Diabetes symptoms: What’s the difference between type 1 and type 2
DIABETES is a life-long health condition which affects around 4.7 million people in the UK.
Experts estimate there are almost one million people living with type 2 diabetes who don't know it yet. But what is it exactly and what are the differences between the two types?
What is diabetes?
Diabetes is a condition caused by high levels of glucose - or sugar - in the blood.
Glucose levels are so high because the body is unable to properly use it.
In people diagnosed with diabetes, their pancreas doesn't produce any insulin, or not enough insulin.
Insulin is a hormone typically produced by the pancreas and allows glucose to enter the cells in the body, where it's used for energy.
It develops when the insulin-producing cells in the body are unable to produce enough insulin.
It can also be triggered when the insulin that is produced doesn't work properly.
Who is at risk from type 2 diabetes?
Typically, people are diagnosed with type 2 diabetes from the age of 40, but there are some exceptions.
In people from southern Asia the disease can appear as early as 25.
And the condition is becoming more prevalent in children and teenagers of all ethnicities.
Experts suggest the rising rates of type 2 diabetes is due to the obesity epidemic - a key cause of type 2 diabetes.
Type 2 diabetes can be treated with drugs, and many people can reverse their condition by adopting a healthy lifestyle.
Thousands of children and young adults under the age of 25 have been diagnosed with type 2 diabetes in England and Wales in recent years.
The Obesity Health Alliance said it was "hugely concerning"; to see so many young people diagnosed with type 2 diabetes.
What is type 1 diabetes? Who is at risk from it?
Type 1 diabetes is where the cells in the body that typically produce insulin have been destroyed, leaving the body unable to produce the key hormone.
It's far less common, affecting around 10 per cent of adults who have the disease.
It is treated with daily insulin injections or an insulin pump.
This form of the disease typically occurs in childhood, or before the age of 40 and is not linked to obesity.
One well-known sufferer of Type 1 diabetes is Prime Minister Theresa May.
She has recently revealed that she has to inject herself with insulin up to five times a day to manage her condition.
While pregnant women can also suffer from gestinational diabetes, when they produce too much blood sugar while carrying their unborn baby.
Model Danielle Lloyd has told how she suffered from the condition while pregnant with her fourth child and was told to have bed rest.
What are the treatments for diabetes?
As well as being advised to eat a healthy diet and take more exercise, both forms of diabetes can be treated using different drugs.
However, whereas a healthier lifestyle can often reverse the symptoms in people with type 2 diabetes, it does not have the same dramatic effect on type 1 diabetes.
Every person diagnosed with type 1 diabetes will have to take insulin via injection or a pump.
Some type 2 diabetics will also need insulin, though it is less common.
Those diagnosed with type 2 diabetes will sometimes need to take drugs, alongside living a healthier lifestyle.
This medication is designed to lower blood sugar levels, but cannot cure the disease.
Type 2 diabetes is a progressive condition, so worsens over time, meaning some people will need more medication to control it as it progresses.
