About diabetes
Diabetes is on the rise, with more than 5 million adults diagnosed with the condition in the UK alone, according to Diabetes UK. Around 1 in 10 people with diabetes have type 1 diabetes - an autoimmune condition in which the body stops producing insulin. However, 9 out 10 people have type 2 diabetes, usually caused by poor diet and lifestyle choices - although family history and ethnicity can also increase your chance of developing it.
Who are these questions for?
If you're concerned that you might be having some of the symptoms of diabetes - or know that you may have a higher chance of developing the condition - these questions should help you discover whether you have some of the symptoms. If you suspect you may have or may be developing diabetes, it's important to get a check-up as soon as possible.

Why low blood sugar is dangerous
Hypoglycaemia, or low blood sugar, is often known as a 'hypo'. It can make you feel unwell and affect your ability to drive. Simple steps will reduce the risk, and allow you to treat a hypo early, before it causes more serious complications.

Diabetic retinopathy
If you have diabetes, it is vital that you have your eyes checked regularly. The retina is at the back of the eye and damage to the retina (the light sensitive layer of cells) is called a retinopathy. Retinopathy is a common complication of diabetes. If left untreated, it can become worse and cause some loss of vision, or total loss of vision (severe sight impairment) in severe cases. Good control of blood sugar (glucose) and blood pressure slows down the progression of retinopathy. Treatment with a laser, before the retinopathy becomes severe, can often prevent loss of vision.

Who is more likely to develop diabetes?
Type 1 diabetes is an autoimmune condition, and as yet the triggers for this condition are unknown. However, the onset of type 2 diabetes has a number of contributing factors - including being overweight or having obesity, living a sedentary lifestyle, or eating an unhealthy, high-calorie diet.
Dr Jenna Macciochi, Doctor of Immunology at the University of Sussex explains: "With type 2 diabetes your body's still producing at least some insulin - which helps our cells to utilise glucose - but you can't respond to it. You've lost that sensitivity.
"If the system gets overworked - eating the wrong things, eating too frequently, too much - the system gets worn out and we lose the sensitivity to it."
Might I have diabetes and not realise?
With type 1 diabetes, the body stops producing insulin, meaning the effect on the body is usually rapid and noticeable. However, type 2 diabetes develops slowly - the body still produces insulin, but it may be insufficient, or the body might not respond to it properly.
This means that the development of symptoms is gradual. "Symptoms for type 1 diabetes often develop very fast," says Macciochi. "But with type 2 diabetes you may not even know you have it, as symptoms can be very subtle."

How accurate is it?
The only conclusive test for diabetes is a blood test. However, these questions should give you an indication of whether to seek urgent help, or whether to raise the issue at your next doctor's appointment.
