Having pre-diabetes can increase chance of stroke

A new study has showed that people who are suffering from pre-diabetes could face an increased risk of stroke in the future.
With pre-diabetes and high levels of blood sugar often turning into type 2 diabetes if it is not treated on time, thought to affect around 7 million people in the UK, the research, reported in the British Medical Journal, examined the link between type 2 diabetes and future stroke, as well as cardiovascular risk factors including being overweight and lifestyle.
By exploring data from 15 separate studies involving over three quarters of a million people, they found that the association between pre-diabetes and the likelihood of stroke seems to actually depend on how pre-diabetes is defined.
Pre-diabetes is usually based on impaired fasting glucose, where a range of 70.2 to 100 mg/dl is normal and being between 100 and 126 mg/dl is believed to signal pre-diabetes. However, this study revealed that pre-diabetes based on a definition of 110 to 125 mg/dl meant there was a 21 per cent greater risk of stroke, but that people between the range of 100 and 125 mg/dl do not face a greater likelihood of stroke.
However, the researchers also pointed out that a different unmeasured factor could be affecting the results and that the quality of evidence was variable, but claimed that people with pre-diabetes should remain aware that they can be at increased risk of future stroke.
