4. Past use of antibiotics
A study finds that people who have taken a large amount of antibiotics are more susceptible to the disease. This is based on the premise that changing the gut flora is problematic, according to the American Journal of Gastroenterology, September 13, 2011.
As everyone’s body is different, what constitutes ‘a lot’ could vary from person to person.
Canadian researchers found that people prescribed a lot of antibiotics were up to 50 percent more likely to get Crohn’s disease. The antibiotic usage could occur in as short a time as two to five years. The study was done with 24,000 people.
This shows that antibiotic usage doesn’t just produce short-term gut flora changes.
