Having diabetes means that your body is not producing enough of the regulating hormone insulin. As a result, glucose accumulates in the blood and tissues and can cause defects in various parts of the body.

Up to 4.5% of the NHS budget is spent on treating the complications (heart disease, blindness, kidney failure, strokes) that can begin developing before diagnosis.

Symptoms may include any or all of the following: Tiredness, irritability, weight loss, feeling constantly thirsty and passing water more often, increased susceptibility to infection and poor healing.

If you feel you may be at risk of diabetes this simple home test may be advisable.
