A recent study has found that Parkinson’s disease could be triggered by a protein in the stomach that travels to the brain through the vagal nerve. Researchers found that those who had the vagal nerve removed had a 40 percent lower chance of developing the disease.
Vagotomies are often performed on those who have chronic duodenal ulcers or a gastric outlet obstruction. The Swedish study compared the medical histories of 9,400 people who’d had a vagotomy to 377,000 who hadn’t had the procedure over a 40-year period.
According to the Daily Mail, 101 people who had a vagotomy went on to develop Parkinson’s disease (or 1.07 percent) compared to 4,829 people (or 1.28 percent) who still had their vagal nerve intact. Those who had undergone a truncal vagotomy were even less likely to have developed Parkinson’s disease (0.78 percent).
Other evidence that Parkinson’s disease may start in the digestive system is the fact that many Parkinson’s disease patients report GI problems like constipation years before the onset of any Parkinson’s symptoms.
