood glucose levels stay balanced by eating a healthy diet, taking regular exercise and having regular blood tests.

In type 2 diabetes, the body does not produce enough insulin, or the body’s cells do not react to it. This is known as insulin resistance.

Diabetes symptoms

Diabetes can cause various symptoms, including:

  • feeling very thirsty
  • urinating frequently, particularly at night
  • feeling very tired
  • weight loss and loss of muscle bulk (in type 1 diabetes)

Causes of type 1 diabetes

Type 1 diabetes occurs because your body is unable to produce insulin. Insulin usually moves glucose out of your blood and into your cells, where it is converted to energy. However, in type 1 diabetes, there is no insulin to move glucose out of your bloodstream and into your cells.

Without insulin, the body breaks down its own fat and muscle (leading to weight loss). In type 1 diabetes this can lead to a serious short- term condition where the bloodstream becomes acidic along with dangerous dehydration (diabetic ketoacidosis).

Type 1 diabetes is an autoimmune condition, where your immune system (the body’s natural defense against infection and illness) mistakes the cells in your pancreas as harmful and attacks them.

Treating type 1 diabetes

It is important that diabetes is diagnosed as early as possible so that treatment can be started.

Diabetes cannot be cured, but treatment aims to keep your blood glucose levels as normal as possible, and control your symptoms to prevent health problems developing later.

If you are diagnosed with diabetes, you will be referred to a diabetes care team for specialist treatment. Your care team will be able to explain your condition to you in detail and help you understand your treatment. They will also closely monitor your condition.

As your body cannot produce any insulin, you will need to have regular insulin treatment to keep your glucose levels normal. You will need to learn how to match the insulin you inject to the food you eat, taking into account your blood glucose level and how much exercise you do. This skill needs to be practised and learnt gradually. Many centres now provide courses to teach these skills.

Insulin comes in several different forms, each of which works slightly differently. For example, some last up to a whole day (long-acting), some last up to eight hours (short-acting) and some work quickly but do not last very long (rapid-acting). Your treatment may include a combination of these different insulin preparations.


Left untreated, diabetes can cause many different health problems. Large amounts of glucose can damage blood vessels, nerves and organs.

Even a mildly raised glucose level that does not cause any symptoms can have damaging effects in the long term.

Living with diabetes

If you have type 1 diabetes, you will need to look after your health very carefully. Caring for your health will also make treating your diabetes easier and minimise your risk of developing complications.

Eating a healthy, balanced diet and exercising regularlywill lower your blood glucose level.

And stopping smoking (if you smoke) will reduce your risk of developing a cardiovascular disease.

Diabetes in pregnancy

During pregnancy, some women have such high levels of glucose in their blood that their body cannot produce enough insulin to absorb it all. This is known as gestational diabetes, and it affects approximately 5% of pregnant women. For people with existing type 1 diabetes, pregnancy can also make this worse.

Gestational diabetes can increase the risk of health problems in an unborn baby, so it is important to keep the levels of glucose in your blood under control.

In most cases, gestational diabetes develops in the second half of pregnancy and disappears after the baby is born.
