What is Type 1 diabetes Igcse?

Type 1 diabetes is a condition where the blood glucose levels are not able to be regulated as the insulin-secreting cells in the pancreas are not able to produce insulin. This means that blood glucose levels are often far too high. It can be treated by injecting insulin.

In type 2 diabetes the person’s body cells no longer respond to insulin produced by the pancreas. It is more common in older people. It can be controlled by a carbohydrate controlled diet and an exercise regime. Carbohydrate is digested into glucose, which raises the overall blood glucose level.

What is type 1 diabetes and how is it controlled?

People who have type 1 diabetes must take insulin as part of their treatment. Because their bodies can’t make insulin anymore, they need to get the right amount to keep their blood sugar levels in a healthy range. The only way to get insulin into the body now is by injection with a needle or with an insulin pump.

The main difference between the two types of diabetes is that type 1 diabetes is a genetic disorder that often shows up early in life, and type 2 is largely diet-related and develops over time.

What is Type 1 diabetes biology?

Type 1 diabetes is a disorder characterized by abnormally high blood sugar levels. In this form of diabetes, specialized cells in the pancreas called beta cells stop producing insulin . Insulin controls how much glucose (a type of sugar) is passed from the blood into cells for conversion to energy.

What is Type 1 diabetes Bitesize?

Type 1 diabetes is a disorder in which the pancreas fails to produce enough insulin. This can be detected from an early age. It is characterised by uncontrolled high blood glucose levels and it can be controlled by injecting insulin.

Is Type 1 diabetes genetic?

Family history: Since type 1 diabetes involves an inherited susceptibility to developing the disease, if a family member has (or had) type 1, you are at a higher risk. If both parents have (or had) type 1, the likelihood of their child developing type 1 is higher than if just one parent has (or had) diabetes.
