People with a history of constipation could have an increased risk of developing Parkinson's disease in later life, according to a new study.
New research published in the journal Neurology from the Mayo Clinic in Rochester discovered that a history of constipation is much more common for those with Parkinson's.
Around 36 per cent of people with Parkinson's disease had a history of constipation, while just 20 per cent of people without Parkinson's were hit with the same problem.
However, a leading charity noted that it was not as cut-and-dry as the study may prove.
Director of research and development at the Parkinson's Disease Society Dr Kieran Breen said that chronic problems such as constipation and sleep can be caused by a number of other things, so the community must develop more accurate ways to diagnose Parkinson's disease at an earlier time.
He continued: "Our Monument Discovery Award is working to develop ways to identify people at greater risk of developing Parkinson's before the main movement symptoms occur.
"Early diagnosis combined with treatments that can slow or stop the progression of Parkinson's will be central to finding a cure."
